The additive can be solely applied to soil to meet the requirement for N and S fertilizers, trace element and soil improvement; the additive can also be added to various complex and compound fertilizers; the fertilizer utilization ratio can be improved by 8-25% and the yield of crops can be improved by 5-20%.
Description
Technical field
The present invention is a kind of environmental friendly sustained-release synergistic multifunctional fertilizer additive.Belong to fertilizer additive.Be particularly related to a kind of environmental friendly sustained-release synergistic multifunctional fertilizer additive that contains thiosulphate, sustained release dosage and soil improvement material.
Background technology
The production of chemical fertilizer and use were once fast in fertilizer efficiency, improve crop yield and each side easy to use has been brought into play active effect.But, the result of life-time service, the negative impact that its inherent defective is brought is more and more outstanding.For example: the utilization rate of fertilizer that decomposition rate causes soon is low; Degradation production discharges the pollution for atmosphere, water body caused; Cause soil compaction, the ecological environment of soil of plant growth is destroyed or the like.In the prior art, people adopt technical schemes such as adding nitrogen fertilizer slow releasing agent, are slowing down nitrogenous fertilizer release, improve the certain effect of utilization rate of nitrogen fertilizer aspect performance, still are confined to nitrogen fertilizer slow-releasing, and are very little to the sustained-release synergistic effect of other fertilizer components; Powerless to environment protection and soil improvement.And cost an arm and a leg, increased the manufacturing and the agriculture production cost of fertilizer.
A kind of protection environment, improve the soil, increase effective fertilizer composition, slow release effect significantly, improve utilization rate of fertilizer, and be applicable to that the environmental friendly sustained-release synergistic multifunctional fertilizer additive of various chemical fertilizer is that people expect.
Summary of the invention
The objective of the invention is to avoid above-mentioned weak point of the prior art and a kind of protection environment is provided, improves the soil; increase effective fertilizer composition; slow release effect is remarkable, the raising utilization rate of fertilizer, and is applicable to the environmental friendly sustained-release synergistic multifunctional fertilizer additive of various chemical fertilizer.
The waste that the present invention also aims to adopt industrial discharge is turned waste into wealth as components of additives of the present invention, administers and pollutes, the protection environment.
Purpose of the present invention can reach by following measure:
Environmental friendly sustained-release synergistic multifunctional fertilizer additive of the present invention is characterized in that comprising following feed composition (weight part):
Ammonium thiosulfate 3-50
