Embodiment 1

[0024] The present embodiment provides a method for returning rice straws to the field after fast rot, comprising the following steps:

[0025] (1) Chop the rice straws into short straws with a length of less than 20cm, and lay the short straw layers into piles, the thickness of a single layer is 30cm, the number of layers is 4, and the water content of the short straws can reach 65-70% by spraying water on each layer. At the same time, the microbial starter is sprinkled on the short rod, and the addition amount of the microbial fermentation agent is 4% of the weight of the short rod, and compost fermentation is carried out; , 6 parts of brown sugar; Described microbial mixed microbial inoculum is made up of 4 parts by weight of Bacillus subtilis, 8 parts of Trichoderma konzei, 6 parts of white rot fungi, and 5 parts of Aspergillus niger;

[0026] (2) When the compost fermentation process is carried out for 15 days, the stacked fermentation short rods are turned over, and the ...

Embodiment 2

[0029] The present embodiment provides a method for returning rice straws to the field after fast rot, comprising the following steps:

[0030] (1) Chop the rice straws into short straws with a length of less than 20 cm, and lay the short straw layers into piles, the thickness of a single layer is 40 cm, the number of layers is 4, and the water content of the short straws can reach 65-70% by spraying water on each layer. At the same time, the microbial starter is sprinkled on the short rod, and the addition amount of the microbial fermentation agent is 5% of the weight of the short rod, and compost fermentation is carried out; , 5 parts of brown sugar; Described microbial mixed microbial inoculum is made up of 3 parts by weight of Bacillus subtilis, 6 parts of Trichoderma konzei, 5 parts of white rot fungus, 6 parts of Aspergillus niger;

[0031] (2) when the compost fermentation treatment is carried out for 15 days, the stacked fermentation short rods are turned over, and the...

Abstract

The invention relates to the technical field of agricultural waste treatment, and specifically discloses a method for returning rice stalks to the field after fast decay. When the composting process reaches 60~70%, the microbial starter is sprinkled on the short rods for composting fermentation; when the composting fermentation process is carried out for 10~15 days, the piled fermentation short rods are turned over, and the surface of the fermentation short rods is placed on the surface of the fermentation short rods during the turning process. Spray the oxalic acid solution to mix well, and then continue to ferment for 30 to 40 days to obtain the decomposed rice straw organic fertilizer; sprinkle the decomposed rice straw organic fertilizer on the surface of the field, and then rotate it into the soil to complete the return of the rice straw to the field. In the method for returning the rice straw to the field by fast rot of the present invention, a variety of bacterial agents are used to cooperate with the fermented rice straw, which greatly shortens the fermentation and decomposition time of the rice straw, realizes the fast rot of the rice straw and returns to the field. In the field, improving the soil fertility of the field can be used as a fertilizer source for the next season of rice crops, reducing the application amount of chemical fertilizers and improving the yield and quality of rice.

Description

technical field [0001] The invention belongs to the technical field of agricultural waste treatment, and in particular relates to a method for returning rice straws to the field after fast rot. Background technique [0002] With the acceleration of the development of modern agriculture, the pressure on agricultural resources and the environment has also increased accordingly. The deterioration of the ecological environment and the high resource consumption mode of production have become the shackles of my country's sustainable social and economic development, especially the intensification and scale of modern agriculture. The development of agricultural waste has resulted in the accumulation of a large amount of agricultural waste, which has resulted in more serious environmental problems and resource waste. Crop straw is an important biological resource, and straw is rich in nutrients such as nitrogen, phosphorus, potassium and organic matter, and is an underutilized agricul...
