摘 要: | [目的]探讨含有胺鲜酯或复硝酚钠的3%戊唑醇悬浮种衣剂对玉米出苗率和生长效应的影响。[方法]采用室内盆栽法,研究了3种用量(2、4、8 g/kg种子)的3%戊唑醇悬浮种衣剂、3%戊唑醇.0.5%胺鲜酯悬浮种衣剂、3%戊唑醇.0.5%复硝酚钠悬浮种衣剂对玉米种子萌发率和生长效应的影响。[结果]含有0.5%胺鲜酯或0.5%复硝酚钠的3%戊唑醇悬浮种衣剂在2~8 g/kg种子浓度范围内对玉米出苗率无影响,而不含有任何生长调节剂的3%戊唑醇悬浮种衣剂对玉米出苗率有抑制作用;播后15 d,含有0.5%复硝酚钠的3%戊唑醇悬浮种衣剂对玉米幼苗根长和侧根数的刺激生长作用突出;播后21 d,含有0.5%胺鲜酯的3%戊唑醇悬浮种衣剂对玉米幼苗根长和侧根数的刺激生长作用突出。[结论]不同的生长调节剂对玉米幼苗刺激生长作用的时间存在差异。

Abstract: | [Objective] To study effects of 3% tebuconazole suspension seed coating agent containing amine hexanoate and sodium nitrophenolate on maize seedling rate and growth.[Method] Using indoor pot-culture method,effects of three dosage(2,4,8 g/kg seeds) of 3% tebuconazole suspension seed coating agent,3% tebuconazole 0.5% amine hexanoate suspension seed coating agent,3% tebuconazole 0.5% sodium nitrophenolate suspension seed coating agent on maize seed germination rate and growth were studied.[Result] 3% tebuconazole suspension seed coating agent containing 0.5% amine hexanoate or 0.5% sodium nitrophenolate have no effects on maize seedling rate within the range of 2-8 g/kg,while 3% tebuconazole suspension seed coating agent without any growth regulator have inhibitory effects on maize seedling rate;after sowing 15 d,3% tebuconazole suspension seed coating agent containing 0.5% sodium nitrophenolate have significant effects on maize seedling root length and lateral roots;after sowing 21 d,3% tebuconazole suspension seed coating agent containing 0.5% amine hexanoate have significant effects on maize seedling root length and lateral roots.[Conclusion] Different growth regulator have differences on stimulating time of maize seedling growth. |
