11%精甲·咯·嘧菌悬浮种衣剂水稻拌种试验研究

Study on the Rice Seed Dressing Tests with 11% Metalaxyl-M·Fludioxoni·lAzoxystrobin FS

采用11%精甲·咯·嘧菌悬浮种衣剂、35%噻虫嗪种衣剂对水稻进行不同播种量拌种试验。结果表明:11%精甲·咯·嘧菌悬浮种衣剂30 g对水400 g拌稻种25 kg,播种量375 kg/hm^2,产量最高;11%精甲·咯·嘧菌悬浮种衣剂30 g+35%噻虫嗪种衣剂10 g对水400 g拌稻种17.5 kg,播种量225 kg/hm^2,产量第二。根据田间试验,药剂处理过的稻种对立枯病有明显预防作用,并可促使苗壮,增加产量。

Different rice seed dressing amount tests with 11% metalaxyl-M·fludioxonil·azoxystrobin FS and 35%thiamethoxam concentrates were carried out in this paper. Results showed that 30 g 11% metalaxyl-M·fludioxonil·azoxystrobin FS with 400 g water and 25 kg rice seeds, together with seedling amount of 375 kg/hm^2, had the highest output, followed by 30 g 11% metalaxyl-M·fludioxonil·azoxystrobin FS ＋ 35% thiamethoxam of 10 g with 400 g water and17.5 kg rice seeds with seedling amount of 225 kg/hm^2. Based on field test analysis, seeds under pharmaceutical treatment could obviously prevent damping off, promote seed growth and increase output.
