| 摘 要： | 对云南河口垦区99个橡胶树根病区和103个无病区土壤养分检测结果:除两区土壤全氮水平趋于平衡外,根病区土壤养分水平(尤其是有机质、有效磷、交换性钙和镁)均低于无病区,土壤养分水平低不利于橡胶树根系生长,树体抗性降低,可能是根病发生严重的一个原因。

| Abstract: | Determination of soil nutrients in 99 rubber plantations with root disease and 103 of that without disease was carried out in Hekou.The result showed that the content of soil nutrients was lower in diseased plantations than that of in control(soil organic matter,available P and exchangeable Ca/Mg in particular),apart from the total nitrogen.It`s possible to cause the root disease in rubber plantations with less nutrients. |
