摘要：

为了解不同栽培因素对重庆地区稻茬免耕条件下蚕豆生产的作用，采用四因素四水平正交试验，研究品种、密度、施肥和播期对稻茬免耕蚕豆产量和农艺性状的影响。结果表明：品种是影响其产量形成的最主要因素，不同品种对重庆稻闲田这种高湿环境的适应能力差异极显著(P<0.01)；影响蚕豆株高的主要因素是品种自身的遗传因素和播期因素；密度、品种、施肥均对蚕豆单株粒数有显著影响(P<0.05)；影响蚕豆百粒重主要由品种自身的遗传因素决定。综合考虑，重庆地区稻茬免耕蚕豆的最优措施为：‘苏03021’在10月22日播种，密度为12.7×104株/hm2，施用过磷酸钙450 kg/hm2+尿素75 kg/hm2，此时产量可达2725.2 kg/km2。

Abstract:

In order to define different cultivation factors on the influence of board been in non-tillage rice field, orthogonal design of 4 factors, variety, planting density, sowing date and fertilizer, and 4 application amounts on yield and agronomic traits of board been were studied in no-tillage paddy field experiment. In this research, variety had greater effect on yield. The plant height was determined mainly by genetic factors and sowing date. The grain per plant was determined mainly by variety, density and fertilizer. The 100-seed weight was determined mainly by genetic factors. The optimum factor combination was SU-03021 applied with sown in October 22nd, calcium superphosphate 450 kg/hm2 and urea 75 kg/hm2 under the planting density of 1.27×105 hm2, in these conditions, the yield achieved 2725.2 kg/hm2.
