Gastrodia elata sexual propagation technology

Abstract

The invention belongs to agriculture planting, and in particular relates to a gastrodia elata cultivation technology which specifically comprises the following steps of: selecting gastrodia elata, covering the gastrodia elata by fine soil with adequate water, and putting the gastrodia elata at a constant temperature of 18-28 DEG C to grow until flower; pollinating after the maturation of pollen; after the maturation of fruits, picking seeds, and mixing the seeds with germination bacteria; sawing broad leaf tree twigs into 30-40 centimeters of small segments, chipping 4-6 scaly small holes on the small segments, and putting armillaria mellea into the scaly small holes to be used as bacteria; selecting sandy loam field with gradient, digging ridges, uniformly spreading the seeds over ridge bottoms, laying the bacteria in the ridges which is spread with the seeds, and laying 2-3 centimeters of fin soil over the bacteria; covering with sandy soil, and ridging for ranks; digging out the seeds in October of the next year to obtain poacynum pictum bail; during beginning of the winter to the fresh green of the next year, seeding the poacynum pictum bail according to step 5; and after the winter begins, picking the gastrodia elata. Compared with the conventional method, the cultivation period of the method is obviously shortened, and sufficient labor is provided for farmland; the cultivation process is simplified, and the probability of various crop failures is reduced; and the added additive is contributed to increasing the seed germination, and furthermore, the yield is increased.

Description

Technical field [0001] The invention belongs to agricultural planting, and particularly relates to Gastrodia elata planting technology. Background technique [0002] Gastrodia elata is an orchid plant with mycorrhizae. It has no roots, no green leaves, and cannot produce nutrients for its own growth. After the Gastrodia elata seeds germinate, they mainly rely on decomposing the Armillaria hyphae that invade the body to grow. The mature corm of Gastrodia elata is a valuable Chinese medicinal material, known as the "second ginseng". It has been a good medicine for treating diseases and maintaining health in our country in the past dynasties. It has been listed as a top-grade herb in the past two thousand years. Gastrodia elata has the effects of dispelling rheumatism, anticonvulsants, relieving dizziness, and lowering blood pressure, especially in analgesia and sedation, without side effects. At present, Gastrodia elata has been gradually used in health care, medical treatmen...

AI Technical Summary

Problems solved by technology

The reproductive coefficient of Gastrodia elata is low, and scientific and technological achievements have not been transformed into actual production on a large scale. Many hemp farmers are still using several generations of seeds, which are seriously degraded. The average yield per square meter is about 1kg, and the income is less than 30 yuan. The cycle is three years, and the average annual income per mu of land is less than 1,000 yuan, which affects the enthusiasm of farmers to plant Gastrodia elata and restricts the development of Gastrodia elata industry
