摘要: 通过在攀西干热河谷区的小区试验,研究了6个银合欢品种在干热河谷区生长的适应性。并测定和比较了2年生银合欢林地和相应荒地的土壤剖面性状及养分含量。结果表明:供试品种1号、2号和4号生长好,生物量高,而3号、5号和6号未能渡过旱季而枯死;银合欢种植2年后,土壤剖面性状发生了明显演变,有机质含量,全量和速效氮磷钾含量以及阳离子交换量均显著或极显著地高于相应的荒地土壤。

Abstract: The adaptability of 6 Leucaena varieties in the hot-arid region was studied by trial experiment. The feature of soil profile and the contents of soil nutrients were determined after 2 years plantation of leucaena. The results indecated that 3 of the 6 leucaena varieties tested were adaptable in the hot-arid region;the soil fertility was significantly improved in comparson with the none leucaena planting soil.
