A kind of rapid propagation method of pueraria seedlings

Abstract

The invention discloses a rapid breeding method of kudzu root seedlings by splitting. In the field of kudzu root seedlings that have been transplanted and survived, the multi-stem plants that grow normally and vigorously from the kudzu root are cut off along the kudzu root and the epidermis, and then Soak the roots of the plant in the pre-prepared propagation solution, and then plant the cut plants in the prepared nutrient cups or nutrient land plots. After the roots of the plants grow new roots, put the seedlings together with the soil Transplant to the seedling-deficient site, or replace the poorly growing seedlings. The method of the present invention is very easy to grasp and apply, and the supplemented kudzu seedlings are sister seedlings of the original plants, which are easy to survive, have well-developed and complete root systems, and have no difference in yield from the original plants; they are suitable for the production of supplementary seedlings when supplementary seedlings are needed or accidental lack of seedlings in field cultivation, The technique is simple, the reproduction speed is fast, the investment in equipment is small, the cost is low, and it is easy to popularize.

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
