摘  要:
设置6个不同水平的钾肥处理,对油茶(Camellia oleifera)盛果期营养生长和结实情况进行跟踪调查,结果表明:钾素水平对油茶春梢长度、鲜果产量和叶绿度值的影响在短期内不显著,对春梢粗度、叶面积和鲜果出油率的影响达到了显著水平;所设6个钾素水平中,以K3(K2O 180 g/株)和K4(K2O 240 g/株)处理相对较佳,K3处理可使长林53产量比对照提高51.52%,鲜果出油率提高26.54%;而K4处理可使长林27产量提高139.90%,鲜果出油率提高25.64%。品系是影响油茶产量的重要原因,不同品系对钾素水平的响应也存在差异,在生产实践中养分管理宜分系经营。

摘  要:
Experiments were conducted on different amount of potassium in Camellia oleifera stand in the main producing region in Jiangxi province. Two years of continuous investigation on vegetative growth and fruiting showed that both the K3(K2O 180g/tree) and K4(K2O 240g/tree) treatment had better effect. Fruit yield and percent of oil production increased by 51.52% and 26.54% in Changlin 53 series of treatment K3, while 139.90% and 25.64%n in Changlin 27 series of treatment K4. The result indicated that clone had major effect on fruit yield.
