Abstract
The invention discloses a dehydrated boron-magnesium-sulfur-iron fertilizer. The dehydrated boron-magnesium-sulfur-iron fertilizer is of white granular appearance, is neutral and is prepared from the ingredients in parts by mass: 100 parts of dehydrated boron-magnesium fertilizer, 30-50 parts of potash fertilizer, 50-60 parts of phosphate fertilizer and 50-70 parts of nitrogen fertilizer. According to the dehydrated boron-magnesium-sulfur-iron fertilizer, a boron-magnesium fertilizer of magnesium sulfate monohydrate is prepared from magnesium sulfate heptahydrate dominated boron-magnesium fertilizers through dehydration, so that the content of effective ingredients is increased, the transportation cost is reduced, and the product is not prone to caking and is convenient in use. The fertilizer contains medium- and micro-elements such as magnesium, sulfur, iron and boron besides three major principal elements, i.e., nitrogen, phosphorus and potassium, so that the effective ingredients are richer, the range of use is wide, the growth of crops is promoted, the resistance to diseases and insect pests of the crops is improved, the fruit ripening is early, and the yield increasing effect is remarkable.
Description
Technical field
The present invention relates to a kind of mineral manure, relate to a kind of dehydration boron magnesium sulphur iron specifically fertile.
Background technology
Boric magnesium fertilizer application is existing obtains certain effect of increasing production for many years, but owing to boric magnesium fertilizer containing the magnesium sulfate heptahydrate of more than 70%, effective constituent is low, transportation cost height, and in long-term placement process, magnesium sulfate heptahydrate very easily loses crystal water, produces caking, it may also be useful to inconvenient. Boric magnesium fertilizer fertilizer efficiency is single, it is used alone the laterite territory band that can only be used for China and seriously lack the area, the middle and lower reach of Yangtze River of magnesium, use range also is subject to using the restriction of area and crop varieties, the half of output that its sales volume is not enough, seriously affects boric acid and improves output because of byproduct for treatment difficulty. Need to be used in combination with other element fertilizer for improving fertilizer efficiency, but the choice and operation amount of fertilizer is unfamiliar with by common user, causes fertilising puzzlement.
The report a few days ago also having some composite fertilizers containing the elements such as nitrogen, phosphorus, iron, zinc, as one open in CN98113666.4 patent makes compound multi-element organic fertilizer with containing iron, magnesium, boron, calcium, molybdenum, phosphorus alkalescence industrial residue and acid waste liquid and animal waste; CN92106742.9 discloses a kind of multi-elements composite fertilizer being made up of become thoroughly decomposed sesame residues and zinc sulfate, boric acid, Repone K, manganous sulfate etc., mutually similar multi-elements composite fertilizer also has some non-patent literatures to report, but this kind of multi-elements composite fertilizer is not all the boron magnesium waste liquid manufacture in adopting boric acid to produce.
See CN01106052.2 about the report of multielement boric magnesium fertilizer to contain: MgSO4��7H2O >=90%, Fe >=0.5%, Na2B4O7��10H2O >=3%, muriate��0.14%; Its main component of CN200710010107.4: boron 1.0��1.2, zinc 0.2��0.5, iron 0.6��1.0, magnesium > 7.0.
Iron zinc microelement is added in above-mentioned patent application in boric magnesium fertilizer, it does not have add the big main fertilizer of N P and K three, therefore can only as the auxiliary fertilizer of main fertilizer, and its effect of increasing production is subject to a definite limitation.
Have not yet to see the report of the multi-elements composite fertilizer containing the big main fertilizer of N P and K three.
Summary of the invention
For current boric magnesium fertilizer Problems existing, the present invention proposes a kind of fertilizer efficiency height, applied range, the simple multi-elements composite fertilizer of production technique.
Solving the problems of the technologies described above the concrete technical scheme taked is: a kind of multi-element composite boron magnesium fertilizer, and its fertilizer forms: in mass parts,
Dehydration boric magnesium fertilizer 100 parts
30��50 parts, potash fertilizer
50��60 parts, phosphate fertilizer
50��70 parts, nitrogenous fertilizer
Multi-elements composite fertilizer of the present invention, outward appearance is white particulate, in neutral, element effective constituent: Mg, S, B, Fe, K, P, N.
Multi-elements composite fertilizer wherein magnesium, sulphur, boron, ferro element is mainly from the boron magnesium waste liquid in boric acid production process, boron magnesium waste liquid concentrates according to a conventional method, crystallization is made based on the boron magnesium crystallization containing magnesium sulfate heptahydrate, by this crystallization at high heat drying and dehydrating make the dehydration boric magnesium fertilizer based on magnesium sulfate monohydrate, wherein principal element content is Mg8%��9%, S12%��14%, B0.4%��0.8%, Fe0.2%��0.3%.
According to different soil application requirement, boron and iron level, lower than requiring, can add boric acid or ferrous sulfate, it is possible to when preparing multi-element composite boron magnesium fertilizer, add boric acid or ferrous sulfate in boron magnesium waste liquid by demand.
The big main fertilizer of nitrogen, phosphorus, potassium three is to select commercially available fertilizer as raw material:
Potash fertilizer is potassium sulfate (K2SO4), Repone K (KCL), saltpetre (KNO3) etc. sylvite wherein one or more mixing.
Phosphate fertilizer is with ammonium phosphate ((NH4)3PO4), primary ammonium phosphate (NH4H2PO4), Secondary ammonium phosphate ((NH4)2PO4), secondary calcium phosphate (CaHPO4), potassium primary phosphate (KH2PO4), double superhosphate (Ca (H2PO4)2��H2Phosphoric acid salt one or more mixing wherein such as O).
Nitrogenous fertilizer is with ammonium sulfate ((NH4)2SO4), bicarbonate of ammonia (NH4HCO3), ammonium chloride (NH4Cl), ammonium nitrate (NH4NO3), lime nitrogen (CaCN2), urea (CO (NH2)2) etc. chemical nitrogen fertilizer be main, can use wherein one or more mixing.
The nitrogen of multi-element composite boron magnesium fertilizer, phosphorus, the kind of potash fertilizer and the selection of addition, with the material that material price, edaphic condition, crop species selecting factors are suitable.
The useful effect of the present invention: the present invention, due to the boric magnesium fertilizer by magnesium sulfate heptahydrate being master, makes the boric magnesium fertilizer of magnesium sulfate monohydrate, effective constituent is improved through dehydration, reduces transportation cost, and product prevented from caking, it may also be useful to convenient. Except containing also having amount and trace element in magnesium, sulphur, iron, boron etc. except nitrogen, phosphorus, the big principal element of potassium three, effective constituent is abundanter, it may also be useful to scope is wide, promotes plant growth, it is to increase crop disease-resistant insect pest ability in fertilizer, fruit maturation early, obvious effect of increasing production.
