摘要
在贵州省兴仁县放马坪草场对9个国内外紫花苜蓿品种进行了田间品比试验,并测定了供试品种的株高、生长速率、物候期、鲜草产量、干草产量及营养物质含量,同时通过对这9个紫花苜蓿品种1个生育期的观测,综合分析了越冬率、株高、再生率、产草量、鲜干比等各项指标。结果得出:在贵州兴仁县表现较好的紫花苜蓿品种是9号多叶王、2号CW787、7号TG7,这些品种在该地区产量较高、适应性较强,适合在该地区推广种植。
A field experiment was carried out on 9 alfalfa varieties at home and abroad in the Fangmaping meadow in Xingren,Guizhou, of which the plant height, growth rate, phenologieal period, fresh yield, hay yield and nutrient content were determined.In addition, based on the observation on one growth period of the 9 tested alfalfa varieties, the indexes of overwintering rate, plantheight, regeneration rate, grass yield and fresh/dry ratio were analyzed comprehensively. The results showed that the alfalfavarieties with better performance in Xingren, Guizhou were No. 9 （Duoyewang）, No. 2 （CW787） and No. 7 （TG7）. Thesevarieties have high yield and strong adaptability in this area, and are suitable for planting and promotion in this area.
