Abstract
The invention disclose a slow-release agent of a functional nitrogenous fertilizer, comprising the following components by weight: 2-5 parts of synergistic sodium, 130-150 parts of dicyandiamide, 140-160 parts of magnesium sulfate, 140-160 parts of nano-carbonate calcium, 280-320 parts of zeolite powder and 250-270 parts of amargosite. The invention can not only maintain long effect and slow effect of the nitrogenous fertilizer, but also can ensure quick effect of the nitrogenous fertilizer, so that crops can be supplied with enough nitrogenous balance during the whole growth period. The invention can be randomly mixed and fertilized with the nitrogenous fertilizer; the dosage is reduced by 20%-30% compared with the normal dosage of conventional fertilizing so as to be convenient for farmers, save labor and cost and increase yield.
Description
Technical field
The present invention relates to the agro-ecology field, specifically is a kind of slow-release agent of functional nitrogenous fertilizer.
Background technology
Nitrogen fertilizers is more, like urea, carbon ammonium, sulphur ammonium, ammonium chloride, ammonium nitrate or the like, huge contribution has all been made in the agriculture prodn of new China.But, because long-term excessive applied nitrogen has also caused huge negative to environment.For example, the nitrogen peroxide that urea generates in amide hydrolysis, nitrification and denitrification process is along with ammonia volatilization loss is huge, and escaping into atmosphere generation Greenhouse effect has by substantial connection global warming; With rainwater loss rivers or infiltration deep subsoil, cause rivers and groundwater azotate severe overweight, threatening human health.Minimizing amount of application of nitrogen fertilizer, raising utilization rate of nitrogen fertilizer have arrived instant stage! Therefore, the revolution of " raising utilization rate of nitrogen fertilizer " has begun, and people set about researching and developing various slow, release and release control fertilizers in the hope of reaching the purpose that improves utilization rate of nitrogen fertilizer.
Slow, controlled-release technology commonly used are roughly following approach:
1, bio-chemical pathway---urase suppresses and inhibiting nitrification;
2, physical method---encapsulate method, pack;
3, chemosynthesis release method---insoluble organic cpds, water-soluble difficult degradation compound, low-solubility inorganic salt.
More than any method the possibility that improves utilization rate of nitrogen fertilizer is all arranged; But, the field crop demonstration embodies many not ideal parts in applying; Like sulfur coating, polymer capsule, fused(calcium magnesium)phosphate coated slow releasing fertilizer; It is vigorous in use in the land for growing field crops, the later stage generally to occur, and lack nutrition early stage, still need handle accordingly.Therefore, in the crop large-area applications, remain further to be innovated.
Summary of the invention
The invention provides a kind of slow-release agent of functional nitrogenous fertilizer, and can use behind the nitrogenous fertilizer mixing, very convenient with mixing with executing, and usage quantity is compared with conventional fertilizer application and can be reduced 20～30%.
Technical scheme of the present invention is:
A kind of slow-release agent of functional nitrogenous fertilizer is characterized in that: each component is by weight than being:
Synergy sodium 2-5
Dyhard RU 100 130-150

Zeolite powder 290-310
Wilkinite 255-260
Described slow-release agent of functional nitrogenous fertilizer is characterized in that: each component is by weight than being:
Synergy sodium 3
Dyhard RU 100 140
Sal epsom 150
Nanometer grade calcium carbonate 150
Zeolite powder 300
Wilkinite 257
The present invention can make nitrogenous fertilizer long-acting and slow; Can make nitrogenous fertilizer have quick-acting functions again, guarantee that farm crop all have enough nitrogen nutrition stable market supply in whole growing, and with nitrogenous fertilizer with mixing with executing; Make things convenient for the peasant to use, reach and save the purpose that labour, abridged edition increase income.
With existing compared with techniques, The present invention be directed to the characteristic of present peasant habit fertilising, under the prerequisite that does not change its characteristic, reach the effect of " reduce amount of application of nitrogen fertilizer, improve utilization rate of nitrogen fertilizer ".The present invention does not have any hormone, nontoxic, harmless, pollution-free; Use the back instant effect, fertilizer efficiency is steady, the lasting period is long, strengthen that farm crop are cold-resistant, drought resisting, waterlogging-resistant, resist saline and alkaline function.Increase output, improve quality, peasant's abridged edition is increased income.
Embodiment
With each feed composition: after 257 parts in 3 parts in synergy sodium, 140 parts of Dyhard RU 100s, 150 parts in sal epsom, 150 parts of nanometer grade calcium carbonates, 300 parts of zeolite powders, wilkinite carry out automatic gauge through electronics automatic gauge scale; Each component after the proportioning is put into the powder mixing machine to mix; Then the component that stirs is put into autometering packaging machine and pack, get finished product.
Claims (4)
1. slow-release agent of functional nitrogenous fertilizer, it is characterized in that: each component is by weight than being:
