摘要 采用大田试验,研究花期喷施15.0,30.0,45.0,60.0 g/hm~2缩节胺对毛叶苕子主茎长度、收获期秸秆与籽粒产量的影响。结果表明,花期喷施缩节胺可有效抑制毛叶苕子主茎的伸长,降低毛叶苕子的秸秆产量,提高毛叶苕子的籽粒产量;随着缩节胺喷施量的增大和喷施次数的增加,缩节胺抑制毛叶苕子主茎伸长的效果、降低毛叶苕子秸秆产量和提高籽粒产量的效果显著增强,其中,以初花期连续3次喷施60.0 g/hm~2缩节胺处理对抑制毛叶苕子主茎长度的效果最好,连续3次喷施45.0 g/hm~2缩节胺处理的毛叶苕子籽粒产量最高。 The effect of mepiquat chloride(1, 1-dimethyl-piperidinium chloride, DPC)on the stem length of Vicia villosa Roth in the flowering stage and the grain yield were studied. By complete block design, a field experiment was conducted with three spraying times and five spraying quantities(0,15.0, 30.0, 45.0, 60.0 g/hm2). The results showed that the length of stem and the yield of straw decreased with the application of DPC in the flowering stage, whereas the yield of grain increased. These influences of DPC increased with the increasing of spraying quantities and times. Three times spraying and 60.0 g/hm2 DPC application was the best treatment for reducing stem length, while three times spraying and 45.0 g/hm2 DPC application was the best treatment for enhancing grain yield of Vicia villosa Roth.
