Problems solved by technology

[0003] The main reason for soil continuous cropping obstacles is that after some nematodes and pathogenic microorganisms targeting a certain crop multiply in large numbers, if the same plant continues to be planted in the soil, the root system will not grow normally and affect the growth and development of the plant, resulting in crop yield reduction or even die
The existing continuous cropping obstacle prevention and control technology can not fundamentally solve the impact of continuous cropping obstacle on crops

Abstract

The invention relates to the technical field of planting, in particular to a method for overcoming continuous cropping obstacles. By applying quick lime and injecting liquid ammonia, the purpose of killing nematodes and other pathogenic microorganisms is achieved. According to the method, root-knot nematodes in vegetable planting can be effectively prevented and controlled, the growth and reproduction of pathogenic bacteria in soil can be inhibited, and the method has the advantages of increasing the soil fertility, promoting the growth of root stocks, reducing the use of chemical fertilizers,and improving the yield and quality of crops.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a method for improving continuous cropping obstacles. Background technique [0002] Continuous cropping obstacle, also known as cropping disease, replanting disease, and ground avoidance phenomenon, refers to that when the same crop or related crops are continuously cultivated in the same soil, even under normal cultivation and management conditions, the growth potential will become weak, and the yield and A phenomenon of quality degradation. The continuous cropping phenomenon is common all over the world, and it is widely distributed in Japan, China, India and other places in Asia, and the most serious ones are mainly cereals and vegetables. [0003] The main reason for soil continuous cropping obstacles is that after some nematodes and pathogenic microorganisms targeting a certain crop multiply in large numbers, if the same plant continues to be planted in the soil, the root ...
