摘要
大白菜反季节栽培的主要问题是未熟抽薹。本试验选出的反季节栽培杂交种春大将、高冷地是冬性强、合抱类型的早熟、优质品种。确定大白菜适宜播期是防止未熟抽薹的关键 ,春季气温上升到 12℃以上时 ,露地播种为宜 ,保护地栽培的棚室温度也不要低于 12℃ ,温度愈低 ,抽薹率愈早 ,抽薹率愈高。青鲜素 10 0～ 2 0 0倍液喷洒 2次 。
Im mature bolting is the main problem of Chinese Cabbage in offseason culture. The hybrids Chundajiang and Gaolengdi are early, good quality in off-season culture. It is preferable time for sowing when the temperature is higher than 12℃ in spring. Otherwise, the lower temperature is, the earlier bolting, the higher bolting rate. Spraying 1～2% maleic hydrazide twice can control in mature bolting of Chinese cabbage effectitely.
