Gastrodia elata asexual reproduction high-yield technology

Abstract

The invention discloses a gastrodia elata asexual reproduction high-yield technology. The invention relates to the field of agricultural cultivation, and especially relates to a gastrodia elata cultivation method. With the technology, gastrodia elata yield can be increased, and gastrodia elata complete efficacy can be maintained. The gastrodia elata asexual reproduction high-yield technology comprises the following steps: 1, a seedling raising field is selected, wherein a field with moist, breathable and loose loam or sandy loam with good water permeability and rich humus is selected; 2, a fungus bed is cultivated, wherein a honey mushroom fungus material or fungus bed should be well cultivated before gastrodia elata cultivation; 3, seed treatment is carried out, wherein (1) gastrodia elata dug in the current year is adopted; (2) seed dressing is carried out with a 1:10-50 solution of a novel higher fatty acid film powder; and 4, after gastrodia elata planting, no fertilization, soil loosening or weeding is needed, and a wild status is maintained; soil water content should be often kept at approximately 40%, and a ground temperature should be kept at 15-28 DEG C.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a cultivation method of Gastrodia elata. Background technique [0002] Gastrodia elata, also known as Chijian, is a perennial herb of the genus Gastrodia elata in the family Orchidaceae. The rhizome is thick, without green leaves, and the capsule is obovate-elliptic, often propagated by tubers or seeds. Its rhizome is used in medicine to treat dizziness, numbness of limbs, convulsions in children and other diseases. It is a valuable traditional Chinese medicine. Gastrodia elata is mainly propagated by tubers, or can be propagated by seeds. However, the seeds have no endosperm, and the embryos are undifferentiated, so they cannot provide a source of nutrition for germination. Under natural conditions, in addition to the conditions required by ordinary green plants, seed germination also requires the participation of fungi. [0003] In the 1980s and 19...

Problems solved by technology

Because some breeders do not know or only have some superficial knowledge of genetics, blind breeding, coupled with breeding without selection, the result is that some of the species bred are self-pollination or inbreeding, which have extremely poor disease resistance, weak fecundity and low yield ; Although some species are hybrids, but the parents are not properly selected, the hybrid vigor is not obvious, and without repeated screening, the species is blindly expanded, and the genetic traits are unstable

The result is: some yield is not high; some medicine effect is not good;

In short, there are many kinds of species, the germplasm is different, uneven, and the income of the cultivators is low, so it is difficult to stabilize and high-yield
