Analysis of soil nutrients in rubber plantations under stimulated tapping systems in Hainan
Material type:
TextPublication details: Proceedings of IRRDB Conference: NR Industry: Responding to Globalization, 7-8 September 2004, Kunming International Convention & Exhibition Center, China. pp.171-175.Subject(s): Summary: It was analyzed that the soil nutrient contents of 164 soil samples of the rubber plantations under stimulated tapping systems on the main agrotypes in Hainan and it was discussed that the similarities and differences of the rubber plantation soil nutrient of the rubber plantations tapped for lon time under between stimulated tapping systems and traditional tapping systems. According to the result, there was an appraisement of the rubber plantation soil nutrients level now. Under stimulated tapping systems, a large proportion of soil nutient content such as the soil organic matter 60.91;, total N 54.55;, available phosphorus 90.72;, available potassium 62.14;of the all collected samples was lower than that the rubber tree needs, and the soil nutrient content level was discrepant in different agrotypes, and the soil nutrient content could tend to seclining with the timber under stimulated tapping systems. Those could manifest that the nutrient and material recycle of rubber tree itself was changed under stimulated tapping systems.
