Abstract
The present invention is a kind of zeolite long-acting compound fertilizer that contains, because reaching, the decomposition volatilization of common chemical fertilizer in soil lose with current, utilization ratio is only about 50%, and fertilizer efficiency is also shorter, the present invention adopts resource extensive, abundant natural zeolite is as additive, join in the chemical fertilizer, utilize its adsorption, make the utilization ratio of chemical fertilizer improve 22%～33%, make fertilizer efficiency prolong 2～3 times, and the cost of chemical fertilizer also descends to some extent, can also improve simultaneously the cationic exchange energy of soil, reduce the pollution of farm crop, and some crop growth trace elements necessary can be provided in soil.
Description
The present invention relates to a kind of chemical fertilizer, particularly a kind of long-acting compoundization material of zeolite that contains.
Because the decomposition of chemical fertilizer in soil, volatilization reaches and loses with current, the utilization ratio that causes common chemical fertilizer is only about 50%, and fertilizer efficiency is shorter, so people adopt the whole bag of tricks to try hard to prolong its fertilizer efficiency, improves the utilization ratio of chemical fertilizer, one of its method is for producing various controlled availability fertilizers, wherein, promptly outside chemical fertilizer granule, clad the slow soluble substance of last layer, to reduce the decomposition and the volatilization of chemical fertilizer based on long-acting Wrapped fertilizer.But facts have proved for many years, the effect of this Wrapped fertilizer is unsatisfactory, and cost is also higher, technology is complicated, Gazette of Patent for Invention discloses a kind of the contain long-acting urea fertilizer of Resorcinol and the patent application of production technique thereof with CN85109580 A number recently, and this fertilizer is to add quantitative Resorcinol as the urea decomposition inhibitor in urea fertilizer.But the cost of this inhibitor is higher, and the urea fertilizer cost is increased, and it only is suitable for a kind of chemical fertilizer of urea, and application surface is also narrower.
The object of the present invention is to provide a kind of new controlled release chemical fertilizer, it can improve the utilization ratio of chemical fertilizer, prolong fertilizer efficiency, and application surface is wider, and cost is lower.
The objective of the invention is to realize by the following technical solutions: the zeolite powder of suitable proportion is added in the chemical fertilizer, behind thorough mixing, can use, if can place back use more than 24 hours, effect can be better.
Zeolite powder purity used in the present invention is more than 40%, and grinding particle size is 80～100 orders, and it can be applicable to various chemical fertilizer such as nitrogen, phosphorus, potassium, and according to the adsorption rate difference of zeolite for various chemical fertilizer, its proportioning is (by weight percentage):
Nitrogenous fertilizer: zeolite content is 10～50%;
Phosphate fertilizer: zeolite content is 30～40%;
Potash fertilizer: zeolite content is 25～35%.
The present invention adopts extensive, the abundant natural zeolite of resource, after crushed as additive, joins in the chemical fertilizer, utilizes the adsorption of zeolite, controls the release of chemical fertilizer effectively, thereby can make quick-acting fertilizer become long-acting fertilizer, can improve the utilization ratio of chemical fertilizer.The experiment proved that, contain of the utilization ratio raising 22%～33% of zeolite composite chemical fertilizer than common chemical fertilizer, fertilizer efficiency can prolong 2～3 times, crop yield on average increases by 10～20%, reach as high as 27.3%, and can reduce the consumption of chemical fertilizer relatively, the cost of chemical fertilizer per ton is descended 40～50 yuan, the zeolite composite chemical fertilizer that contains of the present invention also has and does not lump, few volatilization, reduce advantages such as pungent odour, particularly for not too welcome ammonium hydrogencarbonate, effect is especially remarkable, in addition because zeolite for the residual adsorption effect of heavy metal ion, contains the effect that the zeolite composite chemical fertilizer can also play the minimizing crop pollution.As use year after year, the soil is not hardened, improve its impregnability, improve the cationic exchange energy of soil, and some crop growth trace elements necessary can be provided in soil.
The invention will be further described below in conjunction with embodiment.
Because the content difference of various chemical fertilizer, the quantity that therefore adds zeolite powder is also different, below provides the proportioning of the contained zeolite of various chemical fertilizer:
Nitrogenous fertilizer: sulphur ammonia: nitrogen content is added zeolite powder 24%～33% 20%
Carbon ammonia: nitrogen content is added zeolite powder 10%～20% 17%.
Urea: nitrogen content is added zeolite powder 49%～50% 40%.
Phosphate fertilizer: calcium superphosphate: contain Vanadium Pentoxide in FLAKES 11.6%, add zeolite powder 30%.Phosphoric acid ammonia: contain Vanadium Pentoxide in FLAKES 30.6%, add zeolite powder 40%.
Potash fertilizer: vitriolate of tartar: contain potassium oxide 43%.
Add zeolite 25～30%.
Repone K: contain potassium oxide 58.6%, add zeolite powder 35%.
