High-efficiency chelated liquid fertilizer

Abstract

The invention discloses efficient chelating state liquid fertilizer. The efficient chelating state liquid fertilizer is characterized by being prepared from the following raw materials in parts by weight: 100 to 120 parts of humic acid, 260 to 300 parts of urea, 200 to 235 parts of monopotassium phosphate, 100 to 120 parts of dextrose, 20 to 35 parts of trace elemental constituent and 50 to 65 parts of potassium hydroxide. The humic acid can promote root development to guarantee that crops can sufficiently absorb required nutrient, the reasonable matching of nitrogen, phosphorus and potassium can provide macroelements required by the crops in the earlier and middle phases, the dextrose can improve the quality of the crops, microelement provides the microelement required by the crops, the nutrient matching is reasonable, nutrient durability is high, the nutrient required by the crops during the earlier and middle phases is combined reasonably, the supplement of required nutrient of the crops is guaranteed on the basis of promoting the root development, the applying is convenient, the labor amount is greatly reduced, and the capacity of absorbing the nutrient of the crops is improved.

Description

technical field [0001] The invention belongs to the technical field of liquid fertilizer formulations, in particular to high-efficiency chelated liquid fertilizers. technical background [0002] The organic fertilizer contained in the fertilizer can effectively promote the formation of soil aggregate structure, enhance soil permeability, improve the soil's ability to maintain and supply fertilizers, make crop plants strong, develop root systems, improve soil water retention capacity, and enhance crop disease resistance. The inorganic fertilizer contained in the fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It plays a very important role in balancing fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops. [0003] The fertilizers in the prior art have improper structure matching, poor nutrient durability and low relative utilization rate, resulting in waste of fertili...

AI Technical Summary

Problems solved by technology

[0005] In view of the unreasonable structure of liquid fertilizers in the current market, low fertilizer efficiency, waste of application, and failure to increase production, the purpose of the present invention is to provide a new type of high-efficiency chelated liquid fertilizer and its preparation and use method. The liquid fertilizer has high content and reasonable structure. , can provide nutrients needed by crops for a long time
