High-magnesium boron-rich medium-trace element fertilizer containing polymeric calcium-magnesium-boron molecules, and preparation method thereof

Abstract

The invention belongs to the field of production of trace element fertilizers in agriculture, and particularly relates to a high-magnesium boron-rich medium-trace element fertilizer containing polymeric calcium-magnesium-boron molecules, and a preparation method thereof, wherein the medium-trace element fertilizer comprises the following raw materials by weight: 40-80 parts of a silicon-calcium-potassium-magnesium fertilizer, 10-50 parts of boron mud, 10-30 parts of an initiator, and 0.05-0.1 part of tartaric acid, wherein the initiator is quicklime, the tartaric acid has a heavy metal Pb content of less than or equal to 0.001% and a heavy metal As content of less than or equal to 0.0002%, and the medium-trace element fertilizer contains effective magnesium and effective boron capable of being absorbed by crops. According to the present invention, the high-magnesium boron-rich medium-trace element fertilizer contains citrate-soluble long-acting medium-trace nutrition elements, can meetthe requirements of crops on magnesium, boron and other nutrition at whole life cycle, contains magnesium, boron and other medium-trace nutrition elements capable of being easily and rapidly absorbedby crops and having characteristic of no leaching loss, can meet the nutrient requirements of crops at nutrition absorption peak, and can improve the yield and the quality of crops.

Description

Technical field [0001] The invention belongs to the field of production of trace element fertilizers in agriculture, and in particular relates to a high-magnesium-rich boron-rich trace element fertilizer containing polymerized calcium magnesium boron molecules and a preparation method. Background technique [0002] With the development of my country's agricultural modernization, farmers blindly pursue high yields of agricultural products and use large amounts of nitrogen, phosphorus, potassium and other large-element fertilizers. The trace elements in the soil have not been supplemented for a long time, resulting in serious lack of middle and trace elements. According to the theory of nutrient return and the theory that nutrients are equally important and cannot be replaced, the medium and trace elements that crops need to absorb during the production process are as important as the large elements such as nitrogen, phosphorus, and potassium. Only by supplementing the quantity can...

Problems solved by technology

[0005] For areas lacking medium and trace elements, especially magnesium- and boron-deficient soils in southern leaching regions, the compounding of citric acid-soluble fertilizers such as silicon-calcium-potassium-magnesium fertilizers and boron mud can provide medium and trace elements such as calcium, magnesium, and boron that crops need, but Due to the slow release of nutrient elements in citrate-soluble fertilizers, it cannot meet the needs of crops for nutrients such as magnesium and boron during the peak nutritional demand period. If water-soluble magnesium sulfate or borax is added, it will easily cause nutrient leaching. The medium and trace element fertilizer compounded by magnesium fertilizer and boron mud produces medium and micronutrient elements that are easy to be absorbed by crops and not easy to leaching. It can not only ensure the demand for medium and micronutrients such as boron and magnesium during the peak nutritional demand period of crops, but also provide long-term Efficient boron, magnesium and other medium and micronutrients have become the current technical difficulties
