摘　　要：山药是忌氯作物,为指导山药生产、避开氯敏感期、确保优质高效生产,本试验以“大和长芋”为试材,不施氯肥为对照,在山药整个生育期的前、中、后期分别施用等量的氯肥,研究不同氯肥施用时期对山药块茎形态及产量的影响。结果表明,前期施用氯肥能显著增加山药块茎粗、块茎鲜质量及产量,使三者分别增加57.70 mm、870.67 g和3569.75 kg/667 m^2,较对照分别高出2.94%、2.00%和2.00%。因此,氯肥施用时期建议以前期为宜。Chinese yam is a chlorine resistant crop.In order to guide the production,avoid the chlorine sensitive period,and ensure the high quality and efficient production of Chinese yam,the same amount of chlorine fertilizer was applied before,during and after the whole growth period of Chinese yam.Taking"Dahe Changyu"as test material and no chlorine fertilizer as control,the effects of chlorine fertilizer on tuber morphology and yield of Chinese yam were studied.The results showed that,the tuber diameter,tuber fresh mass and yield of early application were significantly increased by 57.70 mm,870.67 g and 3569.75 kg/667 m^2,respectively,which were 2.94%,2.00%and 2.00%higher than the control.Therefore,it is suggested that the application period of chlorine fertilizer should be earlier.
