Biological compound fertilizer for preventing crop diseases

Abstract

The invention discloses a biological compound fertilizer for preventing crop diseases, and the biological compound fertilizer is characterized by including the following materials by weight: 80-90 parts of crop straw, 0.01-0.02 parts of aschersonia montagne powder, 9-12 parts of vegetable cake, 90-120 parts of chicken manure, 30-40 parts of rice bran, 50-60 parts of pig manure, 8-10 parts of monocalcium phosphate, 6-9 parts of trimetapyrophosphate, 0.1-0.2 part of bacillus thuringiensis powder, 0.003-0.008 part of bacillus thuringiensis var powder, 3-9 parts of litsea cubeba, 9-12 parts of ophiopogon root and 1-2 parts of radix stemonae. The biological compound fertilizer not only can effectively control the underground pests, reduce the pest reproduction rate, drives and kills the underground pests, also has the effects of preventing a variety of diseases such as damping off, blight, greensickness, ceitocybe bescens and the like.

Description

technical field [0001] The invention relates to a biological compound fertilizer for preventing crop diseases. Background technique [0002] After the invention of organic chemical pesticides in the 1940s, it greatly enhanced the ability of human beings to control the damage of diseases and insect pests, and made a significant contribution to our restoration of crop yield losses. However, the long-term dependence and extensive use of organic synthetic chemical pesticides have brought about a series of well-known problems such as environmental pollution, ecological balance damage and food safety, and have brought many adverse effects on promoting the sustainable development of the agricultural economy. Chemical fertilizers can increase the yield of crops, but long-term application of chemical fertilizers will cause many disadvantages, including soil compaction and product quality decline. Residents in both urban and rural areas feel that vegetables are becoming less and less...

Problems solved by technology

However, the long-term dependence and extensive use of organic synthetic chemical pesticides have brought about a series of problems such as environmental pollution, ecological balance damage and food safety, which have brought many adverse effects on promoting the sustainable development of agricultural economy.

Chemical fertilizers can increase the yield of crops, but long-term application of chemical fertilizers will cause many disadvantages, including soil compaction, product quality decline, etc.

Residents in both urban and rural areas have the feeling that vegetables are becoming less and less fragrant, and the aroma of rice is becoming weaker and weaker. Excessive use of chemical fertilizers is one of the main reasons.
