Problems solved by technology

Although the application of boron and potassium single elements can also play a certain role, the absorption and utilization of boron and potassium are not high, and it is a waste of labor.
At present, the boron-potassium compound foliar fertilizers used in our country are all imported from abroad. The imported boron-potassium compound fertilizers are expensive because of the expensive raw materials such as boron sources and additives, and the complex production process, so the products are expensive. Can be popularized and applied in some high value-added crops

Abstract

The invention relates to a potassium decaborate fertilizer and a preparation method thereof. The method comprises the following steps: a polymerized potassium boron salt potassium decaborate as the main component is prepared by high temperature polyreaction between potassium chloride, potassium bromide, potassium fluoride, potassium iodide or potassium hydroxide and boric acid; the polymerized potassium boron salt is then processed and compounded to prepare the potassium decaborate fertilizer. The product of the invention can be widely applied to various crops.

Description

1. Technical field [0001] The invention relates to a crop fertilizer, more specifically a potassium decaborate fertilizer and a preparation method thereof. 2. Background technology [0002] Since the 1960s, my country's chemical fertilizer industry has been greatly developed. Macronutrient fertilizers nitrogen, phosphorus, and potassium fertilizers, trace element fertilizers boron, zinc, iron, molybdenum fertilizers, compound (combined) fertilizers, and organic-inorganic compound fertilizers are widely used in my country. It has been widely used in agricultural production and has effectively promoted the development of agricultural production in our country. [0003] Boron is an essential nutrient element in the life activities of crops. First of all, boron participates in cell division, and boron deficiency manifests as very slow growth of the apical meristems of plant roots and aboveground parts (branches, leaves), which leads to a sharp decrease in the absorption of phosp...
