Description
Technical Field
The invention belongs to the technical field of fertilizers, and particularly relates to an instant sterilization type foliar fertilizer and a preparation method thereof.
Background
The nutrient absorption of the foliar fertilizer is faster than that of soil fertilization, so that the nutrient deficiency symptom of crops can be overcome faster, the dosage is small, the nutrient utilization rate is high, and the specific gravity of the absorbed nutrients entering seeds is large, so the foliar fertilizer is trusted by broad farmers.
The method is characterized in that a foliar fertilizer is sprayed after being mixed with a pesticide in order to save labor in the actual planting process, but due to the fact that the fertilizer and the pesticide are different in property, under the condition of unreasonable mixing, part of the foliar fertilizer and the pesticide can be subjected to chemical or physical reaction after being mixed, the fertilizer effect and the pesticide effect can be influenced, even fertilizer damage and phytotoxicity are generated, for example, foliar fertilizers containing boric acid, ferrous sulfate and other components are mostly acidic, copper agents such as copper hydroxide and the like are alkaline, and if the foliar fertilizer and the pesticide are mixed, the reaction is easy to occur, and the using effect is influenced mutually. Meanwhile, after the fertilizer is mixed with the pesticide, phenomena such as precipitation, flocculation or color change, air bubbles and the like can be generated. Secondly, the adding sequence of the pesticide and the fertilizer is also required to be noticed, and as the foliar fertilizer, especially the nutritional foliar fertilizer, exists in the form of ions, the pesticide is easily reacted with the foliar fertilizer due to the excessively high ion concentration, and the foliar fertilizer needs to be matched for use and cannot be used after being reserved. The existing foliar fertilizer has short fertilizer effect, is easy to run off from the hydrophobic surface or be drenched by rainwater, needs to be controlled in use amount, is easy to burn leaves too much, needs to be sprayed for a few times, and is labor-consuming and time-consuming.
