Abstract

The invention provides a high-activity multi-element compound fertilizer special for corn and a preparing method thereof. The high-activity multi-element compound fertilizer is prepared from, by weight, 6-20 parts of humic acid, 40-60 parts of urine, 10-25 parts of monoammonium phosphate, 5-25 parts of potassium chloride, 0.5-3.5 parts of zinc sulfate, 0.2-2 parts of borax, 2-10 parts of sepiolite powder, 2-6 parts of hydrochloric acid solution and 4-13 parts of water. Hydrochloric acid is used for completing active treatment on humic acid, indissolvable calcium humate and magnesium humate are generated into dissolvable calcium and magnesium salt which can be absorbed and used by crops better. The nutrient matching of the compound fertilizer meets the characteristics of fertilizer needed by corn, and the compound fertilizer is rich in medium trace element and organic matter which are more suitable for corn growth and has the effects of promoting fertilizer synergism, improvement, activating and repairing soil, increasing crop yield and improving crop quality.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special compound fertilizer for high-activity multivariate corn and a preparation method thereof. Background technique [0002] "A single flower in a crop depends entirely on fertilizer", the widespread use of chemical fertilizers in my country's agricultural production for many years has made great contributions to agricultural development, farmers' income increase and rural prosperity. However, the extensive use of chemical fertilizers for a long time has also caused excessive soil salinity, excessive concentration of harmful ions, poor structure, easy compaction, uneven fertility in the soil, decreased fertility, and restricted crop growth and development. According to data, soil pollution in my country is becoming more and more serious, and saline-alkaline soil is growing rapidly. Improving the soil and protecting the ecological environment have attracted g...
