Abstract

The invention relates to the fertilizer prepration technology field, in particular to a chelated root fertilizer and a preparation method thereof. The invention provides the chelated root fertilizer for solving the problem of fertilizer pollution of soil caused by the prior fertilizer, and the chelated root fertilizer is obtained by full stirring nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, middle element fertilizer, trace element fertilizer, organic acid, organic amine, physiological active substances and water in a reaction tank for carrying out the reaction for a period of time. The chelated root fertilizer contains necessary nutrient elements needed by plant growth, the utilization rate of the nutrients can reach 30 percent to 65 percent by being matched with conventional fertilizers for use, therefore, the chelated root fertilizer belongs to the fertilizer with high utilization rate; the application amount can be less than the ordinary compound fertilizer by 20 percent under the premise of achieving the same yield, thereby having obvious economic benefits.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a chelated root fertilizer and a preparation method thereof. Background technique [0002] Among the major agricultural countries in the world, the average annual chemical fertilizer application per unit area in my country is the highest, which is 9, 4.3 and 2.42 times that of Russia, Canada and the United States respectively. The average productivity per kilogram of fertilizer is the lowest, 4.4, 3.4 and 3.7 times lower than Russia, Canada and the United States respectively. Taking nitrogen fertilizer as an example, the utilization rate of nitrogen fertilizer in my country is only 30-40%, and it is 50-60% in the world's agricultural developed countries, which is 20-30 percentage points higher than that in my country. Unreasonable fertilization has caused a serious imbalance of soil nutrients, soil compaction and acidification, and the productivity and disaster re...
