Cultivation Techniques of Zygocactus trurncatus Crabmeat is also known as Crabmeat Lotus, Finger Flower, Crabmeat Orchid, Crabmeat Orchid, Cactaceae, Crabmeat Orchid. Because it blooms at Christmas, it is also called "Christmas flower" in the west. It is an ideal indoor potted flower in winter. On the sunny windowsill, the crab claw orchid hangs like an umbrella, full of brightness and beautiful curtains. (1) Morphological characteristics and varieties of perennial evergreen plants. The base of old plants is often lignified. Deteriorated branches and stems are flaky, with dark purple-red surfaces and many branches, often drooping in clusters and extending in all directions, with short internodes and obvious nodes. The metamorphic branches are divided into many small segments, 4 cm ~ 4.5 cm long and 1.5 cm ~ 2.5 cm wide, with sharp teeth at both ends and edges, like crab claws, and the central skeleton is obviously prominent. From winter to early spring, it blooms at the top of the stem node and is symmetrical on both sides. There are different varieties, such as pink, crimson, white, orange, yellow and so on. The flower tube is light brown, with four corners, and the perianth is 3-4 rounds, stacked in a tower shape. Petals open and roll, 6.5 cm -8 cm long, with 2-3 bracts at the base, petal-shaped, extending horizontally outward. Because the corolla droops and grows, it can pollinate itself. Pear or oval, smooth and dark red, as shown in Figure 3- 13. 19 18 Since the discovery and cultivation of Crab Claw Orchid, more than 200 horticultural varieties have been cultivated through hybridization, with rich color changes and various lace varieties. As long as the cultivation and management are proper, a grafted plant cultivated for several years can bloom 200 ~ 300 flowers at the same time, which is very spectacular. In the same genus; There are red flowers and lavender stems. The beautiful crab claw orchid (Z. delicatus) has white buds and pink flowers when it opens. Crab claw orchid (Z. altsteiniii) has magenta flowers and is thriving. (2) Ecological habits are native to tropical forests in eastern Brazil. In the natural environment, it is often attached to the trunk or covered in a wet valley, and the branches droop to form a hanging shape. I like warm, humid and semi-cloudy environment, and the soil needs fertile humus and peat. The suitable temperature for growing period is 20℃~ 25℃, and it is not cold-tolerant. The temperature in winter is not lower than10 c (3). The propagation methods are cutting, grafting and sowing. Cutting can be carried out in spring, and it is easy to take root by cutting the deformed stems with full growth. But after cutting off the stem, it must be placed in the shade 1 ~ 2 days, and then inserted into the sand bed after the incision is slightly dry. After insertion, the humidity should not be too high to prevent the incision from rotting, and it can take root after 3 weeks. For example, in order to cultivate umbrella-shaped chlorophytum and increase its ornamental value, grafting propagation is generally adopted. Compared with cutting, grafting propagation grows vigorously and blooms early. Grafting is best in spring and autumn. Because the temperature is suitable, the survival rate is high. When grafting in hot and humid season in summer, the incision is easy to be infected and rotted, and the survival rate is low. Cactus plants can be used as rootstocks, but pitaya and cactus with long leaves are the best. When grafting, select a robust and plump plant with a height of 30 cm as the rootstock, cut off the top 10 cm, leave 20 cm, cut into a wedge, and then enrich the crab body. In order to prevent scions from slipping, pins or cactus thorns can be inserted and fixed, and some rootstocks can be grafted with 2 ~ 3 scions. For example, if cactus is used as the rootstock, a slit is longitudinally cut at the top of the rootstock, and then the cuttings cut at the lower end are inserted, bound with thin plastic film strips, or fixed with cactus thorns. After grafting, it should be placed in a cool place to maintain a high air humidity. After about 10 days, if the scion remains stiff and bright green, it has healed and survived, which needs careful maintenance. After 1 month, wire hoops can be set up to make the scions evenly put on the shelves and gradually put them in sunny places for normal management. (4) Cultivation techniques Crab claw orchids like semi-cloudy and semi-humid environment. Potted soil requires good drainage, loose and breathable fertile soil. In summer, it is necessary to shelter from the sun and rain, and it is best to put it under a well-ventilated window, balcony or eaves. Dry, hot and poorly ventilated air is the most unfavorable to the growth of Crab claw orchid, which often leads to the spread of red spider, the growth of damaged plants is poor, the deformed stems shrink and fall off from the base. To prevent the harm of red spider, we should mainly improve the ventilation conditions. After the onset, it can be killed with 0.8Be stone sulfur mixture. Thin liquid fertilizer can be applied during the growing period, and the fertilizer and water will last from autumn to flowering. You can move when it gets cold in autumn ... >>

How to Prune Crab Claw Orchid

Crab claw orchids are easy to prune. First, determine how many layers of shelves to build, preferably three-layer pagoda-shaped brackets. Then the main branches are allocated about 6 at the bottom, 4 in the middle and 3 at the top. 2-3 years to complete. Each branch is divided into 2-3 branches, and the branches branch outward. Form radioactive branches and droop. In the process of branching, thin leaves should be properly removed (fingernails can be pinched off, and iron tools such as scissors are generally not needed), and robust leaves should be selected to cultivate the reasonable distribution of branches.

How much should I cut the crab claw orchid after pruning?

The pruning, bud thinning and bundling work of lodging crab claw orchid includes: after the flowers wither in spring, 3 ~ 4 stems are cut from the residual flowers in time, and some old stems and over-dense stems are removed at the same time, which is beneficial to ventilation and home maintenance; In the cultivation of crab claw orchid, sometimes 4 ~ 5 new branches will grow at the top of a node, and 1 ~ 2 branches should be deleted in time; There are too many weak buds on the stem nodes, so it is necessary to pick some to make the flowers of the same size and bloom vigorously; For plants cultivated for 3 ~ 5 years, 3 ~ 4 thick lead wires can be used as pillars, inserted into the soil along the basin wall, tied into 2 ~ 3 layers of circular brackets at the upper part, and tied tightly with branches on the rings to avoid overlapping and scattering of stem nodes, and at the same time, some irregular stem nodes can be deleted to make the plants umbrella-shaped, which is beneficial to photosynthesis and display and appreciation; In order to control the plant shape to be too large and make it suitable for indoor furnishings, when the canopy diameter of the whole plant reaches more than 50 cm, the stem nodes can be shortened in spring, and some old and dense branches can be thinned, so that the new branches after thinning will appear green and vigorous, and the flowers will be more lush. It is worth noting that pruning should be done in sunny days, not in rainy days or summer. The following aspects should be paid attention to in fertilization of Crabapple Orchid: after flowering in March, the dormancy period of Crabapple Orchid is short, so fertilization and water control should be stopped until new buds appear on the stem nodes, and then normal water and fertilizer management should be carried out; Applying dilute nitrogen fertilizer once every half month in the growing season does not pollute the stem nodes, which is beneficial to the vegetative growth of deformed stems; Crab claw orchids can be changed once every two years, usually from March to April. In addition to adding sand and gravel with a thickness of about 3 cm at the bottom of the basin to facilitate water filtration, rotten bird and pigeon droppings and broken bone scales with high phosphorus content should also be added to the culture soil, but the roots should not be in direct contact with fertilizers. When the temperature is higher than 30℃, plants will enter a semi-dormant state. At this time, we should not only avoid sun exposure and rain, but also put it in a damp and cool place. At the same time, we should stop fertilization and water control to prevent plants from rotting roots. Autumn and winter are the bud-bearing flowering periods of Crataegus pinnatifida, with less sunshine in late September and sufficient sunshine in mid-late June. 10 can promote flower bud differentiation and more pregnant buds. At this time, it is appropriate to topdressing liquid fertilizer with phosphorus every 7 days to 10 days, and stop fertilization after flowering.

Rest now will definitely affect the flowering of the trimmed place.

How to nurse the crab claw orchid after flowering? Do you need a trim?

In March, the flowering period of the crab claw orchid has passed and it is about to enter the dormant period. Crab claw orchid usually has dormancy twice a year, once after flowering and once in summer: summer dormancy is forced to enter physiological dormancy due to climate reasons; Dormancy after flowering is because flowering consumes a lot of nutrients and vitality, and it takes some time to recuperate.

Crab claw orchid is about to enter dormancy, and the stems with flowers may become soft and wrinkled due to excessive consumption of nutrients. At this time should be:

1, immediately remove all remaining residual flowers and trim the flower stems moderately:

Cutting off all thin, wilting and overgrown stems and shortening the overlapping stems can not only concentrate nutrition on the strong branches left after pruning, but also enhance the ventilation and light transmission of plants and reduce pests and diseases; After pruning, the plants can sprout stout new stems in the future, which is beneficial to the flowering of pregnant buds in autumn.

2. Soil replacement:

After pruning, the crab claw orchid comes out of the pot, and the residual soil at the lower part of 1/3- 1/2 is removed. Combined with root cutting, the rotten roots, rotten roots and some aged roots are cut off and replaced with new culture soil (the culture soil of crab claw orchid requires good air permeability and is beneficial to drainage. It is best to use loose and fertile soil such as peat soil and pine needle soil as medium, and a handful of granular compound fertilizer can be put in the soil as base fertilizer. Be careful not to let the fertilizer directly contact the root system. The new soil will increase the nutrient elements in the basin and reduce harmful substances, which is beneficial to the germination and growth of plants.

3. Put the potted and watered crab claw orchid in front of the sunny south window sill for maintenance. It is required to keep warm and freeze-proof, and open the window for ventilation in time. Pot soil should be dry and wet, and a little dry is better. Water is often sprayed on plants to keep the stems bright. After the dormancy period, the crab claw orchid will sprout new buds and grow new stems. After that, water and fertilizer can be strengthened and transferred to normal management.

4. Crab claw orchid needs proper shade when it enters midsummer, and it can receive bright scattered light in the morning and evening to avoid direct sunlight.

5. When the temperature drops in autumn, the crab claw orchid enters the bud stage again, so it needs enough sunshine to avoid direct blowing of cold air. At the same time, according to the needs of plant type, those stems with irregular growth should be moderately pruned. Some hypertrophy stems grow more than one bud, and the weak and emaciated buds should be removed, so that nutrition can be concentrated, and the stems are green and full, and the flowers are huge and full, so that some buds will not wither before opening because of insufficient nutrition.

6. Fertilization: Autumn is the peak season for the growth of Crab claw orchid, which can be topdressing once every 7- 10 days: granular compound fertilizer is buried in the topsoil and gradually dissolved into the soil with watering; It is best to water the decomposed manure (pig, cow, sheep manure, chicken, pigeon manure, etc.). ) at the ratio of 1:30. Spraying plants with 1000 times of urea+potassium dihydrogen phosphate aqueous solution every week from the end of10 to promote the formation and expansion of flower buds. Irrigation with 1000 times of calcium superphosphate and potassium dihydrogen phosphate aqueous solution also has the same effect.

Do the above management well, and in winter and next spring, you will see a gorgeous crab claw orchid.

Crab claw orchid grows and develops in spring, enters summer and stops growing. After the hot summer, the temperature in autumn began to drop gradually, and the weather was cool, connecting to a peak season suitable for the growth and development of Crab claw orchid. Properly managed in autumn, the growth of begonia will even exceed that in spring. The main work at this stage is to irrigate water and fertilizer reasonably and timely, which has great influence on the growth and later flowering of begonia. Too dry will affect the growth of crab claw orchid, too wet will lead to rotten roots, and too much fertilizer and water will cause excessive growth and affect the flowering of pregnant buds. Therefore, it is very important to master the word "degree". The key points of autumn management are as follows:

After watering, the temperature is still high in late summer and early autumn, and the crab claw orchid has not recovered from its summer sleep, so it can keep the soil dry. From Mid-Autumn Festival to late autumn, the weather is cool and the temperature difference between day and night is large, which is the peak season for the growth of crab claw orchid. During this period, the soil in the basin should always be moist, and excessive bathing and drying are not allowed for a long time. Plants need water for growth and development. Without water, plants will stagnate or grow slowly. Therefore, the basin soil of crab claw orchid should not be excessively dry during the autumn growth period.

Watering depends on the wet and dry conditions of the basin soil. Wait for it to dry before watering it. Before watering, loosen the soil, then water it, and then pour it thoroughly, so that the basin soil can absorb water and be wet. You can't water half a pot. If the surface is wet and the middle part of the pot soil is still dry, then the planting is still thirsty and will die after a long time. Water before evening in order to drive away the heat in the basin and reduce the temperature of the soil. The small soil in the basin is easy to dry down in Qin Ying, but the big soil in the basin is not easy to dry, so water should be less and the amount of water should not be too large.

After fertilization, the crab claw orchid began to accelerate its growth in autumn, so it must be supplemented with nutrients in time to make up for the nutrients consumed by growth. Mid-autumn to late autumn is the time when the crab claw orchid grows leaves, and nitrogen fertilizer should be mainly used, usually once every 7 ~ 10 day. It is best to use liquid fertilizer decomposed by animals and plants as fertilizer. This liquid fertilizer should be mixed with water, diluted with 65,438+0: 6 ~ 8, applied in sunny evening, and watered the next day to remove harmful salt in the soil. When the temperature dropped to 65438 05℃ in late autumn, the growth of hawthorn tended to stop and gradually entered the bud stage. At this time, we can apply phosphate fertilizer to hawthorn, such as spraying potassium diazophosphate with the concentration of11000, applying granular compound fertilizer in potted soil, or adding less phosphate granules in topdressing. At this time, the concentration of potassium diazophosphate is still 65433. Don't fertilize during flowering.

Crab claw orchid is a short-lived flower. It takes 6-8 hours a day to bloom in winter and spring. It is especially beneficial to accept the sunshine from the west at ordinary times. When the temperature is lower than 15℃, the crab claw orchid can be moved to a sunny place indoors to get as much sunshine as possible. Rotate the basin frequently, so that all parts of the crab claw orchid can receive uniform sunshine and ensure the balanced development of flower buds.

The potted crab claw orchid with sparse buds and pruning requires full and complete plant shape and neat and symmetrical edges of each leaf layer. Only in this way can there be beauty, so pruning is necessary. Pruning can be carried out when the growth of crab claw orchid stops, and the leaves or some stem nodes that are too long or too dense and messy can be removed to keep the plant shape neat and complete. Another purpose of doing this is to accumulate nutrition for pregnant buds.

If the nutrient status of the crab claw orchid is good, buds will grow on the leaves in each node or middle, not the more buds, the better. In order to ensure the normal development and consistent development speed of buds, it is necessary to dilute some buds, keep a strong bud on each node, and dilute other buds, as well as buds on other leaves. Its purpose is to save nutrition, concentrate the supply of buds left at the node end, make the buds grow, make the flowers uniform in size and bright in color.

Flowering management: the crab claw orchid does not fertilize during flowering, just keep the soil moist, and the indoor temperature should not be too high. Keeping it at about 65438 05℃ can prolong the flowering period. If the temperature is higher than 20℃, the flowers will wither ahead of time because of the high temperature. Not suitable for long time in the sun. Too much sunlight will also make flowers wither ahead of time.

After-flower management, after all the flowers of Crab claw orchid wither, it enters a hibernation period, but this hibernation period is not long, usually about a month. At this time, the stem nodes of the crab claw orchid are soft and wrinkled. At this time, the stem nodes can be trimmed appropriately, and only one or two nodes can be trimmed. The pot soil should be dry, placed in a sunny and ventilated place, and often sprayed on plants. When new leaves grow at the end of dormancy, normal management can be carried out.

Besides scale insects, the most common pest of crab claw orchid is scale insects. This pest is most likely to be found in an environment with poor ventilation in winter. When insects are found, they should be removed immediately with utensils or scraped off with bamboo pieces or nails. If the pest is serious, 80% dichlorvos emulsion 1000 ~ 1500 times, or 40% dimethoate emulsion 1500 times, or soap powder with a concentration of 1: 1000 times can be sprayed with water. ...& gt& gt

How to prune the crab claw orchid after flowering

Just don't trim it too much. It's usually grafted.

If it is long, you can cut it short. Trim according to aesthetics.

How to trim the roots of crab claw orchid? Thank you.

Generally speaking, you shouldn't trim the roots easily. If the root system is underdeveloped, there is no need to prune, and the roots should be pruned as little as possible. If you are worried about diseases carried by the roots or moving the flowerpot, you need to trim the roots. After pruning, you need to dry the wound and don't water it for a short time.
