Embodiment 1

[0030] A preparation method of static high-temperature compost, which comprises the following steps:

[0031] 1) Stack 900 tons of wheat straw into haystacks with length, width and height of 150m, 6m and 3m respectively.

[0032] 2) Use a water pump to evenly inject 700 tons of water from the top of the haystack to ensure that the haystack is thoroughly watered from top to bottom.

[0033] 3) After 5 days, inject 300 tons of water evenly from the top of the haystack again, and evenly spray 30 tons of ammonium chloride, 2.5 tons of composite bacterial agents, and 30 tons of water on the top of the haystack. The composite bacterial agent is a mixture of Aspergillus niger, Penicillium, Trichoderma viride, Geobacillus stearothermophilus, and its weight ratio is 5:2:3:3; the total effective number of viable bacteria of the composite bacterial agent is 8× 10 8 individual / mL.

[0034] 4) Cover the haystack with a plastic sheet and compact it around, and make high-temperature compo...

Embodiment 2

[0041] A preparation method of static high-temperature compost, which comprises the following steps:

[0042] 1) Stack 1000 tons of wheat straw into haystacks with length, width and height of 200m, 6m and 4m respectively.

[0043] 2) Use a water pump to evenly inject 900 tons of water into the haystack from the top of the haystack to ensure that the haystack is thoroughly watered from top to bottom.

[0044]3) After 6 days, inject 350 tons of water evenly from the top of the haystack again, and evenly spray 7 tons of ammonium chloride, 7 tons of ammonium sulfate, 7 tons of ammonium bicarbonate, 3.5 tons of compound bacterial agents, and 50 tons of water system on the top of the haystack. The resulting aqueous solution. Described composite bacterial agent is the mixture of Trichoderma reesei, Trichoderma harzianum, Phanerochaete chrysosporium, Metarhizium anisopliae, and its weight ratio is 3:1:3:2; The total effective number of viable bacteria of described composite bacterial...

Embodiment 3

[0051] A preparation method of static high-temperature compost, which comprises the following steps:

[0052] 1) Pile 500 tons of wheat straw and 500 tons of corn straw together into several haystacks with length, width and height of 50m, 5m and 2.5m respectively. Wherein, the corn stalks are crushed to a length of about 4-7 cm before composting.

[0053] 2) Use a water pump to evenly inject 850 tons of water from the top of the haystack to ensure that the haystack is thoroughly watered from top to bottom.

[0054] 3) After 6 days, inject 380 tons of water evenly from the top of the haystack again, and evenly spray 5 tons of urea, 5 tons of ammonium chloride, 12 tons of ammonium bicarbonate, 3 tons of compound bacterial agent, and 40 tons of water on the top of the haystack. of aqueous solution. Described composite bacterial agent is the mixture of Penicillium, Aspergillus oryzae, Trichoderma reesei, Pleurotus pellagra, Geobacillus stearothermophilus, Saccharomyces cerevisia...

Abstract

The invention provides a preparation method of high-temperature compost. The method comprises the steps that 900-1300 parts of crop straw, 5-40 parts of nitrogenous fertilizer and 1.5-6 parts of microbial agents are taken; the crop straw is composted into a straw pile; 700-900 parts of water is evenly injected from the top of the straw pile; 300-400 parts of water is evenly injected from the top of the straw pile again after 2-6 days; the nitrogenous fertilizer and the microbial agents are dissolved in 30-50 parts of water, an aqueous solution of the nitrogenous fertilizer and the microbial agents is prepared, and the aqueous solution of the nitrogenous fertilizer and the microbial agents is evenly sprayed on the straw pile; the the straw pile is covered with plastic cloth and the periphery of the straw pile is compacted, and the high-temperature compost is prepared after the straw pile is fully rotten. According to the compost preparation method, two-time water injection is adopted, the defects that water absorption difficulty of the crop straw is high, and the water content needed by microorganism reproduction is difficult to achieve are overcome, the prepared high-temperature compost is high in rotten speed, and the rotten degree is high.

Description

technical field [0001] The invention belongs to the field of crop stalk recycling and relates to a high-temperature compost composition, high-temperature compost and a preparation method thereof. Background technique [0002] my country produces more than 700 million tons of crop straw every year, 70% of which are directly burned, and only 2.6% are used after technical treatment. Direct burning of crop stalks not only wastes resources, pollutes the environment, reduces soil fertility, aggravates soil compaction, but also affects traffic safety, social production and people's lives. It has become a serious and common economic and social problem. [0003] At present, there are some methods of using straw to prepare high-temperature compost, but the existing methods are complicated, the preparation cost is high, the compost decomposes for a long time, and the decomposing effect is not good, which is not conducive to farmers' direct composting of straw in the field.
