Abstract

The invention discloses mineral source chelated citric acid soluble particles and a preparation method thereof. The mineral source chelated citric acid soluble particles are prepared from the following components in parts by weight: 20-40 parts of calcium magnesium phosphate fertilizer, 20-30 parts of citric acid, 20-30 parts of humic acid, 20-25 parts of silicon dioxide, 5-10 parts of sulfur, 10-15 parts of zinc sulfate heptahydrate, 2-5 parts of boron oxide, 0.01-0.1 part of manganese sulfate, 0.01-0.1 part of copper oxide, 0.1-1 part of ferric oxide, and 0.01-0.1 part of molybdenum sulfide.Various medium and trace elements in soil can be comprehensively supplemented and balanced, the soil is healthier and more fertile, benign growth of crops is promoted, and therefore the yield and quality of the crops are improved. The particles can improve soil fertility and effectively promote absorption and utilization of macroelements such as nitrogen, phosphorus and potassium. The total product prepared by the method is chelated citric acid soluble particles, has a good slow-release effect, and can improve the soil quality for a long time.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a mineral source chelated citrate soluble particle and a preparation method thereof. Background technique [0002] The elements needed for crop growth are not limited to nitrogen, phosphorus, and potassium. Simply using a large amount of nitrogen, phosphorus, and potassium cannot achieve the highest yield and good quality of crops. Scientific fertilization and balanced fertilization are important means to improve crop yield and quality. In recent years, with the extensive use of nitrogen, phosphorus and potassium compound fertilizers, the supplementation of medium and trace elements has been neglected. Therefore, the recent large-scale application of large-scale elemental compound fertilizers cannot further increase the yield of crops. On the contrary, crop diseases and insect pests continue to appear, and land and water sources are seriously polluted. The compound fertilizer of prio...
