Abstract

The invention relates to a biofertilizer, particularly an insecticidal and antibacterial biofertilizer and a preparation method thereof. The invention enhances the bactericidal and insecticidal effects and fertilizer efficiency of the microbial fertilizer. The insecticidal and antibacterial biofertilizer is prepared from 30-50 parts of 550 million / ml Bacillus megaterium, 10-30 parts of 400 million / ml Rhodopseudomonas palustris, 1-3 parts of 562mg / mL Streptomyces avermitilis drug effect component B1a, 200-300 parts of molasses, 0.02-0.04 part of sodium dodecyl benzene sulfonate, 0.03-0.05 part of Tween-80 and 600-800 parts of water. The insecticide / fertilizer compound biological agent and the production technique thereof establish technical parameters of fermentation of Bacillus megaterium, Rhodopseudomonas palustris and Streptomyces avermitilis, and all the indexes satisfy the quality standard of microbial fertilizers of Department of Agriculture. The insecticide / fertilizer compound biological agent provided by the invention has insecticidal and antibacterial effects, and has wide application prospects.

Description

technical field [0001] The invention relates to a biological fertilizer, in particular to an insecticidal and antibacterial biological fertilizer and a preparation method thereof. Background technique [0002] Microbial fertilizers are fertilizers prepared from one or several living cells of beneficial microorganisms. There are mainly rhizobia agents, nitrogen-fixing bacteria agents, phosphorus bacteria agents, antibiotic agents, compound bacteria agents, etc. The production cost of microbial fertilizer is low, the application effect is good, and it does not pollute the environment. After use, it not only increases production, but also improves the quality of agricultural products. Therefore, it plays an important role in the sustainable development of agriculture in my country. With the development of ecological agriculture and green agriculture, people pay more and more attention to the harm of chemical pesticides and chemical fertilizers to soil and human beings. Restric...
