Abstract
The invention which discloses a special slow release fertilizer for corn zinc power and a preparation method thereof relates to the technical field of slow release fertilizers. The preparation method which follows a nutrient absorption rule of corn comprises the following steps: burdening heated short grained urea, monoammonium phosphate, potassium chloride, chelated zinc, a urease inhibitor, a nitration inhibitor and bentonite according to a prescribed ratio, fusing urea at a high temperature, mixing, nozzle-granulating, cooling, screening, metering, and packaging. The special fertilizer has the advantages of reasonable nutrient distribution ratio, corn photosynthesis promotion, effective improvement of the absorption utilization rate of the fertilizer, and production cost saving.
Description
Technical field
The present invention relates to the slow-release fertilizer technical field, particularly relate to a kind of slow-release fertilizer that is used for corn and preparation method thereof.
Background technology
Corn is one of staple food crop of China, also is important fodder crop.The biological yield of corn is high, and fertilizer requirement is big, and scientific and reasonable fertilising is the importance of high yield, high-quality, high-efficient development Maize Production.Zinc is the essential nutrient of plant growth, and when corn lacked zinc, leaf photosynthesis weakened, and growth is suppressed, blade atrophy, distortion, and the attenuation of blade and blade meat tissue, mosaic disease very easily appears in minus green or albefaction between vein, influences crop yield.Scarce zinc has become the bottleneck of increasing crop yield and the global problem that crop yield improves.
At present, mainly there are following three problems in common slow-release fertilizer concerning corn:
1, can accomplish preferably that the fertilizer that delays to discharge costs an arm and a leg, be several times of common fertilizer, and common people are difficult to accept;
2, common slow release fertilizer lacks zinc element, causes crop to lack zinc easily, the influence growth;
3, common slow-release fertilizer nutrient element releasing rule can't match with the Maize Absorption rule, causes utilization rate of fertilizer low.
Summary of the invention
To the deficiency of prior art, the present invention provides a kind of corn zinc power special slow release fertilizer and preparation method thereof.
The present invention is accurately merged urea, monoammonium phosphate, Repone K, urease inhibitor, nitrification inhibitor, EDTA chelating zinc etc. according to the regulation of fertilizer requirement of corn, and it is fertile to form corn zinc power special slow release.This slow-release fertilizer not only nutrient absorption law of nutrient element releasing rule and corn matches, and has reduced fertilizer cost, makes the peasant be easy to accept.Adopt the single-dose application when corn seeding of this slow-release fertilizer simultaneously, no longer topdress later on, reduced labour cost.
Technical scheme of the present invention is following:
The fertile feed composition weight part of corn zinc power special slow release of the present invention is following:
Small particle urea 550-650 part,
Monoammonium phosphate 100-150 part,
Repone K 50-150 part,
EDTA chelating zinc 5-15 part,
Urease inhibitor 1-5 part,
Nitrification inhibitor 1-5 part,
Wilkinite 150-200 part;
Above-mentioned raw materials is the commercially available prod, wherein:
Nitrogen content is 46% in the small particle urea, and specification is 46-0-0;
Nitrogen content is 10% in the monoammonium phosphate, and phosphorus pentoxide content is 45%, and specification is 10-45-0;
Potassium oxide content is 60% in the Repone K, and specification is 0-0-60;
The content that relates in the above raw material is mass percent.
Corn zinc power special slow release of the present invention is fertile, and all raw materials particle diameter except that small particle urea is good less than 1mm all.
Corn zinc power special slow release of the present invention is fertile, and further preferred feed composition weight part is following:
Small particle urea 580-630 part,
Monoammonium phosphate 110-140 part,
Repone K 80-100 part,
EDTA chelating zinc 8-10 part,
Urease inhibitor 2-3 part,
Nitrification inhibitor 2-3 part,
Wilkinite 160-180 part.
Corn zinc power special slow release of the present invention is fertile, and most preferred feed composition weight part is following:
580 parts of small particle ureas,
140 parts of monoammonium phosphates,
100 parts in Repone K,
10 parts on EDTA chelating zinc,
2 parts of urease inhibitors,
2 parts of nitrification inhibitors,
166 parts of wilkinites.
The tower fused mass granulating technique production of the fertile employing of corn zinc power special slow release of the present invention; Its core technology is to utilize the suspended solid mixed slurry that forms the eutectic of good fluidity after urea melting liquid and the raw materials mix such as monoammonium phosphate, Repone K, EDTA chelating zinc, urease inhibitor, nitrification inhibitor by the prescription strict measurement; And pass through prilling spry; Mixed slurry is sprayed in the prilling tower; Make it in the process of gravity landing, carry out heat exchange with the airflow that rises, cooling curing forms particle, and metering packing gets final product after cooling, screening and anti-caking are handled again.
The application that corn zinc power special slow release of the present invention is fertile is that base manure once applies at the corn seeding previous crops, no longer imposes.
Advantage cheap, that nutrient is comprehensive, utilization rate of fertilizer is high that the present invention compared with prior art has:
1. nutrient is comprehensive, reasonable ratio
Product satisfies corn to nutrient demand in strict accordance with the regulation of fertilizer requirement and the soil nutrient characteristic scientific formula of corn growth, product nutrient distributing equilibrium, and nitrogenous proportioning is high, and nutrient is comprehensive, reasonable ratio;
2. the interpolation zinc element promotes photosynthesis, improves resistance
Corn is that zinc is participated in the formation of growth hormone in the corn body to one of the most responsive field crop of trace element zinc, promotes photosynthesis; Improve resistance, when corn lacked zinc, growth hormone content reduced; Cell walls can not extend, and growth is suppressed, blade atrophy, distortion; Mosaic disease very easily occurs, influence corn yield.Corn zinc power special slow release fertilizer has added chelating attitude zinc specially, is easy to absorb;
3. the slow-release fertilizer nitrogen nutrient discharges with Maize Absorption and matches
According to research, corn absorbed nitrogen in life have two peaks, and promptly jointing to the typhon mouth phase is built up the phase with earing to seed, and in behind corn seeding 40-90 days this two periods, seedling stage and later stage amount of nitrogen sucking seldom but can not lack.Urease inhibitor and nitrification inhibitor are collaborative to be used, can be to the omnidistance control of nitrogen transformation, and fertilizer efficiency period can reach 90-120 days, in case the corn later stage is taken off fertilizer.Disposable applying during sowing, need not to topdress full vegetative period, simplifies the fertilising flow process, economizes fertile, saving of labor;
4. effect of increasing production is good, and utilization rate of fertilizer is high
Corn zinc power special slow release fertilizer can significantly increase corn yield, improves the particularly utilization ratio of nitrogenous fertilizer of fertilizer.Urease inhibitor and nitrification inhibitor are collaborative to be used, and can reduce the volatilization of ammonia and the leaching loss of nitrate effectively to the omnidistance control of urea-N transformation, improves utilization rate of fertilizer.Compare with executing the common nitrogenous fertilizer of equivalent, use the fertile output of corn zinc power special slow release to improve 20%-25%, utilization rate of nitrogen fertilizer improves 10%-20%.
