水稻种衣剂的开发,长期以来是个难点。随着高技术的发展,2001年我国水稻护苗种衣剂研制成功和推广,为稻种采用包衣技术,预防恶苗病、立枯病、青枯病、绵腐病等开辟了新途径。护苗种衣剂由高效杀菌剂、抗寒剂、生长调节剂、微量元素、增效剂和通透性抗水成膜剂组成,剂型为15%种衣剂,通过一次性包衣处理稻种,即可达到预防苗期病害、健壮秧苗和增产增收效果,具有操作简便、省工、成本低、防效好等特点,受到稻农的欢迎。一、使用技术稻种包衣前应进行除芒和精选,充分清除秕粒、草籽及夹杂物后,每100公斤稻种,用15%护苗水稻种衣剂2公斤,加水0.2公斤稀释约剂后,用机械或人工包衣稻种。配药前,先将种衣剂用力震荡摇匀,与加入的水搅拌均匀后倒入稻种进行包衣。包衣结束后,将种子装入麻袋或编织袋中,贮存干燥3天以上,使药膜干燥牢固,再进行浸种催芽。浸种时,每100公斤包衣过的稻种,加清水100～120公斤,使水层超过稻种,浸种水温保持11～12℃浸
The development of rice seed coating has long been a challenge. With the development of high technology, the successful development and popularization of rice seedling seed dressing in China in 2001 opened up new avenues for the rice seedlings to adopt the coating technology, prevent the emergence of the disease, the blight, the bacterial wilt and the rot disease . Seedling seed coating by the efficient fungicides, cold agents, growth regulators, trace elements, synergist and permeability of water-resistant film-forming agent, the dosage form of 15% seed coating, through a one-time coating of rice Seedlings can be achieved to prevent disease at seedling stage, robust seedlings and the effect of increasing production and income, with simple operation, labor-saving, low cost, good control effect, etc., are welcomed by rice farmers. First, the use of technology Rice should be removed before the addition of Mango and selection, the full removal of noodles, seeds and inclusions, for every 100 kilograms of rice seedlings, with 15% seedling rice seed coating 2 kg, add water 0.2 kg After diluting the agent, the rice seeds are coated mechanically or manually. Before dispensing, the seed coating is shaken vigorously and mixed with the added water and then poured into the rice seeds for coating. After the coating is completed, the seeds are filled into sacks or woven bags, stored and dried for more than three days, so that the film is dried and solidified, and the seeds are soaked and germinated. Soaking seed, every 100 kg of rice seed coating, add 100 to 120 kg of water, the water layer over the rice seed soaking water temperature to maintain 11 ~ 12 ℃ immersion
