Abstract
The invention discloses high-nutrient-utilization slow-release fertilizer synergist used for corn. The fertilizer synergist comprises, by weight, 3-5 parts of ammonium bicarbonate, 1-3 parts of copper sulfate, 16-18 parts of ammonuim humate, 10-13 parts of nidus vespae, 7-10 parts of zeolite powder, 26-29 parts of sweet potato waste, 9-10 parts of guar gum powder, 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. According to the fertilizer synergist used for the corn, by means of multiple layers of coating and drying as well as mixing and adding of organic materials and mineral substances, porous structures are formed inside the synergist, after the synergist is mixed with fertilizer and fertilized, the water, nitrogen, phosphorus and potassium in the soil can enter capillary tubes of porous frames, so that the substances in the soil are easy for the corn to absorb, and the substances in the capillary tubes are released gradually through slow-release layers of the synergist for being utilized by the growth of the corn.
Description
Technical field
The present invention relates to a kind of fertilizer synergist technical field, particularly a kind of corn slow release fertilizer synergistic agent of high plant recovery of nutrient and preparation method thereof.
Background technology
Corn is a kind of important cash crop of China, and the output of the input of fertilizer to corn serves vital effect, but in the actual planting process of corn, long-term existence the problem of apply fertilizer single and excessive fertilization, the average utilization of fertilizer is very low, and its major cause is the quick-acting of fertilizer and volatile fugitive volatile.The measure that correspondence is taked is then use release-controlled coated fertilizer to improve the utilization ratio of nutrient, but individual layer bag film strength is low, and slowly-releasing nutrients ratio is fixed, and without specific aim, does not meet the development that the demand etc. of crop different times to nutrient constrains self.
Current inventor provides the fertilizer synergist that a kind of corn planting uses for this reason, coated by different three layers of slow release layer, the corresponding seedling stage of corn growth, vegetative period and three periods of ripening stage, collocation common fertilizer uses the regulation of fertilizer requirement that fully can meet corn, not only improve the utilising efficiency of fertilizer, reach fertilizer and need fertile balance, improveing the physico-chemical property of planting soil, for the stable high yield of corn provides sound assurance simultaneously.
Summary of the invention
The present invention compensate for the deficiencies in the prior art, provides slow release fertilizer synergistic agent of the high plant recovery of nutrient of a kind of corn and preparation method thereof.
