Abstract
The invention discloses a slow-release fertilizer synergist for improving the tolerance to alkaline soil of corn and a preparation method of the slow-release fertilizer synergist. The slow-release fertilizer synergist is prepared from the following raw materials in parts by weight: 9-11 parts of monoammonium phosphate, 1-2 parts of sulfur powder, 3-4 parts of calcium carbonate powder, 20-24 parts of peat, 29-31 parts of dried cow manure, 17-18 parts of wheat bran, 16-18 parts of acidic weathered coal, 2-4 parts of a slow-release biological layer, 4-5 parts of a slow-release microelement chelated layer, 6-9 parts of a slow-release micro-crystallized phosphate rock powder coating layer and a defined amount of water. The slow-release fertilizer synergist has the advantages that a lot of slightly acidic components are added into the raw materials to neutralize the pH value of soil, and a lot of organic components are also added, so that the organic matter content of the soil is increased in a slow-release process, both improvement of the soil buffering property and maintenance of the acid-alkali relatively stable state of the soil are well facilitated, the corn can still grow normally in the alkaline soil with the stable yield. Therefore, the slow-release fertilizer synergist is suitable for popularization and utilization in alkaline soil regions.
Description
Technical field
The present invention relates to a kind of fertilizer synergist technical field, particularly a kind of corn that improves is to slow release fertilizer synergistic agent of alkaline soil tolerance 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 a kind of corn that improves to slow release fertilizer synergistic agent of alkaline soil tolerance and preparation method thereof.

(4) by SULPHUR POWDER and Paris white levigate after add a small amount of water even application in step 3 gained particle exterior surface, then slowly-releasing microbial layer and remaining component are mixed and add the spraying of a small amount of water and be wrapped in outside particle, form the skin of synergistic agent;
(5) air-dry with gas blower at step 4 gained particle being placed in 35-45 DEG C, weighing and bagging is placed on dry place and preserves.
The using method of synergistic agent of the present invention is be manured into soil after mixing according to the ratio of 8%-10% and common fertilizer.
Beneficial effect of the present invention:
Its adsorptive power to microorganism can be increased to diatomaceous modification in slowly-releasing microbial layer, stable in properties, extends working time simultaneously, and to soil and microorganism toxicological harmless effect, beneficial microorganism activity can improve joins nutrient availability in fertilise, increases the utilization ratio of fertilizer.
The stability of the high viscosity performance guarantee synergistic agent particle of cow glue by adding in slowly-releasing micritization ground phosphate rock coating layer, simultaneously when after the outer composition of layer release of synergistic agent, internal layer is met water and can progressively be decomposed, and improve sustained release performance, and the interpolation of micritization ground phosphate rock can to the NH of internal layer
4 +-N plays good slow releasing function, for the heavy demand of corn ripening stage to nutrient provides support.
Corn fertilizer synergist of the present invention adds a large amount of slant acidity composition in the feed with sweetening of the soil pH value, with the addition of a large amount of organic composition simultaneously, the content of soil with organic matter is improve in slowly-releasing process, good promoter action is had for the shock-absorbing capacity, the metastable state of maintenance soil acid-base that promote soil, make corn in alkaline soils still can normal growth, and keep stable output, be suitable for soil promoting the use of in alkalescence area.
