Problems solved by technology

[0003] At present, the trace element fertilizer products on the market are divided into solid and liquid according to the product form. Most of the solids are mainly inorganic trace elements, which mainly have the disadvantages of poor solubility and low compatibility with other fertilizers. It is difficult to adapt to the current sprinkler irrigation and drip irrigation of water-saving agriculture. demand; liquid products have higher packaging and transportation costs, and lower nutrient content, which increases the application cost accordingly
[0004] In terms of application, there are mainly single application and combined application with other existing fertilizers, especially when combined with other compound fertilizers, there will often be low compatibility and precipitation problems, which will affect the application effect.
Therefore, in actual use, the micro-fertilizer and other fertilizers are mainly prepared in proportion according to the experimental situation and then sold, but this situation is difficult to meet the needs of different soils and different crops

Abstract

The present invention discloses a water-soluble solid organic complexation micro-element fertilizer, and a method for producing the same, which is implemented through a technical scheme as follows, water is added into a reactor to heat, organic complexant EDTA and citric acid are added into the reactor, and any two or more soluble salts containing the microelement of Cu, Zn, Fe, B, Mn and Mo are added into the reactor to complex to obtain. The water-soluble micro-element fertilizer has a good water solubility, it is not only capable of improving soil, complementing microelement balance crops nutrient, gaining manurial effect, accelerating growth, resisting stress, improving the crops yield and quality, at the same time, the micro-element fertilizer is capable of cooperating with other compound fertilizer preferably, especially blending smartly based on the actual need of the land and crops growth conveniently, thus it is capable of convenient to be used greatly.

Description

technical field [0001] The invention relates to a solid micro-fertilizer and a production method thereof, in particular to a water-soluble solid organic complex micro-fertilizer and a production method thereof. Background technique [0002] The application of trace element fertilizers in modern agricultural production has become one of the important technical measures for crops to balance nutrient requirements and obtain high yields. [0003] At present, the trace element fertilizer products on the market are divided into solid and liquid according to the product form. Most of the solids are composed of inorganic elemental trace elements. The main problems are poor solubility and low compatibility with other fertilizers. It is difficult to adapt to the current sprinkler irrigation and drip irrigation of water-saving agriculture. Liquid products have higher packaging and transportation costs and lower nutrient content, which increases the application cost accordingly. [000...
