Cliff seedlings in Wei Zi

Podocarpus can be planted in the yard or potted.

A, Podocarpus planting knowledge:

Luo Hansong, who likes warm and humid semi-cloudy environment, has poor cold resistance, is afraid of waterlogging and direct sunlight, and requires fertile sandy loam with good drainage.

1, propagation: common sowing and cutting propagation. Sow, sow immediately after seed collection in August, and germinate in about 10 days. Cuttings are carried out in spring and autumn. Dormant branches are selected in spring, and semi-lignified shoots, 12- 15 cm, are selected in autumn, and inserted into a seedbed with half sand and half soil to take root in about 50-60 days.

2. Transplanting: It is best to transplant in March-April in spring. Small seedlings need soil, big seedlings need soil balls, and potted plants can also be used. After planting, water it and make it permeable. Keep the soil moist during the growing period. In the hot summer season, it should be maintained in the shade. Fertilize in February every year 1 time. Winter potted plants should pay attention to cold protection, pots and pans can be buried in the soil to reduce watering.

3, planting management:

Luohansong likes warm sun, but he likes to be born in semi-humid environment and loose fertile acidic soil with good drainage medicine, and is slightly cold-resistant. Podocarpus ocellatus in the middle and lower reaches of the Yangtze River can overwinter in the open field, while Podocarpus microphyllus and Podocarpus ocellatus need to overwinter in the sunny shelter, otherwise they will easily freeze to death or burn their leaves. It is most suitable to transplant in March in spring. When transplanting, small seedlings need soil, big seedlings need soil balls, or potted plants. Plant in the yard 1 year 1 time. Potted Podocarpus is not suitable for large pots, and it is not suitable to apply more chemical fertilizers, so as not to flourish. Spray water 1 time to the trees every few days, clean the branches and leaves, and keep the soil in the basin semi-moist. Potted plants placed indoors should be moved outdoors to see the sun every 3 ~ 4 days; If left indoors for too long, the leaves will turn yellow or even fall off. Potted plants that overwinter in the greenhouse should leave the room when the outdoor temperature is stable at 65438 00℃; Summer is not suitable for high temperature exposure, so it needs to be placed in a semi-shady place. Control the amount of water after entering the house in winter. After leveling the ground, spray 0.5% carbofuran and 50% carbendazim wettable powder to disinfect the soil and eliminate underground pests and diseases.

Second, the main points of potted Podocarpus:

1. Prepare the soil for transplanting seedlings: put the prepared culture soil into the seedling pot, dry it by sunlight, and turn over the soil with a shovel every once in a while (10 day or 1 month) to water it. After a long time, the soil in the basin is loose and can be put into the basin, which has good fertilizer and water retention performance and is very suitable for the growth of general species with weak roots.

2. Transplanting without damaging the roots: before planting, loosen the pot soil with a spatula, and shovel out one third of the culture soil for later use. Then remove the cuttings of Podocarpus, gently shake off the excess sand, put the complete root system and the plant into the pot, add part of the culture soil shoveled out of the original pot, water and straighten it, and then spray water to combine the soil with the root system to maintain a good aggregate structure. This is a key step for the survival of the first plant.

3. Dilute fertilizer maintenance: After the cuttings are transplanted into the pot, watering can be used for daily management, and dilute fertilizer water can be applied once after 30 days. Usually, through inspection and patrol, we can find problems and flexibly grasp the supply of fertilizer and water. Under normal circumstances, the strong seedlings are applied more, and the weak seedlings are applied less or not. It should be placed in a place with good light and ventilation to provide a good ecological environment for plant growth, so as to achieve the purpose of living planting.

Propagation and cultivation of Podocarpus

It can be propagated by sowing and cutting. The germination rate of seeds is 80 ~ 90%; When cutting, it is best to do it in the rainy season, so it is easy to take root. Spotted leaf varieties such as' Yinban' Podocarpus. Tapiscia sinensis can be propagated by cutting. When planting, if it is a big tree over the strong age, it must be transplanted with soil balls in the rainy season. Podocarpus is more resistant to shade, so the lower branches are luxuriant and resistant to pruning.

Lohan pine trees are lush, beautiful and elegant, and the old branches are lined with stones, which is even more antique. Properly maintained, the four seasons are bright green and can be viewed, especially in early summer. Luohansong, bamboo and stone form a small scene, but it is also elegant. Jungle-style bonsai of Podocarpus, with grazing scenery, is more interesting.

It belongs to Podocarpaceae, Podocarpus. Small evergreen tree with dark gray bark and scaly cracking; The trunk is straight and the branches are flat and dense. Leaves alternate spirally, strip-lanceolate, ribbed protrusions on both sides, dark green on the surface, yellow-green on the back, and sometimes white powder. Flowers bloom from April to May. The seed is drupe-shaped, ovoid, purple when mature, like a head, a cassock and a robe, hence the name "Luohansong".

Artificial propagation of Podocarpus: usually by sowing and cutting. Cutting can be divided into two types: spring cutting and autumn cutting. Spring cutting is in the middle of March. Select robust annual branches with the length of 8- 12 cm, remove the leaves below the middle, and cut the cuttings into 4-6 cm depth. After cutting, the seedbed should be shaded, and the soil should be watered and sprayed frequently to keep it moist. Under careful management, it can take root and sprout in about 90 days. Autumn cuttings are carried out in July and August, with semi-lignified shoots as cuttings, and the rest are planted in spring. Plastic film should be used to prevent cold in winter. March in spring is most suitable for seedling raising and transplanting, and more soil or soil balls should be brought.

Podocarpus is sown and propagated in late August, and the seeds are collected, taken out from the seed holder, sown at the time of collection, or stored in the shade until spring sowing in February-March of the following year. Row spacing of drilling 15cm, soil thickness after sowing is about 2cm, covered with straw, and shaded by shed after emergence. Spring sowing seedlings should stop fertilizing in September, and autumn sowing should pay attention to winter cold protection measures, and no fertilization should be applied in that year. Seedlings usually stay in bed for one year, and then transplant to cultivate big seedlings.

Wild excavation of Podocarpus: There are wild Podocarpus distributed in the mountainous areas of the south of the Yangtze River. You can look for small old trees that grow in the canyon. Those with short plants, swaying branches, vigorous Gu Zhuo and graceful posture can be excavated. First, they should be planted in the wild. When the roots are well developed and the new branches and leaves are flourishing, they should be transplanted into pots for processing and modeling, making them excellent bonsai treasures with both rigidity and flexibility.

Luo's basin choice: Luo usually uses purple sand pottery basin or glazed pottery basin. The shape of the basin is basically the same as that used for five-needle pine, but it is slightly deeper.

Podocarpus soil: Podocarpus requires fertile and moist slightly acidic sandy loam with loose texture and good drainage. Potted plants usually use mountain soil or humus mixed with sand.

Planting Podocarpus: In March and April in spring, Podocarpus should be planted before germination. Podocarpus seedlings dug out of the ground should be covered with soil, and attention should be paid to cutting off dead roots and spreading fibrous roots. When planting, it is necessary to prevent the basin soil from sticking to the roots. The location requirements of potted plants are also roughly the same as those of five-needle pine.

Podocarpus processing: the shape of Podocarpus bonsai is mainly climbing, combined with proper pruning. It is suitable to climb and tie knots in dormancy, tie knots with brown silk, pay attention to the method of tying, make the brown not obvious, and strive for a natural posture, bent trunk and bent branches. Layering leaves by pruning. Podocarpus is very resistant to pruning, especially Tang Guo Podocarpus, which has dense branches and small leaves and can be processed into various forms. Now, in order to climb conveniently, the branches are all curved and often wrapped with iron wire. After climbing and forming, brown silk or metal wire should be removed in time to avoid wire entrapment. In the process of Luohansong's machining and modeling, we can also raise the roots year by year by turning over the pots to reach the posture of hanging the roots and exposing the claws. In addition, you can also attach stones to shape the posture of eagle claws holding stones.

Podocarpus: Podocarpus has great plasticity and can be made into various tree shapes, such as straight stem, bent stem, inclined stem, horizontal stem, cliff, root-lifting, stone-attached and so on. By bonding and shearing, it can be made into sheet or hemispherical shape. Elegant and elegant, simple and vigorous.

Placement of Podocarpus: Podocarpus should be placed in a warm, humid, semi-cloudy and semi-sunny place. In areas where the temperature is below 0℃ in winter, it must be placed indoors. In summer, when the weather is hot, attention should be paid to scaffolding for shading.

Watering Podocarpus: Podocarpus should keep the basin soil moist and free of water, and it is best to spray foliar water frequently in summer to keep the leaves bright green.

Podocarpus fertilization: Podocarpus should use cake fertilizer, manure and other organic fertilizers. Fertilization time should be carried out in spring and should not be concentrated. Don't fertilize in autumn, otherwise the autumn buds will germinate and freeze easily.

Pruning of Podocarpus: Podocarpus can be pruned at any time, mainly by cutting short long branches and keeping a certain tree shape. When flowering, it is best to pick flowers in time to avoid the influence of fruit hanging on the tree.

Podocarpus: Podocarpus bonsai should be turned over every 3-4 years to germinate in March-April in spring. When turning over the basin, remove the old soil about 1B2. Cut off the dead roots, spread out the fibrous roots, plant them in a larger pot, and replace them with fertile and loose humus to grow.

Three, Podocarpus pests and diseases:

Mainly harmful to leaf spot and anthracnose, spraying 500 times of 50% thiophanate-methyl wettable powder. Insects include scale insects, red spiders and giant salamander, and 40% omethoate EC 1500 times can be sprayed.
