Problems solved by technology

[0006] In the prior art, direct rot is generally used for straw and incineration is still used in remote areas. The use of incineration will cause environmental pollution and is prohibited in the current environment. Secondly, if the rot is ignored, the rot cycle will be longer, and the rot will still be incomplete. Affect the follow-up rice transplanting work

Embodiment 1

[0023] see figure 1 , the present invention provides a technical solution for the use of microorganisms in rice straw returning to the field in Northeast China: the technology for using microorganisms in returning rice straw to the field in Northeast China includes the following steps:

[0024] S1: Straw Harvesting: Harvesting and straw processing; early rice is harvested mechanically. After harvesting and threshing the whole stalk less than 15 centimeters from the field surface, the straw is spread evenly in situ, and the straw is not piled up; if necessary, beat the straw with a stick , so that the straw is in good contact with the soil; the harvesting machine is a large harvester for early rice harvesting.

[0025] S2: Addition of fertilizer and decomposing agent: While returning rice straw to the field, apply appropriate amount of nitrogen fertilizer, 5-10 kg of urea per mu to adjust the carbon-nitrogen ratio; and add 2 kg of self-prepared biological compound bacterial dec...

Embodiment 2

[0028] The invention provides a technical solution for the utilization of microorganisms in rice straw returning to the field in the Northeast region: the utilization technology of microorganisms in the returning of rice straw in the Northeast region,

[0029] Straw retting pile:

[0030] 1) Self-prepared biological compound decomposing agent 2 kg, urea 2 kg, brown sugar 5 kg, etc., add water and stir to fully dissolve, and prepare mother liquor.

[0031] 3) Spread 700 kg of straw beside the corner of the field, each layer is 20 cm thick, and mix the mother liquor with water to spray evenly on the straw until the straw is soaked, sharing 400 kg of water.

[0032] The pile should be turned once every 15-20 days. The straw in the four corners is not rotten. Put the straw in the middle and spray it with water.

Abstract

The invention discloses a microorganism utilization technology for returning straw to a field in the northeast region. The technology comprises the following steps: harvesting and straw treatment arecarried out; early rice is harvested mechanically, whole stems of rice plants about 15 cm below the surface of a field are harvested and threshed, all straw is directly and uniformly spread in situ, and straw piling is avoided; when necessary, the straw is beaten by a stick to make better contact with soil; during returning the straw to the field, nitrogen fertilizer is applied properly, and 5-10kg of urea is applied per mu to adjust the carbon-nitrogen ratio; 2 kg of a self-prepared biological composite bacterium decomposing agent to accelerate decomposition of straw, and about 15 kg of limeis applied per mu; after returning the straw to the field, the field is irrigated with water for 10 cm to immerse straw surfaces for fear that the straw loses water and cannot rot and decompose easily, after the field is soaked for 7 days, rice seedling transplantation can be carried out after turning and burning are performed, during rice seedling transplantation, 3 cm of shallow water is retained in the field, and water is drained to air the field in a tillering period. The microorganism utilization technology can return the straw to the field quickly to achieve the purpose of returning thestraw to the field by microorganisms.

Description

technical field [0001] The invention relates to the technical field of straw returning to the field, in particular to the utilization technology of microorganisms for returning rice straw to the field in Northeast China. Background technique [0002] Straw returning to the field is a measure of fertilizing soil fertility and increasing production that is generally valued in the world today. It can increase fertilizer and increase production while eliminating the air pollution caused by straw burning. Straw returning can increase soil organic matter, improve soil structure, loosen soil, increase porosity, reduce capacity, and promote microbial activity and root development of crops. Straw returning to the field has a significant effect on increasing fertilizer and production, and generally can increase production by 5% to 10%. However, if the method is not appropriate, it will also lead to an increase in soil pathogens, aggravation of crop diseases, and lack of seedlings (sic...
