Description
Technical field
The present invention relates to a kind of Fu Gai composite fertilizers and preparation method thereof.
Background technology
Crops and ornamental plant need to absorb more nutriment in a growth cycle.Fertilizer can
Nutrient needed for crop is provided, changes the component of soil, the fertility of soil is improved, increases having for soil
Machine material.Rational fertilising growing for crop, promotes crop metabolism, improves crop unit
Area output plays conclusive effect.
Nitrogen, three kinds of elements of calcium and potassium are the essential elements of crop growth.Nitrogen has acyl state nitrogen, nitre
State nitrogen, three kinds of states of ammonium nitrogen are present, and urea can not be directly absorbed by plants, it is necessary to by urinating enzyme point in itself
Solution could absorb into ammonium nitrogen, crop, thus prolong the acquisition time for having risen nitrogen, can play long-acting effect；
And applying ammonium nitrogen and nitrate nitrogen can allow crop directly to absorb, the effect having immediate effect, but the concentration of ammonium nitrogen
Height, under conditions of being particularly warm, ammonium nitrogen resolves into ammonia volatilization, causes ammonia to damage and burn seedlings.It is existing
In fertilizer, the only nitrogen containing two kinds of forms, it is impossible to realize that acyl state nitrogen, nitrate nitrogen, ammonium nitrogen (three nitrogen) coexist,
On the other hand, calcium can form calcium sulfate with other elements in composite fertilizer, and the dissolubility of calcium sulfate is not high, causes
The loss of calcium source.
