Embodiment 1

[0036] 1. When rice stalks are harvested, the stalks are crushed into about 15cm long stalk segments;

[0037] 2. Add livestock and poultry manure according to 10% of the mass of rice straw, and add water to make the straw section and livestock and poultry manure completely soaked, and keep the water content at about 40%;

[0038] 3. Add 2 kg of urea for every 1000 kg of rice straw, mix well, stack haystacks with a length of 4 meters, a width of 2 meters, and a height of 1 meter, and add water to keep the humidity of the haystack at 40%;

[0039] 4. Cover the haystacks with a plastic film and seal them around. Turn the haystack every 5 days in July, and turn it every 12 days in April or October, and inoculate the mushroom strains after 4 turns;

[0040] 5. After the mushrooms are grown and harvested, mix the haystack residues and straw mushroom residues together, then add livestock and poultry manure according to 15% of the total mass of the haystack residues and mushroom resi...

Embodiment 2

[0043] 1. After the wheat straw is harvested, the straw is crushed into 20cm long stalk segments;

[0044] 2. Add livestock and poultry manure according to 20% of the mass of wheat straw, and add water, so that the straw section and livestock and poultry manure are completely soaked, and the water content is kept at about 50%;

[0045] 3. Add 10 kilograms of ammonium sulfate to every 1000 kilograms of wheat straw, mix well, pile up a haystack with a length of 8 meters, a width of 4 meters, and a height of 1.5 meters, and add water to keep the humidity of the haystack at 50%;

[0046] 4. Cover the haystacks with a plastic film and seal them around. Turn the haystack every 5 days in August and every 12 days in May, and inoculate straw mushrooms after 3 turns;

[0047] 5. After the straw mushroom grows and harvests, mix the haystack residue and straw mushroom residue together, then add livestock and poultry manure according to 30% of the total mass of the haystack residue and str...

Embodiment 3

[0050] 1. When corn stalks are harvested, crush the stalks into 25cm long stalks;

[0051] 2. Add livestock and poultry manure according to 45% of the mass of corn stalks, and add water to make the straw section and livestock and poultry manure completely soaked, and keep the water content at about 60%;

[0052]3. Add 5 kg of urea for every 1000 kg of corn stalks, mix well, stack haystacks with a length of 10 meters, a width of 6 meters, and a height of 2 meters, and keep the humidity of the haystack at 60%;

[0053] 4. Cover the haystack with a plastic film and seal it around. Turn the haystack every 5 days in summer, and turn it every 12 days in spring and autumn. After 3-4 turns, inoculate the edible fungus Pleurotus ostreatus;

[0054] 5. After the Pleurotus ostreatus grows and harvests, mix the haystack residue and Pleurotus ostreatus residue together, then add livestock and poultry manure according to 45% of the mass of the haystack residue and Pleurotus ostreatus residu...

Abstract

The invention provides a method for developing ecological agriculture through resource utilization of crop straws and application thereof. The method is realized by the following steps: the crop straws are smashed during or after harvesting; proper amounts of livestock excrement, urea, ammonium sulfate and the like are added for mixed stacking and fermenting; edible fungus strains are inoculated; edible fungus are planted; after the edible fungus are harvested, the stacked organic wastes are mixed with a proper amount of livestock excrement, and are applied in farm lands as high-quality organic fertilizers. Grains and vegetables are planted without polluting environment, so that the air pollution due to the smashing of the crop straws is solved, the problem of reduced soil organic matters in the farm lands is solved, the soil fertility is improved, and the development of the ecological agriculture is promoted.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a method and application for utilizing crop stalks as resources to develop ecological agriculture. Background technique [0002] In 2009, the National Development and Reform Commission and the Ministry of Agriculture jointly issued a document requiring all localities to accelerate the comprehensive utilization of straw, gradually form a virtuous circle of straw resource development and utilization, realize the commercialization and recycling of straw, and promote the construction of a resource-saving and environment-friendly society. [0003] my country's crop stalks have a large quantity, variety and wide distribution. They are the main living fuel for rural residents, feed for large livestock and organic fertilizers. A small part of them are used as industrial raw materials and base materials for edible fungi. However, the comprehensive utilization of straw st...
