Problems solved by technology

Excessive fertilizers will seep into the shallow groundwater within 20m, so that the application of chemical fertilizers with nitric acid in the groundwater will also affect the structure of the soil. Studies have shown that my country consumes 50 million tons of chemical fertilizers for nutrient resources every year, accounting for 27% of the world's total consumption of chemical fertilizers. %, while my country's arable land only accounts for 7% of the world's total arable land, the utilization rate of chemical nitrogen fertilizer is only 30%, and the loss rate is as high as 60%, which greatly consumes non-renewable resources (coal, natural gas) used for fertilizer production

Embodiment 1

[0024] A method for utilizing straw composting, comprising the steps of:

[0025] (1) crushing the stalks into stalk particles with a particle diameter of 3 mm;

[0026] (2) Mix straw granules with soil, livestock dung, and human excrement in a ratio of 7:1:2:1, and place the mixture in airtight conditions at 25°C for 24 hours to obtain pretreated straw granules;

[0027] (3) mixing the pretreated straw granules obtained in step (2) with solid bacterial agents and beer grains to obtain compost raw materials;

[0028] (4) Compost the compost raw materials into a fermentation pile, and ferment them outdoors for 25-30 days. During the composting process, add a certain amount of ammonium bicarbonate to the compost raw materials so that the carbon-ammonia ratio is 25:1, increasing the carbon-ammonia The purpose of the ratio is to promote the decomposition activity of microorganisms during the fermentation process. And turn over the fermentation pile every 7 days. The function of ...

Embodiment 2

[0035] The technical problem to be solved by the present invention adopts the following technical solutions to realize:

[0036] A method for utilizing straw composting, comprising the steps of:

[0037] (1) crushing the stalks into straw granules with a particle diameter of 6 mm;

[0038] (2) Mix straw granules with soil, livestock dung, and human excrement in a ratio of 7:1:2:1, and place the mixture in airtight conditions at 30°C for 36 hours to obtain pretreated straw granules;

[0039] (3) mixing the pretreated straw granules obtained in step (2) with solid bacterial agents and beer grains to obtain compost raw materials;

[0040] (4) Compost the compost raw materials into fermentation stacks and ferment them outdoors for 30 days. During the composting process, add a certain amount of ammonium bicarbonate to the compost raw materials so that the carbon-ammonia ratio is 25:1 and increase the carbon-ammonia ratio The purpose is to promote the decomposition activity of mic...

Embodiment 3

[0047] The technical problem to be solved by the present invention adopts the following technical solutions to realize:

[0048] A method for utilizing straw composting, comprising the steps of:

[0049] (1) crushing the stalks into stalk particles with a particle diameter of 5 mm;

Abstract

The invention relates to the field of plant straw reutilization, in particular to a method for compositing by utilizing straw. The method comprises the following steps: (1) crushing straw into straw particles; (2) mixing the straw particles, soil, animal manure and human excreta to obtain pre-treated straw particles; (3) mixing the pre-treated straw particles, solid inoculants and brewer grains to obtain compost raw materials; (4) stacking the compost raw materials into a fermenting stack. According to the method for composting by utilizing the straw, resources can be fully saved, reasonable utilization of the resources is realized, and the cost is relatively low; during a composting process, a certain amount of ammonium bicarbonate is added, so that the composting time of the straw can be effectively shortened. The bio-fertilizer obtained by the method has high content of N, P and K, and is beneficial to the growth of crops.

Description

technical field [0001] The invention relates to the field of plant stalk reuse, in particular to a method for utilizing stalks for composting. Background technique [0002] The fertilizers currently used in my country's agriculture are mainly chemical fertilizers and organic fertilizers. Chemical fertilizers are mainly divided into simple fertilizers, compound fertilizers, and slow-control fertilizers. Organic fertilizers mainly include commercial organic fertilizers, commercial organic-inorganic compound fertilizers, commercial microbial compound fertilizers, and commercial microbial organic fertilizers. Fertilizer, organic and inorganic biological fertilizer. Because chemical fertilizers can make crops grow faster in a short period of time, farmers in our country generally rely on chemical fertilizers. With the increase of farmers' investment in farming, the phenomenon of "excessive fertilization, increasing production but not increasing income" in rural areas is also incr...
