Production process of special fertilizer organic for corns

Abstract

The invention provides a production process of an organic fertilizer special for corns. The organic fertilizer special for the corns is prepared by fermenting corn straws, cacti, shells and animal faces by virtue of biological bacteria, then treating by using earthworms, breaking the obtained earthworm faces into pieces with valerians, mixing with blumea balsamifera, and performing fermentation. According to the production process provided by the invention, the corn straws are adopted as the main raw material for the organic fertilizer special for the corns, and are subjected to a series of treatments by using the biological bacteria and the earthworms to ensure that the elements in the corn straws are converted into chemical state elements which can be easily absorbed by plants, and meanwhile, the elements and content thereof in the corn straws are similar to the elements and demands thereof required by the growth of the corns, so that the organic fertilizer can meet the requirements for the growth of the corns; and meanwhile, the organic matters in the process are subjected to two times of fermentation and one time of earthworm digestion, so that the formed organic matters are high in quality, can be dissolved in soil easily and absorbed by the plants easily, and can promote the aggregate structure of the soil and improve the permeability, water retention property and fertility retention property of the soil, therefore, the problem of land hardening is fundamentally solved, and continuous corn planting can be performed.

Description

technical field [0001] The invention belongs to a production process of organic fertilizer, in particular to a production process of special organic fertilizer for corn. Background technique [0002] Corn is the main food crop in my country. Corn needs a large amount of fertilizer. Scientific and rational fertilization is an important aspect of high-quality, high-yield, and efficient development of corn production. After ordinary fertilizers are applied to the soil, due to the short fertilizer effect period, topdressing is required in the later stage. The use of resin-coated fertilizers can prolong the fertilizer effect period, and the effect of topdressing is not needed in the later stage. However, when the rain is heavy, the resin-coated fertilizers will speed up the dissolution and cannot achieve the effect of controlled release. Just because of this, the urea added with urease inhibitor and nitrification inhibitor in the present invention can overcome the shortcoming of ...

Problems solved by technology

[0003] At the same time, the spring corn area in my country generally starts to sow at the end of April and harvests in October, with an average yield of 500 kilograms. However, with the increase in fertilization in recent years, although the yield has increased, the soil fertility has declined at the same time, the soil has hardened, and the bottom of the plow is getting worse. It is getting shallower and the corn lodging is very serious in the late stage. Although the country strongly advocates the use of organic fertilizers to improve the soil and improve the soil plow layer environment, but because organic fertilizers are more troublesome to use, the amount of application is large, and the labor input cost is too high, so now farmers They are unwilling to use organic fertilizers, so farmers now use a large amount of inorganic fertilizers. It is precisely because of the extensive use of inorganic fertilizers that the soil is compacted and the soil structure is destroyed.
