Embodiment 1

[0027] Embodiment 1 (by weight and number ratio, the same below)

[0028] 5kg of corn stalks crushed to ≤40 mesh (about 25% water content) and 1kg peat (about 25% water content), 60g of magnesia, 180g of trace elements (ZnSO 4 : Borax : MnSO 4 : FeSO 4 :(NH 4 ) 2 MoO 4 =50:5:14:30:1) and 5kg of poultry manure (water content about 75%) are evenly mixed and treated, adding microbial agent "301" agent (one ten-thousandth of the dry basis weight of organic fertilizer- 3 / 10,000), piled up in a wooden tank in the form of triangular strips for open-air composting. According to the measurement results of C and N content in the raw materials, the water content of the mixed material is adjusted to about 60%, the carbon-nitrogen ratio is adjusted to about 30:1, and the open-air aerobic fermentation process is adopted. The fermentation period is 25 days. The first two weeks are turned over 3 times a week, and the next two weeks are turned over twice a week, a total of 10 times. The ...

Embodiment 2

[0031] Crush 5.35kg to ≤40 mesh corn stalks (about 30% water content) and 0.94kg peat (about 20% water content), 30g magnesia, 150g trace elements (ZnSO 4 : Borax : MnSO 4 : FeSO 4 :(NH 4 ) 2 MoO 4=50:5:14:30:1) and 3.6kg of poultry manure (about 65% water content) were uniformly mixed and treated, and 180g of urease inhibitor NBPT (crushed to ≤60 mesh) was added to maintain nitrogen and deodorize, add Microbial agent "301" agent (1 / 10,000-3 / 10,000 of the dry weight of organic fertilizer) is stacked in a wooden tank in the form of triangular strips for open-air composting. According to the measurement results of C and N content in the raw materials, the water content of the mixed material is adjusted to about 60%, the carbon-nitrogen ratio is adjusted to about 25:1, and the open-air aerobic fermentation process is adopted. The fermentation period is 28 days. The first two weeks are turned over 3 times a week, and the next two weeks are turned over 2 to 3 times a week, for...

Abstract

The invention relates to an organic fertilizer, and in particular relates to an efficient organic fertilizer and a preparation method thereof. The fertilizer comprises the following concrete components in parts by weight on dry basis: 10-25 parts of livestock manure, 60-70 parts of cornstalk, 1-3 parts of urease inhibitor N-(n-butyl)triophosphoric triamide (NBPT), 10-20 parts of turf, 0-3 parts of trace elements and 0-1 part of magnesite. The principle of the invention is as follows: the ratio of carbon to nitrogen in the organic material is controlled, the urease activity is controlled, the ammonia ions are stabilized, the utilization ratio of nitrogen is improved and the ratio of nitrogen to phosphorous to potassium is kept relatively stable in the soil, thus achieving the application effect of balanced fertilization. The fertilizer has the following advantages: the utilization ratio of fertilizer nutrients can be remarkably improved; various nutrients essential to growth of plants can be satisfied and supplied; and the soil is improved, the ecological environment is protected, the growth of plants is conditioned and the yields and quality of the crops are improved.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to a high-efficiency organic fertilizer and a preparation method thereof. Background technique [0002] At present, the pollution of solid waste such as sludge, urban garbage, straw, poultry manure, etc. has become a prominent problem of environmental pollution, especially with the rapid development of intensive breeding industry, the pollution of poultry manure has developed rapidly. If it cannot be effectively treated, it will seriously affect the ecological environment and even endanger human health. High-temperature composting is an effective way to convert solid waste into high-quality organic fertilizers in a harmless and resourceful manner. High-temperature composting decomposes organic waste, which has the characteristics of short processing time and thorough harmlessness. Compost products are good soil conditioners and organic fertilizers because they are rich in humus and mineral...
