Boron fertilizer and its preparing process

Abstract

The invention discloses a boron fertilizer, which comprises the following parts: 5-50% boric acid, 20-80% sodium tetraborate, 2-10% diboron trioxide and 5-15% boron potahydride, wherein the total weight rate of raw material and catalyst is 100:1-5; each one percent of catalyst is composed of 0.1-0.35% gadolinium chloride, 0.1-0.2% neodymium oxalate, 0.05-0.1% calcium chloride, 0.1- 0.2% barium sulphide, 0.1-0.3% sodium aluminate, 0.1-0.3% sodium phosphate and 0.05-0.2% palladium carbonate.

Description

technical field

[0001] The invention relates to the field of chemical fertilizers in agricultural science and technology, in particular to a high-efficiency boron fertilizer and a preparation method thereof. Background technique

[0002] As one of the nutrient elements necessary for plant growth and development, boron is very important in agricultural production. Among the trace elements necessary for plants, the lack of boron is the most common, and the demand for boron is also very urgent for crops. The survey shows that the severe boron deficiency of cultivated land in our country reaches more than 700 million mu, accounting for nearly 40% of the cultivated land area in our country. If boron fertilizers are not applied on these cultivated lands, most crops will suffer from severe boron deficiency symptoms, such as "heart rot" in beet, "flowers but not fruit" in cotton, and "buds but not flowers" in rapeseed. In addition, there are nearly 500 million mu of cultivated lan...
