[0004] Rice drip irrigation cultivation has become one of the experimental cultivation methods to achieve high yield of rice 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 drip irrigation rice for various nutrients, realize precise fertilization, and improve fertilizer utilization. At present, there is no special humic acid water-soluble fertilizer that meets the nutrient requirements of rice growth through drip irrigation. Therefore, a special humic acid water-soluble fertilizer suitable for the growth and development of drip irrigation rice is developed to further improve fertilizer utilization and reduce fertilizer consumption and cost. , while improving crop yield and quality has become an urgent need

Abstract

The invention relates to the technical field of fertilizers and specifically relates to a dedicated humic-acid-containing water-soluble fertilizer for drop irrigation rice. The water-soluble fertilizer is prepared from the following raw materials in parts by weight: 15 to 25 parts of urea, 10 to 20 parts of urea phosphate, 8 to 12 parts of triple superphosphate, 10 to 20 parts of monopotassium phosphate, 8 to 12 parts of potassium sulfate, 20 to 30 parts of humic acid, 3 to 9 parts of compound microelement fertilizer, 2 to 8 parts of complex vitamin, 2 to 8 parts of compound amino acid, 20 to40 parts of fermentation liquor and 20 to 30 parts of water leachate. The dedicated humic acid water-soluble fertilizer for the drop irrigation rice disclosed by the invention is prepared according tosoil fertility base and rice fertilizer requirement law, contains varieties of major elements and micronutrient element necessary to the rice, fully meets requirements of rice growth and development,high quality and high yield, meanwhile can effectively improve a soil structure and greatly improves a fertilizer utilization rate. Application test results show that compared with traditional commercially-available water-soluble fertilizers, the dedicated water-soluble fertilizer disclosed by the invention can increase a yield by 10.9% or more when being applied to the rice.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a humic acid-containing water-soluble fertilizer specially used for drip irrigation of rice 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...
