Description
Technical field
The invention belongs to technical field of chemical fertilizer production, and in particular to a kind of trace element chelated fertilizer and preparation method thereof.
Background technology
Plant is in growth course, in addition to needing substantial amounts of nitrogen, phosphorus, potassium, in addition it is also necessary to a certain amount of trace element, if
Lack these trace elements, plant is then unable to normal growth, the method for solving the problem is exactly micro- fertilizer in applying.Normally applying
In the case of nitrogen, phosphorus, potassium, increase containing fertilizer micro- in one or more, element needed for crops, preventing and treating can be balanced
Physiological disturbance caused by nutritional deficiency.The middle many metal ions with divalence of trace element that China uses are present, once apply
In soil and entrance plant, because there is the carbonate of negative divalence in soil and plant, generation is easily reacted water insoluble
Carbonate, will largely lose activity, what can be absorbed by plants is seldom, utilization rate by a definite limitation, even if so balance
Fertilising, is also not equal to by crops Balance Absorption why, here it is the balance fertilizing in soil, but crops are sometimes still
The reason for there is nutritional deficiency symptom.In order to solve this contradiction, in the past by the use of EDTA (ethylenediamine tetra-acetic acid) and humic acid etc. as
Chelating agent, chelate is generated by trace element, is effectively improved the stability of trace element, it is to avoid its generation is water insoluble
Carbonate and phosphate, improve the utilization rate of fertilizer, and fertilization effect is improved.
In above-mentioned chelating agent, though EDTA sequestering powers are strong, its cost is high, be easily degraded in soil glyoxalic acid and
Formaldehyde etc., endangers plant growth；Humic acid molecular weight is larger, complicated, influences the absorption efficiency of its composite fertilizer formed.
Therefore, it is more using harmful effect, the simple amino acid of molecular structure will not be produced to plant as chelating agent, such as at present
Chinese patent literature CN102153418A discloses a kind of efficient amino acid chelated leaf fertilizer containing trace elements, and it is to use ammonia
Base acid goes chelating various middle micro-.
Although there is above-mentioned advantage as chelating agent using amino acid, there is also the limitation of its own, that is,
Its sequestering power is weak, easily occurs hydrolysis in plant or easily reacts and inactivate with other anion, therefore causes its shape
Into trace element chelated fertilizer in metal-chelating rate it is low, stability is poor, and fertilizer efficiency is substantially reduced.
The content of the invention
Therefore, the existing defect that trace element chelated fertilizer existence and stability is poor, chelation percent is low to be solved by this invention, enters
And provide that a kind of stability is good, chelation percent is high, absorptivity and fertilizer efficiency is high, nutrition trace element chelated fertilizer and its preparation side in a balanced way
Method.
