春甘蓝栽培是在冬春阳畦育苗,春季定植,初夏采收,对解决春淡季供应具有重要意义。但在生产中常常发生未熟抽薹而造成严重损失。因此,栽培中应以减少抽薹率为中心,来加强苗床及田间管理。1.选择良种春甘蓝要选择冬性较强,不易抽薹且具有早熟、丰产特征的品种或一代杂种,如中甘21号、津甘8号、中甘18号等。为延长春甘蓝的供应期,亦可选择部分中早熟品种,如中甘17号、中甘15号等。
Cultivation of spring cabbage in winter and spring yang nursery seedlings, planting in spring, early summer harvest, to solve the supply of spring and summer is of great significance. However, in production, it often happens that the bolting process has caused serious losses. Therefore, cultivation should be to reduce bolting rate as the center, to strengthen the seedbed and field management. 1. Select good varieties of spring cabbage to choose a strong winter, not easy to bolting and early maturity, yield characteristics of the varieties or first-generation hybrids, such as Zhong Gan 21, Jin Gan 8, Zhong Gan 18 and so on. In order to prolong the supply period of spring cabbage, some middle and early maturing varieties may also be selected, such as Zhonggan 17 and Zhonggan 15.
