Problems solved by technology

Due to the continuous asexual reproduction of rice hemp and white hemp, the species degeneration is obvious (the hemp body becomes longer and thinner), and the secondary inoculation is caused by two times of overturning, not only it takes about 20 days each time to plant hemp without nutrition. growth, and

Embodiment 1

[0033] Select sargassum with a single body weighing more than 150g, full and well-developed terminal buds, and a body shape with an aspect ratio of 3:2. Artificially increase the ground temperature indoors in early March. The ground temperature is controlled at 15°C and the air humidity is controlled at 80%. , Cultivate arrowroot for bolting and flowering, artificially assisted pollination after 23 days, adjust the flowering period of different parents to be consistent, and carry out cross-pollination, remove both ends of the inflorescence when pollinating, remove 2 flowers from the lower part, and remove 3 flowers from the upper part to ensure the same maturity of the capsules , 20 days after pollination, the produced capsules begin to soften, the seeds mature in early and mid-April, and the powdery seeds are picked when the flesh turns red;

Abstract

The invention discloses a technical method for culturing gastrodia elata at one time under forest, which comprises gastrodia elata seed production technology, land selection and preparation technology, seed treatment technology, seeding technology, nutrient regulation and management technology and gastrodia elata harvest method. The method has the advantages of capacity of not struggling for land with crops, short production cycle, manual labor and bacteria conservation, capacity of avoiding variety degeneration and effectively preventing large head and small tail of the gastrodia elata body, and obvious ecological benefit, economic benefit and social benefit.

Description

field of invention [0001] The invention relates to a technical method for cultivating Chinese medicinal materials, in particular to a technical method for cultivating next-time hemp of Gastrodia elata. Background technique [0002] The artificial conventional cultivation method of Gastrodia elata is completed in three steps. The first step is to cultivate arrowroot for bolting and flowering, obtain capsules through artificial assisted pollination (generally carried out in April to June), and mix the mature seeds with germination bacteria and Armillaria. The material is accompanied by planting (the time of planting is usually June), and the germination and formation of rice hemp (the first-class species, in November of the year); Monthly expansion), in October of the second year, white hemp (secondary seed hemp, also called cultivated species) can be formed, and the third step is to use white hemp as seed in October to November of the second year, and add new ones with Armill...
