Anti-continuous-cropping microbial fertilizer and preparation method therefor

Abstract

The invention relates to a microbial fertilizer, and concretely relates to an anti-continuous-cropping microbial fertilizer and a preparation method therefor. The anti-continuous-cropping microbial fertilizer comprises 10-15 parts of composite microbial agent, 9-13 parts of urea, 16-20 parts of monoammonium phosphate, 15-20 parts of ammonium sulfate, 20-25 parts of potassium sulfate, 10-20 parts of humic acid, 2-5 parts of borax, 2-5 parts of zinc sulfate and 3-5 parts of magnesium sulfate. The composite microbial agent is mainly prepared from the following ingredients: 80-160kg / ton of soybean cake powder, 48-360kg / ton of starch maize, 100-280kg / ton of wheat bran and 30-80 kg / ton of fish meal. The composite microbial agent generates a lot of plant endogenous enzymes during the metabolism process, the absorption rate of crops to nutrition elements of nitrogen, phosphor, potassium and the like can be raised obviously, and rapid growth of crops is promoted. Growth and reproduction of harmful microorganisms of harmful bacteria, pathogen and the like are inhibited, toxic and harmful substances can be decomposed, and therefore continuous-cropping is controlled.

Description

(1) Technical field [0001] The invention relates to a microbial fertilizer, in particular to a microbial fertilizer resistant to heavy cropping and a preparation method thereof. (2) Background technology [0002] Continuous cropping, also known as continuous cropping, refers to the continuous planting of the same crop on a field. Many crops, such as legumes, melons, vegetables, strawberries and some Chinese herbal medicines, etc., are caused by plant root pathogens due to heavy cropping, resulting in plant wilt, leaf blight, viral diseases and other hazards, seriously affecting crop growth. With the increasingly serious situation of desertification and desertification in the world, the arable land is becoming less and less, and the contradiction of more people and less land in our country is more prominent. Increasing the multiple cropping index (repeated cropping) is the only way to solve the problem. However, the ensuing cropping diseases such as soil-borne diseases cause...

Problems solved by technology

At present, the main method of anti-stubble on the market is soil chemical disinfection to kill soil microorganisms. This method leads to either incomplete disinfection, or excessive use leads to soil compaction. What is more serious is to kill all microorganisms in the soil and destroy the micro-ecology. The balance of fertilizers leads to low fertilizer utilization rate and reduced soil aggregate structure and reduced water and fertilizer retention capacity.

[0004] Therefore, cropping disease has become a key topic of research and concern for agricultural experts and farmers, but there has been no major breakthrough for a long time, and this situation needs to be improved
