Multi-functional fertilizer additive

Abstract

The invention discloses a multi-functional fertilizer additive which comprises the following components in parts by mass: 3-5 parts of ammonium thiosulfate I, 3-5 parts of ammonium thiosulfate II, 5-7 parts of disodium inosinate, 10-12 parts of dicyandiamide, 40-50 parts of microbial fertilizer, 25-35 parts of lignin, 10-20 parts of coal gangue, 10-12 parts of compound fertilizer and 4-6 parts of a trace element. The multi-functional fertilizer additive disclosed by the invention is applicable to the field of chemical fertilizer additives.

Description

technical field [0001] The invention relates to the field of additives, in particular to a multifunctional fertilizer additive. Background technique [0002] In recent years, in order to meet the market demand, various fertilizer manufacturers have increased the production of organic-inorganic compound fertilizers. Humic acid organic matter is added to the fertilizers, which is conducive to improving the fertilizer efficiency and reducing the pollution of inorganic salt fertilizers to soil and soil pollution. The impact of hardening, but the appearance of the fertilizer after adding it is not good, the color is black gray or brown black, and due to poor control of the fertilizer process or long storage time, the fertilizer will undergo crystallization and whitening. For fertilizers with darker colors, the color The comparison changes obviously, and it is not easy to be accepted by the market. Therefore, the market needs an additive that can improve the appearance of fertiliz...

[0002] In recent years, in order to meet the market demand, various fertilizer manufacturers have increased the production of organic-inorganic compound fertilizers. Humic acid organic matter is added to the fertilizers, which is conducive to improving the fertilizer efficiency and reducing the pollution of inorganic salt fertilizers to soil and soil pollution. The impact of hardening, but the appearance of the fertilizer after adding it is not good, the color is black gray or brown black, and due to poor control of the fertilizer process or long storage time, the fertilizer will undergo crystallization and whitening. For fertilizers with darker colors, the color The comparison changes obviously, and it is not easy to be accepted by the market. Therefore, the market needs an additive that can improve the appearance of fertilizers, reduce the effect of inorganic salt crystallization and whitening, and can effectively prevent fertilizer compaction

The additives in the existing market only have a single function, either to prevent fertilizer compaction, or to reduce the effect of devitrification and whitening, or to improve the appearance of fertilizers, but the retention time is relatively short, generally one to two months, Unable to achieve long-lasting effects
