摘要
杂草一直被认为是农作物的有力竞争者;如今,它们已成为农艺系统中不可分割的一部分,并给作物造成损失。2011- 2012年,在伊斯兰阿扎德大学农学研究农场进行了实地研究,评估了几种后谱除草剂对杂草生长的效果及其对蚕豆生长和产量的影响。处理方法为(1)Basagran SL 48% 1.5 L haG1+Haloxyfop-R-methyl EC 10.8% 0.6 L haG1, (2) Bentazon SL 48% 1.5 L haG1+Sethoxydim OEC 12.5% 1.5 L haG1, (3) Bentazon SL 48% 1.5 L haG1+Fenoxaprop-p-ethyl EC 12% 0.7 L haG1, (4) Imazthapyr SL 10% 0.6 L haG1和(5)Imazthapyr SL 10% 0.4施用POST,在整个作物周期内分别设置无杂草和有杂草发生的两个对照区。实验采用完全随机区组设计。与杂草对照相比,施用除草剂减少了杂草生物量,提高了蚕豆的生物产量和种子产量。在除草剂处理中,用量为0.6 L haG1的imazthapyr使杂草干物质减少98.7%,且该处理的杂草干物质最低。无杂草处理蚕豆生物产量最高,与其他处理差异显著。相比之下,在除草剂中,施用剂量为0.6 L haG1的imazthapyr获得的种子产量最高,但不同除草剂处理之间的种子产量无统计学差异。
Efficacy Evaluation of some Herbicides for Weed Management and Yield Attributes in Broad Bean (Vicia faba)
Weeds have always been considered strong competitors of crop plants; and today, they form an inseparable part of agronomic systems and inflict losses on crop plants. A field study was undertaken at Agronomy Research Farm, Islamic Azad University during 2011-12 to appraise the efficacy of some post spectrum herbicides against weed growth and their influence on growth and yield of broad bean. Treatment consisted of (1) Basagran SL 48% 1.5 L haG1+Haloxyfop-R-methyl EC 10.8% 0.6 L haG1, (2) Bentazon SL 48% 1.5 L haG1+Sethoxydim OEC 12.5% 1.5 L haG1, (3) Bentazon SL 48% 1.5 L haG1+Fenoxaprop-p-ethyl EC 12% 0.7 L haG1, (4) Imazthapyr SL 10% 0.6 L haG1 and (5) Imazthapyr SL 10% 0.4 applied POST, with two control plots weed-free and weed-infested throughout the crop cycle, respectively. The experiment was replicated forth in a randomized complete block design. Compared with the weedy check, application of herbicides reduced weed biomass and increased broad bean biological and seed yield. Among herbicide treatments, imazthapyr with dose of 0.6 L haG1 reduced weed dry matter by 98.7% and the lowest weed dry matter was observed with this treatment. Maximum broad bean biological yield was obtained in weed free check that was significantly different from other treatments. In comparison, among herbicide, maximum seed yield obtained with application of imazthapyr with dose of 0.6 L haG1, however, there was no statistical difference in seed yield among herbicide treatments.
