A special fertilizer for corn and its preparation method

Abstract

The invention provides a special fertilizer for maize and a preparation method of the special fertilizer. The special fertilizer for the maize is prepared from components as follows: 35%-45% of urea, 5%-15% of diammonium phosphate, 15%-25% of superphosphate, 10-20% of potassium chloride, 3%-7% of zinc sulfate and 3%-7% organic acid. The special fertilizer for the maize can improve the situation of uneven maize fertilization, has a proper ratio of nitrogen fertilizer to phosphorus fertilizer to potassium fertilizer to zinc fertilizer, helps growth of the maize, can affect synthesis of auxin in plant bodies, catalyzes the photochemical reaction of chlorophyll, and promotes photorespiration of the maize. Meanwhile, the properties of adversity resistance, lodging prevention, low-temperature damage prevention and the like of the maize can also be improved. The special fertilizer for the maize can not only increase maize yield, but also improve the maize quality and economic benefits.

Description

technical field [0001] The invention relates to a special fertilizer for corn and a preparation method thereof, belonging to the field of fertilizers. Background technique [0002] Corn is rich in protein, fat, vitamins, trace elements, cellulose and polysaccharides, etc., and has great potential for developing foods with high nutrition and high biological functions. Corn is a food and feed crop. Among the cereal crops in the world, the planting area and total output of corn rank third after wheat and rice, and the average yield per unit area ranks first. my country's corn cultivation area and total output both rank second in the world. [0003] In the process of corn planting, fertilization is one of the most important agricultural production measures. At present, the principle of fertilization of corn is mostly based on organic fertilizers, re-application of nitrogen fertilizer, appropriate application of phosphorus fertilizer, increase of potassium fertilizer, combined a...

AI Technical Summary

Problems solved by technology

Although only one fertilization is required, the lack of trace elements in the corn formula fertilizer will lead to poor growth, disease and yield reduction of corn. Long-term application of this chemical fertilizer will cause soil degradation and compaction, and reduce soil fertility

In addition, the applicable area of ​​the corn formula fertilizer is also small, so it cannot have corresponding effects when applied in other places
