Abstract

The invention discloses a fertilizer capable of increasing the silicon content in paddy soil. The fertilizer is prepared from, by weight, 90-100 parts of ammonium sulfate, 40-50 parts of sodium nitrate, 15-25 parts of defluorinated phosphate fertilizer, 10-16 parts of potassium polyphosphate, 40-60 parts of potassium nitrate, 85-95 parts of organic fertilizer, 6-12 parts of kieselguhr, 2-4 parts of borax, 0.2-0.4 part of iron(III)-urea complex, 0.2-0.4 part of zinc sulfate, 0.3-0.5 part of manganese nitrate, 0.2-0.4 part of diethylaminoethyl hexanoate and 14-16 parts of adhesive. The adhesiveis prepared from, by weight, 8-16 parts of compound coating agent and 2-5 parts of zeolite powder. The preparation process of the compound coating agent includes the steps that a whey protein solutionand a casein solution are evenly mixed, the pH value of the system is regulated, the temperature is raised, stirring is carried out, transglutaminase is added, stirring continues, inactivation is carried out, glycerin and microcrystalline cellulose are added, and the mixture is stirred to be uniform to obtain the compound coating agent.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer for supplementing the silicon content of paddy soil. Background technique [0002] Rice is the most important food crop in my country. Studies have shown that every 100kg of rice grains need to absorb 22kg of silicon, which is 4.4 times the sum of nitrogen, phosphorus and potassium. High-yield rice can take away SiO from the soil in one growing season. 2 75-130kg / mu. SiO in soil 2 The content is very high, but the effective silicon that can be used by plants is only 50-250mg / kg. Moreover, with the continuous improvement of rice production level and the extension of the continuous planting time, the silicon in the paddy soil is constantly decreasing. If the rice is deficient in silicon during the growth and development process, it will show leaf drooping at the seedling stage, resulting in premature rice senescence in the later stage. Insufficient grain fillin...
