【摘要】 本试验于1990和1992年研究了稀土对‘五香’李生长结果、品质的影响及一些生理效应。结果表明,于盛花期、新梢速长期和果实着色前叶面喷施稀土200-800mg／L3次,可提高‘五香’李的坐果率、产量、果实含糖量,降低果实含酸量和单宁含量。同时增加了叶片叶绿素和N、Fe 的含量。更多还原

【Abstract】 The experiments were carried out in 1990 and 1992 to exploit effects of rare earth elements on growth,fruiting and fruit quality of ’Wuxiang’ plum. The results showed that leaf application of rare earth elements (200-800mg/L) respectively in duration of full bloom, fast growth or pre-colouring of fruit could increase fruiting rate, single tree production and sugar content of fruit, whereas acid and tanin content of the fruits were decreased. Meanwhile,leaf chlorophyll and N and Fe content were increased followed with the application.更多还原
