| 摘 要： | 以7个不同产量水平橡胶品种的1年龄幼树为材料,研究了橡胶幼树的钙镁营养差异.结果表明:橡胶的产量水平与钙不存在显著相关性,与镁存在极显著正相关(除热研8-79外);在供试的7个橡胶品种中,热研8-79、粤390-1、东方93-114的钙镁含量较其他品种低;随着生长月份的延长,橡胶幼树的钙含量增加且在10月达到最大值,镁含量下降且在11月达到最小值.此外,与不施肥处理相比,施肥处理橡胶幼树叶片的钙含量上升、镁含量下降,其中所有品种的叶片钙含量都极显著增加,叶片镁含量除保亭3406、热研7-33-97的极显著减少外,其他品种差异不显著.

| Abstract: | The difference in mineral nutritional was studied for seven rubber tree cultivars with different yield components.The results obtained were as follow: No significant difference in correlation was found between different yield components and nutrient content in Ca,but had extremely difference correlation in Mg besides ReYan8-79.In the seven varieties,the Ca,Mg content of the leaf in the ReYan8-79,Yue390-1,DongFang93-114 were lowest.In the different months,the change of Ca content was increased and higher in ... |
