摘  要：
采用来自浙江省金衢盆地红壤坡耕地和严重侵蚀退化瘠薄地带的2种土壤,对鸡眼草和美丽胡枝子2种豆科植物进行盆栽实验,比较研究2种豆科植物对贫瘠土壤的适应性。结果表明,在贫瘠土壤条件下,鸡眼草的地上干重﹑叶绿素含量﹑浓度氮﹑浓度磷均极显著高于美丽胡枝子;在正常土壤条件下除浓度磷外,其它理化性状鸡眼草也显著高于美丽胡枝子;在2种土壤条件下,鸡眼草叶绿素含量差异不显著,而美丽胡枝子差异极显著。说明,在贫瘠土壤中鸡眼草较美丽胡枝子具有更强的营养吸收能力,更耐贫瘠。

摘  要：
A comparative study was conducted on adaptability of Lespedeza formosa and Kummerowia striata to seriously corroded soil as oppose to cultivated red soil both with normal watering in a potted environment.The results showed that K.striata had better performance and tolerance to poor soil than that of L.formosa.K.striata had higher biomass of shoot,nitrogen and phosphorus content and leaf chlorophyll content in poor soil than L.formosa,and nearly the same was true in normal red soil except for phosphorus content.L.formosa showed significant difference of chlorophyll content between the soil treatments,whereas K.striata had no difference.The test demonstrated that K.striata had stronger adaptability to poor soil.
