紫甘蓝,别名红甘蓝、紫苞菜、红卷心菜。 生态习性:性喜清凉温和气候但耐低温,高温的性能强。莲座叶的生长和抽薹需求温度较高,为20～25℃,叶球生长适温为15～20℃。对土壤适应性强,但以保水性好、微酸性至中性土壤为宜,喜肥。目前多引种国外品种,如日本的鲁比紫球和中生鲁比紫球,均为一代杂种,前者生长期95～100天。单球重1.2千克,耐热性强,低温期结球性好;后者生育期110～120天、单球重1.6千克,抽薹晚,耐寒性强,低温期结球性好,耐 Purple cabbage, alias red cabbage, purple basil, red cabbage. Ecology Habitat: Habitat, cool and mild climate but low temperature, high temperature performance. The growth and bolting of rosette leaf need higher temperature, 20 ~ 25 ℃, leaf temperature suitable for growth of 15 ~ 20 ℃. Adaptability to the soil, but good water retention, slightly acidic to neutral soil is appropriate, like fat. At present, the introduction of foreign varieties, such as Japan’s Ruby Ruby and Mesozoic Ruby, are a generation of hybrids, the former growing period of 95 to 100 days. Single ball weighs 1.2 kg, heat resistance, good low temperature cocooning; the latter growing period of 110 to 120 days, 1.6 kg single ball, late bolting, cold resistance, good low temperature cocooning, resistance
