摘　　要：经对引进荷兰郁金香13个品种的园艺学性状和不同生态区鳞茎生长、繁殖的测定,筛选出2个稳定品种和4个尚稳定品种,研制了延长和提前郁金香生育期的措施、栽培技术要点、鳞茎采挖时间和贮藏条件,指出所筛选的稳定品种在天津（华北地区）中度盐碱地上能正常生长发育;郁金香秋播后。当地温降至5℃时覆盖地膜,可延长生根时间3～5d,根量可增加35%,翌春可提早发芽和开花时间7～10d,从而保证花后新鳞茎有50d左右的生育期;控制鳞茎贮藏期的温、湿条件是华北地区繁殖郁金香,防止盲花和退化的关键措施。Observations on horticultural characters and growth and propagation of bulbs in different ecologic regions in 13 tulip (Tulipa gesneriana) varieties introduced from the Netherlands were made and two stable and four less stable varieties of tulip were selected. Practices of forcing into growth and lengthening growth period , cultural techniques, harvesting time of bulbs, and storage conditions of tulip were developed. The results showed that stable varieties can normally grow in medium saline -alkali soil in Tianjin. When soil temperature drops to 5℃ after sowing in fall and the soil is covered with plastic film, rooting period can be lengthened by 3 - 5 days, the number of roots can be increased by 35 percent, budbreak and blooming date can be advanced by 7 - 10 days in spring, and the growth period after blooming for new bulbs can amount to about 50 days. Control of storage temperature and humidity of bulbs is the critical measure for propagation and prevention of blind flower and degeneration of tulip in the region of northern China.
