摘要
在基质栽培条件下,分析比较了8个观赏型白菜品种的形态指标和生理指标,并建立了观赏型白菜的综合评价模型以筛选出适合于家庭园艺栽培的赏食性优良品种。结果表明:(1)形态指标方面,8个试验品种中,‘紫玉'株型较为紧凑细长;其他品种相对松散矮小;(2)生理指标方面,8个品种的差别较大,‘紫油菜'的花青素含量高达1.07 mg/g,显著高于其他品种;‘奶白菜'的硝态氮含量超过1.00 mg/g,超出可食用标准;(3)利用层次分析法(AHP)建立观赏型白菜的综合评价模型分析得出:紫叶类白菜叶片呈现不同程度的紫色,且有一定的反卷,观赏价值明显高于绿叶类,其中,‘紫油菜'和‘紫衣'的观赏等级达到1级,观赏性较强;‘紫油菜'和‘苏州青'的营养品质评分达到1级,营养品质较高;综合两方面评分,‘紫油菜'得分最高,为1.864分,表明该品种优越性最强,较为适合家庭栽培。
The morphological index and physiological index of 8 ornamental Chinese cabbage varieties were analyzed and compared under the condition of substrate cultivation,and the comprehensive evaluation model of ornamental Chinese cabbage was established to select ornamental and edible good varieties for family garden cultivation.The results showed that：（1）In morphological index morphology,＇Ziyu＇ was compact and slender,other varieties were relatively loose and short;（2）In physiological index,there were large differences in the 8 Chinese cabbage varieties.The anthocyanin content of ＇Ziyoucai＇ was significantly higher than other varieties,which was up to 1.07 mg/g;the nitrate nitrogen content of ＇Naibaicai＇ was beyond the edible standard（1.00 mg/g）;（3）The comprehensive evaluation model of ornamental Chinese cabbage which was set up by the analytic hierarchy process（AHP）showed that the leaves of purple cabbage showed different degrees of purple and certain anti-roll,and the ornamental value was significantly higher than those of green leaf cabbages.Among them,the ornamental level of ＇Ziyoucai＇ and ＇Ziyi＇ reached grade 1,with strong ornamental property;nutritional quality of＇Ziyoucai＇ and ‘Suzhouqing＇ reached grade 1,with high nutritional quality;taking the two aspects together,＇Ziyoucai＇ scored the highest with 1.864 points,showing that the superiority of the variety was the strongest and it was suitable for family cultivation.
