【摘要】 针对辽宁地区现有苜蓿品种秋眠性强、抗寒能力强但产量低的现状,引进了12个国内外不同秋眠级苜蓿品种进行田间试验,测定其生长第2年各项生长指标。结果表明:从株高和产量角度考虑,秋眠级数为3的爱乐高和柏拉图最适合该环境条件,而草原2号、润布勒等秋眠级较低的品种不适合该环境条件;不同苜蓿品种再生性有较大差异,爱乐高(FD3)、WL323(FD4)再生性较好,LoBo(FD3)再生性相对较弱;综合分析各项指标,表现最好的为爱乐高(FD3),柏拉图(FD3)和WL323(FD4)。综合性状最差的为草原2号(FD1),其余品种的性状表现为中等,部分半秋眠品种也可在辽宁地区安全越冬。更多还原

【Abstract】 The productivity of 12 alfalfa varieties at different level of fall-dormancy was studied in order to provide the basic information for resolving the problem of low yield of alfalfa with strong fall dormancy and winter hardiness in Liaoning Province.The results showed that based on the height and yield,Ailegao(FD3) and Bolatu(FD3) were the most suitable varieties(fall-dormancy was 3) for the environment of research area,meanwhile,Caoyuan No.2(FD1) and Runbuler(FD1) were unsuitable.There were significant differences of regrowth character among different alfalfa varieties.The regrowth ability of Ailegao(FD3) and WL323(FD4) was strong,and that of Lobo(FD3) was relatively weak.Alfalfa varieties with a fall-dormancy level of 3 to 5 could live through the winter in Liaoning Province,and had strong reproduction and high vegetation yield.The best varieties in consideration of comprehensive productivity were Ailegao,Bolatu and WL323.更多还原
