Abstract

The invention discloses a preparation method of a soil conditioning type disease-resistant yield-increasing water-soluble fertilizer additive, which comprises the following steps of: mixing bacillus subtilis zzl-002 powder and aminated nano silicon dioxide powder according to the mass ratio of 1: (1-5) to obtain the soil conditioning type disease-resistant yield-increasing water-soluble fertilizeradditive. The water-soluble fertilizer additive provided by the invention has the following characteristics: (1) the microbial agent is a pure biological agent, is harmless to human bodies, does notpollute the environment, and can solve the environmental problem caused by chemical pesticide pollution; meanwhile, after the microbial agent is applied to soil, the soil quality can be improved, andthe microbial agent has a positive effect on reducing diseases; (3) the microbial agent provided by the invention can effectively prevent and treat potato scab; (4) the fertilizer additive can reducethe fertilizer loss by 20-30% and reduce the use amount by 20-30%; (5) the weight ratio of the fertilizer additive provided by the invention is 5-10%; and (6) the method is rich in raw materials, lowin cost, environment-friendly, simple in process, labor-saving and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to the technical field of soil conditioning. Background technique [0002] With the gradual increase in the scale, regionalization and specialization of agricultural production in my country, the increasing use of chemical fertilizers and pesticides, coupled with high-intensity planting modes such as continuous cropping, has led to the widespread occurrence of salinization, the deterioration of soil microbial ecology, and soil-borne diseases. Increase the weight of year by year, bring huge economic loss to the grower. Most of the pathogenic bacteria of soil-borne diseases survive in the soil and diseased residues for a long time, and spread in various forms, making it difficult to eradicate. The lack of effective prevention and control measures has become an important bottleneck restricting the sustainable development of the agricultural industry. Therefore, research and develop...
