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 fertilizer is too high, and the benefit is not enough to cover the cost of fertilization, so the utilization of straw fertilizer cannot continue
[0004] Using straw to process biochar, firstly, the grade of biochar is not enough, the market prospect is not good, the amount of utilization as charcoal-based fertilizer is too little, which is equivalent to fertilizer "monosodium glutamate", and the market capacity of biochar is not enough to digest the output of straw

Abstract

The invention discloses a commercial method for rapid on-site humification of straw and returning to the field, comprising: information collection, scheme design of rapid straw humification, on-site operation, fertilization scheme after repeated operations, and a complete database. On-site operations include straw collection, crushing, batching, pre-wetting, regular throwing, straw humus detection, straw humus throwing back to the field, and soil improvement. The high-nutrition primer used in the batching and pre-wetting process includes the following steps: preparation of medium raw materials, preparation of medium, inoculation of complex bacterial agents, aerobic fermentation, detection of organic matter, water-soluble organic matter, and number of viable bacteria. The invention designs a straw humus application scheme according to the law of crop nutrition requirements, and realizes the recycling of agricultural waste straw, improvement of soil fertility and sustainable development of agriculture. The present invention has standardized operating procedures for information collection, straw rapid humification scheme design, on-site operation and subsequent repeated operations, and realizes the commercial application of on-site rapid humification of straw.

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...
