Seedling raising method of polygonum

Abstract

The invention discloses a seedling raising method of polygonum. The method comprises the following steps of: selecting six-month or annual branches of robust, disease-free and pest-free mother plants as cuttings; cutting into small pieces, and carrying cutting treatment; selecting flat-terrain, loose, fertile, conveniently-irrigated and well-drained sandy loam or loam as a cuttings bed, and plowing the soil and applying a basic fertilizer in a month before cutting; ditching; disinfecting a seedbed; cutting; tightly inserting the treated cuttings in the surface of a ditch according to the plant and row spacing of 3cm * 8cm, with buds up, and the lower end buried into the soil, irrigating normal root water thoroughly; top dressing; topping when cutting seedlings germinate sprouts about 10cm long, keeping the height of the seedling about 20cm, and the length of the sprouts 15cm; transplanting when the seedlings are raised about 40 days in spring or about 60 days in autumn; and firstly irrigating the seedbed thoroughly on the day before lifting. The seedling raising time is short, the survival rate is high, and the yield is stable.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a method for raising seedlings of Polygonum multiflorum. [0002] Background technique [0003] Polygonum multiflorum is a perennial twining vine of Polygonaceae. The root is slender, and the end becomes a hypertrophic root tuber, and the appearance is reddish brown to dark brown. The roots, vines and leaves of the plant are all available for medicinal purposes. The Chinese medicine names are: Polygonum multiflorum, Yejiaoteng and Polygonum multiflorum leaves. The traditional Chinese medicine Polygonum Polygoni Multiflori can be divided into Radix Polygoni Radix Radix Radix Raw and Radix Polygoni Radix Radix Radix Radix Radix Radix Radix Radix Radix Radix Radix Radix Radix Radix Radix Radix Radix Raw Radix Radix Radix Raw and Radix Radix Radix Radix Raw Radix Radix Raw Radix, and Radix Radix Radix Radix Radix Radix Raw. [0004] The commonly used seedling raising method: the ...

AI Technical Summary

Problems solved by technology

[0005] The main problems are as follows: one is that the seedbed is not disinfected with soil, which is easy to cause bacterial infection, and the survival rate of seedlings is low; the other is that the cuttings are not well selected and disinfected, the bacterial infection is serious, the stability is poor, and the seedling rate is low

The third is that the cuttings are not soaked in biogas slurry, the root system of the cuttings grows slowly, and the growth is relatively poor

Fourth, the standard design of seedbeds has not been established, which is not convenient for field seedling management

Fifth, the topping and pruning treatment is not carried out, and the buds germinate less, which affects the yield of Polygonum multiflorum.
