Auxiliary prolonging lasting period of plant foliar fertilizer and preparation method thereof

Abstract

The invention provides an auxiliary prolonging a lasting period of plant foliar fertilizer and a preparation method thereof. The chemical fertilizer auxiliary is composed of the following ingredients in parts by weight: 2-4 parts of straw, 1-2 parts of fly ash, 1-3 parts of attapulgite, 1-2 parts of lignin, 5-10 parts of sodium metaphosphate, 1-3 parts of biochemical potassium fulvate, 2-10 parts of sodium pyrophosphate, 5-30 parts of aminopropyl triethoxy silane and 0.6-1 part of a photosynthesis accelerator. The invention also provides a preparation method of the auxiliary. The auxiliary provided by the invention can improve adhesive capability of the foliar fertilizer on plant leaf surfaces and also can promote photosynthesis of the plant leaf surfaces and shorten a plant growth cycle, and drift, leaching loss and volatilization loss are reduced, so that the aims of prolonging the lasting period and improving nutrient utilization rate are achieved; the main raw materials of the auxiliary provided by the invention are natural and environment-friendly, so that no secondary pollution can be introduced; meanwhile, fertilization dosage and frequency are reduced, labour and cost are saved, and environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizer auxiliaries, and in particular relates to a chemical fertilizer auxiliaries for prolonging the effective period of foliar fertilizers and a preparation method thereof. Background technique [0002] In recent years, both at home and abroad have attached great importance to the production and application of foliar fertilizers. The commercialization of foliar fertilizers in China began in the 1980s. After more than 20 years of development, the production of foliar fertilizers has been greatly developed, from a single component to a compound component, from a large number of nutrients to Trace elements and beneficial elements have developed from inorganic nutrients to organic nutrients, and from mineral nutrients to adding plant growth regulators. The names of foliar fertilizers are diverse and varied, with thousands of types nationwide. [0003] However, due to the immature technology an...

Problems solved by technology

[0004] Existing technologies such as Chinese Invention Authorized Patent Documents, Authorized Notice No. CN 103145494 B, the purpose of this invention is to provide a new type of foliar fertilizer additive, by physically modifying and Chemical modification, increase the number of hydroxyl groups on the surface, dispersion performance and adsorption performance, better adsorb the nutrients of the foliar fertilizer in the micro-nano structure of the auxiliary material, and be fixed by the rough plant leaves, so as to improve the foliar fertilizer in the The adhesion ability on the plant leaf surface can reduce drift, leaching loss and volatilization loss, so as to achieve the purpose of prolonging the effective period and improving nutrient utilization rate. The main raw materials of this invention are natural and environmentally friendly, and will not introduce secondary pollution; times, save labor and cost, and reduce environmental pollution. This technology is in line with the development direction of foliar fertilizers and has great market potential. However, there is still room for improvement in the water retention capacity of the additive on leaves and the effect of promoting leaf photosynthesis.
