【摘要】 作者研究了荷兰24个郁金香品种在郑州自然条件下的生物学特性和引种栽培技术.结果表明,多数品种在砂质壤土中能够正常生长发育,无退化现象.整个生育期为200天左右.最大鳞茎重76克,比引种时增加24克.更新鳞茎平均重34.6克,比引种时增加3.8 克.母鳞茎和子球的繁殖系数分别为4和2—3.休眠期鳞茎贮藏在20—30℃,相对湿度68—94%,通风良好的室内,花芽分化正常,自6月中旬开始到8月中旬结束,历时2个月.更多还原

【Abstract】 The biological characteristics and the techniques of introduction and cultivation in the field of 24 cultivars of Tulipa gesneriand was studied. The results showed that they could grow normally and didn’ t degenerate on sandy loam. The period of growth was about 200 days. Maximum single bulb weighed 76 gram , increasing 24 gram. The new bulb weighed 34.6 graias in average, incressing 2. 8 grams. The rates of reproduction of flowering bulb and steall buld were 4 and 2-3 respectively. The flower bud differentiated normally when the bulb was stored in the well-ventilated room with a moderate temperature of 20-30? and relative humidity of 68-94% from June to August.更多还原
