How to make flower specimens?

Question 1: What kind of flower is this? What's your name? How to make plant specimens? Furong, I often dry flowers in two ways. One way is to flatten them and put them in the middle of the page, or if possible, put them in draft paper to let the paper absorb water. It usually takes three to five days to get well. The disadvantage is that the original three-dimensional shape of the flower may not be so good. The second is to put it in a sealed box with an orange desiccant in it. It usually takes a day or two to dry. Orange desiccant will turn blue-green after absorbing water, and orange after heating, which can be used repeatedly. The disadvantage of this is that the petals may shrink a little and the color will deepen accordingly, but the three-dimensional shape of the flowers can be maintained and kept in a sealed box without desiccant all the time. Pure hand tour, hope to adopt.

Question 2: How to make a rose petal specimen? The common way to go to school is to put it directly in the book. After a long time, it will fade and have a faint fragrance. If the water is dry, you can choose a transparent packaging bag with a beautiful card inside. The size of the card is very painful and can be used as a bookmark.

Question 3: How to make a flower specimen? I'm at school. How convenient? Put the flowers flat, put them in the book, take them out in a day or two, put them on two pieces of paper, fix the paper and dry them in the shade.

Question 4: How to make dried flowers and plant specimens by yourself? Collection and suppression device

Cutting tools: hand scissors (branch scissors), high branch scissors, saws, shovels (digging tools), etc.

Specimen holder and specimen paper: made of light and tough wood, about 43 cm long and 30 cm wide. Generally, battens with a width of about 2.5-3cm and a thickness of about 5-7mm are used for nailing, one is nailed every 4-5cm in the horizontal direction, and thick battens (about1.8cm) are nailed around. Soft and absorbent tissue paper is usually used as sample paper.

Dryer/oven: used to heat and dry samples, sometimes it can be replaced by electric heater or household hair dryer, or charcoal, kerosene and gasoline stoves.

Collection boxes and bags: The iron collection boxes (barrels) for collecting specimens have been replaced by light and practical plastic bags.

Other supplies for specimen collection and packaging: small plastic bags (temporarily storing grass and delicate plants), wide-mouthed plastic bottles (used to collect liquid for separating plant organs), small paper bags (containing flowers and fruits and plant fragments), specimen entrainment (fire-resistant nylon belt), long ropes and flat glass ropes, etc. Hand-held magnifying glass, telescope, altimeter, compass or GPS, tweezers, blades, etc. ; An optical camera or/and a digital camera, a film or/and a storage device;

Pencils, carbon pens, markers with different thicknesses,

Meter ruler, specimen field record book, label (number plate),

Diary, blank paper, etc. ; Portable computers, etc.

In addition, the preparations for field collection also include: 1) preparing commonly used drugs in the field to prevent field workers from getting sick or suffering accidental injuries, such as being bitten by snakes, and tying their legs (going up the mountain to prevent snakes and grasshoppers from biting). In addition, other daily necessities should be determined according to needs; 2) Understand geography (including preparing large-scale maps or topographic maps), topography, climate, transportation, meals, accommodation conditions and even get permission to enter the reserve to collect specimens; 3) Determine the objectives and key points of this collection, including the number of samples to be collected. Find relevant information about local plant species and communities, and bring classified reference books such as local plant list/flora; 4) If experimental materials are collected, relevant medicines and instruments should be prepared, such as silica gel (DNA material) for drying leaves and FAA fixative for fixing anatomical materials. Many short-lived flowers are easy to liquefy and break, so they should be collected as soon as possible and immediately squeezed or placed in 70% ethanol solution.

How to collect specimens

Basic requirements for specimen collection

1. Collect complete specimens. Reproductive organs (flowers and fruits) are very important in the species identification of angiosperms. Specimen collection must have flower or fruit materials, or both.

2. The length of each sample should be less than 40 cm. Collecting whole grass with plant height less than 40 cm; For shorter herbs, collect several plants, so that the collected materials can be covered with table paper. It is necessary to fold the whole plant or select the representative upper, middle and lower sections as the same number of specimens. Woody plants should choose branches with flowers and/or fruits (Figure 4). When there are multiform leaves, leaves with different shapes should be collected.

3. Each plant specimen should be collected at least 2-3 copies. In the following cases, we should consider collecting multiple specimens (3-5 specimens): when the collection site is a blank/weak area, when the collected specimens are used for exchange, when multiple specimens can show all the characteristics of the species, and when rare and important economic plants are encountered.

4. Investigate the name and use of plant soil, pay attention to the characteristics of plants and their growing environment, so as to enrich the information of plant resources. Do not collect or collect as few key protected and rare and endangered plants as possible. Better understanding, protection and utilization of plants.

5. When collecting woody plants, attention should be paid to recording the overall morphology of the plants, such as the thorns at the base of hawthorn and Gleditsia sinensis. When collecting medicinal materials, we should pay attention to the characteristics of annual, perennial, indigenous, epiphytic, rocky, evergreen and dry in winter. When collecting aquatic plants, we should pay attention to the characteristics of their special-shaped leaves; Pay attention to the color and smell of flowers.

Plant specimen collection technology

1. Collection of general plants

Two-year-old branches with flowers and/or fruits and normal growth of about 35 cm long were selected for collection. And do proper pruning to make it easy to dry and can be bound on a piece of table paper.

Woody plants generally do not need to dig roots and bark, but for species with special morphology (such as birch) or special economic value, some can be collected and attached to the specimens.

When collecting woody plants, use branch scissors or high branch scissors (Figure 5 and 6), and don't break them by hand, which will affect the beauty of the specimens, especially the trees with long and tough fibers ... >>

Question 5: How to make morning glory specimens? In daily life, there are often things that seem useless. If you make them by hand, you can turn them into beautiful works of art.

Making morning glory is not so easy. First choose a smaller morning glory, uproot it with a shovel, and wash off the soil on it. If it is a tall morning glory, cut off the extra roots appropriately.

After the morning glory to be a specimen is selected, put some absorbent papers on the table, put the morning glory on it, put some heavy objects on the paper, and change a piece of paper every day, so that the water of the morning glory will be absorbed as much as possible.

We should also choose thicker paper as composite paper, and put the dried morning glory in the right position of the table paper, which is very beautiful.

Finally, fix the morning glory with thread, write the name of the plant, the date of collection, the place of collection and the name of the collector in the lower right corner of the labeled paper, and stick these labels on the lower right corner of the table paper to make the morning glory specimen.

If you are interested, you might as well give it a try.

Question 6: How to make herbaceous specimens? First, prepare a box with a layer of desiccant (copper sulfate, which is available in general pharmacies and chemical reagent stores). Choose a sunny day, 9- 10 in the morning, when the flowers are not exposed to dew, cut the blooming flowers, put them in a prepared box, put them on a desiccant, and then carefully pour a small amount of desiccant into it to fill every gap between petals. Note that it is very important to keep the gap between the petals of the original flower in order to preserve the flower shape. Because some flowers, such as chrysanthemums, roses, azaleas, orchids and so on. Each layer has dense petals and tiny gaps, so it is really not easy to fill it with desiccant without crushing the flower shape.

When the whole flower is completely surrounded by desiccant, cover the box and seal it with plastic bag and plastic tape. It can be taken out in a few days (the number of sealing days depends on the thickness of petals). At this time, the flowers are dry, fragile and easily broken. Be careful when you take them out. After taking them out, turn them upside down and let the desiccant fall from the flowers. After the desiccant is completely removed, the dried flower specimen is completed.

In order to prevent dried flower specimens from absorbing moisture, they must be placed in a box with desiccant and sealed.

Question 7: How to air-dry a bunch of roses as a specimen? You can find two white tiles, two iron clips and two pieces of tissue paper.

Spread a piece of tissue paper on the white tile and put the flowers on it as a specimen. If it is an open flower, cut it in half, remove the stamens, rinse the brightly colored side, and then press the tissue paper on another tile and clamp it together with iron clips. Put it in the microwave oven, heat it for a few seconds, then take it out, put the tissue paper and flowers in a big dictionary, and put a heavy object on it. In a week, you can make a specimen.

Question 8: How to make a specimen of another flower to find another complete flower, preferably with both roots and leaves? The expansion of the factory shall not exceed A4 size. Dig down the plants carefully. Carefully clean up the sludge and remove the dead leaves. Spread the plants on A4 paper. Cover another piece of A4 paper. Carefully move the sample into the newspaper. Nail the two openings of the newspaper. Mark and label the opening. Put about ten old newspapers on the dry floor and fold them neatly. Put the newspaper with the specimen on the newspaper pile, with the folds facing each other for easy identification. Put the newspaper with samples on the newspaper pile.

Put more newspapers on it. Press boards and weights on the whole stack of specimens to help them dry and shape.

On 1, 2, 3, 5 and 7 days, the absorbent newspaper in the specimen room was changed to facilitate the drying of specimens. Submit the sample together with the outer newspaper and label on the specified date.
