摘要: 全面地揭示了观赏棕榈播种育苗过程中几个关键技术问题,为建立观赏棕榈种苗生产技术规程提供了依据为掌握观赏棕榈植物播种育苗的关键技术,建立高效种苗繁育体系,研究比较了部分观赏棕榈植物种子采后贮藏时间、播种基质、播种方式和幼苗移植期对种子发芽及幼苗的影响。结果表明,棕榈植物种子采后适宜贮藏时间依种子产地而异,采自新加坡的蒲葵和棕竹种子采后即播或短期贮藏(<45d)后播种发芽率显著高于采自福建的种子,而采自福建的种子拌沙湿藏较长时间(>75d)后的发芽率则显著高于采自新加坡的种子;育苗基质以5份椰糠、3份河沙和2份泥炭按体积比配制的混合基质Ⅱ或以5份椰糠和5份河沙按体积比配制的混合基质Ⅰ较好;种子萌发为近距带鞘型的假槟榔和散尾葵可采用地播或盘播育苗,且在1叶期移植幼苗成活率最高,越迟移植成活率越低;而远距无鞘型的伊拉克蜜枣宜采用袋播育苗。研究结果较

Abstract: To grasp the key technology of seed propagation of ornamental Palmae to establish an efficient system for seed breeding, comparative study of some ornamental Palmae adopted seed storage time, planting matrix, planting methods and transplanting period of seedlings on seed germination and seedling growth. The results showed that the appropriate storage time of Palm seed depend on the origin region, seed germination rate of Livistonea chinensis and Rhapis excelsa after harvesting the seeds without storage or short-term storage collected from the Singapore was significantly higher than those collected from the seeds of Fujian, and the germination rate of sand mixed with the wet storage for a period of time collected from Fujian was significantly higher than that collected from the seeds of Singapore. Palm plants suitable for the propagation matrix was mixed matrix No.2 composed the five coconut husk, the three sand and the two peat and mixed matrix No.1 composed the five coconut husk and the five sand. Planting method of palm plants of Archontophoenix alexandrae and Dypsis lutescens used to seedbed breeding or nursery tray breeding, and planting method of Phoenix dactylifera used to nursery bags breeding. But regardless of seedbed breeding and nursery tray breeding, transplanting period of seedlings for one-leaf stage more appropriate, the later of transplanting period of seedlings, the lower the survival rate of seedlings.The results of this study revealed the several technical problems of planting breeding process for ornamental Palmae, provided the technical basis for the establishment of the seedlings technical specification for ornamental Palmae
