A kind of method for promoting the growth of ratoon sugarcane root system after machine harvesting

Abstract

The invention relates to the technical field of sugarcane planting, and specifically discloses a method for promoting the growth of the root system of ratoon sugarcane after machine harvesting. 6~8cm, spray conditioner, described conditioner is made up of following components by weight: 1~3 parts of matrine, 3~5 parts of fulvic acid, 2~3 parts of wood vinegar, 500 parts of water , the conditioner is diluted 400-500 times with water for spraying, the dosage of conditioner per mu is 100-120ml, and it is dried for 3-5 days after spraying; for fertilization, decomposed organic fertilizer and improver are applied as base fertilizer to both sides of the sugarcane, The modifier is a modified zeolite loaded with indolebutyric acid. The method of the invention can promote the growth of the root system of the ratoon sugarcane, reduce the risk of sugarcane infection and disease, improve the survival rate, improve the stress resistance of the ratoon sugarcane, promote the germination of the ratoon sugarcane, improve the growth rate and the tillering rate of the ratoon sugarcane, and increase the yield of the sugarcane. It can improve soil permeability after machine harvesting and improve soil water and fertilizer retention performance.

Description

technical field [0001] The invention belongs to the technical field of sugarcane planting, in particular to a method for promoting the growth of the root system of ratoon sugarcane after mechanical harvesting. Background technique [0002] Rumpling sugarcane refers to the sugarcane buds at the base of the sugarcane pocket left in the ground after the previous season of sugarcane is harvested, and germinates into new plants under appropriate water, air and heat conditions. Routine sugarcane has obvious advantages of saving seeds, saving labor, early maturity, facilitating labor arrangement and reducing production costs. As an important cultivation system for sugarcane production and development, ratoon sugarcane cultivation is widely used at home and abroad. [0003] The sugarcane industry is one of the important economic pillar industries in Guangxi. The most important link in the sugarcane industry is the production of sugarcane. The entire production process of sugarcane i...

[0003] The sugar cane industry is one of the important economic pillar industries in Guangxi. The most important link in the sugar cane industry is the production of sugarcane. The whole production process of sugarcane includes land preparation, planting, breaking ridges, fertilization, soil cultivation, harvesting, etc., and the sugarcane harvest is sugarcane The most cumbersome link in the production process, most of which rely on manual harvesting at present, has defects such as low production efficiency, high labor costs, and low industrial benefits, which seriously hinder the development of the sugar industry

Realizing the mechanized harvesting of sugarcane is the fundamental way out for the sustainable development of the sugarcane industry in Guangxi. However, due to mechanical harvesting and rolling, cane husks will be damaged, which will cause cane husks to be easily infected with diseases and reduce the survival rate. The deterioration of the soil environment in the field is mainly manifested in the decrease of soil porosity, the increase of bulk density, the decrease of soil air permeability and water permeability, the change of the number of animals and microbial activities in the soil, and the distribution and diffusion of N, P, K and other elements are affected. Restriction, soil fertilizer use efficiency decreases, affecting the growth and development of ratoon cane; inhibiting root activity, resulting in weak growth of the aboveground and root system of sugarcane in the early stage, affecting the emergence, germination and normal growth and development of ratoon cane, and having a negative effect on the yield of sugarcane in the later stage, etc. One of the bottlenecks in the promotion of production mechanization
