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

Embodiment 1

[0053] Crush the tobacco stalks into small pieces of 5cm, take the crushed tobacco stalks and cow dung and mix them with a mixer to make 1000Kg of the main material, add 3Kg of solid high-efficiency microbial mixed bacteria agent and 10Kg of urea and other auxiliary materials, and add 300Kg of water to make a 2.5-meter-wide , The 1.2-meter-high fermented pile with the top flattened, covered with a black plastic film, for natural fermentation of the mixed material. After 3 to 4 days, use a turning and throwing machine to turn it once, and pile it into the original shape after turning it; add water when turning it, and keep the moisture content of the pile at 65%. After 15 days, it is fermented and decomposed, dried with natural ventilation, put into a granulator, granulated and formed into tobacco straw organic fertilizer granules capable of killing underground pests, and packaged for delivery.

Embodiment 2

[0055] Preparation of solid high-efficiency microbial fermentation bacteria:

[0056] Take 10 kg each of rotten tobacco, corn, and wheat straw, 15 kg each of pond mud and chicken manure, and select high-efficiency microbial strains by conventional methods; put the high-efficiency microbial strains into a sterile triangular flask, wash with sterile saline, and shake well to prepare Obtain a high-efficiency microbial strain suspension; inoculate the high-efficiency microbial strain suspension into a culture bottle, and cultivate at 28°C and 180r / min for 24 hours to obtain a strain seed liquid; take the seed liquid and inoculate it into a fermentation bottle with a concentration of 10% to expand and cultivate for 48 hours The fermented liquid is obtained; the fermented liquid and the sterilized bran are mixed and fermented at a ratio of 1:1 and dried for 48 hours to prepare a solid high-efficiency microbial fermentation bacterium.

Embodiment 3

[0058] Grind the tobacco stalks into 4cm segments, take the crushed tobacco stalks, mix them with cow dung to form 1000Kg of material, add 5Kg of solid high-efficiency microbial composite bacterial agent and 5Kg of urea; The fertilizer has high fertilizer efficiency and good insecticidal effect.

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...
