The chemical fertilizers and pesticides can be suspended above the solvent (abbreviated as the upper suspension method) to speed up the dissolution rate and improve the solution quality. Principle Solutes There are two opposite processes of solution and crystallization in solution. The upper suspension method allows the upper part of the solvent to be placed in the solution. The dissolved particles can be freed from the crystallization under the action of gravity and can be expressed as "undissolved solute --- dissolved solute". It can be seen that the upper suspension has a faster dissolution rate, and the loading body with the upper suspension solute can filter out insoluble impurities, while the conventional law does not have this function. Therefore, the upper suspension method can improve the solution quality. Method This method is applicable to the dissolution of all fertilizer and water-soluble pesticide principles in water application. The method is based on the particle size of chemical fertilizers or pesticides. It is to choose a load body that is both permeable to water and does not leak fertilizer or medicine. The hand-held carrier is immersed in the upper part of the container filled with water (in order to invade the fertilizer or medicine), and the carrier is shaken and oscillated. Generally, the dissolving process can be completed in several minutes. If the time is sufficient, the solute static upper hanging method can be used. The carrier of the fertilizer or medicine is to be contained, the middle point of the cross bar of the mouth of the dry container, and the medicine or fertilizer is immersed in the water and allowed to stand still, usually for 30 minutes to complete the dissolution process. Advantage 1, improve efficiency. After testing, a 1% aqueous solution of copper sulfate was prepared. The time ratio between the upper suspension method and the common method is 1:1.96; in the case of the solute static condition, the time ratio between the upper suspension method and the conventional method is 1:33.85. Dissolve calcium superphosphate, the conventional method is first dubbed the mother liquor, stand still overnight, after insoluble matter (gypsum) precipitation. The clear solution was taken out and diluted for application; while the upper suspension method was dissolved once at a concentration of about 10 minutes, and the plaster was filtered. It can be seen that the upper suspension method can improve the working efficiency. 2, to prevent burning seedlings. The chemical fertilizers or pesticides dissolved in the upper suspension method can ensure that the whole liquid concentration is uniform and there are no impurities. As long as the concentration is suitable and used properly, the burning of seedlings (fat injury or phytotoxicity) can be prevented to ensure the application effect. 3, increase efficiency. The conventional method dissolves pesticides such as copper sulphate and ferrous sulphate, which have slow dissolution rates, and must be broken beforehand or dissolved with hot water. The upper suspension method does not need to break, and can be quickly dissolved with room temperature water, which can save energy costs for breaking the work and burning hot water.
