Problems solved by technology

[0007] The present invention aims to solve the problem that in the straw degradation process in the prior art, the straw is difficult to be decomposed by microorganisms in the natural state due to its high C / N, and the temperature in the northern region is low, so the straw is difficult to decompose, resulting in the straw being decomposed in the soil after returning to the field The cycle of decomposition and transformation is long, and it is difficult to use it as a fertilizer source for crops in the current season

Embodiment 1

[0035] A method for returning corn stalks to the field, the steps are as follows:

[0036] (1) After the corn is harvested, collect the stalks and crush them into 10cm segments while they are green;

[0037] (2) Dig a cellar in the harvested corn field, the length of the cellar is 2m, the width is 2m, and the depth is 1m, and the excavated soil is used for future use.

[0038](3) Put the straw yards processed in step (1) into the cellar, and dilute the biological agent with 10 times of water 24 hours in advance (it is beneficial to restore and enhance the vitality and activity of the bacteria, and improve the efficiency of the decomposing agent to decompose the straw) to obtain the dilution Activation solution, add diluted activation solution according to 20% of the straw weight, mix evenly, ferment at room temperature, check the temperature of the fermented product during the fermentation process, when the temperature rises above 60°C, turn the mixed material, and then turn i...

Embodiment 2

[0053] A method for returning straw to the field, the steps are as follows:

[0054] (1) After the corn is harvested, collect the stalks and crush them into 20cm segments while they are green;

[0055] (2) Dig a cellar in the harvested corn field, the length of the cellar is 3m, the width is 2m, and the depth is 2m, and the excavated soil is used for future use.

[0056] (3) Put the straw yards processed in step (1) into the cellar, and dilute the biological agent with 10 times of water 24 hours in advance (it is beneficial to restore and enhance the vitality and activity of the bacteria, and improve the efficiency of the decomposing agent to decompose the straw) to obtain the dilution Activation solution, add diluted activation solution according to 30% of the straw weight, mix well, ferment at room temperature, check the temperature of the fermented product during the fermentation process, when the temperature rises above 60°C, turn the mixed material, and then turn it every...

Embodiment 3

[0070] Example 3: Effects of returning crop straws to the plow layer soil

[0071] The method of returning corn stalks to the field in Example 1-2 is used to improve soil fertility. When the corn stalks are mechanically returned to the field, the application rate of corn stalks is 300kg / mu, and the plow layer soil before the test and after 1 year of the test is collected respectively, and analyzed. The basic physical and chemical values, the specific results are shown in Table 1:

[0072] Table 1 Effects of straw returning methods on soil

[0073] Organic matter (g / kg) Total nitrogen (g / kg) Phosphorus (g / kg) Potassium (g / kg) Bulk density (g / cm 3 )

[0074] It can be seen from Table 1 that after adopting the method of returning corn stalks to the field in Example 1-2, the physical and chemical properties of the soil have been greatly changed. Soil bulk density increases soil porosity. However, when corn stalks are returned to the field mechanically, the ...

Abstract

The invention provides a biological preparation for treating crop straw. The biological preparation is prepared from complex microbial agents and auxiliaries according to a proportion of 1-2:3-5. Fermentation cytophaga, alcaligenes faecalis, paracoccus denitrificans, bacillus pumilus, phanerochaete chrysosporium and actinomycetes are mixed with one another according to a volume ratio of 5:4:2:6:1:3 to obtain the complex microbial agents. The biological preparation has the advantages that the problems of tight crop rotation between two seasons of crops due to the fact that all straw returns to fields locally, difficulty in carrying out cuttage and seed sowing on next-stubble crops, yellowing and seedling weakness due to nitrogen fighting between seedlings and straw decomposition and the like can be effectively solved by the aid of the biological preparation; the straw can return to fields locally, and the biological preparation can be widely applied to returning the crop straw of rice, wheat, corn and the like to the fields.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and relates to a biological agent for treating crop straws. The bacterial agent is suitable for returning the crop straws to the field when they are decomposed. Background technique [0002] Chinese farmers have a long history of using crop stalks, but due to the low level of agricultural production and low output in the past, the amount of stalks was small. Except for a small amount of straw used for gaskets, feeding livestock, and some used for composting, most of the straw was used as fuel. Lost. With the development of agricultural production, since the 1980s, China's grain output has increased significantly, and the amount of straw has also increased. In addition, the promotion of firewood-saving and coal-saving technologies, the popularization of coal burning and the use of liquefied petroleum gas have resulted in a large amount of surplus straw in rural areas. . At the same time...
