Problems solved by technology

[0004] At present, the common controlled-release fertilizers for peanuts are mainly based on sulfur-coated nitrogen fertilizers, resin-coated nitrogen fertilizers, and adding silica-calcium soil. However, the slow-release of sulfur-coated nitrogen fertilizers is unstable and requires high production safety; resin The cost of coating is high, and the material is not easy to degrade, which leads to secondary pollution; other peanut fertilizers mainly increase medium and trace elements, emphasizing the nutritional effect

Abstract

The invention relates to the technical field of special fertilizers for crops, in particular to a special controlled-release fertilizer for peanuts and a preparation method thereof. The peanut-specific controlled-release fertilizer includes A component and B component; the A component is hyperbranched polyphosphoramidite-coated large-grain urea, and the B component is hyperbranched polyphosphoramidite-coated second premixed material; the second premix includes a characteristic function package and the first premix; the characteristic function package includes dual-source humic acid, soil conditioner, fungicide, inorganic fertilizer, and the first premix includes dual source humic acid, inorganic fertilizers, fillers; the preparation method of the special controlled-release fertilizer for peanuts is simple and easy; the special controlled-release fertilizer for peanuts uses biodegradable multi-branched Hyperbranched polyphosphoramidate and dual-source humic acid based on low-molecular-weight polychelate are used as slow-release materials to meet the characteristics of peanuts with fewer ends and more fertilizers in the middle. At the same time, it is equipped with special function packages to improve peanut quality and yield.

Description

Technical field [0001] The present invention relates to the field of special fertilizers in crop, in particular to a dedicated controlled release fertilizer for peanuts and a preparation method thereof. Background technique [0002] Peanuts is crops with higher oil crops, and the oil output rate is as high as 45% ~ 50%, and the oleic acid in peanut is more than 50%, which has the effect of reducing high blood lipids and harmful cholesterol in the human body. [0003] The North is covered with cultivation technology, anti-low temperature spring drought, promotes peanut growth and development, improves the quality of peanuts, and improves premature birth. Peanut growth, the number of rantroms, weak nitrogen, neutral fruit needle, should not be fertilized, so peanuts are important, generally in the pre-planting of fluttering, one-time fertilizer, to meet the full growth period Demand of fertilizer. [0004] At present, the common peanut controlled release fertilizer is mainly based ...
