摘 要:对海南省东部部分农场PR107和RRIM600不同产量水平的成龄胶园叶片养分分别进行了研究,结果表明,两个品种的高、中、低产胶园叶片养分状况都存有明显差异,PR107品种高产胶园的全氮和全磷显著高于中、低产胶园;RRIM600不同产量水平的胶园中全钾和钙存在显著差异。高产胶园中,PR107和RRIM600品种间叶片养分含量存在显著差异,因此,要因树施肥,合理配比,达到增产的目的。The distribution of leaf nutrient in part of east farm of Hainan province with the kind of PR107 and RRIM600 rubber tree was studied, the result indicated that there was special difference in the kinds of high, secondary and low yield rubber plantation. N and P in high yield plantation of PR107 were higher than secondary and low yield rubber plantation; There was distinct difference of K and Ca in all classes of RRIM600 rubber plantation. In the high yield plantation, the kind of PR107 and RRIM600 had distinct difference. In order to increase the yield of rubber, rational fertilization was needed.
