Method of adopting biological bacteria for disposing continuous cropping obstacles

Abstract

The invention discloses a method of adopting biological bacteria for disposing continuous cropping obstacles. The method includes the following steps of preparing materials, wherein alfalfa meal, sesbania gum, compound amino acid powder, charcoal dust, trichoderma bacteria and bacillus thuringiensis are adopted as raw materials; carrying out fermentation treatment on the alfalfa meal, the sesbaniagum and the compound amino acid powder for 23-28 days, and then scattering the mixture into a field; mixing a trichoderma bacterium diluent with a bacillus thuringiensis diluent, then spraying the mixed liquid onto the soil surface, and meanwhile adjusting land for entering a fallow period. According to the method, the trichoderma bacteria serve as the main raw material of biological bacteria, the organisms causing continuous cropping obstacles on vegetables can be effectively disposed, the soil PH value during the continuous cropping and planting period of the vegetables can be effectively adjusted, the microbial flora structure of soil is maintained, the soil enzyme activity is improved, the proliferation of harmful fungi is restrained, the occurrence of diseases, pests and weeds is reduced, and a positive promotion function is achieved on increasement of the continuous cropping vegetable yield and settlement of the problems that soil nutrients are not balanced and diseases and pests still remain in the soil during continuous cropping.

Description

technical field [0001] The invention relates to the field of microbial bacteria, in particular to a method for treating continuous cropping obstacles by biological bacteria. Background technique [0002] Vegetables and other plant species are important economic crops in my country, but the yield of vegetables in our country is low, mostly due to continuous cropping for many years and large amount of fertilizer application, resulting in single consumption of nutrients in cultivated land, deterioration of land physical and chemical properties, soil nutritional imbalance, acidification, and aggravation of pests and diseases. , the content of soil microorganisms decreases, and poor growth and development of plants often occur, such as withered seedlings, rotten roots, abnormal growth points, inability to elongate new branches and leaves, and simultaneous occurrence of various diseases, which seriously restrict the production and development of vegetable and other plant varieties i...
