摘　　要：为了提高黔西北地区冬季稻田利用率,寻优稻茬蚕豆免耕栽培技术,采用三因素四水平正交设计方法,以品种、密度、播期三因素为研究对象,研究三因素对蚕豆产量的影响。结果表明:在三因素中,对产量影响最大的是播期(极差R=177.3),其次是品种(极差R=163.5),最后是密度(极差R=134.9)。最高产量的最优组合为品种‘织金蚕豆’、密度35cm×35cm、播期10月28日。In order to improve the utilization rate of northwestern Guizhou region winter rice paddies, by research optimal no-tillage planting technology of broad bean after rice, variety, density and seeding time were taken as research object, orthogonal design method with 3 factors and 4 levels was adopted to study the effect of the three factors on broad bean yield. The results showed that, the greatest impact on yield was seeding time （R=177.3）, followed by the variety （R=163.5）, and finally the density （R=134.9） in the three factors. Zhijin broad bean, 35 cm × 35 cm and October 28th were the best variety, density and seeding time of optimal combination of maximum yield.
