Problems solved by technology

However, when adopting the above-mentioned bagged breeding method, it is necessary to cover the soil outside the cultivation bag. Because the soil is thicker, the soil temperature of the germination layer of Gastrodia elata will not rise, and Gastrodia elata is perishable, resulting in low germination rate and low yield of Gastrodia elata. At the same time, Gastrodia elata is cultivated. And the labor cost of harvesting Gastrodia elata is higher

Embodiment 1

[0022] During the Gastrodia elata harvesting period, choose the local original species of arrow hemp as the seed hemp, which requires complete individual development, robustness, full terminal buds, no damage, and a single weight of more than 100g; plant the selected hemp seeds in soil moisture or flowerpots In China, after the seed hemp blooms, artificially pollinate it, try to use different plants for cross-pollination, and harvest the mature fruit after about 20 days of pollination. Stir the mushrooms evenly, put them into a plastic bag, and put them into the cultivation room for 72 hours. The temperature of the cultivation room is controlled at 18°C~20°C, the humidity is 70%~80%, and it is protected from light and kept ventilated; The matrix is ​​mixed fir sawdust and mud-free sand and then sprayed with water to moisten, wherein the volume ratio of fir sawdust to mud-free sand is 2:1; Plant small Osmanthus osmanthus; choose fungi with a length of 15cm, cut three rows of fi...

Embodiment 2

[0024] During the Gastrodia elata harvesting period, choose the local original species of arrow hemp as the seed hemp, which requires complete individual development, robustness, full terminal buds, no damage, and a single weight of more than 100g; plant the selected hemp seeds in soil moisture or flowerpots In China, after the seedlings bloom, artificially pollinate them, and try to use different plants for cross-pollination. After about 20 days of pollination, harvest the mature fruits. After harvesting, take 6 fruits and a pack of 0.5kg dendrobium mushrooms Stir evenly, put into a plastic bag, and put it into a culture room for 72 hours. The temperature of the culture room is controlled at 18°C~20°C, the humidity is 70%~80%, and it is protected from light and kept ventilated; Substrate, the substrate is Chinese fir sawdust and mud-free sand mixed well and then sprayed with water to moisten, wherein the volume ratio of Chinese fir sawdust and mud-free sand is 2:1; a layer of ...

Abstract

The invention discloses a breeding method for gastrodia elata. After cunninghamia lanceolata sawdust and shale-free sand are uniformly stirred, the stirred substance is sprayed with water to be wet and the wet substance replaces sandy soil as a substrate, so that the weight of each breeding bag filled with gastrodia elata seeds is reduced from 15-20kg to 7-8kg, the labor intensity is reduced, and the cost input is reduced; when the breeding bags are placed under shading woods, no covering is needed, the management is facilitated, and the yield is stable; the yield of the gastrodia elata is increased from about 0.2kg of each bag on average in the past to over 0.8kg of each bag, and planting benefits are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of gastrodia elata breeding, in particular to a gastrodia elata breeding method with high germination rate, high yield and strong adaptability. Background technique [0002] Gastrodia elata, also known as Chijian, is a perennial herb of the genus Gastrodia genus in the family Orchidaceae, with thick rhizomes, no green leaves, obovate oval capsules, often propagated by tubers or seeds, and its rhizomes are used as medicine to treat dizziness and numbness of limbs , convulsions in children and other diseases, it is a valuable traditional Chinese medicine. [0003] Due to the high medicinal value of gastrodia elata and the huge market demand, gastrodia elata has been in short supply. Since the seventies of the 20th century, there have been many researches on the breeding and breeding technology of Gastrodia elata, but the development of Gastrodia elata planting industry has been hindered due to the immature cu...
