【摘要】 引种到哈尔滨的兰州百合,经过2a的栽培试验表明能抗-40℃的低温而露地越冬。越冬植株生长健壮,开花多,在全光下栽培能顺利完成生活史,而遮荫栽培不利于生长、开花。蒸腾强度测定结果表明兰州百合蒸腾量低,抗旱性强。在开花前1—3d辅助授粉才能结实,但以开花2d前辅助授粉的结实率最高。更多还原

【Abstract】 Lilium davidii var. unicolor introduced into Harbin was demonstrated that it can overwinter in open field under-40℃ by 2-year trials on cultivation. The overwintering plants cultivated in full sunlight can complete its life cycle successfully and grow better and with more flowers, but bad and fewer for those cultivated under shelter. It was indicated from the determination of transpiration intensity that the plant with low transpiration and high drought resistance. Supplementary pollination 1-3 days before flowering resulted in seed-bearing, and the rate of fruiting was highest for 2 days.更多还原
