Method for rapidly breeding kudzu vine root seedling by separating rhizome

Abstract

The invention discloses a method for rapidly breeding kudzu vine root seedlings by separating rhizomes. The method comprises: in a kudzu vine root field in which transplanted kudzu vine roots survive, cutting off multi-stem plants which grow from the rhizome of a kudzu vine root seedling and grow normally and vigorously along the rhizome with epidermis, soaking the roots of the plant in a breeding solution which is prepared in advance, and then separately planting the plants which are cut from the rhizomes in prepared nutrition cups or nutrition land blocks, after roots of the plants grow new roots, transplanting the seedlings with soil to seedling missing positions, or replacing the seedlings which are bad in growth vigour. The method is very easy to master and apply, and the supplemented kudzu vine root seedlings are sister seedlings of originally planted plants. The kudzu vine root seedlings are easy to survive, roots are developed and complete, and yield has no distinction with original plants. The method is suitable for filling the gaps with seedlings when seedling supplementing is needed or seedlings are missed by accidents in field planting. The method is simple in technology, fast in breeding speed, low in device investment, low in cost, and easy in popularization.

Description

technical field [0001] The invention belongs to the technical field of seedling breeding of traditional Chinese medicinal materials, and in particular relates to a rapid breeding method of kudzu root divisions. Background technique [0002] Pueraria lobata is a perennial vine belonging to the legume family. The roots of Pueraria lobata are rich in starch and can be made into dozens of exquisite foods. Puerarin contains puerarin, isoflavones, essential amino acids, multivitamins, and more than ten kinds of trace elements necessary for human body, such as calcium, selenium, zinc, iron, manganese, germanium, etc. It has the functions of skin care, removing garbage in the body, etc., and has special curative effects on coronary heart disease, angina pectoris, diabetes, etc. Because its efficacy can be compared with that of American ginseng, famous Chinese medicine experts call it the "gold" of medicinal and edible plants, so it is called "golden kudzu". The Ministry of Health h...

Problems solved by technology

At present, the planting area of ​​kudzu root in my country is less than 3 million mu, and the market gap is very large.

[0003] At present, there are traditional cutting, layering and tissue culture methods for the propagation of Pueraria lobata. Most of the large-scale planting adopts the method of cutting seedlings. After the Pueraria seedlings are transplanted, often due to weather reasons or poor management, resulting in lack of nests and broken seedlings. The patched seedlings often germinate later, and their growth generally cannot keep up with the previous batch of seedlings. Sometimes there are even no patched seedlings at all. The empty nests can cause a yield loss of 2.5 to 5 kg of kudzu root per plant, which affects the yield. great influence
