How to reproduce gastrodia elata asexually? Is there any good way?

Key points of asexual propagation of Gastrodia elata:

First, the preparation and treatment of planting gastrodia elata.

According to the planting instructions 1 m2 Gastrodia elata:

1, wood. A wooden stick with a diameter of 4-65,43438 cm (if it exceeds 8 cm, it should be divided into two) and a length of 60 cm, which is about 65,438+00, is enough. Fresh sticks or sticks that have been cut for less than three months can be used, and each stick is cut with four oblique mouths (that is, fish scales); Except pine and fir trees, other miscellaneous trees can be used, but green bars, chestnuts, chestnut trees, fruit trees and poplars are the best.

2, thin branch fork. A twig with a diameter of 0.5-3 cm weighs about 4 kg.

3. Leaves. Deciduous leaves of any tree species, including mixed needles (commonly known as loose hairs), can be used. Before use, it needs 2 kilograms to be crushed or cut into small leaves, and it can be used after being soaked in water.

4. Soil quality. Mountain sand and river sand can be directly used in fields and slopes that have not been fertilized with farmyard manure. If you choose the field where crops were planted that year, you must turn it over to 30 cm thick to grow gastrodia elata.

5. Strain. Armillaria mellea mycobacteria 1 kg, dig out or cut the bottom of the bottle, pour out the mycobacteria, and disperse them into individual ones for later use.

6. Gastrodia elata. About 0.5 kg.

Second, the planting time and site selection

The mountain area is suitable for 300-2600 meters above sea level, and low-altitude areas such as basins and plains require indoor, shade sheds, basements, caves and other places that can shade and cool down.

Third, border construction.

Indoor flat cultivation can be divided into side ponds with width of 80 cm, height of 20 cm and unlimited length by bricks or boards. The slope boundary should be built in fields or mountains, with a depth of 10-20cm, a width of 80cm and unlimited length, which is convenient for operation. The distance between frames is 50cm, which is convenient for digging drainage ditches and walking.

Fourth, sowing and cultivation.

Place thick leaves at the bottom of the frame with a thickness of 5cm, place thick branches one by one with an interval of about 2cm, horizontally or vertically, with the incision upward, fill sand until the epidermis of thick branches is flat, but it can't cover the epidermis of thick branches, spray water until the sand is soaked, sprinkle a layer of thin leaves to cover the thick branches, sow branches at intervals of 6cm, and sow hemp seeds at intervals of 10. Spread loose hair until the surface of the stick is flat. Don't press too hard. The requirements are relaxed. The stick is covered with a twig fork about 3-5 cm, and the covering soil is about 15 cm thick. Leave the branch alone when it opens, it can play a role in ventilation. After the cultivation, people with water source spray a spray of water to let some sand penetrate into the twig fork, and then add some sand to keep warm and moist.

The above is a single-layer planting method and a double-layer gastrodia elata planting method. Other planting procedures are the same, except that after spreading a thin layer of branches, it is not necessary to cover the branches with 15cm thick soil, just cover the branches and spray some water, and the soil layer will fall down. After filling the soil until the surface of the fork is smooth, plant another layer according to the first layer method, cover the fork, and cover the sand with 15cm thick soil. After training, it is completed. The above is a one-step planting method. However, in the proper season, planting Armillaria gastrodia elata and then planting gastrodia elata seeds can adjust and rationally use the labor force in the idle season and achieve the same effect.

Key points of verb management (abbreviation of verb)

1. temperature: the outdoor growth of gastrodia elata is dominated by natural temperature, the optimum temperature is 30㎝ below the soil surface 10-26℃, and other temperatures are dormant. In the soil layer, the short-term low temperature tolerance of Gastrodia elata is subject to the weather forecast, outdoor -30℃-33℃, indoor-10℃. Short-term high temperature resistance of 40 degrees. Therefore, in winter, the soil surface should be covered with a thin layer of weeds or dead leaves, and then covered with a layer of film, which covers more than 20 cm of weeds to keep warm, moisturize and prevent freezing. When winter goes and spring comes, when the ground temperature is stable above 10 degrees, remove the film and let the rain naturally soak and wet. Gastrodia elata planted in spring need not be covered with plastic film, but should be covered with grass to shade and moisturize.

2. Moisture content: in the year of drought and flood disaster, if it lasts for more than 20 days, it is necessary to strengthen the protection work; After half an hour of heavy rain in the waterlogging period, it is best to cover the film to let the water drain into the ditch, and the weather will open immediately, so as to preserve moisture and drain waterlogging and carry out comprehensive management. In June, July and August, Gastrodia elata enters the physiological maturity stage, and high yield can only be obtained after drought with sufficient water and water supplement 15 days. Water supplement is carried out after the ground temperature drops at sunset.

Water should be controlled in September to prevent Armillaria mellea from growing too fast and digesting Gastrodia elata into empty shells and reducing production. 65438 10 to the end of April of the following year, digging and sowing can be carried out at any time. 1 m2 Gastrodia elata generally harvests 7 kilograms of fresh Gastrodia elata and processes 2 kilograms of dried Gastrodia elata. According to the market value of 520 yuan, 380 yuan 1 kg and 760 yuan. At the same time, 2 kilograms of first-generation cannabis seeds can be harvested, which is worth 240 yuan. In the second year, it can be used to expand planting by 3-4 square meters and harvest 6-8 kilograms of dry hemp. In the third year, it will be tripled, and the benefits will be calculated by yourself.

Because gastrodia elata is a variety that degrades year by year, it must be changed after two to three years of planting to ensure high yield and high efficiency.
