Embodiment 1

[0022] 1. After the rice stalks are harvested, the stalks are crushed into about 10cm long stalk segments;

[0023] 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;

[0024] 3. For every 1000 kg of rice straw, add 1 kg of urea, 0.1 kg of manganese oxide, 0.08 kg of hydroquinone, and 1.5 kg of phosphogypsum, mix well, and stack them in haystacks with a length of 3 meters, a width of 1.5 meters, and a height of 1 meter. Haystack humidity is 40%;

[0025] 4. Cover the haystacks with a plastic film to seal the haystacks. Turn the haystacks every 6 days in summer and every 12 days in spring and autumn. After 3-4 turns, spread out the haystacks and expose them to the sun for 3 days;

[0026] 5. The humus after exposure to the sun, together with the rice residue, is applied to the farmland as base fertilizer to plant crops.

[0027]

Embodiment 2

[0029] 1. After the wheat straw is harvested, the straw is crushed into 20cm long stalk segments;

[0030] 2. Add livestock and poultry manure according to 20% of the mass of wheat straw, and add water to make the straw section and livestock and poultry manure completely soaked;

[0031] 3. For every 1000 kg of wheat straw, add 6 kg of ammonium sulfate, 0.8 kg of manganese oxide, 0.1 kg of hydroquinone, and 4 kg of phosphogypsum, mix thoroughly, and stack them in haystacks with a length of 5 meters, a width of 3 meters and a height of 1.5 meters. , keep the humidity of the haystack at 50%;

[0032] 4. Cover the haystack with a plastic film to seal the haystack. Turn the haystack every 6 days in summer and every 12 days in spring and autumn. After 3-4 turns, remove the film and spread the haystack to expose to the sun for 4 days;

[0033] 5. Apply the mixed haystack residue and humus to the farmland as base fertilizer to plant crops.

[0034]

Embodiment 3

[0036] 1. When corn stalks are harvested, crush the stalks into 25cm long stalks;

[0037] 2. Add livestock and poultry manure according to 40% of the mass of corn stalks, and add water to make the straw section and livestock and poultry manure completely soaked;

[0038] 3. Add 4 kg of urea, 1 kg of manganese oxide, 0.4 kg of hydroquinone, and 10 kg of phosphogypsum for every 1,000 kg of corn stalks, mix well, and stack them in haystacks that are 11 meters long, 6 meters wide, and 2 meters high. Keep the haystack humidity at 55%;

[0039] 4. Cover the haystacks with a plastic film to seal the haystacks. Turn the haystacks every 6 days in summer and every 12 days in spring and autumn. After 3-4 turns, remove the film and spread the haystacks to expose to the sun for 4 days;

[0040] 5. Apply the mixed haystack residue and humus to the farmland as base fertilizer to plant crops.

Abstract

The invention discloses a method of producing soil humus with crop stalks and an application. The method comprises the following steps that the crop stalks are smashed after being harvested; an appropriate amount of livestock excrement, carbamide or ammonium sulfate, manganese oxide, hydroquinone and the like are added to the crop stalks, stirred uniformly, subjected to mixed stacking, fermented, sprayed with water, covered with a film at the periphery and sealed, and subjected to stack turning frequently. The soil humus can serves as a high-quality organic fertilizer and a soil organic matter to be applied into farmland for grain and vegetable cultivation, and has no environmental pollution; air pollution due to smashing of the crop stalks is avoided; the problem that the content of the organic matter in the farmland decreases is solved; the soil fertility is increased; greenhouse gas emission of the farmland is reduced; carbon sequestration of soil is promoted; and the development on ecological agriculture is promoted.

Description

[0001] technical field [0002] The invention belongs to the technical field of agriculture, and in particular relates to a method and application for producing soil humus from crop straws. [0003] Background technique [0004] 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. 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 still has problems such a...
