[0006] Straw returning to the field does not allow the crops to fully utilize the substances contained in the straw itself, and some crops cannot adapt to the soil after the straw is returned to the field, which will hinder the growth and development of the crops, and some may even die, making the direct return of the straw to the field cause serious damage. cut production
At present, there are also many people studying how to make straw into fertilizer and then return it to the field. The general metho

Example Embodiment

[0036] Example 1

[0037] A method for producing nitrogen slow-release organic fertilizer, including the following steps:

[0038] ① Send 400 parts by weight of straw into the pulverizer, pulverize to a particle size of 4mm, add waste molasses, wine tank and bran powder and mix evenly, then add 0.5% of the straw weight organic fertilizer inoculant, and mix well. Cover the film and place it in a fermentation tank at 45°C for 15 days of fermentation, during which the stack is turned over 3 times. After the last turn, the film is lifted and the temperature is controlled to 38°C. The fermentation is continued for 6 days to obtain fermented organic raw materials; During the process, the pile diameter is 1.5m, and the pile height is 1.2m; the bran powder is one or a mixture of peanut bran, rice bran, wheat bran, soybean bran, and rape bran; the straw, waste molasses, The weight ratio of the wine tank and the bran powder=35:7:3:11; the organic fertilizer inoculum is Saccharomyces cerevis...

[0052] Example 3

[0053] A method for producing nitrogen slow-release organic fertilizer, including the following steps:

[0054] ① Feed 410 parts by weight of straw into the pulverizer, pulverize to a particle size of 5mm, add waste molasses, wine tank and bran powder and mix evenly, then add 0.6% of the straw weight organic fertilizer inoculant, and mix well. Cover the film and place it in a 46°C fermentation tank for 16 days of pile fermentation, during which the pile is turned 3 times, after the last turn, the film is lifted, the temperature is controlled at 39°C, and the ventilation and fermentation are continued for 7 days to obtain fermented organic raw materials; During the process, the pile diameter is 1.6m and the pile height is 1.3m; the bran powder is one or a mixture of peanut bran, rice bran, wheat bran, soybean bran, and rape bran; the straw, waste molasses, The weight ratio of wine tank and bran powder=36:7:3.5:11.5; the organic fertilizer microbial agent is Bacil...

Abstract

The invention discloses a production method of a nitrogen slow-release type organic fertilizer. By means of the method, a urea formaldehyde slow-release nitrogen fertilizer is evenly mixed into an organic fertilizer, urea and formaldehyde are made to react under alkaline conditions to generate soluble small-molecular urea formaldehyde, the small-molecular urea formaldehyde is mixed with a raw material with monoammonium phosphate, the polymerization of the urea formaldehyde is promoted due to the acidity of the monoammonium phosphate, the urea formaldehyde and other raw materials can be easilywetted and mixed sufficiently to form unsoluble urea formaldehyde, the utilization of the slow-release nitrogen fertilizer can be effectively improved in the use process, and the slow-release long-term effect is realized, and the utilization rate of the fertilizer is increased; the purpose of reusing straw and agricultural product processing waste is achieved; when the fertilizer is used as a cropfertilizer, the fertilizer consumption is reduced, meanwhile the crop yield can be greatly improved, the requirements of crop for a nitrogen fertilizer in the whole growth period are met by one timeof fertilizer applying, the growth efficiency and survival rate of crop are increased, time, labor and manpower are saved for farmers, production cost is reduced, pollution is reduced, and the ecological environment is protected.

Description

technical field [0001] The invention belongs to the technical field of slow-release organic fertilizer production, in particular to a production method of nitrogen slow-release organic fertilizer. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining part of wheat, rice, corn, potatoes, oilseeds, cotton, sugar cane and other crops (usually coarse grains) after harvesting seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource, and straw is also a roughage. It is characterized by high crude fiber content (30%-40%), and contains lignin, etc. According to the statistics of Zhang Fudao et al., leguminous crop straw contains more nitrogen, gramineous crop straw contains more potassium, and the nutrients provided by crop straw Accou...
