Chelating type multielement composite plant nutritive liquid and its preparation method

Abstract

A chelated composite multi-element nutritive liquid for plant is prepared from 16 raw materials including N fertilizer, potassium dihydrogen phosphate, magnesium salt, copper salt, vitamines, etc through proportionally mixing, heating, stirring, filtering, and diluting. Its advantages are high utilization rate of its active components, high effect, durable action, preventing and eliminating diseases of plant, and increainsg yield.

Description

technical field [0001] The invention relates to the field of compound fertilizer production, in particular to a chelating type multi-component compound plant nutrient solution capable of improving crop yield and quality and a preparation method thereof. Background technique [0002] For a long time, my country's agriculture has used a large amount of nitrogen, phosphorus, and potassium fertilizers to increase the yield of crops. With the increase in yield, crop fruits have taken away more and more trace elements, making the lack of trace elements in the soil more and more serious. According to soil survey data, most areas in my country have varying degrees of trace element deficiency. In order to change the traditional farming methods, fertilize in a planned way, change the method of application and balance the fertilization, improve the agricultural ecological environment and the difficult problems such as environmental pollution and fruit odor caused by the large-scale appl...
