Urea sulfate fertilizer additive and preparation method thereof

Abstract

The invention discloses a urea sulfate fertilizer additive, which is prepared from the following raw materials in parts by weight: 2 to 4 parts of amino acid, 2 to 4 parts of organic acid, 2 to 4 parts of low-molecular carbohydrate, 1 to 3 parts of potassium polyacrylate, 5 to 7 parts of fulvic acid, 13 to 15 parts of maltodextrin, 22 to 25 parts of water-soluble starch, 1 to 3 parts of nanometeriron oxide, 1 to 2 parts of nanosilicon dioxide powder, 1 part of zinc citrate, 1 part of sugar alcohol, 2 parts of polyacrylamide, 0.5 part of vitamin B, 2 to 4 parts of anti-blocking agent, 0.5 to 3parts of animal source raw material, 0.5 to 3 parts of plant source raw material, and 1 to 3 parts of pH regulator. The preparation method comprises the steps of mixing the effective components according to the matching ratio, adjusting the pH value, uniformly stirring, smashing, uniformly mixing, and obtaining the urea sulfate fertilizer additive. The urea sulfate fertilizer additive provided bythe invention can meet the requirement of crops on growth elements when being applied independently, and is good for improving a complexing capacity of trace elements when being added into a urea sulfate composite fertilizer, the fertilizer efficiency and the utilization ratio of the urea sulfate fertilizer are improved, and the yield and the quality of the crops is remarkably improved.

Description

1. Technical field: [0001] The invention relates to a urea sulfate fertilizer additive and a preparation method thereof, belonging to the technical field of crop fertilizer additives. 2. Background technology: [0002] Fertilizer additives refer to chemicals used to improve fertilizer performance, promote fertilizer efficacy, decompose residual pesticides, nitrates, and improve soil environment. [0003] At present, for the urea sulfate fertilizer products on the market, the effect of fertilizer application is slow, and the effect at the seedling stage is not significant. Long-term application of compound fertilizers to crops will result in a decrease in organic matter content in crop root soil, especially a decrease in soluble organic carbon content, deterioration of soil micro-ecological environment, and serious root microbial diseases. 3. Contents of the invention: [0004] The technical problem to be solved by the present invention is: to overcome the deficiency of ur...
