| 摘 要： | 在甘肃秦王川灌区,通过大田试验研究了调亏灌溉对蚕豆产量的影响及产量构成要素的变化,并对蚕豆籽粒产量、生物产量、收获指数与产量构成要素及产量构成要素之间的相关关系进行了分析。结果表明:苗期或拔节期轻度缺水可增产14.05%和9.09%,节水4.14%和10.92%;苗期、拔节期、开花期、成熟期重度缺水使蚕豆单株粒重较对照分别下降9.5%、9.8%、22.3%和16.0%,百粒重较对照分别下降10.2%、6.0%、3.1%和7.0%,轻度缺水处理的百粒重均高于对照和重度缺水处理;蚕豆以苗期进行水分胁迫对提高收获指数的贡献最大;通过对产量构成因素的分析发现单株粒数、单株荚数和单株粒重是构成蚕豆产量的主要因素。

| Abstract: | Based on field experiment the effect of yield and yield components of broad bean were studied in Qinwangchuan irrigation region by regulated deficit irrigation.In addition,the correlations between the grain yield,above-ground biomass,harvest index and yield components,as well as those among yield components were also analyzed.The result shows: water deficit in seeding or jointing can increase yield 14.05% and 9.09% while saving water 4.14% and 10.92%.High deficit water in growth stages of broad bean can mad... |
