Description
Technical field
The present invention relates to microbial manure technical fields, and in particular to a kind of water soluble fertilizer of a great number of elements and its preparation
Method.
Background technology
Water soluble fertilizer be one kind can quickly be dissolved in water or dilute for fertigation, page fertilising, soilless culture,
The liquid or solid fertilizer of the approach such as seed soaking, root dipping.Compared to Common compound fertilizer material, water soluble fertilizer is quick, fertile with absorbing
It imitates using height, can be applied to the advantages that water-fertilizer integral.In recent years, China's water soluble fertilizer is quickly grown, and is gradually formed a large amount of
The multiple types fertilizer such as element Water soluble fertilizer, trace element water-soluble fertilizer, Water soluble fertilizer containing amino acid, Water soluble fertilizer containing humic acid.
A great number of elements Water soluble fertilizer refers at least containing 2 kinds of a great number of elements in nitrogen, phosphorus, potassium, and contains in calcium, magnesium and measured in a kind
The solid or liquid fertilizer of element or more.A great number of elements Water soluble fertilizer has the characteristics that full water-soluble and highly compatible, can realize
Fertigation is combined, and has the characteristics that water-saving, section fertilizer, saving of labor, efficient, thus is widely used in agricultural production, particularly
In the modern agriculture furnished equipments such as sprinkling irrigation, trickle irrigation, soilless culture.But existing Macroelement water-soluble fertilizer uses phosphoric acid more
Root（Potassium phosphate,monobasic, potassium dihydrogen phosphate）As phosphorus source, and phosphate anion easily generates precipitation with the calcium ions and magnesium ions of addition, both
The validity of calcium, magnesium, zinc, iron, copper, manganese, molybdenum and P elements is reduced, and easily makes the water-insoluble of product exceeded, it is therefore desirable to
Complexing agents and the chelating agents such as EDTA, citric acid, humic acid are added in, increases the cost of fertilizer.
