Liquid boron fertilizer and preparation method thereof

Abstract

The invention relates to a liquid boron fertilizer and a preparation method thereof. The preparation method comprises the following steps of: adding 18 to 22 weight percent of ethanolamine into a container at normal temperature; adding 14 to 21 weight percent of water into the container with stirring; after the solution is dissolved mutually and uniformly, adding 57 to 68 weight percent of boric acid into the container with stirring; stirring the solution for 2 to 3 hours; and standing until bubbles in the solution are eliminated to obtain the liquid boron fertilizer. The preparation method has the advantages of simple and readily available raw materials, normal temperature synthesis, simple process, small investment and wide popularization. The liquid boron fertilizer prepared by the method comprises 10 to 12 weight percent of boron which has high content and has 100 percent water solubility, so the liquid boron fertilizer has the advantages of stable properties, high blending property, quick absorption and capacities of being widely applied to crops, improving stress resistance of the crops, effectively preventing and controlling boron deficiency phenomenon of the crops, promoting blossom and protecting fruits, improving quality and increasing yield.

Description

technical field [0001] The invention relates to a liquid trace element fertilizer, in particular to a liquid boron fertilizer and a preparation method thereof. Background technique [0002] Boron is one of the essential nutrients for plants. Although it is not a component of various organic matter in crops, it can strengthen some important physiological functions of crops. Sufficient boron supply leads to luxuriant plant growth, plump seeds, good root system and high yield; on the contrary, insufficient boron supply leads to poor plant growth and reduced product quality and yield; when severe boron deficiency occurs, even grains fail. Boron especially has a significant effect on increasing yield and improving quality of boron-deficient sensitive crops, such as rapeseed, cotton, peanut, soybean, sunflower, sugar beet, vegetables, fruit trees, etc. [0003] At present, the types of boron fertilizers are relatively complete, including granules, powders and liquids. Granules a...

AI Technical Summary

Problems solved by technology

Granules are mainly used for base application, and powder can be used for foliar spraying, but the solubility is low and the utilization rate is low, while liquid boron fertilizer is highly miscible with water and can be quickly absorbed by plant leaves, greatly improving the utilization of boron fertilizer Rate

However, the existing liquid boron fertilizer not only has low boron content, but also needs to be synthesized by heating, which has high energy consumption and large investment in equipment, so it cannot be widely promoted.
