Organic fertilizer for killing underground injurious insect and preparation method thereof

Abstract

The invention belongs to organic fertilizer, and in particular relates to organic fertilizer for killing underground injurious insects and a preparation method thereof. The organic fertilizer comprises the following components in part by weight: 1000 parts of tobacco stalk, 25 to 30 parts of dry livestock manure, 5 to 10 parts of urea and 3 to 5 parts of solid high-efficient microorganism zymogeneous bacteria. The preparation method comprises the following steps that: the tobacco stalk is smashed; the livestock manure is dried and dehydrated; the urea is added to be uniformly mixed; the zymogeneous bacteria is inoculated; the moisture and the pH value are adjusted, fermentation stocks are piled up, and black plastic film covers the fermentation stocks, so the fermentation stocks are undertaken the anaerobic fermentation; after the temperature is increased, the stocks are turned for a plurality of times until the materials are fermented and matured and the size is reduced to two thirds of that of the original stocks; and the fermented stocks are naturally ventilated and dried and are bagged to store. The organic fertilizer has the advantages that the fertilizer efficiency is high, the underground injurious insects can be killed, the content of the organic colloid of the soil is increased after the application of the fertilizer, the fertilizer and water maintaining capacity of the soil is improved, the period of validity of the fertilizer is prolonged, and the probiotics in the soil can be compensated.

Description

technical field [0001] The invention belongs to organic fertilizers, in particular to an organic fertilizer for killing underground pests and a preparation method thereof. Background technique [0002] Soil is the place where underground pests inhabit, reproduce and survive. The physical and chemical properties of soil, such as the size of soil particles, aggregate structure, pH value, organic matter and salt content, etc., have a direct impact on the population composition, geographical distribution and quantitative changes of underground pests. influences. Underground pests destroy the soil environment suitable for crop growth, eat the roots of crops, bite off the stems of crops, seriously damage the growth of crops, and seriously affect the yield. It is difficult to prevent and control underground pests in agricultural production. At present, chemical control is the main method, supplemented by agricultural control. While chemical control kills subterranean pests, it is...

AI Technical Summary

Problems solved by technology

At present, the by-products of tobacco production and the utilization of tobacco straw resources have not yet been industrialized. There are problems of low technical content, low level of comprehensive utilization, low added value, and short industrial chain, which not only causes a lot of waste of resources, but also causes environmental pollution.

At present, the problems caused by improper disposal of tobacco stalks are serious, such as open-air burning of tobacco stalks, which causes waste of resources, damages soil fertility, pollutes the atmosphere, and affects traffic; natural fermentation can cause accumulation of toxic substances in the soil, loss of soil nutrients, and the spread of pests and diseases, etc.

The problem of resource utilization of tobacco stalks has existed for a long time and cannot be solved, and has become a big problem that needs to be solved urgently
