| 摘 要： | 不同熟期甘蓝制种组合的播种期试验结果表明：早、中、晚熟甘蓝品种的抽薹率均与低温来临时植株的营养体大小呈正比关系，营养体越犬抽薹率越高；其中早熟甘蓝对茎粗及叶片数量要求最低，中熟甘蓝次之；晚熟甘蓝对植株营养体大小要求最高，各个熟期甘蓝的开花期和播种期基本呈正比关系，即播种期越早，开花期也会随之提早；早熟甘蓝品种制种在江苏句容的适宜播种期为9月5日左右；中熟甘蓝品种制种的适宜播种期为8月25日左右；晚熟甘蓝品种的适宜播种期为8月15～25日。

| Abstract: | The seeding time of cabbage eombinations with diflirent maturities in seed production was tested. The results showed that the bolting rates of early maturing, middle maturing and late maturing cabbage varieties were positively proportional to their vegetation sizes when low temperature came ; and the larger the vegetation size was, the higher the bolting rate was. The ear ly maturing cabbage had the lowest demand for stem diameter and leaf number, followed by middle maturing cabbage. The de mand for vegetation size of late maturing cabbage was the highest. For cabbage combinations with different maturities, the flower ing time was basically positively proportional to the seeding time, namely the earlier the seeding time was, the earlier the flowering time was. In local seed production of cabbage, the suitable seeding time was around September 5 for early maturing variety, about August 25 for middle maturing variety, and August 15 -25 for late maturing variety. |
