Soybean specialized water soluble fertilizer and preparation method thereof

Abstract

The invention relates to the technical field of fertilizer, in particular to soybean specialized water soluble fertilizer. The soybean specialized water soluble fertilizer comprises, by weight, 8-12 parts of ammonium nitrate, 15-25 parts of triple superphosphate, 20-30 parts of potassium nitrate, 10-20 parts of potassium sulfate, 18-22 parts of humic acid, 4-12 parts of compound micro-fertilizer,2-8 parts of compound amino acid, 2-8 parts of compound vitamins, 40-50 parts of Chinese medicine liquid and several parts of water. Soybean specialized humic acid water soluble is prepared accordingto soil fertility foundation and fertilizer requirement rules of soybeans, needs of the soybeans for various nutrients are met by evenly distributing water and fertilizer into soil of plant roots, precision fertilization is realized, and fertilizer utilization rate is increased; as is shown in application test results, the specialized water soluble fertilizer can increase the yield of more than 27% when applied to the soybeans compared with the traditional water-soluble fertilizer on the market, quality of the soybeans is remarkably improved, and the produced soybeans are eligible and pollution-free.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special water-soluble fertilizer for soybeans and a preparation method thereof. Background technique [0002] Water-soluble fertilizer is a kind of quick-acting chemical fertilizer. Its basic feature is good water solubility, can be completely dissolved in water, and can be directly absorbed and utilized by the roots and leaves of crops. In water-saving agriculture, the application of water-soluble fertilizers through water-fertilizer integration technology can firstly exert the synergistic effect of fertilizer and water, so that the utilization efficiency of fertilizer and water can be significantly improved. The scientific and moderate development and promotion of water-soluble fertilizers is to meet the needs of standardization of modern intensive agricultural planting and production, to ensure high-yield, high-quality and high-efficiency agricultural products, and to pr...

Problems solved by technology

[0004] Soybean drip irrigation cultivation has become one of the experimental cultivation methods for high-yield soybeans in arid and semi-arid areas. Through the integration of water and fertilizer, it is evenly distributed into the root soil of plants to meet the needs of soybeans for various nutrients, realize precise fertilization, and improve fertilizer utilization. At this stage, there is no special humic acid water-soluble fertilizer that meets the nutrient requirements of soybean growth through drip irrigation. Therefore, a special humic acid water-soluble fertilizer suitable for soybean growth and development needs to be developed to further improve fertilizer utilization, reduce fertilizer consumption and cost, and at the same time Improving crop yield and quality has become an urgent need
