Embodiment Construction

[0015] 1. Land selection and soil preparation: For cultivating Polygonum cuspidatum, it is necessary to choose an environment with warm climate, good rainfall or convenient irrigation. It is better to choose a thicker, loose and fertile loam soil. Plow the land deeply (25-35cm) once and level it. , rake fine.

[0016] 2. Propagation of stems and branches: before the flowering of Polygonum cuspidatum in May-June, select healthy and disease-free stems and branches, cut them at the forks to make the branches straight, and open a 5-8cm deep ditch in loose soil or sand. The row spacing is 10cm, one stem branch is placed horizontally, and the soil is compacted. Keep the soil surface moist until the germination is complete before watering less or not.

[0017] 3. Transplanting and planting: When the branches grow roots and sprout, cut them into small sections from the budding nodes of the branches. Each section is a planting seedling. There must be buds and roots formed on each sect...

Abstract

The invention discloses a method for cultivating giant knotweed rhizome, which comprises the following steps: firstly, choosing and grading land, choosing the loose and rich soil with thick soil layer, grading and harrowing carefully; secondly, breeding with stalk and branch, shearing the stalk and branch in the divaricating place, put the stalk and branch laterally in the supersulcus, burying and consolidating; thirdly, replanting for planting, when the branch rooting and budding, shearing the branch into small branch in the budding joint, planting each small branch; fourthly, field care, clean tillage, additional manuring and watering; fifthly, recovering and storing, doing recovering two years later, storing after handling the root and stalk. The process of the invention is simple, employing the stalk and branch as the breeding material, embedding the stalk and branch directly, and the survival rate is above 98%.

Description

technical field [0001] The invention relates to the field of propagation of Chinese medicinal material Polygonum cuspidatum wild-transplanted species, and more particularly relates to a cultivation method of Polygonum cuspidatum. Background technique [0002] Polygonum Cuspidatum Sieb.et Zucc is a perennial herb or subshrub of Polygonaceae, also known as spotted root, spotted stick, and Zijinlong. It often grows in hillside grasslands, ditch sides, roadsides, and wet places under forests below an altitude of 1400m. It is mainly distributed in various places south of the Yangtze River in my country and in Shaanxi, Hubei, Sichuan and other provinces. The rhizome of Polygonum cuspidatum is rich in polydatin, resveratrol, emodin, chrysophanol, rhein, etc. Its extracts are widely used in various industries such as medicine, health products, and cosmetics, and the international market demand is huge. At present, the medicinal materials of Polygonum ...
