Abstract

The invention discloses a water-retention loss-control compound fertilizer and a preparation method thereof. The water-retention loss-control compound fertilizer at least comprises the following raw materials in parts by weight: 5 to 15 parts of monoammonium phosphate; 10-15 parts of potassium nitrate, 10-25 parts of potassium sulfate, 1-5 parts of potassium chloride, 1-5 parts of chitosan, 1-5 parts of a water retention material, 1-5 parts of potassium fulvate, 5-10 parts of potassium silicate, 0.5-1 part of borax, 0.5-2 parts of magnesium sulfate heptahydrate, 5-15 parts of montmorillonite,0.5-2 parts of zinc sulfate heptahydrate, 1-5 parts of ethylenediamine tetraacetic acid and 5-15 parts of diatomite, wherein the water retention material comprises the following raw materials in partsby weight: 40-60 parts of expanded starch, 10-30 parts of sodium polyacrylate, 1-5 parts of polyglutamic acid, 10-15 parts of water-absorbent resin and 5-10 parts of a 5% gelatin solution. The compound fertilizer disclosed by the invention not only has an excellent moisture regulation and control function, but also can continuously supply nutrient substances to plants, so that the growth requirements of the plants are met.

Description

technical field [0001] The invention relates to the technical field of chemical fertilizers, in particular to a compound fertilizer for water retention and loss control and a preparation method thereof. Background technique [0002] Compound fertilizer is a chemical fertilizer containing any two or three of crop nutrient elements nitrogen, phosphorus, and potassium made by chemical methods and / or blending methods. It is the fastest-growing variety among modern chemical fertilizer varieties and has developed in the chemical fertilizer industry. In countries where the fertilizer industry is developing, it has developed into one of the main fertilizer products; in countries where the fertilizer industry is developing, it will be an inevitable trend of development. The purpose of the production and use of compound fertilizer is to meet the requirements of agricultural scientific fertilization, improve the effect of fertilization, develop high-quality and efficient agriculture an...
