Preparation method of organic-inorganic compound fertilizer with stable and long-lasting fertilizer efficiency

Abstract

The invention discloses a preparation method of an organic-inorganic compound fertilizer with stable and long-lasting fertilizer efficiency, which comprises the following steps: S1, mixing cow dung and chicken manure, evaporating water, adding black soil and compost, and fully mixing to obtain a mixture; s2, transferring the mixture to a fermentation workshop for fermentation, adding acetic acid, acid iron and bacillus licheniformis when the temperature of the material is reduced to below 45 DEG C and the water content is less than 40%, then carrying out coarse crushing and sieving, and carrying out aging fermentation on the screen underflow, so as to obtain an organic fertilizer; s3, mixing a nitrogen fertilizer synergist, an inorganic fertilizer and the organic fertilizer, drying, and keeping the moisture at 15-18%; and then adding a product into a granulator to prepare the organic-inorganic compound fertilizer. The organic-inorganic compound fertilizer is prepared by mixing an inorganic fertilizer and an organic fertilizer, does not cause soil hardening, can effectively improve the soil quality, is stable in fertilizer efficiency, and increases the product yield; the fertilizer is simple in raw materials, convenient to prepare, high in nutrient utilization rate, safe and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of preparation of compound fertilizers, and more specifically relates to a method for preparing organic-inorganic compound fertilizers with stable and long-lasting fertilizer effects. Background technique [0002] The status of fertilizer in agricultural production is very important, and it plays a pivotal role. In order to meet the needs of agricultural modernization, it is developing in the direction of high-efficiency compounding. With the development of facility agriculture (such as plastic greenhouses, etc.), the demand for fertilizers for vegetables and fruits will gradually increase. However, long-term and large-scale application of chemical fertilizers will break the agricultural ecological balance and lead to deterioration of soil properties and environmental pollution. For this reason, we propose a preparation method of organic-inorganic compound fertilizer with stable and long-lasting fertilizer ...
