Description
Technical Field
The invention belongs to the technical field of agricultural fertilizers, and particularly relates to a special water-soluble fertilizer for high-quality wheat and a preparation method thereof.
Background
China is a large water-deficient agriculture country and a large fertilizer consumption country, the annual consumption of chemical fertilizers exceeds 6000 million tons, and the utilization rate of the fertilizers is only 30-40%. Excessive application of fertilizers, especially nitrogen fertilizers, not only directly results in reduction of nitrogen fertilizer utilization and agronomic efficiency, but also causes great potential harm to the sustainable development of the environment. After the nitrogen fertilizer is applied to soil, the nitrogen fertilizer is seriously lost through leaching, volatilization, denitrification, surface runoff and other ways, so that a series of environmental pollution problems are caused, such as air pollution, lake water eutrophication, red tide phenomenon, soil acidification, underground water pollution and the like, and further the sustainable development of agriculture, society and ecology is seriously influenced. The water and fertilizer integrated utilization pipeline irrigation system timely and properly and accurately conveys fertilizer and irrigation water to root soil of crops according to the requirement rule of the crops on water and nutrients for crops to absorb, realizes synchronous water and fertilizer management and efficient utilization, can improve the water utilization rate to 70-80 percent, and reduces the pollution to the environment, the atmosphere and water bodies and the potential harm to human beings caused by the traditional rough agricultural planting mode.
A Water Soluble Fertilizer (WSF) is a multi-element compound Fertilizer which can be completely dissolved in Water, can be quickly dissolved in Water and can be easily absorbed and utilized by crops. At present, the production of water-soluble fertilizers in China is in a great development period, but the production and popularization of water-soluble fertilizers in China also have a plurality of problems: 1. the product has low technical content, uneven quality and quite far difference between a plurality of water-soluble fertilizers with lower price and the national standard, and a plurality of enterprises take high brands of 'full water-soluble' to produce products such as water flush fertilizer, irrigation fertilizer, water-soluble compound fertilizer and the like which do not accord with the national standard and mislead consumers; some enterprises emphasize nutrient content and do not pay attention to nutrient form, efficacy, auxiliary agents and scientific configuration of organic nutrients, so that the utilization rate of effective components of the product is not high despite water solubility; also products produced by enterprises may even have side effects. 2. The price of the water-soluble fertilizer is high, and the price of the water-soluble fertilizer in the market is mostly more than 1.6 ten thousand yuan/t and is as high as 2.0-3.0 ten thousand yuan/t. According to market survey of Shandong Shouguang, the imported water-soluble fertilizer contains products such as Pruduodan, Germany Kangshangtai and Israel Haimao, and products of enterprises such as Shanghai Fangdian and Shenzhen Botian are provided in China, the highest zero selling value of the imported water-soluble fertilizer exceeds 4.0 ten thousand yuan/t, and the highest zero selling value is generally about 3.0 ten thousand yuan/t. In 2012, the price of the water-soluble fertilizer is slightly reduced, the imported product is 2.2-2.5 ten thousand yuan/t, and the domestic product is 1.8-2.4 ten thousand yuan/t. 3. The special water-soluble fertilizer for fruits and vegetables is more, and the special water-soluble fertilizer for field crops (wheat and corn) is less.
Meanwhile, with the formation of large-scale operation in land circulation, farmers in large-scale operation would be more willing to accept novel, economical and efficient water-soluble fertilizers. The new technology and the new fertilizer have more and more obvious effect on improving the per capita income of growers. They would like to directly connect with technicians and have the ability to buy drip irrigation and sprinkling irrigation equipment to realize water and fertilizer integration. Therefore, the water-soluble fertilizer becomes one of effective ways for ensuring the sustainable and efficient development of agriculture, and is one of the main directions of the future fertilizer development.
In conclusion, the invention designs the special water-soluble fertilizer for high-quality wheat.

In some of these embodiments, the nitrification inhibitor is at least one of dicyandiamide (DCD) and 3, 4-dimethylpyrazole phosphate (DMPP).
The invention also provides a preparation method of the special water-soluble fertilizer for high-quality wheat, which comprises the following steps: according to the formula requirement, directly and uniformly mixing urea, monoammonium phosphate, potassium chloride, iron (FeEDTA), manganese (MnEDTA), boron, zinc (ZnEDTA), copper (CuEDTA), urease inhibitor and nitrification inhibitor.
In some embodiments, the mixing is physical mixing using a ribbon single-shaft horizontal mixer, a twin-shaft horizontal mixer, or a twin-screw conical mixer.
Compared with the prior art, the invention has the beneficial effects that:
firstly, the method comprises the following steps: the invention has the advantages of wide raw material source, good water solubility, quick nutrition and quick effect and reasonable price.
Secondly, the method comprises the following steps: high-quality wheat refers to wheat with higher nutritional quality and processing quality, the protein content of grains is one of important indexes for quality evaluation, and nitrogen is an important component for synthesizing protein. Therefore, according to the characteristic that the nitrogen demand of the high-quality wheat nutrients is high, the nitrogen-phosphorus-potassium ratio is reasonably set, and the wheat yield and the protein content are improved.
Thirdly, the method comprises the following steps: the invention supplements medium trace elements, has diversified nutrition and chelate trace elements, is beneficial to the absorption of wheat, promotes the growth of the wheat and improves the quality and the yield of the wheat. The zinc can improve the development quality of the root system and the tiller of the wheat, prolong the effective functions of leaves, promote the accumulation of dry matters, increase the spike number and the grain weight and increase the protein content of grains; can also improve the stress resistance of wheat, such as drought resistance, pit low temperature resistance or frost resistance. Iron and copper are important trace elements in the growth and development process of wheat, and play an important role in the redox processes of respiration, photosynthesis, nitrogen metabolism and the like. Iron and copper can promote the growth and development of wheat and improve the yield of wheat. Manganese has a divalent combination form and a trivalent combination form in a plant body and plays an important role in the oxidation-reduction process in the wheat body. Manganese can obviously improve nitrogen absorption, increase the grain weight of ears, thousand grain weight and yield, and can also improve the quality of wheat grains. Boron can promote tillering and ear development of wheat and improve maturing rate, thereby improving the yield of wheat.
