摘  要：
[目的]比较4种成分和含量不同的种衣剂55%旱地龙·噻虫嗪·苯醚·烯肟悬浮剂、37%旱地龙·噻虫嗪·苯醚·烯肟悬浮剂、45%噻虫嗪·苯醚·烯肟悬浮剂和27%噻虫嗪·苯醚·烯肟悬浮剂对小麦增产效果及主要病虫害的防效.[方法]在临汾市旱地小麦田进行种子包衣剂处理小麦的发育和增产及病虫害防效试验.[结果] 4种种衣剂均可显著增加小麦分蘖数、穗数、穗粒数和产量.其中抗旱性种衣剂处理小麦的分蘖数、穗粒数和产量显著高于非抗旱性种衣剂的处理.4种种衣剂对纹枯病防效高于48.76%、病情指数低于2.76、对蚜虫防效高于83.87%.[结论] 37%旱地龙·噻虫嗪·苯醚·烯肟悬浮剂可以作为抗旱和防治主要病虫害的种衣剂在山西省中南部冬小麦旱区应用推广.

摘  要：
[Aims] This study aims to evaluate the effect of four different kinds of seed coating formulations on wheat yield, fulvic acid·thiamethoxam·difenoconazole·enestroburin 55% FS, fulvic acid·thiamethoxam·difenoconazole·enestroburin 37% FS, thiamethoxam·difenoconazole·enestroburin 45% FS and thiamethoxam·difenoconazole·enestroburin 27% FS, and to compare their control effects on sharp eyespot and aphids on wheat. [Methods] The field trials were performed with seed treatment by surveying yield of wheat and control effects on main pests and disease at dry wheat field in Linfen, Shanxi. [Results] The results showed that four seed coating formulations could significantly increase culm per plant, kernel number per spike, 1000-grain weight of wheat and control effects on sharp eyespot and aphids. The culm per plant, kernel number per spike and yield of wheat of two drought-resistant seed coating formulations were significantly higher than two non-drought-resistant seed coating formulations. Four seed coating formulations can effectively control sharp eyespot and aphids. The disease index was below 2.76 and the control effects were above 48.76 and 83.87% on sharp eyespot and aphids respectively. [Conclusions] Fulvic acid·thiamethoxam·difenoconazole·enestroburin 37% FS could be used in dry winter wheat area in south-central of Shanxi.
