Abstract

The invention discloses a crop trace element organic complex fertilizer and a preparation method thereof. The preparation method includes: adding urea, citric acid, ZnSO4, borax, ammonium molybdate, CuSO4, FeSO4, MnSO4 and vitamin into a reaction kettle in order for stirring, dissolving and mixing so as to conduct a complexing reaction, then adding element Ti, leaving the Ti and the remaining vitamin, urea and citric acid that do not participate in the complexing reaction to undergo a complexing reaction again, adding KOH, ammonia water and sodium dodecyl benzene sulfonate to conduct adjustment and stir them uniformly, thus obtaining a finished product. The preparation method provided in the invention has fewer technical residue and small raw material loss. The prepared trace element organic complex fertilizer is a slightly acidic buffer solution, and is prepared from trace elements and organic complexes, thus being more suitable for crop absorption. Meanwhile, the prepared trace element organic complex fertilizer also has the advantages of small application dose, comprehensive nutrition, no heavy metal pollution residual, crop quality improvement, and capability to control replant diseases and a plurality of crop diseases.

Description

technical field [0001] The technical scheme of the invention relates to a chemical fertilizer containing various trace elements, in particular to a preparation method of an organic complex fertilizer containing various trace elements required for crop growth. Background technique [0002] my country's agriculture has entered a new stage of development, but the fertilizers used for crops, vegetables, fruit trees and other plants are mainly traditional nitrogen, phosphorus and potassium solid fertilizers. Long-term use is not conducive to field operations, and it is easy to cause crop burns, and the utilization rate of chemical fertilizers is not high, resulting in serious waste. , resulting in a decline in comprehensive soil indicators, an increase in alkalinity, soil compaction, and weakened soil fertility, resulting in a rapid decline in crop quality and yield, and poor taste. This undoubtedly increases production costs and reduces agricultural production efficiency. [0003...
