Description
Technical field
The invention belongs to Crop fertilizer field, more particularly to a kind of Water soluble fertilizer and preparation method thereof.
Background technology
Water soluble fertilizer is a kind of water-soluble polyelement composite fertilizer, is a kind of new-type fertilizer of rising in recent years, and it can be fast
Speed is dissolved in the water, it is easier to is absorbed by crops, and absorption rate is of a relatively high, realizes water-fertilizer integral, reaches
Water-saving saves the effect of fertile saving of labor.China is a large agricultural country, populous, water resource famine, and occupancy volume per person is suitable
In the 1/4 of world occupancy volume per person, the share for agricultural production is also constantly declining, and has formed one and very severe has asked
Topic, agriculturally, greatly developing for water-saving fertilizer can not urgently be treated.
China greatly develops modern agriculture at present, increasing to the demand of new-type fertilizer, and requires also more and more higher.
With the rise of water-saving agriculture, the especially full water-soluble fertilizer of water-soluble fertilizer obtains development opportunity.Compare the life of concentration in fruits and vegetables
Is produced from base, the popularizing area of water-soluble fertilizer is big, peasant household's degree of recognition is high.Due to conventional composite fertilizer raw material do not possess mostly it is complete water-soluble
The fertilizer that feature, such as ground phosphate rock, calcium superphosphate, calcium magnesium phosphate are commonly used in agricultural, because dissolubility is limited, is not used as water
Molten fertile raw material；Even if being used as Water soluble fertilizer raw material from solubility preferably ammonium dihydrogen phosphate, potassium nitrate, potassium sulfate etc., due to
Limited purity, it is also difficult to meet completely water-soluble requirement.Existing conventional fertilizers raw material, which is changed into Water soluble fertilizer, needs constantly purification, not only
Energy consumption is caused to raise, cost increase, and also nutrient becomes single.
Furthermore Water soluble fertilizer is typically the complex of various nutrient elements, due to the performance of different fertilizer raw material in compound
Have differences, by the change of the Water soluble fertilizer that plurality of raw materials forms self performance and environment in storage, use, cause fertilizer water-soluble
Property be deteriorated, or even it is water-soluble when react to each other generation precipitation, the defects of this use to Water soluble fertilizer is serious, it is impossible to adapt to water completely
The requirement of fertile Integrated fertilizer application, can not only result in blockage pipeline, and fertilizer efficiency can heavy losses.
The content of the invention
In order to solve the above-mentioned technical problem the present invention provides one kind and is not easy to precipitate, fertilizer efficiency is lost in, and can be effectively promoted plant
