Production method of chemical fertilizer accessory ingredient for prolonging leaf fertilizer lasting period

Abstract

The invention aims at providing a novel leaf fertilizer accessory ingredient. A production method of the leaf fertilizer accessory ingredient is as follows: natural nano material compounds such as straw ash in a power plant are physically and chemically modified, so that the surface hydroxyl number is increased, and dispersion performance and absorption performance are improved, the leaf fertilizer nutrient is preferably absorbed by a micro nano structure of an accessory ingredient material and fixed by a coarse plant leaf, the adhesive ability of the leaf fertilizer on the plant leaf is improved, the drifting, eluviation loss and volatilization loss are reduced, the aims of prolonging lasting period and improving the nutrient utilization are achieved. According to the method, the main raw material is natural and environment-friendly and is free from the secondary pollution; and meanwhile, the fertilization dosage and the fertilization times are reduced, the labor and the cost are saved, and the environment pollution is reduced. The technology conforms to the leaf fertilizer development direction and has great market potential.

Description

technical field [0001] The method relates to a production method of a chemical fertilizer adjuvant for prolonging the effective period of foliage fertilizer, and belongs to the field of chemical fertilizer production. Background technique [0002] Foliar fertilizer is a type of fertilizer in which nutrients are applied to the surface of crop leaves to exert their functions through the absorption of leaves. Studies have shown that the nutrients sprayed on the plant surface can be absorbed into the plant through the stomata of the plant leaf and the "gap" in the cuticle, and then transformed and utilized. There are many tiny stomata on the surface of plant leaves, which not only perform the function of gas exchange, but also facilitate the entry of nutrients, and are the main channels for plants to absorb foliar fertilizers. In addition, the cuticle of the leaf surface is composed of a long carbon chain fatty acid polymer with hydroxyl and carboxyl groups. The molecular gap o...

Problems solved by technology

[0004] However, due to the immature technology and technology, the foliar fertilizer has insufficient adhesion on the plant leaf surface, and the nutrients sprayed on the plant surface are easy to drift, leaching and volatilization under the action of wind, rain and sun. , resulting in serious fertilizer loss, short duration, low utilization rate, and repeated application, which not only wastes a lot of manpower, material and financial resources, but also causes environmental pollution

Therefore, one of the development directions of the foliar fertilizer industry is to improve the foliar adhesion and prolong the effective period. However, there are few reports on this technology at present.
