| 摘 要： | 在棉铃吐絮35%～40%时喷施50%噻苯隆可湿性粉剂,研究其对棉花脱叶和吐絮效果的影响,并对气候因素的影响进行了分析.结果表明:该药剂对棉花具有理想的脱叶效果,用药剂量为150～300g/hm2(有效剂量)时,随用药剂量增加脱叶率提高;该药剂能促进棉铃吐絮,提高霜前花比例;用150～450g/hm2剂量处理,对棉花品质没有影响.温度、日照时数对棉花脱叶速度、脱叶率及吐絮率有一定影响.

| Abstract: | Field experiment was conducted to study the effect on shed leaves and boll open percentage on climatic factors and 50% thidiazuron WP spraying in 35%-40% boll open stage of cotton.The results showed that the shed leaves percentage became higher along with the increase of application rate at the rate of 150-300 g/hm2.The thidiazuron could increase boll open percentage.At the rate of 150-450 g/hm2,the quality of cotton wasn't influenced by thidiazuron.The rate of shed leaves and boll open were influenced by temperature and sunlight hours. |
