Gastrodia elata roll stick sowing

The sowing technology of Gastrodia elata rolls is a pioneering work of Wang Minghui, Chief of Agricultural Section of the Western Mountain Construction Committee of the people's Government of Chencang District, Baoji City, Shaanxi Province. Gastrodia elata roll sowing technology can greatly improve the germination survival rate of Gastrodia elata seeds, and greatly improve the yield and quality of Gastrodia elata, and its economic benefit is more than twice that of the traditional Gastrodia elata sowing method.

The traditional sowing method of Gastrodia elata sowed Gastrodia elata. After Gastrodia elata seeds germinated, more than 60% of the germinated seeds gradually aged and starved to death because they could not establish a parasitic feeding relationship with Armillaria mellea in time. The rolling rod sowing technology of Gastrodia elata can make the seeds of Gastrodia elata closely around the stick, and the fungal cord of Armillaria mellea spreads and grows everywhere in the leaves around the stick, which can be closely combined with each germinated seed to establish a parasitic feeding relationship, which can improve the survival rate of Gastrodia elata seeds and improve the yield and quality of Gastrodia elata. When the 0-generation Gastrodia elata is harvested, it is only necessary to take out the whole roll stick, uncover the bacterial stick, take out the small white and medium white Gastrodia elata as the 0-generation Gastrodia elata, and the rest of the millet is still closely connected with the fungal cord of Armillaria mellea. Reroll it and cultivate it again. Because it did not destroy its parasitic feeding relationship, the growth of rice hemp can be restored quickly. There is no loss, but also avoid the traditional sowing Gastrodia elata in the harvest of Gastrodia elata, because the volume of rice is too small, often because it can not be picked out and cause heavy losses.

Armillaria mellea was cultured in August every year, and Gastrodia elata was sown from May to June of the following year. Each square meter needs to prepare 18 hard fresh sticks (about 30kg) of broad-leaved trees with a diameter of 3cm~8cm and 50cm~60cm, cut a fish scale mouth every 7cm~10cm, cut 1-3 sides, medium-coarse-grained non-polluting sand 0.25cm3, sand 6 hours before use, it is best to wash it with water, broad-leaved trees deciduous 2 kg. Need to wash in clean water for 4 to 6 hours, drain water and set aside. The sunshade net of 50cm × 40cm is 18. 2 bottles of germinating bacteria (500 grams per bottle) and 18 capsules of Gastrodia elata.

The sowing time of Gastrodia elata is usually from May to June, when the capsule of Gastrodia elata is mature one after another. When sowing, first tear the germinating bacteria into pieces and put them in a clean basin. Take 18 capsules of Gastrodia elata, pinch and mix into the germinating bacteria (can sow 1m2), stir evenly. Take a sunshade net, lay it flat on the ground, sprinkle a layer of wet broad-leaved tree leaves, sprinkle a layer of germinating bacteria mixed with Gastrodia elata seeds (a bottle of germinating bacteria can roll 9 sticks), remove a cultivated stick covered with Armillaria mellea, place it flat on one end of the sunshade net, grab the sunshade net with both hands, and roll it together with leaves, germinating bacteria and Gastrodia elata species. Then spread 5cm thick on the ground where you are going to sow Gastrodia elata, and then put a roll stick at intervals of 5cm. Cover sand 5cm thick beat flat, if sowing Gastrodia elata in dry areas with little rain all the year round, it is better to cover the sand with a layer of wet leaves or wheat and straw.

After sowing Gastrodia elata, 1 ∶ 1000 times potassium permanganate solution was sprayed evenly on the sowing border of Gastrodia elata, and the surface was disinfected and sterilized. After 25 days, water properly according to the drought condition, keep the border surface moist, and avoid flooding. When the temperature exceeds 27 ℃, set up a shade, spray cold water into the air at noon to cool down, in case of continuous rain, cover the shade with plastic film to cover the rain. Dig drains to drain waterlogging, and strictly prevent human and animal trampling.

When the temperature drops below 10 ℃, in Shandong and Shaanxi, it is usually the end of October and the beginning of November, or in March of the following year. In short, during the dormant period of Gastrodia elata, the 0-generation species of Gastrodia elata must be harvested, transplanted or transplanted. When harvesting, first remove the leaves from the border, gently pick off the sand, then grab both ends of the roll stick with both hands, gently remove the leaves and sunshade net from the fungus stick, and collect white hemp for planting or selling. Roll up the remaining rice hemp, together with the sunshade net and leaves, and cultivate it for another year. If there is too much rice hemp in the original roll stick, it can also be taken out together with the leaves and rice hemp, or cultivated with a separate roll stick.
