Nanometer super composite fertilizer and method for preparing same

Abstract

The invention discloses a nanometer composite fertilizer and the manufacturing method in the chemical industry technique field, which produces the nanometer super composite fertilizer with the nanometer material and the sea fertilizer in place of P, K. The method comprises the following steps: purifying the nanometer material by extracting the effective material from magnesium hydrogen fertilizer, phosphate fertilizer and accelerant; neutralizing by adding N; adding the plant regulator and trace fertilizer; manufacturing different grade nanometer super composite fertilizer. The nanometer composite fertilizer has innocuous, pollution-free, the abundant material, which is fit for the root and leaf, has the good availability ratio, and has no way to estimate the social benefit.

Description

technical field [0001] The invention belongs to the field of agricultural chemical technology. Background technique [0002] At present, "Nitrogen, Phosphorus and Potassium" two-element or three-element compound fertilizers at home and abroad are products developed in the 1960s and 1970s. The technology is backward and the nutrients are monotonous. Long-term use of this formula fertilizer will make the crops "partial eclipse" And prone to insects and diseases, resulting in long-term stagnation in grain production. Furthermore, due to the large amount of phosphorus and potassium used in the fertilizer formula, the resources of phosphate rock and potassium mineral in my country are becoming more and more extensive, and the average annual market volume is less than 15%. The scarcity of raw materials has gradually increased the cost of producing compound fertilizers. On the one hand, it has reduced the manufacturer's already meager profits, and on the other hand, it has indirec...

AI Technical Summary

Problems solved by technology

Fertilizer elements lack internal protection measures, fertilizer nutrient elements are less, fertilizer release time is concentrated, release speed is fast, release loss is large, and fertilizer efficiency is low, resulting in crops that "can't eat when they are young, and can't eat when they grow up"

A large amount of nitrogen, phosphorus, potassium and nutrients are lost in space and rivers and lakes, which wastes resources, manpower and material resources, pollutes the air and the environment, and also reduces crop production.
