Problems solved by technology

However, the traditional composting method uses open-air composting, which has the disadvantages that the composting area is relatively large, and the composting process needs to be turned over, which is time-consuming and laborious, and it is difficult to move the composting pile, and the odor generated by composting affects the environment.

Embodiment 1

[0034] A straw composting method, the specific steps are as follows:

[0035] Crush wheat straw into 3‐5cm particles, weigh 200kg of straw particles, spray with 2% of Bacillus subtilis, 0.5% of Aspergillus niger, 3% of Aspergillus oryzae, 1% of 3% of Clostridium thermocellum, 1% of Pseudomonas mendoza, 2% of Phanerochaete chrysosporium and 10kg of fast-rot fungicide of surplus water, then spray 1% of soluble starch, 5% Glucose, 3% corn steep liquor, 5% ammonium chloride, 1% potassium dihydrogen phosphate and the rest of water 20kg, and finally spray water to adjust the water content of the material to 50%, mix well and pack Put it into 5 biodegradable plastic bags prepared by pure PBS to make a compost bag. The upper and lower ends of the plastic bag have a diameter of 5 cm air valves, and a plastic pipe of PBS with a diameter of 5 cm is connected between the air valves. The surface is covered with small holes with a diameter of 4mm, and the density of the small holes is 2 / cm...

[0037] A straw composting method, the specific steps are as follows:

[0038] Crush wheat straw into 3-5cm particles, weigh 200kg of straw particles, and spray 2% of Bacillus subtilis, 0.5% of Aspergillus niger, 3% of Aspergillus oryzae, 1% of Thermosporidium sp. 3% of Clostridium thermocellum, 1% of Pseudomonas mendoza, 2% of Phanerochaete chrysosporium and 10kg of fast-rot fungicide of surplus water, then spray 1% of soluble starch, 5% Glucose, 3% corn steep liquor, 5% ammonium chloride, 1% potassium dihydrogen phosphate and the rest of the mixed nutrient solution 20kg of water, and finally spray water to adjust the water content of the material to 50%, mix the fertilizer After about 18 days, the moisture in the outer layer of the compost heap volatilized too quickly, and basically did not decompose. The inner layer also lost moisture, and the decomposition was slow, and only part of the straw was decomposed.

Embodiment 3

[0040] A straw composting method, the specific steps are as follows:

[0041] Crush wheat straw into 3-5cm particles, weigh 200kg of straw particles, and spray 1% of Bacillus subtilis, 2% of Aspergillus niger, 1.5% of Aspergillus oryzae, 2% of Thermosporidium sp. 1% of Clostridium thermocellum, 2% of Pseudomonas mendoza, 1.5% of Phanerochaete chrysosporium, and 10kg of fast-rot fungicides containing 3% of soluble starch and 1% of water. Glucose, 10% corn steep liquor, 2% ammonium chloride, 2% potassium dihydrogen phosphate and the rest of the mixed nutrient solution 20kg, and finally spray water to adjust the water content of the material to 50%, after mixing, put it into Compost bags made from 5 plastic bags blended with 70-80% PBS and 20-30% starch by weight with air valves at the upper and lower ends. The upper and lower ends of the plastic bags have diameters It is a 5cm air valve, and a PBS plastic tube with a diameter of 5cm is connected between the air valves. The wall...

Abstract

The invention discloses a plant straw composting method, which comprises the following steps: crushing plant straws into straw particles of 3-5cm; evenly spraying rapid-rotting fungicide and nutrient solution on the surfaces of the straw particles; spraying water to the obtained straw particles, regulating the content of material moisture to 45-55%, evenly mixing materials and then filling into a biodegradable plastic bag and sealing a bag opening to obtain a composting bag, and standing for 15-25 days, thus completing the composting. The method is simple and convenient to operate, and can be realized flexibly in the edge of a field; not only can the composting bag produced by adopting the biodegradable plastic bag be heat-insulating and moisturized, but also the plastic bag can also be finally decomposed into a part of compost by microorganisms to increase the fertilizer efficiency.

Description

technical field [0001] The invention relates to the field of plant composting, in particular to a plant straw composting method. [0002] technical background [0003] my country is a big agricultural country, which produces hundreds of millions of tons of wheat, soybean, rice, corn and other plant straws every year. At present, the comprehensive utilization rate of plant straws in my country is relatively low, and the treatment methods of plant straws are mainly incineration and direct return to the field. The burning of straw has caused a serious waste of resources. Especially in recent years, crop straw burning has become a new source of air pollution. Every year during the summer and autumn harvests, a large amount of wheat, corn, rice and other stalks are always burned in the fields, producing a lot of thick smoke, which has a serious impact on people's living environment and transportation. Burning has caused serious environmental problems, and the government has ban...
