Abstract

The invention relates to an organic fertilizer and a preparation method thereof. The organic fertilizer consists of dairy manure and crop waste. The organic fertilizer is prepared by the following method comprising the steps of: mixing the dairy manure and the crop waste uniformly in a fermentation tank; and when the moisture in the dairy manure is reduced to 50 to 60 percent and the temperature is raised to 40 DEG C, mixing RW rot promoting agent and crushed mushroom uniformly, applying the mixture to the fermentation tank, turning over the mixture by using a turnover machine, controlling the temperature within 80 DEG C, and completing fermentation in 12 to 15 days. The dairy manure and the waste mushroom bars or peanut shells are used as raw materials and selected from wastes in the agricultural production process, so that the agricultural wastes are secondarily utilized, the problems that the agricultural wastes are difficultly treated and environmental pollution is produced when the wastes are randomly stacked are solved, and the agricultural wastes can be transformed into the organic fertilizer with high effect by a biochemical process. The prepared organic fertilizer has rich organic nutrient content and relatively high nitrogen, phosphorus and potassium content, and is quick in the crop absorption and utilization process and low in application. In addition, compared with other similar processes for preparing the organic fertilizer, the method has the advantages that the method is simpler and easy in operation, does not occupy much manpower resource and saves the cost.

Description

A kind of organic fertilizer and preparation method thereof

Technical field

The present invention relates to a kind of organic fertilizer and preparation method thereof.

Background technology

Current society, people's environmental consciousness is more and more stronger.Used fertilizer mainly contains chemical fertilizer and organic fertilizer on the agricultural.After chemical fertilizer is applied to the farmland,, increased the weight of the deterioration of environment though, also soil even underground water have been produced the pollution that is difficult to repair simultaneously for farm crop provide nutrient.The a large amount of nutritive ingredients that not only contain the plant needs in the organic fertilizer; Relatively milder lasting to the nutrient supply of plant; Very long aftereffect is arranged, and can improve Soil structure after using, promote the formation of soil aggregate; Improve soil water-retaining, protect fertilizer and permeability, keep the microbial balance in the soil, the ability of raising soil disease and insect resistance.In addition, organic fertilizer derives from nature, and wide material sources effectively utilize agricultural wastes, have no pollution.

But existing organic fertilizer nutrient content is low, is difficult for decomposing, and absorption process is slow, can not in time satisfy the requirement of high crop yield.The long-pending system of traditional fertilizer and use are also very inconvenient, the making processes complex process.Publication number is that the patent of CN101468923A " organic fertilizer and preparation method thereof " by name need be handled under heating and pressurizing in the preparation process of organic fertilizer; Drop to normal pressure then; The liquid-solid mixture that obtains carries out liquid-solid separation, the making processes more complicated.

Summary of the invention

The present invention is directed to some problems of existing organic fertilizer and preparation method thereof existence, proposed a kind of active constituent content height, used timely, the easy decomposition of back crop absorption, the simple organic fertilizer of preparation technology and preparation method thereof.

Technical scheme of the present invention is: a kind of organic fertilizer, count by weight, and comprise following component:

Cow dung: 6.5-8

Agricultural waste material: 1

Preferably: described agricultural waste material is discarded mushroom rod or Pericarppium arachidis hypogaeae.

Another object of the present invention is to provide a kind of preparation method of organic fertilizer, may further comprise the steps:

1) cow dung is put into fermentation vat;

2) agricultural waste material is shone dry doubling and pulverize, put into fermentation vat and mix with cow dung;

3) moisture in cow dung drops to 50-60%, when temperature is increased to 40 ℃, imposes in the fermentation vat after the short rotten bacterium of RW and broken mushroom mixed;

4) turn over 1-2 time with turnover throwing machine, reach 55-65 ℃ second day temperature, turn over later every day and throw one time, temperature is controlled in 80 ℃;

During 5) by 12-15 days, drop to normal temperature, fermentation is accomplished, and obtains the organic fertilizer finished product.

Preferably: the stacking height to width ratio of cow dung in fermentation vat is 1: 4～5 in the described step 1).

The invention has the beneficial effects as follows: the present invention is a raw material with cow dung, depleted mushroom rod or Pericarppium arachidis hypogaeae; All take from the waste in the agricultural production process; Agricultural wastes are carried out second stage employ; Both solve agricultural wastes and be difficult to handle, stacked the problem of environmental pollution that produces everywhere, and can agricultural wastes have been become the higher organic fertilizer of fertilizer efficiency through biological process again.Because local cowboying family is many, a large amount of cow dungs of generation are difficult to handle, and stack everywhere, and the present invention has solved this local outstanding problem well, has increased income for the cowboying family again simultaneously.The organic fertilizer organic nutrient substance content that makes is abundant, and nitrogen, phosphorus, potassium content are higher, and crop absorption utilizes process very fast, and amount of application is little.In addition, the similar technology of producing organic fertilizer with other of technology of the present invention is compared, and is simpler, and operation does not take more manpower easily, saves cost.

Embodiment

Specific embodiment one: 6.5 tons of cow dungs are put into fermentation vat, and stacking highly is 1 meter, and width is 5 meters; 1 ton of discarded mushroom rod or Pericarppium arachidis hypogaeae are shone dry doubling pulverize, put into fermentation vat and mix with cow dung, the moisture in cow dung drops to 50%, when temperature is increased to 40 ℃, imposes in the fermentation vat after the short rotten bacterium of RW and broken mushroom mixed; Turn over 1-2 time with turnover throwing machine, reach 65 ℃ second day temperature, turn over later every day and throw one time, temperature is controlled at 70 ℃, during by 15 days, drops to normal temperature, and fermentation is accomplished, and obtains the organic fertilizer finished product.

Specific embodiment two: 4 tons of cow dungs are put into fermentation vat, and stacking highly is 1 meter, and width is 4 meters; 0.5 ton of discarded mushroom rod or Pericarppium arachidis hypogaeae are shone dry doubling pulverize, put into fermentation vat and mix with cow dung, the moisture in cow dung drops to 60%, when temperature is increased to 40 ℃, imposes in the fermentation vat after the short rotten bacterium of RW and broken mushroom mixed; Turn over 1-2 time with turnover throwing machine, reach 55 ℃ second day temperature, turn over later every day and throw one time, temperature is controlled at 60 ℃, during by 12 days, drops to normal temperature, and fermentation is accomplished, and obtains the organic fertilizer finished product.

Specific embodiment three: 1.5 tons of cow dungs are put into fermentation vat, and stacking highly is 0.5 meter, and width is 2.2 meters; 0.2 ton of discarded mushroom rod or Pericarppium arachidis hypogaeae are shone dry doubling pulverize, put into fermentation vat and mix with cow dung, the moisture in cow dung drops to 55%, when temperature is increased to 40 ℃, imposes in the fermentation vat after the short rotten bacterium of RW and broken mushroom mixed; Turn over 1-2 time with turnover throwing machine, reach 60 ℃ second day temperature, turn over later every day and throw one time, temperature is controlled at 80 ℃, during by 13 days, drops to normal temperature, and fermentation is accomplished, and obtains the organic fertilizer finished product.
