Problems solved by technology

[0003] With the use of conventional organic fertilizers, the straw is bundled, transported to the factory and then crushed. First, the transportation cost is high, the processing is difficult, and the factory occupies a large area. Second, it is difficult to obtain approval for land and environmental protection procedures, all of which have increased The cost of production and use of organic fertilizer, for field crops, the cost of applying organic fertil

Abstract

The invention discloses a commercial method for quickly humifying and returning straws to a field on site. The method includes the steps of information collection, straw rapid humification scheme design, field operation, a fertilization scheme after repeated operation, and database improvement. The field operation includes the steps of straw collection, smashing, burdening, pre-wetting, regular turning and throwing, straw humus detection, straw humus throwing and returning to the field, and soil improvement. A high-nutrition initiator used in the burdening and the pre-wetting processes is prepared by the following steps of preparing culture medium raw materials, preparing a culture medium, inoculating a complex microbial inoculant, performing aerobic fermentation, and detecting organic matters, water-soluble organic matters and viable count. According to the commercial method for quickly humifying and returning the straws to the field on site, a straw humus application scheme is designed according to the nutrient requirement law of crops, so that agricultural waste straw cyclic utilization, soil fertility improvement, and agricultural sustainable development are achieved. Standardized operation regulations are provided for information collection, straw rapid humification scheme design, field operation and subsequent repeated operation, so that commercial application of straw in-situ rapid humification and returning to the field is achieved.

Description

technical field [0001] The invention relates to the technical field of resource utilization of agricultural waste and environmental protection, in particular to a commercial method for quickly humifying and returning straws to fields on site. Background technique [0002] After the crops are harvested, how to deal with a large amount of straw has always been a headache for the government and farmers. Straw littering will cause environmental and water pollution. In the past, farmers often burned straw on the spot, but it seriously polluted the air, and the country has explicitly banned straw burning. At present, straw utilization can be roughly divided into raw material utilization, fuel utilization, base material utilization, feed utilization, and fertilizer utilization. Raw material utilization, fuel utilization, base material utilization, and feed utilization, the utilization of straw is limited and the use cost is high. Among the various utilization methods of straw, t...
