Efficient cultivation method for improving soil acidity, precise fertilization and matched intercropping to comprehensively prevent and control banana wilt

Abstract

The invention discloses an efficient cultivation method for improving soil acidity, precise fertilization and matched intercropping to comprehensively prevent and control banana wilt. Soil pH is regulated through a soil testing formula, precise fertilization is performed according to soil fertility, main banana nutrition NPK absorption amount, the rate of absorption and utilization and target yield, meanwhile peanut intercropping is performed to conserve water and soil, nodule nitrogen fixation is beneficial to banana growth, the soil microbial diversity is improved, and the occurrence rate of the banana wilt is remarkably reduced. The cultivation method is simple and clear to operate, the soil pH and the diversity of organic matter, bacteria and actinomycetes are remarkably improved, the amount of soil fungi (phytopathogens) is decreased, and the banana wilt is decreased. In addition, the fertilizer usage amount is effectively decreased, the high peanut and banana yield is obtained. The efficient cultivation method has the positive significance on prevention and control of the banana wilt and chemical fertilizer decrease and replacement through land applying and maintaining biological measures and efficient cultivation mode and has the application values on remarkable improvement of banana productivity, economic benefits, environment protection of producing areas and sustainable development of banana production.

Description

technical field [0001] The invention relates to a cultivation method for preventing and controlling banana fusarium wilt. Background technique [0002] Banana (Musa nana L.) is a very healthy tropical fruit rich in antioxidants (vitamin A, vitamin B6, vitamin C, etc.) and mineral nutrients (potassium, nitrogen, phosphorus, calcium, magnesium, etc.). One of the important economic and food crops. Bananas are also one of the most valuable agricultural exports and are widely grown in suitable tropical regions around the world. There are 120 countries in the world that grow bananas, and the planting areas are mainly distributed in tropical and subtropical regions between north and south latitudes of 30°. The annual output of bananas in the world is nearly 100 million tons, and the total output value is only behind rice, wheat, and corn. China is one of the main producing countries of bananas in the world. Compared with other crops, bananas have higher economic benefits. [0...

Problems solved by technology

The use of a large amount of chemical pesticides and fungicides and the selection of disease-resistant varieties are the countermeasures for the prevention and control of banana wilt, but the effect of fungicides is not significant, and disease-resistant varieties are still being cultivated

[0008] Existing studies have shown that crop rotation and intercropping can effectively reduce the number of fungi in the soil and significantly increase the number of Bacillus and Pseudomonas in the soil that have the function of antagonizing the pathogenic bacteria of banana wilt. and the relationship between soil microorganisms and banana wilt disease, or to test the benefits of organic functional fertilizers in replanting bananas, without systematic soil testing and formulating to improve soil pH, precision fertilization and supporting inter-integrated control of banana fusarium wilt
