A kind of kudzu root layering propagation method

Abstract

The invention discloses a radix puerariae layering propagation method and belongs to the technical field of radix puerariae propagation. The radix puerariae layering propagation method includes: step one, paving a layer of geotechnical cloth in a layering groove, and filling the layering groove with nutrient soil; step two, selecting strong radix puerariae with 2-3 internodes of caulis puerariaes, placing the nodes of the radix puerariae in the layering groove, burying the nodes with the nutrient soil, enabling the nodes of the caulis puerariaes to be buried in the nutrient soil, and watering with root fixing water after burying; step three, transplanting the radix puerariae after the buried nodes of the caulis puerariaes root. The radix puerariae layering propagation method has the advantages that according to growing growth habit of the radix puerariae, the nutrient soil suitable for growth of the radix puerariae is provided, by arrangement of the layering groove, the nutrient soil is separated from outside soil, cross infection of bacteria in the nutrient soil and the outside soil can be avoided, by the aid of the nutrient soil, quick rooting, quick sprouting and root system expanding of the nodes of the caulis puerariaes can be guaranteed, and after root fixation, radix puerariae seedlings can be transplanted quickly by the aid of the geotechnical clothes.

Description

technical field [0001] The invention belongs to the technical field of kudzu root propagation, in particular to a kudzu root layering propagation method. Background technique [0002] Pueraria lobata is a perennial herbaceous deciduous vine climbing plant of the leguminous family. It likes a warm and humid climate. It grows in areas below 2,500 m above sea level, mostly between 1,600 and 2,100 m above sea level. It grows on cool and humid slopes with a relative humidity of more than 60%, but it is also resistant to cold, drought, and waterlogging. Pueraria is a fast-growing, high-quality, high-yield plant with a starch content of 20% to 28% and a puerarin content of 1.5% to 2.3%. The yield per mu of two-year-old Pueraria generally reaches 5000 to 8000kg. In the Ming Dynasty, Li Shizhen compiled the classic book of Chinese pharmacy "Compendium of Materia Medica", which records that Pueraria lobata was used as medicine, and Zhang Zhongjing, a medical sage in Ming Dynasty, use...

AI Technical Summary

Problems solved by technology

1. Due to the uneven nutrient composition of the layered soil, the pueraria seedlings grow weakly; at the same time, the pueraria layered in different soils, due to the large difference in nutrient components, the growth of the pueraria seedlings grown by the layered propagation varies greatly, which is not conducive to the same later stage. transplant

2. When transplanting kudzu root seedlings, manual excavation is easy to damage the kudzu root seedlings and reduce their survival rate; when digging, soil is needed to wrap the roots of the kudzu root seedlings, and the workload is heavy

3. Since the pueraria seedlings need to be transplanted to different places, the bacteria carried in the soil covering the pueraria seedlings are likely to pollute the soil of the planting place

4. When the kudzu root seedlings are transplanted every other year, the ground will be occupied, making it difficult to plow and perform other operations on the ground where kudzu root is planted. It is necessary to wait for the next year to perform related operations after transplanting
