Fertilizer for conditioning continuous cropping obstacle soil and application method thereof

Abstract

The invention discloses a fertilizer for conditioning continuous cropping obstacle soil and an application method thereof, and particularly relates to the technical field of soil conditioning. The fertilizer is prepared by mixing an organic fertilizer and fermentation microorganisms according to a ratio of (2-4):1 and performing fermentation, wherein the organic material is prepared, by weight, 30-40 parts of corn straw, 20-30 parts of chicken manure compost, 5-15 parts of herb residue humus, 5-15 parts of sludge humic acid, 5-10 parts of bean cake, 6-8 parts of montmorillonite, 4-6 parts of calcium bentonite, 1-3 parts of zinc sulfate, 1-3 parts of magnesium sulfate, 1-2 parts of potassium nitrate and 2-4 parts of borax. The application method comprises the following steps: step 1, soil disinfection; and step 2, soil conditioning. According to the fertilizer prepared by the raw material formula, the contents of organic matters, nitrogen, phosphorus and zinc in soil can be increased, the soil can be improved, the soil fertility can be improved, the yield can be increased, the micro-ecological environment of the soil can be improved, the advantages of beneficial bacteria can be exerted, the propagation of harmful microorganisms can be inhibited, and the prevention and treatment effect on soil-borne diseases can reach about 70%.

Description

technical field [0001] The invention relates to the technical field of soil conditioning, and more specifically, the invention relates to a continuous cropping obstacle soil conditioning fertilizer and a use method thereof. Background technique [0002] In the production of greenhouses and greenhouses, due to the single planting stubble and the large amount of fertilization in successive years, abnormal growth occurs, resulting in a decline in production year by year, aggravation of pests and diseases, and even production can no longer continue. This phenomenon is called soil continuous cropping barriers. With the development of highly intensive and specialized production of vegetables, the soil problems of some crops have become increasingly prominent, which has become a major obstacle restricting the development of protected vegetables in our country, and people should pay enough attention to them; [0003] The causes of continuous cropping obstacles generally include the ...

AI Technical Summary

Problems solved by technology

[0003] The causes of continuous cropping obstacles generally include the accumulation of soil salinity, the accumulation of self-harming substances, the accumulation of soil-borne pathogens, the lack of certain nutrient elements in the soil, and the dissimilation of soil microbial populations. The commonly used methods to solve continuous cropping obstacles include crop rotation, chemical control, soil Disinfection, adding organic fertilizer, etc., but the effect is not ideal
