Abstract

The present invention relates to a water-soluble boron fertilizer and a preparation method thereof. The water-soluble boron fertilizer is made of mother liquor of calcium ammonium nitrate and auxiliary agent; wherein, the mother liquor of calcium ammonium nitrate consists of nitric acid, calcium oxide and ammonia; the auxiliary agent consists of boric acid, borax and chelating agent of ethylenediaminetetraacetic acid. In the preparation method, the mother liquor of calcium ammonium nitrate and the auxiliary agent are prepared at first; then the mother liquor of calcium ammonium nitrate is heated in a reactor; the auxiliary agent is put in the reactor and mixed with the mother liquor; the mixture is discharged into a material trough for natural cooling; and the water-soluble boron fertilizer can be prepared after the mixture is cooled, granulated by a pelletizer, dried, screened and packaged.

Description

technical field [0001] The invention relates to a water-soluble boron fertilizer and a preparation method thereof. The fertilizer can not only provide nutrition for crop growth, but also prevent and treat physiological diseases of crops caused by boron deficiency. Background technique [0002] Boron is an indispensable nutrient element for the normal growth and development of crops. Reasonable use of boron fertilizers, especially during the critical period of crop boron demand, can effectively prevent and treat physiological diseases caused by boron deficiency in crops, laying the foundation for high yield and high quality. [0003] Boron in soil is expressed as BO 3 2- The state is absorbed by plants. Boron has a certain effect on the growth of roots, stems and other organs, the development of young meristems and the flowering and fruiting of crops. In addition, boron can accelerate the transportation of carbohydrates in crops and promote the metabolism of nitrogen in cr...
