Serial products formed by the fertilizer have special specificity, selectivity and one-time fertilization in an annual growth cycle to fruit trees, paddy rice, maize, etc., so that the yield increasing rate of crops can reach more than 10%, and the fertilizer has both a fertilizer effect and a drug effect to paddy rice.
Description
The present invention relates to a kind of new durable composite fertilizer and produce the method for this composite fertilizer.
The development of our times various countries chemical fertilizer enters the new stage.Various countries scholar and chemical enterprise man introduce coating, biostats chemical fertilizer industry as " frontier technology ", and produce in succession such as coating, biostats fertilizer.But, these fertilizer complex process, cost height, environmental effect is not good enough, as the formulation of controlled availability fertilizer, is not desirable, and " coating and the biostats " selected for use also is not to belong to " frontier technology ".Do not see the appearance of novel form durable composite fertilizer both at home and abroad on the chemical fertilizer market yet.Looking into novel material according to international online and show, verify organic additive---yellow humic acid series product at home and abroad first, is different to the effect of soil, plant body enzyme system.Wherein the yellow humic acid component has restraining effect to soil urease, 10% yellow humic acid component add-on, after cultivating 10 days, to the inhibiting rate of urea substrate up to 99.88%; The salt component is planted in yellow corruption, and 100ppm concentration is cultivated seedling root of hair effect to Malus spectabilis, and full-bloom stage Guoguang apple pollen germination rate or the like has bigger activation effect.And this activation and restraining effect are applied to chemical fertilizer industry production, and this is an important breakthrough.
Scholar both domestic and external and chemical enterprise man are at the technical formula of exerting the chemical fertilizer of seeking efficient, multi-functional, compoundization.Many countries such as America and Europe and Japan produce (SCU) " sulfur coated urea ", (PCU) " silica polymkeric substance---coat urea ", plastics, sulfur coating crust material or the like in succession.Domestic also have (CP) nitrobacteria inhibitor, (PPD) benzenephosphonic acid diamide salt---and urease inhibitorses etc. are the long-acting N fertilizer of additive.At home and abroad large fertilizer product is binary or ternary chemical fertilizer on the chemical fertilizer market, and these fertilizer are that molecule is compound or blend together compound manure basically.
Coating and biostats fertilizer, not only nutrient, composition are single, and cost height, complex process, environmental effect is not good enough, are not desirable as the formulation of controlled availability fertilizer.Even if, changed, but still belong to chemical fertilizer, also claim " exposed crust material " though the nutrient composition is compound from the binary or the Nitrogen, Phosphorus and Potassium of the U.S., Italy, Sweden's import.This fertilizer not only utilization ratio is low, and long-term application is the destruction that progressive, a tired collection is given birth to soil " fertility storehouse ".Especially simple substance crust material is through secondary processing, and economical character is not seen improvement, and reverse side has improved cost, increased the weight of peasant's burden.
