摘要
通过2009年和2013年对江城橡胶公司32个生产队橡胶园土壤的两次定点取样分析,研究土壤养分现状及变化趋势,结果表明:江城橡胶公司橡胶园2013年土壤全氮、有机质、速效磷和速效钾养分平均含量较2009年有不同程度的下降,下降幅度分别为7.10%、11.21%、62.66%和10.87%,土壤p H略有上升。目前,各生产队橡胶园土壤速效磷除个别队外,全部低于正常水平;有13个生产队土壤有机质处于正常水平以下;各生产队土壤全氮和速效钾均在正常及以上水平。
The present situation and dynamic change of soil nutrients in rubber plantations were studied by positional sampling and analysis in 32 production teams of Jiangcheng Rubber company during 2009-2013. The results showed that the average contents of total nitrogen（TN）, organic matter（OM）, available P（AP）and available K（AK）decresed by different degree compared with that of in 2009, and the decrese amplitude were 7.10%,11.21%,62.66% and 10.87%, respectively, whereas the soil p H increased slightly from 2009 to 2013.The current contents of AP were below nomal level except Zhonghui team, and there were 13 teams whose soil OM were lower than nomal level. The contents of TN and AK of all the production teams were at a nomal level or above.
