Special water-soluble fertilizer for high-quality wheat and preparation method thereof

Abstract

The invention discloses a special water-soluble fertilizer for high-quality wheat and a preparation method of the special water-soluble fertilizer, and belongs to the technical field of agricultural fertilizers. The special water-soluble fertilizer for the high-quality wheat is prepared from the following raw materials in parts by weight: 60 to 75 parts of urea, 10 to 20 parts of monoammonium phosphate, 5 to 15 parts of potassium chloride, 1 to 10 parts of iron, 1 to 5 parts of manganese, 1 to 10 parts of boron, 5 to 15 parts of zinc, 1 to 5 parts of copper, 0.01 to 0.1 part of urease inhibitor and 0.01 to 0.1 part of nitrification inhibitor. The prepared water-soluble fertilizer has the characteristics of high dissolving speed, relatively high absorption and utilization rate, multiple nutrients and the like, can be applied to facility agriculture such as spraying, drip irrigation and the like, realizes water and fertilizer integration, improves the utilization efficiency of water andfertilizer, and achieves the effects of saving water, fertilizer and labor; meanwhile, the fertilizer can reduce the damage to soil and the environment caused by long-term use of a large amount of chemical fertilizer. In addition, the method can also be used for foliar fertilizer spraying and soilless culture.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a special water-soluble fertilizer for high-quality wheat and a preparation method thereof. Background technique [0002] my country is a big water-deficient agricultural country, and it is also a country that consumes a lot of fertilizers. The annual consumption of chemical fertilizers exceeds 60 million tons, and the fertilizer utilization rate is only 30% to 40%. Excessive application of fertilizers, especially nitrogen fertilizers, not only directly leads to the reduction of nitrogen fertilizer use efficiency and agronomic efficiency, but also causes huge potential harm to the sustainable development of the environment. After nitrogen fertilizer is applied to the soil, it is seriously lost through leaching, volatilization, denitrification and surface runoff, which leads to a series of environmental pollution problems, such as air pollution, lake w...

Problems solved by technology

At present, the production of water-soluble fertilizers in my country is in a period of great development, but there are many problems in the production and promotion of water-soluble fertilizers in my country: 1. The products have low technical content and uneven quality. The stipulated standards are quite different. Many enterprises hold high the brand of "all water soluble" and produce products such as flushing fertilizer, irrigation fertilizer and water-soluble compound fertilizer that do not meet the national standards, misleading consumers; some enterprises emphasize nutrient content and do not Pay attention to the scientific configuration of nutrient form, efficacy, additives and organic nutrients, so that although the products are water-soluble, the utilization rate of active ingredients is not high; some products produced by enterprises even have side effects

2. The price of water-soluble fertilizer is expensive. The price of water-soluble fertilizer on the market is mostly above 16,000 yuan / t, and the high price is as high as 20,000 to 30,000 yuan / t

3. There are many water-soluble fertilizers for fruits and vegetables, but few water-soluble fertilizers for field crops (wheat, corn)
