Wild-imitating gastrodia elata f. glauca and gastrodia elata f. elata cultivation method

Abstract

The invention discloses a wild-imitating gastrodia elata f. glauca and gastrodia elata f. elata cultivation method. The method comprises the steps as follows: (1) cross breeding: A selecting seeds; B cultivating gastrodia elata f. elata at the natural temperature, cultivating gastrodia elata f. glauca in a temperature-control chamber, and controlling the temperature at 25-28 DEG C 5-25 days before flowering of the gastrodia elata f. glauca; C performing topping 10 days before racemes of gastrodia elata grow to top ends; D after the gastrodia elata f. glauca and gastrodia elata f. elata flower simultaneously, performing reciprocal interchange artificial pollination; E picking capsules during cracking, uniformly mixing the powdery capsules with germinating strains; (2) bacterium bed preparation; (3) seed gastrodia elata dibbling; (4) harvesting. The gastrodia elata f. glauca and gastrodia elata f. elata hybridization rate is as high as 95% or above, a mild-imitating growth environment is created for growth of the gastrodia elata, and the first-generation strains have high activity, high reproductive capacity, high inoculation success rate, cannot be polluted by living contaminants easily, have heterosis, have high yield, can produce 750 kg of gastrodia elata f. glauca and gastrodia elata f. elata per mu on average and have high medicinal value and high disease resistance.

Description

technical field [0001] The invention belongs to the field of gastrodia elata cultivation methods, and in particular relates to a cultivation method imitating wild black-red gastrodia elata. Background technique [0002] Gastrodia elata (scientific name: Gastrodia elata BL.) is a perennial herb of the genus Gastrodia elata in the family Orchidaceae. It is rich in gastrodin, vanillin, protein, amino acids and trace elements. It is distributed in most parts of the country. To give nutrients, there is no need to absorb nutrients from the soil, and the soil only plays the role of matrix fixation. Gastrodia elata rhizomes are thick, without green leaves, and the capsules are obovate and oval. They are often propagated by tubers or seeds. The medicinal effect is better. [0003] In my country, Gastrodia elata has four varieties: black gastrodia elata, red gastrodia elata, yellow gastrodia elata and green gastrodia elata. Gastrodia elata has good medicinal effects, but the yield ...
