Problems solved by technology

This not only wastes energy, but also causes the accumulation of harmful substances such as nitrate in soil and water and pollutes the environment
In addition, the existing nitrogen fertilizers have relatively simple nutrition. Although they can promote plant growth, they cannot meet the requirements for iron deficiency and stress resistance of crops, and long-term application will easily lead to soil compaction and deterioration of the soil environment.

The synergism and lost control fertilizer provided by the invention has advantages of high fertilizer utilization rate, prolonged fertilizer efficiency period, high yield of crop, quality improvement of agricultural product, soil improvement and fertility betterment, easy identification product color, excellent appearance quality, convenient mechanical fertilization, low production cost, simple technology, safety usage and high benefit.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a synergistic loss-controlling fertilizer and a preparation method thereof. Background technique [0002] At present, the fertilizer effect on most crops in my country is still the highest with nitrogen fertilizer. Nitrogen is a nutrient element with special significance in plant life. Nitrogen fertilizer is the most widely used fertilizer in agriculture. Nitrogen fertilizer products mainly include urea, ammonium chloride, ammonium sulfate, ammonium bicarbonate, ammonium nitrate and liquid ammonia. Once ordinary nitrogen fertilizer is applied to the soil, it will undergo a series of biochemical changes under the action of various soil microorganisms and the enzymes they secrete, constantly changing its form, making it more mobile in the soil, and even leaching with water and following Gaseous volatile loss. According to estimates, the seasonal utilization rate of nitrogen f...
