Preparation method of microelement and macroelement compound water-soluble fertilizer

Abstract

The invention provides a preparation method of a microelement and macroelement compound water-soluble fertilizer. The preparation method of the microelement and macroelement compound water-soluble fertilizer comprises the following raw materials in parts by mass: 12-16 parts of a water-soluble nitrogen fertilizer, 21-24 parts of a water-soluble potassium fertilizer, 17-22 parts of a water-solublephosphate fertilizer, 5-9 parts of a water-soluble trace element mixture, 8-11 parts of alginic acid, 6-8 parts of energy-gathered enzyme, 6-9 parts of a chelating agent and 10-13 parts of wormcast. According to the invention, the chelating state of macroelements and microelements is good; macroelement components are fully chelated through ultrasonic oscillation, microelement components are fullychelated under the stirring effect, and thus the using effect can be improved when the fertilizer is used; and meanwhile the method is simple, clear in step and suitable for being used as a preparation process of the macroelement and microelement composite type powder water-soluble fertilizer. The prepared composite powder water-soluble fertilizer contains macroelements required by plants and alsocontains iron, molybdenum, manganese, boron and copper microelements, so that the water-soluble fertilizer is balanced in nutrition.

Description

technical field [0001] The invention relates to the technical field of water-soluble fertilizers, in particular to a preparation method of a micro-element and macro-element composite water-soluble fertilizer. Background technique [0002] Water-soluble fertilizer is a multi-element compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water, easily absorbed by crops, and has a relatively high nutrient absorption and utilization rate. In particular, it can be applied to facility agriculture such as sprinkler irrigation and drip irrigation. Realize the integration of water and fertilizer to achieve the efficiency of saving water, fertilizer, labor and increasing production. Water-soluble fertilizers have good water solubility, less impurities, low electrical conductivity, and can be easily adjusted in concentration. They have the advantages of fast fertilizer efficiency, high crop absorption rate, simple fertilization, not easy to burn s...

Problems solved by technology

[0004] Most of the large, medium and trace elements required for crop growth and development need to be supplemented by fertilization, except for a small part supplied by soil, air and water. Most of the current fertilizers are water-soluble fertilizers, which are easy to be absorbed by crops and provide nutrients The advantages of relatively high absorption and utilization rate, at the same time, the fertilizer contains sufficient macroelements required for plant growth and trace elements necessary for plant production, which can meet the needs of normal plant growth. At present, water-soluble fertilizer products are mainly powder products and Liquid products, but the preparation process of the existing water-soluble powder fertilizer is cumbersome, and the chelation state of the macroelements and trace elements in the prepared compound water-soluble fertilizer is poor, which affects the use effect of the water-soluble fertilizer, and the function of the water-soluble fertilizer And single effect, can not better meet the needs of crop growth
