摘要
采用田间试验和实验室分析,对黑龙江白三叶(Mini-BL)和2个引进白三叶品种瑞文德、考拉的坪用特性进行了比较,测定了3个品种的物候期、根冠比、越冬率和相对电导率等指标。结果表明:各品种坪用特性之间存在差异,Mini-BL返青早,叶片小,植株低矮,分枝快,观赏期长,能够安全越冬;在抗旱和抗寒性上,Mini-BL与2个引进品种的相对电导率差异显著(P<0.05),抵御逆境损伤的能力强,生态适应性和抗逆性优于引进品种。
Turf characteristics of Mini-BL and other two introduced varieties （Rivendel and Koala） of white clover were studied. Both botany and biological characteristics of them were observed. Their phenophase,root/shoot ratio, overwintering rate, relative conductivity rate were tested. The results showed there were significant- ly different turf characteristics between varieties. Mini-BL has many good turf characteristics with small leaves and lower height,more branches and long viewing period. Mini-BL can survive safely after winter and return to green earlier than others, its cell membrane permeability is lower than other two. It indicates Mini-BL has a strong resistance to adverse environment,and its ecological adaptation is superior to Rivendel and Koala.
