提要本试验探讨了甘蓝不同品种、不同播种期对先期抽苔及产量的影响。结果表明:不同品种、不同播期对先期抽苔率的影响达极显著水平;同一品种不同播期的先期抽苔率也达极显著水平。不同品种对产量影响达极显著水平,而不同播期对产量影响不显著。春甘蓝的适宜播期为10月下旬,通过提前播种的方法筛选不易先期抽苔的春甘蓝品种是行之有效的。
Abstract This experiment explored the effects of different varieties and different sowing dates on bolting and yield of cabbage. The results showed that the effects of different varieties and sowing dates on the early moss rate were extremely significant. The earlier moss rate of the same variety sowing dates reached extremely significant level. The effects of different cultivars on yield were significant, while the effects of different sowing dates on yield were insignificant. Suitable sowing date for spring cabbage is in late October. It is effective to select the spring cabbage varieties which are not easy to be bolted by the method of early sowing.
