Abstract

The invention discloses an adhesive of a dry-powder rice seed coat and a preparation method thereof, and belongs to the technical field of agrochemical auxiliary agents. The adhesive of the dry-powder rice seed coat comprises the following components: hydroxyethyl cellulose, lignin sulfonate and redispersible latex powder; the preparation method comprises the following steps: 1), weighing each raw material; and 2) stirring the hydroxyethyl cellulose, the lignin sulfonate and the redispersible latex powder uniformly, and thus obtaining the adhesive of the dry-powder rice seed coat. The adhesive of the dry-powder rice seed coat can improve the adhesion of chemically active substances and filler in the powdery seed coat and seeds, improve the adhesion uniformity and reduce shedding of the seed coat.

Description

technical field [0001] The invention belongs to the technical field of agrochemical auxiliaries, and in particular relates to an adhesive for rice dry powder seed coating agent and a preparation method thereof. Background technique [0002] Seed coating is a processing technology that evenly and effectively coats the seed coating agent containing pesticides, fertilizers, growth regulators and other active ingredients on the surface of seeds in a certain proportion. Seed coating technology has obvious effects on improving seed emergence rate and preventing crop pests and diseases at the seedling stage, and has the effects of promoting seedling growth, increasing yield, saving pesticide and seed consumption, reducing field fertilizer input and farmland ecological environment pollution. [0003] Currently, seed coatings come in two forms: filmed and pelletized. Due to the limited attachment substances, the coated seed coating agent is not effective in improving the emergence r...
