摘要
在柑桔叶片微量元素中,铁的含量最高,约占微量元素总量的60%,其次为锰、铜仅占8%~9%。柑桔品种间叶片微量元素含量以铁的差异较大,产量、品质指标中以产量和VitC含量的变异较大。柑桔叶片中微量元素含量与产量、品质呈显著正相关。西南山地柑桔园叶片缺锌、锰较普遍,需肥顺序为锌>锰>铁>铜。
The effect of mineral element contentes were investigated and analysed in the leaves of Citrus sampled from different types in Chongqing, Sichuan and Giuzhou from 1993 to 1995. The results showed that the content of iron roughly 60% was the highest among the major element, and manganese was the second, while Cu was about 8% to 9%. Variation among the contents of iron was great; and the yields differed because of different contents of vitamin C. The content of microelements in the leaves was significantly correlated with fruit yield and quality, and its effect was made clear through coefficient analysis. Studies showed that zinc and manganese were generally deficient in the leaves. fertilizers should come in the order of zinc>manganese>iron>Cu.
