Embodiment 1

[0062] The method for returning livestock and poultry manure to fields by spraying straw powder, comprising the following steps:

[0063] 1. Coarse crushing of straw when harvesting corn

[0064] After the corn enters the mature stage, it is harvested with a corn combine harvester, and the corn stalks are crushed (length < 10 cm), and the height of the stubble is < 5 cm, and they are evenly scattered in the field.

[0065] 2. Gather straw

[0066] The corn stalks scattered in the 8 ridges were gathered in the middle 2 ridges by using the tractor towed finger-disc rake.

[0067] 3. Spraying manure and decomposing microbial preparations

[0068] The sewage suction truck absorbs the feces stored in the pig farm oxidation pond, and adds 0.1% (w / w) decomposing microbial preparations to the sewage suction truck. After mixing and stirring, the mixture is evenly sprayed on the straw surface, and the nitrogen application standard per hectare of cultivated land is 50kg.

[0069] 4. ...

Embodiment 2

[0082] The method for returning livestock and poultry manure to fields by spraying straw powder, is characterized in that it includes the following steps:

[0083] 1) While harvesting the corn with a corn combine harvester, crush the corn stalks to a length ≤ 10 cm, and evenly scatter them in the field;

[0084] 2) Gather the corn stalks scattered on the 8 ridges in the middle 2 ridges by using the tractor towed finger-disc rake;

[0085] 3) Take the livestock and poultry manure stored in the oxidation pond of the farm, add a decomposing microbial preparation to it at a ratio of 0.1% w / w, stir evenly, and then evenly spray the mixture on the straw surface;

[0086] 4) After the manure on the surface of the straw is naturally air-dried, crush it to a length of 2 to 5 cm, then evenly sprinkle the crushed product on the field, and spray the dry powder preparation of pest-resistant microorganisms on the field at the same time;

[0087] 5) Use a tractor with no less than 90 horsep...

Embodiment 3

[0098] The method for returning livestock and poultry manure to fields by spraying straw powder, is characterized in that it includes the following steps:

[0099] 1) While harvesting the corn with a corn combine harvester, crush the corn stalks to a length ≤ 10 cm, and evenly scatter them in the field;

[0100] 2) Gather the corn stalks scattered on the 8 ridges in the middle 2 ridges by using the tractor towed finger-disc rake;

[0101] 3) Take the livestock and poultry manure stored in the oxidation pond of the farm, add a decomposing microbial preparation to it at a ratio of 0.1% w / w, stir evenly, and then evenly spray the mixture on the straw surface;

[0102] 4) After the manure on the surface of the straw is naturally air-dried, crush it to a length of 2 to 5 cm, then evenly sprinkle the crushed product on the field, and spray the dry powder preparation of pest-resistant microorganisms on the field at the same time;

[0103] 5) Use a tractor with no less than 55 horsep...

Abstract

The invention provides a straw crushing and returning method by spraying livestock and poultry manure. According to the technical scheme, after corns grow to a full ripe stage, harvesting is carried out by using a corn combine harvester, corn straw is coarsely crushed simultaneously, and then the crushed corn straw is thrown into a field. Livestock and poultry manure is mixed with decomposition microorganisms and then is sprayed to straw surfaces, further crushing is carried out after the livestock and poultry manure is naturally air-dried, the crushed straw mixed with the livestock and poultry manure is uniformly thrown into the field along with the advancing of a tractor, meanwhile, an anti-disease and disease-resistant microbial dry powder preparation is sprayed into the field, and thestraw mixed with the manure is uniformly distributed in the tillage layer through rotary tillage or overturning, so that the whole returning process is completed. According to the method disclosed bythe invention, livestock and poultry manure and straw can be massively eliminated, the content of organic matter and nutrients in soil can be improved, the soil structure and the soil moisture contentare improved, soil fertility is promoted, and sustainable utilization of black soil resources is realized. Meanwhile, the method is simple and convenient to operate, is easy to implement and is low in cost, and therefore, the method has an outstanding promotion prospect.

Description

technical field [0001] The invention relates to the technical field of agricultural production, and further relates to the recycling of agricultural waste and a method for returning straws to fields, and in particular to a method for returning field straw powder by spraying livestock and poultry manure. Background technique [0002] Livestock and poultry manure and corn stalks are wastes produced in large quantities along with agricultural production. Taking Jilin Province as an example, about 67 million tons of livestock and poultry manure and 50 million tons of corn stalks are produced every year. Affected by farming patterns and lifestyles, these resources are completely in a state of high consumption, high pollution, and low output. As of the end of 2017, the comprehensive utilization rate of livestock and poultry manure in Jilin Province was about 67%, and the comprehensive utilization rate of straw reached 75%. There are still quite a lot of livestock and poultry manur...
