| 摘 要： | 雨水于1981到1982年在3个地区收集,2种橡胶林内雨于1982年1月到1983年4月在景洪收集。分析结果表明:雨水中N、P、K、S、Ca、Mg的含量分别为17.3～19.9、0.22—0.50、11.0—15.2、9.2—27.6、3.0—18.9、6.7—12.3公斤/公顷·年;橡胶林内雨上述元素的含量分别为15.2—18.1、1.23—1.44、16.6—24.9、11.0—17.4、16.6—18.6、14.0—15.8公斤/公顷·年。降雨和橡胶林内雨的养分含量随一年中降雨量的变化而呈现明显的季节变化,一般雨季初最高,雨季次之,冬、早季最低,与本区橡胶树的生长节奏相一致。

| Abstract: | Rainwater was collected from the three different sites of Xishuangbanna in 1981 and 1982. The throughfall in two types of Hevea was collected from Jinghong in Jan. 1982 to Apr.1983. The analysis indicated that the amounts of N, P,K,S,Ca and Mg in the incident rainfall were 17.3-19.9, 0.22-0.50, 11.0-15.2, 9.2-27.6, 3.0-18.9 and 6.7-12.3Kg/ha/year respectively.The amounts of these elements in the Hevea throughfall were 15.2-18.1, 1.23-1.44, 16.6 -24.9, 11.0-17.4, 16.6-18.6, and14.0-15.8, Kg/ha/year respectiv... |
