一种缓释中微量元素的卡波姆凝胶肥料及其制备方法
By using a carbomer gel fertilizer preparation method and a dual chelation process of compound sugar alcohol and citric acid, a stable gel structure is formed, which solves the problem of poor stability of traditional micronutrient fertilizers in high calcium and high magnesium systems. This achieves slow-release effect and efficient nutrient release, thereby improving crop yield and quality.

AI Technical Summary
Traditional micronutrient fertilizers are difficult to coexist stably in high calcium and high magnesium concentration systems, have poor solubility, and exhibit antagonistic and synergistic effects between elements, resulting in poor stability and difficulty in achieving effective slow release.
The preparation method of carbomer gel fertilizer adopts a dual chelation process of compound sugar alcohol and citric acid monohydrate to form a stable gel structure, ensuring the synergistic chelation of calcium, magnesium, zinc, boron, iron and molybdenum, and utilizing the thickening and gelling properties of carbomer 940 to form a slow-release effect.
It achieves the stable coexistence of high concentrations of calcium and magnesium, and the function of slow-release micronutrients, improving the stability and utilization rate of fertilizers, reducing precipitation and stratification, enhancing the slow release and absorption efficiency of nutrients, and improving crop yield and quality.
