Abstract
The invention discloses a sustained release special fertilizer suitable for inland saline-alkali soil forage grass sorghum. The sustained release special fertilizer is prepared by mixing components of which the granularity is 2.00-4.75mm in parts by weight: 10-30 parts of sulfur coated urea, 10-30 parts of resin coated urea, 10-30 parts of large granular urea, 10-30 parts of granulated phosphate fertilizer, 10-30 parts of granulated potassium fertilizer, 1-10 parts of granulated zinc fertilizer and 1-10 parts of specific fertilizer filler, wherein the specific fertilizer filler is prepared by mixing and granulating desulfurization gypsum, humic acid and attapulgite. Due to use of urea in different sustained release periods, available nutrients and sustained release nutrients are combined, topdressing is avoided in middle term after basal application; the formula contains inland saline-alkali soil improvement factors; and therefore the sustained release special fertilizer is suitable for the inland saline-alkali soil, is high in targeted performance, high in nutrient content and convenient to use.
Description
Technical field
The present invention relates to a kind of dedicated fertilizer, particularly relate to a kind of saltings Special Fertilizers for Various Crops material.
Background technology
China 9,913 ten thousand hectares, existing saltings, wherein inland-type saltings area is maximum, accounts for 69% of whole saltings.Saltings, inland has the features such as surface soil alkalinity is strong, Sodium by substitution ion content is high, soil physical property is poor.
Forage Sorghum ecological suitability is wide, and drought resisting, waterlogging-resistant, barren-resistant, Salt And Alkali Tolerance, be a kind of important fodder crop, nutritive value and biological yield are all very high.Have very large difference with common Chinese sorghum of brewageing, Forage Sorghum is to gather in the crops over-ground part cauline leaf, fast growth, and regenerative power is strong.Forage Sorghum will carry out 1 ~ 2 time cradling within breeding time, and nutritional needs is vigorous, brewages Chinese sorghum and wants high a lot, present special nutrient requirement characteristics to the demand of nitrogen, phosphorus, potassium especially nitrogenous fertilizer is more common.In addition, in Forage Sorghum whole breeding time to the demand of the nutrient demand of nitrogen, phosphorus, potassium especially nitrogenous fertilizer in " S " type curve, early stage, demand was low, and Post flowering sharply increases, and later stage demand is steady.
Forage Sorghum Salt And Alkali Tolerance ability is strong, and having extensive plantation in RS in Alkali Region, inland, is one of pioneer crop of inland alkaline land improving.But at present about the Slow release special fertilizer of saltings, inland Forage Sorghum have not been reported, the problem that in the plantation of saltings, inland Forage Sorghum, existence fertilising blindly, nutrient is unbalanced, Later growth takes off fertile serious, saline and alkaline adaptive faculty difference, on market, related fertilizer product is deficient.Compound manure used in current sorghum production is mainly readily avaiable fertilizer, and nitrogenous fertilizer is in large supply for early stage, but Chinese sorghum demand is few, and later stage nitrogenous fertilizer demand is large, but has discharged totally, causes the later stage de-fertile serious, directly affects crop yield.
Therefore, according to the demand of current alkaline land improving and the trend of Slow release special fertilizer development, developing the Forage Sorghum Slow release special fertilizer being used for saltings, inland, is the technical measures be badly in need of.
Summary of the invention
The object of the invention is the deficiency solving prior art existence, provide a kind of available nutrient and slow nutrient to combine, be applicable to the Slow release special fertilizer of saltings, inland Forage Sorghum.
The Slow release special fertilizer being applicable to saltings, inland Forage Sorghum of the present invention is made up of the inorganics of nitrogenous, phosphorus, potassium and trace element and filler blending, particularly, it is be made up of the component blending of following portions by weight: sulfur-coated urea 10 ~ 30 parts, resin-bonded grinding wheel 10 ~ 30 parts, granular urea 10 ~ 30 parts, granulated phosphate fertilizer 10 ~ 30 parts, granular potash fertilizer 10 ~ 30 parts, particle zinc fertilizer 1 ~ 10 part, special fertilizer filler 1 ~ 10 part.
Wherein, described special fertilizer filler is made up according to 5:4:1 mixing granulation of desulfurated plaster, humic acids and convex Attapulgite.
In the present invention, the preferred sulfur-bearing of described sulfur-coated urea 10%, nitrogenous 37%, granularity 2.00 ~ 4.75mm, release number of days is the sulfur-coated urea slow-release fertilizer of 30 ~ 60 days.
In the present invention, described resin-bonded grinding wheel preferably nitrogenous 44%, granularity 2.00 ~ 4.75mm, release number of days is the resin-bonded grinding wheel slow-release fertilizer of 60 ~ 90 days.
In the present invention, described granular urea nitrogenous 46%, granularity 2.00 ~ 4.75mm.
In the present invention, described granulated phosphate fertilizer is the one in monoammonium phosphate and diammonium phosphate, or the mixture of two kinds, and granularity is 2.00 ~ 4.75mm.
In the present invention, described granular potash fertilizer is the one in potassium sulfate and Repone K, or the mixture of two kinds, and granularity is 2.00 ~ 4.75mm.
In the present invention, described particle zinc fertilizer is zinc sulfate, containing zinc 34%, and granularity 2.00 ~ 4.75mm.
In the present invention, the preferred flue gas desulphurization gypsum of the desulfurated plaster in described special fertilizer filler.
The preparation method being applicable to the Slow release special fertilizer of saltings, inland Forage Sorghum of the present invention is that to obtain particle diameter relative consistent by the screening of described sulfur-coated urea, resin-bonded grinding wheel, granular urea, granulated phosphate fertilizer, granular potash fertilizer, particle zinc fertilizer and special fertilizer filler, granularity is the particle of 2.00 ~ 4.75mm, joining according to described parts by weight puddles in machinery, mixing and stirring, obtains described Slow release special fertilizer.
Slow release special fertilizer of the present invention is applied mainly as saltings, inland Forage Sorghum plantation base manure, and concrete using method is applied once, every mu of amount of application 40 ~ 60kg.
The Slow release special fertilizer being applicable to saltings, inland Forage Sorghum provided by the invention has taken into full account saltings Forage Sorghum different requirements to nitrogenous fertilizer within whole breeding time, coordinated by the urea of different slow-release period, available nutrient is combined with slow nutrient, coordinate Forage Sorghum growth in earlier stage, mid-term and different bearing stage in later stage are to the different demands of nitrogenous fertilizer, the supply of nutrient in the fertilizer requirement of Forage Sorghum and soil is matched, guarantee that Forage Sorghum obtains suitable nutrient supply amount at Different growth phases, improve the utilising efficiency of nutrient, and base is executed and is no longer needed rear mid-term to topdress, save labor.Contain the inland alkaline land improving factor in Slow release special fertilizer of the present invention, be applicable to saltings, inland, with strong points, nutrient content is high, uses conveniently.
