Abstract

The invention relates to a high-concentration liquid boric fertilizer and a preparation method thereof. The preparation method comprises the following steps of: on the basis of taking oil as raw materials, adding the oil, strong base and water into a reaction tank, heating by steam under the stirring state, conducting saponification, cooling, standing for layering, removing higher fatty acid on the upper layer, adding boric acid into a base glycerin solution on the lower layer in proportion, heating and stirring for reaction, adjusting the pH value to be 7-8 by using the strong base, standing, cooling and packaging to obtain the high-concentration liquid boric fertilizer. According to the high-concentration liquid boric fertilizer and the preparation method thereof, the needed raw materials can be obtained simply and easily, the process is simple, the investment and the cost are low, the fertilizer can adapt to the demands of the conventional agricultural production and can be promoted widely. The liquid boric fertilizer prepared by the invention contains 100-110g/L of boron so as to be high in born content, achieves or exceeds the industrial standard of microelement water-soluble fertilizer, and has the advantages of being completely water-soluble, stable in performance, good in blending property and quick in absorption, and widely used for crops, improving the stress resistance of the crops, effectively preventing the phenomenon of boron shortage of the crops, promoting the flowering and protecting fruits, improving the quality and increasing the yield.

Description

technical field [0001] The invention relates to the field of a liquid trace element fertilizer, in particular to a high-concentration liquid boron fertilizer and a preparation method thereof. Background technique [0002] Boron is one of seven micronutrients essential for plant growth and development. Boron is not a component of various organic substances in crops, but it can strengthen some important physiological functions of crops, promote root growth, play an important role in the synthesis and transportation of carbohydrates, the product of photosynthesis, and play an important role in the normal fertilization process. special role. Sufficient supply of boron leads to luxuriant plant growth, plump grains, good root system, and a good harvest; on the contrary, insufficient boron supply leads to poor plant growth, reduced product quality and yield; severe boron deficiency, even grain failure. There are boron-deficient soils in China in the south and north, so the ration...
