Agricultural magnesium hydroxide fertilizer and application thereof

Abstract

The invention belongs to the technical field of agricultural fertilizers and particularly relates to an agricultural magnesium hydroxide fertilizer. The fertilizer is prepared from, by weight, 45-85 parts of magnesium hydroxide, 20-50 parts of magnesium oxide and 15-25 parts of sulfur, wherein the magnesium oxide contains 15-25 parts of water-soluble magnesium oxide. Meanwhile, the invention further provides application of the agricultural magnesium hydroxide fertilizer to preparation of agricultural fertilizers. The agricultural magnesium hydroxide fertilizer has the advantages that the problem that magnesium hydroxide cannot be dissolved in water is solved, the quick-acting and long-acting fertilization efficacy is achieved, water solubility is 6-70%, and the fertilizer is suitable to be directly used as a base fertilizer and used as a raw material to be added in a fertilizer factory. The fertilizer contains multiple types of medium elements and microelements such as magnesium, sulfur, calcium, silicon and iron which are good fertilizer nutrient. Targeted to the characteristic that soil of part of regions is generally acidized, the agricultural magnesium hydroxide fertilizer which is almost neutral and alkalescent with pH ranging from 8 to 10 is provided, acid-base balance of the soil can be regulated, and soil quality can be improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to an agricultural magnesium hydroxide fertilizer and its application. Background technique [0002] Magnesium hydroxide and magnesium oxide are commonly used as sources of magnesium for agricultural fertilizers. However, the existing magnesium fertilizer has the problem of being insoluble in water, which affects the effective absorption and utilization of the magnesium fertilizer, and finally leads to the slow effect of the magnesium fertilizer and a short period of effectiveness. At the same time, traditional magnesium fertilizers are not comprehensive in nutrition, have poor growth-promoting effects, and do not have the function of soil conditioning. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides an agricultural magnesium hydroxide fertilizer with good water solubil...
