Colorful-film coating agent for sunflower seeds and preparation method thereof

Abstract

The invention discloses a colorful-film coating agent for sunflower seeds and a preparation method thereof, belonging to the technical field of agriculture. The colorful-film coating agent comprises the following raw materials in parts by weight: 1-2% of carbendazim, 1-2% of thiram, 0.1-0.3% of fludioxonil, 0.1-0.3% of metalaxyl-M, 1-4% of a dispersing agent, 1-3% of an antifreezing agent, 0.1-0.2% of a preservative, 1-2% of a thickening agent, 3-5% of acid golden yellow, 0.2-0.8% of carbon black, 8-12% of a film forming agent and 10-15% of pearl powder, with the balance being water. The seedscoated by the colorful-film coating agent are colorful and bright, and the colorful-film coating agent has an extremely low shedding rate, so the commodity of the sunflower seeds used as seeds can beeffectively improved; the colorful-film coating agent has good breathability, and the seeds can quickly absorb water and expand after meeting water; the carbendazim and the thiram can effectively prevent germs on the surfaces of the seeds and protect the seeds and have a good prevention effect on damping-off in a seedling stage; and the fludioxonil and the metalaxyl-M can effectively prevent sclerotinia sclerotiorum and downy mildew, the germination rate and the emergence rate of the sunflower seeds are guaranteed and increased, obtained seedlings have developed root systems, are neat and strong and are improved in stress resistance and disease resistance, and sunflower yield is increased.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a sunflower seed colorful film coating agent and a preparation method thereof. Background technique [0002] Sunflower is one of the four major oil crops in the world, and it was introduced to China around the Ming Dynasty. The main sunflower production areas in China are distributed in the northeast, northwest and north China, and can be expanded to the southwest, central south and east China. But sunflower seeds germinate slowly and irregularly, and have a low germination rate. This will affect the yield of sunflowers. Sunflower seed coating can effectively prevent and control plant diseases and insect pests at the seedling stage, and can promote the growth of seedlings. So sunflower seeds need to be coated to improve the germination rate of sunflowers. [0003] Sunflower seed coating is to evenly coat the seed surface with a seed coating agent containing a certain prop...
