Wild buckwheat seedling breeding method

Abstract

The invention provides a wild buckwheat seedling breeding method. The wild buckwheat seedling breeding method comprises the following steps of (1) selecting wild buckwheat stalks to prepare cutting stalks; (2) soaking one ends of the cutting stalks in a rooting agent for a certain period of time, and then taking out the cutting stalks; (3) inserting one ends of the cutting stalks soaked with the rooting agent into a cutting garden; and (4) after cutting is completed, arranging a sun-shading part above the cutting garden, and breeding wild buckwheat seedlings. Seedlings bred by the wild buckwheat seedling breeding method provided by the invention have the advantages that the transplanting survival rate is up to 96 percent, and the growth condition is good. Meanwhile, the wild buckwheat seedlings bred through the breeding method can avoid the problems that the provenance degradation rate of seedlings produced through tuberous root breeding is high, the infection rate is high in the subsequent growth process, the provenance tuberous root breeding coefficient is low, and the use amount of tuberous root seedlings is large.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a method for breeding golden buckwheat seedlings. Background technique [0002] Golden buckwheat (Fagopyrum dibotrys (D.Don) Hara) is a perennial herb of the Polygonaceae buckwheat genus. Its dried roots are used as medicine. , peritonsillar abscess and other diseases; modern studies have found that golden buckwheat root has anti-cancer, inhibits lung invasion and metastasis of tumor cells, eliminates phlegm and anti-inflammatory and inhibits platelet aggregation, reduces reduction reaction and enhances phagocytosis of macrophages . Golden buckwheat has a wide distribution and large genetic differences. Due to a large number of excavations, it is almost on the verge of extinction. In 1999, it was included in the first batch of "National Key Protected Wild Plant List" and is a Class II protected plant. At present, in addition to being used in the formula of decoction p...

Problems solved by technology

[0003] Golden buckwheat can be propagated by sexual reproduction (seed propagation) and asexual reproduction. Sexual reproduction (seed reproduction) has the advantages of high provenance stability and high survival rate. However, since golden buckwheat is an infinite inflorescence, Seed shattering is strong, the maturity time of seeds in the same inflorescence is inconsistent, it is difficult to collect seeds, and the seed yield is low, the cost of seed breeding and production of seedlings is high, and it is difficult to realize large-scale seedling production

Therefore, currently the main propagation method of golden buckwheat is to divide the root tubers to produce seedlings. At present, the main sources of root tubers are wild digging. The wild resources of golden buckwheat are destroyed, and the seedlings produced by root tuber division have a high provenance degradation rate. The root rot of golden buckwheat cultivated by tuber seedlings is very serious after two years, and the disease rate will be higher in the subsequent growth process. , Provenance root tuber reproduction coefficient is low, the amount of tuber seedlings used is large, etc., which have certain limitations on the development of the golden buckwheat industry, and have certain destructive effects on wild resources
