| 摘 要： | 以高秋眠级紫花苜蓿品种赛迪10、杰力和巨能M995为材料,在湖南长沙酸性红壤地区进行适应性比较试验。结果表明:供试紫花苜蓿品种在4~7月可收获鲜草4次,鲜草总产60 666.67~70 666.67 kg/hm2,干草总产12 009.39~12 673.54 kg/hm2,赛迪10和杰力在品质上达到一级苜蓿干草的要求,巨能M995达到二级苜蓿干草的标准,说明这3个紫花苜蓿品种可在湖南酸性红壤地区种植。从生长特性、根系指标、产量和营养品质等方面进行综合评价,认为赛迪10和杰力较巨能M995的适应性更好。

| Abstract: | Using high fall dormancy level alfalfa varieties SARDI 10, Jilly and M995 as materials, the adaptability comparison test was carried out in acid red soil region of Changsha, Hunan. The results showed that the tested alfalfa cultivars can be harvested 4 times from April to July, the fresh grass yield was 60 666~70 666 kg/hm2, the hay production was 12 009~12 673 kg/hm2, SARDI 10 and Jilly reached the level 1 of alfalfa hay in quality requirements, M955 reached level 2 of alfalfa hay in quality requirements. This showed that the 3 alfalfa varieties can be planted in the acidic red soil region of Hunan. Comprehensive evaluation was carried out from the aspects of growth characteristics, root index, yield and nutritional quality, SARDI 10 and Jilly had better adaptability than M995. |
