Abstract

The invention discloses sterilization-type water-soluble fertilizer and a preparation method thereof, and belongs to the technical field of fertilizer. The sterilization-type water-soluble fertilizeris formed by nutritional base materials and sterilization composite materials according to the mass ratio of 10:1 in a combined mode, wherein the nutritional base materials are prepared from raw materials of urea, monopotassium phosphate, borax and trace elements; and the sterilization composite materials are prepared from raw materials of nano-silver glue, a surfactant, chitosan and a synergist.Basic nutritional substances provide sufficient NPK and trace elements for crop growth to ensure nutrition supply at all stages of crop growth. An effective sterilization compound takes the nano-silver glue and the chitosan as the main sterilization active substances and is supplemented with ingredients such as the surfactant and the synergist, occurrence of plant diseases and insect pests of crops is effectively inhibited, the crop yield is increased, and the crop quality is improved. The fertilizer is scientific in formula, a preparation technology is simple, and wide practical application value is achieved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a bactericidal water-soluble fertilizer and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and the enhancement of awareness of ecological environment protection and self-health protection, people's demand for safe, hygienic and clean agricultural products is also increasing. In particular, the large-scale use of chemical fertilizers and toxic pesticides in agricultural production has caused a large amount of agricultural chemicals to be imported into the farmland, which not only causes the quality of crops to decline, and then affects their commerciality, but also accumulates a large amount of harmful chemicals in organisms through soil and water. And through the food chain into the crops and livestock and poultry, resulting in food pollution, seriously affecting human health. Therefore, reducing the ...
