一、春结球大白菜——“87春34” 植株稍直立,外叶绿色。叶球炮弹形,球顶较尖,舒心,单球重1.75 kg,亩产叶球4500～5000 kg,风味良好,综合抗性较强。冬性强,不易未熟抽薹,早熟(播种后60天成熟)。青岛地区宜4月初露地平畦直播,覆盖地膜。早春低温持续较长的年份要适当迟播,以防未熟抽薹。二、耐热大白菜——青研1号(原代号“93E38”) 引进国外耐热试材育成的早熟一代杂种。叶球近椭圆形,淡绿色,球顶平圆,叠抱,单球重1.20 kg,亩产叶球3110～3300 kg。耐热、抗病、早熟、超夏阳,播种后50天左右
First, spring robin Chinese cabbage - “87 spring 34 ” plant slightly erected, the outer leaves green. Leaf ball projectile, the ball tip more comfortable, single ball weight 1.75 kg, yield 4500 4500 kg per leaf, good flavor, strong comprehensive resistance. Strong winter, not easy to bolting, precocious (60 days after sowing mature). Qingdao should openly flat early April broadcast live coverage of plastic film. Early spring low temperature continued to be relatively late to be late, in order to prevent premature bolting. Second, heat-resistant cabbage - Green Institute 1 (the original code “93E38 ”) the introduction of foreign heat-resistant materials bred early generation hybrids. Leaves nearly oval ball, light green, flat dome round, stacked hold, single ball weight 1.20 kg, leaf yield 3110 ~ 3300 kg per mu. Heat-resistant, disease-resistant, precocious, super-Xia Yang, 50 days after sowing
