| 摘 要： | 目的]探讨喷施KH2PO4对花烟草开花的影响,寻求有利于其开花的最佳KH2PO4浓度。方法]以露地盆栽的花烟草为材料,从现蕾开始每隔7d连续7次叶面喷施0%（对照）、0.25%、0.50%、1.00%、2.00%的KH2PO4,观测喷施不同浓度KH2PO4对花烟草开花各项指标的影响。结果]喷施0.50%KH2PO4对花烟草的开花效果最好,即开花数量最多,盛开花朵数量达到238.0朵/株;开花时间和盛花期最长,分别达到96和56.50d。喷施2.00%KH2PO4对花烟草的开花效果最差,对花烟草的花蕾形成和开花有抑制作用。结论]适当喷施KH2PO4对花烟草的开花有促进作用,KH2PO4的最佳喷施浓度为0.50%。该研究为花烟草叶面喷施KH2PO4提供了理论和实践依据。
