Abstract

The invention discloses a K-rich organic fertilizer and a production method thereof. The K-rich organic fertilizer is prepared by following steps: taking the mixture of chicken manure, residue of edible fungi and filings as raw material; turning over piles at 55-75 DEG C under the effect of VT-200 compound microbial inoculums and aerobically fermenting for 8-10 days; and then adding K-rich tobacco stalk powders, and continuously turning over piles for aerobically ferment for 10-15 days to obtain the K-rich organic fertilizer. The product comprises various effective components according to the weight percent: more than 10.0 percent of total nutrient, 2.6-3.3 percent of nitrogen, 2.8-3.5 percent of phosphorus and 4.5-5.1 percent of potassium. The total nutrient of the nitrogen, the phosphorus and the potassium is more than or equal to 10 percent, wherein the content of the potassium reaches more than 4.5 percent and is equivalent to 1.5-2.5 times of the content of the potassium in common organic fertilizer. The vegetable organic potassium is not easy to loss, and can be slowly released, thereby greatly improving the utilization ratio, reducing the application of inorganic K fertilizer, and achieving the effects of increasing the production and saving resources.

Description

A kind of K-rich organic fertilizer and production method thereof

Technical field

The present invention relates to a kind of K-rich organic fertilizer and production method thereof.

Background technology

Chemical fertilizer is still mainly used in fertilising in China rural area at present, but in the chemical fertilizer in nitrogen, phosphorus, potassium three elements, its potassium water-soluble big, very easy loss causes in the fertilizer utilization ratio of potassium low; The more important thing is the input and the unreasonable use of long-term a large amount of chemical fertilizer, can cause the variation of soil physical and chemical property,, and cause the health degeneration of soil and cause soil-borne disease constantly to rise as soil compaction; Can cause the reduction of soil microorganisms total amount and the minimizing of beneficial organism in addition.The results showed that on the use plot of common fertilizer agricultural chemicals, the microorganism total amount is lacked more than 50% than use high-effective microorganism compost! The application of organic fertilizers structure of then improving the soil increases soil basis soil fertility and beneficial microorganism structure and content.Therefore, fertilizer is a kind of important source of manure, and existing organic compost, nutrient has only about 6%, or is the phosphorus content height, and the phosphorus content height mainly is the fertilizer of high content of phosphorus, it mainly is to improve phosphorus content by adding a large amount of ground phosphate rock that contains, and its potassium content is lower; K-rich organic fertilizer seldom or does not at all have at present.

Summary of the invention

The object of the present invention is to provide a kind of K-rich organic fertilizer and production method thereof, to realize that potassium is not easy to run off; Its utilization ratio can be improved greatly, and the purpose of improving soil can be reached.

K-rich organic fertilizer is to be by following weight ratio by chicken manure, edible fungi residues, wood sawdust, tobacco rod powder: the product that chicken manure 700-1000, edible fungi residues 250-400, wood sawdust 200-300, tobacco rod powder 400-800 make through VT-200 composite fungus agent turning aerobic fermentation, the weight percent of various effective constituents is respectively in the product: total nutrient is more than 10.0%, nitrogen 2.6-3.3%, phosphorus 2.8-3.5%, potassium 4.5-5.1%.

The production method of K-rich organic fertilizer may further comprise the steps:

(1) with weight ratio be: chicken manure 700-1000, edible fungi residues 250-400, wood sawdust 200-300 are evenly mixed, 1 kilogram of VT-200 composite fungus agent of interpolation per ton, stacked 1-3 days, and once turned over throwing, aerobic fermentation 8-10 days every day when temperature rises to 55-75 ℃ of beginning; No longer rise to temperature;

(2) add tobacco rod powder 400-800 according to weight ratio, continued the turning aerobic fermentation 10-15 days, slowly descend to temperature, or the fertilizer color becoming brown, then is finished product.

Described chicken manure is dried poultrymanure or wet chicken manure or the mixture of the two, and the weight percent of various effective constituents is respectively in the chicken manure: nitrogen 3.9-4.8%, phosphorus 3.5-4.7%, potassium 3.4-3.3%, organic 57-61%;

The carbon-nitrogen ratio of described edible fungi residues is more than 60, no living contaminants.

The weight percent of various effective one-tenth is respectively in the described tobacco rod powder: potassium is more than 6.5%, and organic more than 45%, nitrogen phosphorus potassium total amount is more than 8.5%;

Carbon-nitrogen ratio is more than 500 in the described wood sawdust, and fresh nothing is gone mouldy.

The present invention is the K-rich organic fertilizer that the plant material tobacco rod powder with high potassium content produces by zymotechnique.Its nitrogen phosphorus potassium total nutrient is more than or equal to 10%, and wherein the content of potassium reaches more than 4.5%, is equivalent to potassium content 1.5-2.5 times of conventional fertilizer.And this vegetalitas organic potassium is difficult for running off, and can slowly discharge, and can improve its utilization ratio greatly, and using K-rich organic fertilizer can reduce using of inorganic potash fertilizer, reaches the effect of volume increase joint money.Can not take place that soil compaction and salinity are excessive, the health that can not cause soil is degenerated yet and cause the rising of soil-borne disease; More can not cause the reduction of soil microorganisms total amount and the minimizing of beneficial organism.Use this fertilizer as watermelon base manure, use 150 kilograms for every mu, the 20 kilograms of urea that topdress are carried seedling, the fertile 10 kilograms of urea of swollen melon add 5 kilograms of vitriolate of tartar and mu and use 50 kilograms of 45% composite fertilizers and add 20 kilograms of urea and compare the effective of application of organic fertilizers with 10 kilograms of vitriolate of tartar, the quality of watermelon of output is good, the sugariness height, sugar degree is than the general high one percentage point of sealing fertilizer.And the fertile cost of their usefulness is close, and quality but has obvious lifting, and output is also close, and the fertile economic benefit of the throwing of generation is the height of organic fertilizer then.
