Good-quality and high-yield cultivation method of radix puerariae

Abstract

The invention discloses a good-quality and high-yield cultivation method of radix puerariae. The cultivation method comprises the steps of (1) seed selection and seedling growing, namely selecting a high-yield, less-crude fiber and high-starch variety and growing seedlings on a seed bed, (2) selection and preparation of land, namely selecting a sandy loam land relatively in soil layer and smooth in drainage for planting, (3) transplanting to land, namely sufficiently watering the seed bed before transplanting so as to facilitate lifting of seedlings with soil, planting the seedlings or chopped seedlings into the soil by an inclination angle of 30-40 degrees to the ground surface, 500-700 seedlings per mu at the row spacing of 80-100cm, compacting the soil after transplanting and injecting root colonization water, (4) fertilization, namely, appropriately applying diluted human or animal liquid dung once or twice after the seedlings are transplanted, AND when the seedlings grow by 25cm, spraying 0.3%-0.5% urea water every 15 days, and (5) field management, including rack erection, root sun drying and bud control. The good-quality and high-yield cultivation method of the radix puerariae has the advantages of realizing high production and high yield of the radix puerariae and increasing the content of the puerariae powder in the radix puerariae.

Description

technical field [0001] The invention relates to the field of planting medicinal plants, in particular to a high-quality and high-yield cultivation method of kudzu root. Background technique [0002] Pueraria, also known as kudzu, is a leguminous fabric of the genus Pueraria. Pueraria is rich in starch, isoflavones, and more than ten kinds of trace elements necessary for the human body, such as calcium, selenium, iron, copper, phosphorus, and potassium. It is an emerging green health-care and longevity food with the functions of "no hunger after breaking the grain, relieving the appearance and reducing fever, promoting body fluid and quenching thirst, appetizing and eating, curing hemorrhoids, and preventing cancer". The whole body of kudzu root is full of treasures. The stem bark fiber can be twisted, weaved kudzu cloth, and can also be used as papermaking raw materials. The leaves are excellent green fodder, which can be fed to pigs and rabbits. It can be processed into he...
