Special compound fertilizer for peanuts

Abstract

The invention provides a compound fertilizer special for peanuts. The compound fertilizer is prepared from the following raw materials in parts by weight: 12-18 parts of urea, 24-36 parts of mixed phosphate fertilizer, 4-6 parts of sodium tetraborate, 3-4 parts of magnesium sulfate, 5-6 parts of zinc sulfate, 2-3 parts of sodium selenite, 12 parts of monopotassium phosphate, 7.5 parts of potassiumsulfate, 0.09 part of a microbial agent, 6 parts of traditional chinese medicine residues, 14 parts of diatomaceous earth, 4 parts of a soil activating agent and 4-5 parts of peanut germ oil. The compound fertilizer is suitable for peanut germination and ripening stage, and the soil fertility is improved, so that soil organic matters can be increased and root diseases and insect pests can be reduced.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special compound fertilizer for peanuts. Background technique [0002] Peanut is an important food crop and economic crop, and plays an important role in people's livelihood and national economy. Effective use of limited land resources to improve the yield and quality of peanut crops is the direction and eternal subject of people's efforts. [0003] The growth and development of peanuts need to absorb more than 20 kinds of mineral elements, mainly including nitrogen, phosphorus, and potassium, three major elements; sulfur, calcium, magnesium and other macroelements, as well as iron, manganese, boron, and copper. Zinc, sodium and other trace elements. Peanuts require the most nitrogen, followed by phosphorus and the least potassium. In addition, zinc plays a positive role in the synthesis of endogenous auxins such as indole acetic acid in peanuts, and iron is ...

Problems solved by technology

However, during the use of urea, it is easy to lose through volatilization, leaching, decomposition and runoff, resulting in low fertilizer utilization rate. According to statistics, the seasonal utilization rate is only about 30%, which not only causes waste of chemical fertilizers, but also Pollution of air, water, soil and other environments on which human beings depend

[0005] At present, there is a lack of fertilizers that can effectively promote all stages of peanut growth
