Multifunctional composite drought resistant water-loss reducer for corn and preparation method thereof

Abstract

The invention discloses a corn multifunctional composite drought-resistant water retention agent and a preparation method thereof. The water retention agent is made from corn flour, polyacrylic acid, polyglycol, an adhesive agent, a salt compound, microelements, agricultural boric acid rare earth and a plant growth regulator which are prepared according to a certain proportion. The preparation method comprises the following steps that: (A) the corn flour and water are added in a container; (B) pasting is carried out at a certain temperature; (C) polyglycol, polyacrylic acid and adhesive agentare added and mixed after pasting so as to generate a gelatinous material; (D) the gelatinous material undergoes reaction in nitrogen gas and then is neutralized by calcium hydroxide; and (E), through graft copolymerization, explosive polymerization, cooling, slicing, drying and crushing, a natural macromolecular graft copolymer is obtained, and then a salt compound, microelements, agricultural nitric acid rare earth and a plant growth regulator are added to carry out crushing and mixing, thereby generating a mixture. The corn multifunctional composite drought-resistant water retention agent has quick water-absorption speed, strong water-absorption capacity, easily implemented method, simple technical process and convenient operation, and is suitable to be used in production in small and medium-sized enterprises.

Description

technical field [0001] The invention belongs to the technical field of soil fertilizer and water-saving agriculture, and more specifically relates to a special multifunctional composite drought-resistant water-retaining agent for corn, and also relates to a preparation method of a corn multi-functional composite drought-resistant water-retaining agent. The technical product can play a role in drought resistance and water retention. It is suitable for popularization and application in corn production in dry areas and southern seasonal dry areas. Background technique [0002] Yield and quality are the comprehensive results of various physiological and biochemical metabolisms of maize. Drought affects various physiological and biochemical processes of maize, which is one of the main limiting factors of maize production in my country. [0003] The drought-affected fields of maize mainly have the following symptoms: ①Drought at the seedling stage, the plants grow slowly, the leav...
