摘    要:对橡胶-大叶千斤拔复合生态系统和橡胶纯林进行连续3 a的对比观测研究,结果表明在橡胶林里种植大叶千斤拔能促进橡胶生长,橡胶平均基径、平均胸径和平均树高分别比橡胶纯林高出11.0%、9.62%和3.78%.与橡胶纯林相比.混作后土壤含水量的季节变化较为缓和且旱季含水量较高;且0~10 cm和10~30 cm的土壤容重每年分别约下降0.03 g/cm3和0.01~0.02 g/cm3.随着种植年限的增加,土壤中有机质、全氮、全磷、全钾含量都呈现出先降后升的趋势,而在对照中土壤有机质、全氮、全磷、全钾含量均呈现不断下降的趋势.表明混作后植物的生长及土壤养分状况比橡胶纯林都有所改善.

关 键 词:农林复合系统  土壤水分  容重  土壤养分

Abstract:This paper presents the comparison of dynamics on the plant growth,and soil moisture and nutrient between the rubber plantation and rubber-Flemingia macrophylla agroforestry system which was a new constructed agroforestry model.The average base diameter,average diameter at breast height(DBH) and average height of the rubber tree in rubber-F.macrophylla agroforestry system increased by 11.0 %,9.62 % and 3.78 % as much as the rubber plantation,respectively.Moreover,higher soil moisture in dry season and less ...
Keywords:agroforestry  rubber plantation  soil moisture content  soil bulk density  soil nutrient content  Xishuangbanna
