Water-soluble calcium-magnesium fertilizer and preparation method thereof

Abstract

The invention relates to a water-soluble calcium-magnesium fertilizer which is prepared from the following raw materials in parts by weight: a calcium-containing raw material, a magnesium-containing raw material, an organic fertilizer, an absorption accelerant, trace elements and water. The water-soluble calcium-magnesium fertilizer provided by the invention comprises completely water-soluble calcium-magnesium elements, can be absorbed and utilized by crops and meanwhile has an appropriate calcium and magnesium ratio; due to addition of the organic fertilizer, the absorption accelerant and thetrace elements, the calcium-magnesium elements in the fertilizer meet synergetic absorption of the calcium-magnesium elements in plant physiology and are promoted by one another to take the effects into play, and together with the organic fertilizer, the absorption accelerant and the trace elements, growth of crops can be promoted, and the yield of the crops can be remarkably increased.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a water-soluble calcium-magnesium fertilizer and a preparation method thereof. Background technique [0002] Calcium is an indispensable nutrient element for the normal growth and development of crops. Rational use of calcium fertilizer, especially in the critical period of calcium-loving crops such as apples, tomatoes, and Chinese cabbage, can effectively prevent and treat crops caused by calcium deficiency. Physiological diseases lay the foundation for high yield and high quality. [0003] Calcium can be used as a bridge between the phosphate radical of phospholipid and the carboxyl group of protein in the biological membrane, thus maintaining the stability of the membrane structure. Calcium is an element that forms the cell wall, and the intercellular layer of the cell wall is composed of calcium pectate. When calcium is deficient, the formation of cell walls i...

Problems solved by technology

[0006] In addition, at present, most of the compound fertilizers containing medium and trace elements on the market simply add inorganic salts or oxides of medium and trace elements into the compound fertilizer. Due to the solidification of the soil and the antagonism between ions, this method often causes The utilization rate of medium and trace elements is low, which cannot effectively solve the above problems
