| 摘 要： | 目的]通过田间试验评价供试药剂对水稻的生长调节和增产效应。结果]不同药剂处理第4、5节间长分别为7.4~15.8 cm和15.1~20.9 cm,不施药处理分别为21.0、14.4 cm。75%赤霉酸结晶粉减产39.4%,其他3种供试药剂增产6.2%~14%。结论]430 g/L戊唑醇SC、75%肟菌酯?戊唑醇WG、75%赤霉酸结晶粉和0.02%芸苔素内酯AS能抑制第4节间伸长,加速第5节间伸长,对叶绿素和旗叶叶面积提高不显著,对稻米胶稠度影响显著,能降低垩白度和垩白率,对精米率、直链淀粉等指标无显著影响。

| Abstract: | Aims]The field trials were carried on to evaluate plant growth regulator and yield enhancement of 4 tested pesticides in rice.Results] The length of node 4 and node 5 of the different pesticides treatments were 7.4-15.8 cm and 15.1-20.9 cm,respectively.That of no pesticide treatment was 21.0 and 14.4 cm,respectively.the rice reduced production at the rate of 39.4% with gibberellic acid 75% crystal powder treatment,however the other 3 tested pesticides increased production ranged from 6.2-14.0%.Conclusion... |
