Over nearly 30 years,, and ignored raising to improvement of soil fertility and soil fertility because people only pay attention to improving grain yield, by a large amount of input chemical fertilizer, this has also increased the weight of soil compaction, and soil aggregate is destroyed, the soil severe contamination, to such an extent as to yield per unit is extremely not low to fertilize, and the grain quality reduction, because the chemical fertilizer nutrient of using is single, proportioning is unreasonable, science has not promptly caused the manure resources waste, defines the raising of unit surface grain yield again.Especially corn planting, because the increase year by year of rate of fertilizer application, and method is improper, has increased peasant's labour intensity greatly, the situation that Higher output is not accompanied by a higher income occurred.Therefore, the peasant urgently looks forward to having a kind of anti-saline and alkaline long-acting corn fertilizer.
Summary of the invention
The object of the present invention is to provide a kind of nutrient equilibrium, be applicable to the long-acting corn fertilizer that use in the saltings, the present invention can improve alkaline land soil, increases substantially corn yield.
For achieving the above object, organic-inorganic of the present invention resists saline and alkaline long-acting corn fertilizer, the effective ingredient that mainly contains following weight proportion: nitrogen 10-28%, phosphorus 5-20%, potassium 5-18%, sulphur 10-25%, amino acid 5-10%, humic acids 1-10%, middle micro-1-5%, sustained release drug 1-5%, surplus is a binding agent.
Described nitrogenous fertilizer can be selected from least a in urea, ammonium chloride, the ammonium sulfate.Described phosphate fertilizer can be selected from least a in calcium superphosphate, monoammonium phosphate, diammonium phosphate, the double superhosphate.Optional at least a in vitriolate of tartar, Repone K of described potash fertilizer.Amino acid is selected from the tankage of amino acids fertilizer or corn processed.
Trace element comprises in described: zinc 0-1.5%, magnesium 0-3%, iron 0-1%, silicon 0-1%, calcium 0-0.5%, molybdenum 0-0.5%.
Described binding agent is a cohesive soil.
Preparation method of the present invention is: with adding binding agent in the above-mentioned raw materials as carrier, make by granulation behind the mechanical mixing.
Organic-inorganic of the present invention resists saline and alkaline long-acting corn fertilizer, is a kind ofly to collect chemical fertilizer and organic fertilizer is the compound fertilizer of one.Advantage of the present invention is:
1, nutrient is complete, not only contains the essential nitrogen of plant growth, phosphorus, potassium three big nutritive elements, and it is micro-in the kind more than 20 also to contain zinc, iron, sulphur, boron, manganese, silicon, molybdenum etc. simultaneously.
2, organic and inorganic combining both contained inorganic chemical fertilizer, contained organic fertilizer again.
3, fertilizer efficiency period is long, but subsoil-application fertilizer, and the middle and later periods needn't topdress, and can satisfy the needs to various nutrients in corn all one's life, and the later stage is not taken off fertilizer.
4, has anti-saline and alkaline effect.Owing to added physiological acidic fertilizer in the fertilizer, particularly add organic corruption and planted the matter acidic fertilizier, played the effect of regulating the alkaline land soil aqueous ph value, carbonate and the nitrate in the soil of having degraded, the accumulation of salt in the surface soil accumulation of salt in the surface soil slightly and even not after autumn, and the plot of local conventional fertilizer application just has tangible accumulation of salt in the surface soil phenomenon to produce.Long-term fertilization can increase soil organic matter content simultaneously, impels the formation of soil aggregate, has improved soil, improves the soil permeability energy, for Maize Production has been created good edatope.
5, the anti-saline and alkaline long-acting corn fertilizer of organic-inorganic of the present invention is used in increasing both production and income, the comparable 200 jin of corns of volume increase of using conventional fertilizer of per mu yield, and amount of increase in production reaches 13.1%.
