Problems solved by technology

[0002] Corn is an important economic crop in my country, and the input of fertilizer plays a vital role in the yield of corn. However, in the actual planting process of corn, there have been problems of single and excessive fertilization for a long time, and the average utilization of fertilizer The rate is very low, the main reason is that the fertilizer is quick-acting and volatile and easy to lose
The corresponding measures are to use slow-release coated fertilizers to improve the utilization rate of nutrients, but the strength of the single-layer coating is low, the proportion of slow-release nutrients is fixed, and it is not targeted, and does not meet the constraints of crops' nutrient requirements in different periods. own development

Abstract

The invention discloses corn-used slow-release fertilizer synergist for optimizing soil micro-ecological environment. The fertilizer synergist is composed of, by weight, 8-10 parts of potassium chloride, 2-4 parts of active carbon powder, 1-2 parts of potassium iodide, 23-24 parts of hemp seed powder, 10-14 parts of soybean oil, 18-22 parts of soy sauce residue, 12-16 parts of ammonium bicarbonate, 2-4 parts of slow-release microbial zones, 4-5 parts of slow-release microelement chelation layers, 6-9 parts of slow-release sitallization powdered rock phosphate coating layers and a defined amount of water. After the corn-used fertilizer synergist is used, the soil microbial activity is strengthened remarkably, the utilization rate to nutrients in ordinary fertilizer by the corn is improved, in addition, it is further facilitated to improve the soil quality, by adding various types of natural organic matters such as the soy sauce residue and the soybean oil, the amount and diversity of soil microorganisms are further increased, the healthy development of the soil ecological system is facilitated, and an excellent soil environment is provided for the growth of the corn.
