| Abstract: | The paper deals mainly with the Zn status in rubber growing soils and rubber leaves,and its distribution and effect on the growth,yield and resistence to Oidium disease rubber trees in China.The available Zn in rubber growing soils amounts to 2.07 ppm on average,while the total Zn comes to 250 ppm and 242 ppm in the layers of 0-20 cm and 20-40 cm of the soil in rubber plantation respectively,which is higher than that of all other soils in China.The Zn content of rubber leaves amounts to 32.4 ppm on average,which is higher than that in other rubber growing contries.The Zn level of soils vanes greatly,the maximum total Zn being 33 times the minimum total Zn. |
