Field biological straw composting method for protecting and improving black soil lands

Abstract

The invention discloses a field biological straw composting method for protecting and improving black soil lands, which belongs to the technical field of biofertilizers. According to the method, horizontal rotation type continuous biological fermentation equipment is arranged in the field, a straw decomposition agent and livestock and poultry excrement are inputted into the horizontal rotation type continuous biological fermentation equipment, the straw decomposition agent and the livestock and poultry excrement are uniformly mixed by the horizontal rotation type continuous biological fermentation equipment and then kept still for static fermentation, and after static fermentation is completed, microbe-enriched compost for decomposing straw is obtained and outputted ready for later use; apile is built layer by layer, and after pile building is completed, decomposition and fermentation are carried out under the natural environment, so that straw fertilizer is obtained. The method disclosed by the invention can treat straw in a large amount on the site, nearby, in time and quickly, the obtained straw fertilizer can be directly returned into fields, increase the quantity of effective microbial communities in soil, enhance soil activity, restore crop nutrients and increase the content of soil organic matter, and after being applied in successive years, the straw fertilizer can achieve the objective of protecting the quality of black soil lands and increasing soil fertility.

Description

technical field

[0001] The invention relates to a method for field straw biological composting for black soil protection and promotion, and belongs to the technical field of biological fertilizers. Background technique

[0002] Black soil is an extremely precious natural resource. In recent years, the degradation of black soil in Northeast China has become increasingly prominent, and it is urgent to strengthen protection. The black soil cultivated land area in Heilongjiang Province accounts for 50.4% of the cultivated land area in the Northeast black soil region. Potassium content decreased by 20.1 mg / kg, the soil bulk density of the plow layer increased, the total amount of beneficial microorganisms in the soil decreased, and the activity also decreased greatly. Returning straw to field and adding organic fertilizer is one of the important measures to protect and improve soil fertility. Straw is the basic resource of organic fertilizer source. As my country's grain produ...

Examples

Embodiment 1

[0032] This example provides a method for field straw biocomposting for black soil protection and promotion. The horizontal rotary continuous biological fermentation equipment in this method is the horizontal rotary continuous biological fermentation equipment disclosed in the patent ZL 201710408863.6. The straw layer The fresh corn stalks are directly used, and the decomposing agent is the high-efficiency concentrated compound bacteria specially used for the decomposing of Yifuyuan straws (the total number of beneficial bacteria per gram is ≥ 50 billion CFU). The specific method is as follows:

[0033] 1. Preparation of microorganism-enriched compost for straw decomposing (activation of flora, logarithmic proliferation (enrichment)), to produce microbial-enriched compost for straw decomposing, specific method:

[0034] (1) Set up horizontal rotary continuous biological fermentation equipment in the field, input the straw decomposing agent and livestock manure into the horizont...

Embodiment 2

[0048] The straw fertilizer obtained in Example 1 is used for returning to the field. The specific method is to evenly spread the straw fertilizer to the field at an application rate of 1 ton / mu in autumn to improve the organic matter of the black soil cultivated land. In this example, on October 25, 2017, the straw fertilizer obtained in Example 1 was scattered and returned to 600 mu of fields.
