摘要:
研究郁金香生长发育与温度的关系,为郁金香的设计和配置提供依据。本实验以15个郁金香品种作为试验材料,主要研究露地栽培时郁金香生长发育与温度变化强度、有效积温的关系。试验结果表明:郁金香植物配置应根据品种的生物学特性和种植方法进行配球。低矮、窄冠幅品种应适当增加种植密度,株型高、冠幅大品种应适当降低用球数量,适度的种植密度能降低种植成本。供试郁金香品种发育阈温度6℃~7℃;以萌芽–开花积温为依据,栽培时通过调控积温,使不同类群的郁金香品种花期保持一致。

Abstract: Studying the relation between temperature and growth provides the basis for designing. Taking 15 species as the test material, this paper is mainly to research the relationship between growth and intensity of changes in temperature and effective accumulated temperature of the relationship in land. The results show that designing should be carried out according to the biological characteristics and planting way. Low varieties should be appropriate to increase the planting density and high varieties should be appropriate to reduce the ball number. Appropriate planting density can reduce the cost of planting. The developmental threshold temperatures of different tulips are among 6˚C - 7˚C; based on sprout-blossom accumulated temperature, through controlling the effective accumulated temperature, the tulip cultivars will flower at the same time.
