Organic preparation and its application for disinfection of banana continuous cropping obstacle disease soil

Abstract

The invention relates to an organic agent for disinfecting banana continuous cropping obstacle diseased soil and usage, and the method comprises the steps of mixing dry plant powders like reed, potato vine, straw, wheat straw, pea straw, bagasse, bean dregs, broad bean straw and corn straw with molasses, wherein the weight percentage of the molasses is 0-100%, and the dry plant powder and the molasses are packaged respectively before being use in order. The usage method comprises the steps of digging out the root of banana ground with continuous cropping obstacles and removing the straw; spreading the dry plant powder or the molasses in a preset proportion uniformly on the ground and plowing the ground with a rotocultivator; burying the plant powder and the molasses in a soil cultivated horizon in a mixing way; watering uniformly the ground by 30-80 ton of water per Mu to keep the soil wet; covering the ground to isolate the soil from the air; controlling the soil temperature between 25-50 DEG C and an oxido reduction potential below 60mv; and removing the covered film after maintaining an anaerobic strong reduction state for 3-4 weeks. According to the method, continuous cropping obstacle of the banana ground can be effectively eliminated; and incidence of disease where insect disease is infected by banana soil is greatly reduced.

Description

technical field [0001] The invention relates to an agricultural technology, in particular to an organic preparation for disinfection of banana continuous cropping obstacle diseased soil and its application. Background technique [0002] Banana continuous cropping obstacle is a common phenomenon. After years of in-depth research, people have found out more about this phenomenon and the cause of this phenomenon. It is generally believed that the barriers to continuous cropping of bananas are mainly caused by multiple factors within the crop, soil, microorganisms and their environmental systems, the most important of which is the imbalance of microbial systems in the root zone. Hardening and aggravation of soil-borne diseases and insect pests lead to weakened growth of bananas, reduced disease resistance, reduced yield and quality, or even no harvest. [0003] In the prior art, the method to solve the obstacle of continuous cropping of bananas is mostly to carry out cyclic rot...

AI Technical Summary

Problems solved by technology

According to the survey, some banana orchards are still being planted after continuous cropping for more than 10 years. In order to obtain current benefits, the growers blindly use a large amount of chemical fertilizers and pesticides regardless of the performance of continuous cropping obstacles, which accelerates the speed of soil acidification and hardening, and the soil micro-ecological environment accelerated deterioration

[0006] Therefore, on the one hand, there is serious difficulty in popularizing existing technologies for eliminating obstacles to continuous cropping of bananas;
