品种、播期及密度对菜豆产量的影响

Effects of variety, sowing date and planting density on yield of kidney bean

进行不同菜豆品种、播期及种植密度与产量关系试验,结果表明,品种、播种期是影响菜豆产量的主要因素,差异均达极显著水平,播种越早产量越高,种植密度对菜豆产量影响不显著。其中象牙菜豆比泰国8号、双丰3号分别增产2 4 .0 0 %、2 0 .0 2 % ,且综合农艺性状、品质较优,可作为南宁市菜豆标准化、规范化栽培技术选择品种。

The relationships between the yield of kidney bean and its varieties, sowing date and planting density were studied. The results showed the main factors that affect, with very significant level, the yield were varieties and sowing dates. The earlier the plant sowed, the higher the yield harvested, but the effect of the planting density on the yield was not significant. Among the tested varieties, the yield of Ivory kidney bean was 24.00% and 20.02% higher than those of Thailand 8 and Shuangfeng 3, respectively. With fine comprehensive traits and quality, Ivory kidney bean may serve as the variety for standard and mass production of kidney bean in Nanning.
