杭州地区耐抽薹白菜播期与品比试验

Experiment on the sowing date and variety comparison of bolting tolerant Chinese cabbage in Hangzhou Area

为筛选出适宜在杭州地区春季栽培的耐抽薹白菜品种,引进8个白菜品种分3个播期进行比较试验。试验结果表明,8个品种在春季栽培,都会现蕾和抽薹。四季美、浙研黄玉这两个品种现蕾期较晚、抽薹率较低、收获期薹长较短,表明这两个品种耐低温、耐抽薹性较好。且这两个品种株型直立,紧实度较好,商品性佳,丰产性好,综合表现优良,可以作为春季耐抽薹叶菜品种在杭州地区推广应用。
