Potato minituber seed coating and preparation method thereof

Abstract

The invention discloses a potato minituber seed coating and a preparation method thereof. The raw material formula of the seed coating comprises, by weight, 12-18% of high-performance cypermethrin, 10-12% of urea, 2-4% of borax, 2-4% of potassium sulphate, 2-4% of zinc sulfate, 0.2-1% of gibberellin, 0.2-1% of indoleacetic acid, 8-15% of assistant components, the balance being water for complement of 100% of the weight. The assistant components comprise, by weight, 3% of a dispersing agent, 3% of a film-forming agent, 2% of a thickening agent, 1% of a Preservative, 2% of an antifreezing agentand 0.5% of a warning coloration material, wherein the dispersing agent is polyvinylpyrrolidone, the film-forming agent is polyethylene glycol, the thickening agent is carboxymethylcellulose sodium, the antifreezing agent is ethylene glycol, the preservative is benzoic acid, and the warning coloration material is alkaline rhodamine. The seed coating can be provided for effective controlling potato soil insects, improving seedling emergence and growth and development of the potato minituber, and ensuring seedling aligning and seedling strengthening.

Description

technical field [0001] The invention relates to a seed coating agent for potato microtubers and a preparation method thereof. Background technique [0002] The use of miniature tubers to produce original potato seeds is one of the important links in the breeding process of virus-free potato seeds. However, miniature tubers generally have problems such as serious damage from underground pests at the seedling stage of the field, high nesting rate, relatively small potato pieces, and insufficient nutrient supply. , resulting in low yields of original potato seeds and high production costs. In response to these problems, the following technical measures are mainly adopted at home and abroad to solve: one is to increase the amount of micro-potatoes per mu by 500-1000 grains to ensure the effective number of plants per mu, resulting in an increase of 150-300 yuan per mu of production cost. The second is to carry out chemical seed dressing to prevent and control underground pests....
