Abstract
The invention relates to a method for preparing an organic fertilizer from agricultural wastes, comprising the following steps: pretreating fresh cow dung, straw and corncob used as raw materials, mixing the pretreated raw materials with mixed fermentation broth No. I uniformly, adding water to ferment, increasing the temperature to 60-70 DEG C, keeping the temperature, and fermenting for 2 to 3 days; adding mixed fermentation broth No. II after decreasing the temperature to 40 DEG C, mixing the mixed fermentation broth No. II with the fermented materials uniformly, and continuing to ferment for 5 to 8 days; sieving after the fermented materials are aired or dried, packaging separately, and mixing the materials in large particle size with the raw materials for later use, wherein the materials in large particle size are used as the fermentative bacterium carrier. The method has the advantages that the agricultural wastes are fully utilized and changed into valuable materials, the pathogens in the straw and the corncob are eliminated by fermenting, and the content of organic matters in the obtained organic fertilizer is more than 55%, the content of NKP is more than 3% and the content of water is less than 15%, therefore, the soil properties can be effectively improved, and the crop yield is increased.
Description
Technical field
The present invention relates to the comprehensive utilization of agricultural wastes, particularly a kind of method of utilizing agricultural wastes to make fertilizer.
Background technology
The annual stalk output of China reaches 700,000,000 tons, but straw utilization rate is but not high, and utilizes the state of the art of mode lower, even still has the phenomenon of crop straw burning, causes certain wasting of resources and environmental pollution.In stalk Fertilizer Transformed, more common way has direct returning to farmland, also burns also field and cross also field of abdomen of field, stack retting.
Direct returning to farmland is on the basis of mechanized operation, crop harvesting simultaneously to stalk pulverize and spreading in field, stalk rots through turning over after burying, thereby reach the object that increases the soil organism, the nutrient of stalk is retained in soil, but the sick worm's ovum in stalk etc. is not processed, and easily causes disease and pest.After crop straw burning, the plant ash obtaining is applied in field, but after crop straw burning, nitrogen loss is serious, and the environmental pollution producing is larger.Cross abdomen also field be the second stage employ to stalk, stalk is after livestock digestion, most of nutritive substance is absorbed, during excrement of animals is manured into soil, thereby improve in a large number the soil organism, soil ulmin, and change the physico-chemical property of soil, but the pathogenic bacterium that may exist in ight soil are not processed, and easily cause harm.
What use was more at present is straw compost technology, needs certain compost place and machinery, and the degrading microorganism of breeding high-efficiency.By cow dung, stalk and corn cob mixed fermentation, can improve fermentation rate, shorten fermentation time, through thermophilic fermentation, can kill disease and pest and the most of pathogenic microorganism in cow dung or stalk.
Summary of the invention
The object of the invention is to for above-mentioned existing problems, provide a kind of agricultural wastes that utilize to make high organic content, the method for fertilizer safely and effectively, to realize the recycling to agricultural wastes, the fertilizer obtaining can improve soil property, can improve crop yield simultaneously.
Technical scheme of the present invention:
Utilize agricultural wastes to make a method for fertilizer, step is as follows:
1) take fresh cow dung, stalk and corn cob as raw material, raw material is carried out obtaining fresh cow dung diluent, stalk particle and corn cob granule after pre-treatment;
2) add water after mixing with mixed fermentation bacterium liquid I number through pretreated fresh cow dung diluent, stalk particle and corn cob granule, then carry out compost fermentation, turning every day once and keep humidity more than 40%, until temperature, rise to after 60-70 ℃, maintain this temperature 2-3 days that ferments again;
3) when the temperature of fermentation materials drops to 40 ℃, add II mixed fermentation bacterium liquid and mix with above-mentioned fermentation materials, every day, turning was 2-3 time, keeping humidity more than 40% and under ventilation condition, continued fermentation 5-8 days;
4) after fermenting process finishes, above-mentioned fermentation materials carried out air-dry or dried, moisture is down to below 15%, then fermentation materials being screened, the material of large particle diameter continues to use after continuing to mix with raw material as zymophyte carrier.
In described raw material, the ratio of weight and number of fresh cow dung, stalk and corn cob is 25-30:60-70:5-10.
The method of described raw materials pretreatment is: fresh cow dung and water is by weight for 1:1 is mixed to get fresh cow dung diluent, and the PH that adjusts fresh cow dung diluent is 6-8; Crushed stalk is processed, and particle diameter is 2-10mm; Corn cob is pulverized and is processed, and particle diameter is 2-5mm.
Described I mixed fermentation bacterium is mixed and is formed by subtilis and bacillus acidocldarius, and the weight ratio of subtilis and bacillus acidocldarius is 1:1, and the add-on of I mixed fermentation bacterium is the 1-3% of fermentation materials weight; The add-on of water is the 40-50% of mixture weight.
Described II mixed fermentation bacterium is comprised of bacillus megaterium and the mould mixing of healthy and free from worry wood, and the mould weight ratio of bacillus megaterium and healthy and free from worry wood is 1:1, and the add-on of II mixed fermentation bacterium is the 2-4% of fermentation materials weight.
Described bake out temperature is no more than 60 ℃.
The screening of described fermentation materials is 20 orders.
Advantage of the present invention is:
1) make full use of agricultural wastes, turn waste into wealth.
2) process by fermentation, eliminated the pathogenic agent existing in stalk and cow dung.
3) organic content of the fertilizer obtaining is high, and NPK content is higher, can effectively improve soil property, improves crop yield.
