【摘要】 采用分期播种试验(5℃、10℃、15℃、20℃)研究比较了六个不同休眠级的苜蓿的生长特性和生产性能,结果表明:苜蓿的休眠性与生育期(出苗、返青、开花)、生长速度、再生性、越冬率、产草量关系比较密切。半休眠品种出苗早、生长速度快、再生能力强、产草量高,但返青迟,越冬率较低。休眠级4和5的品种适宜在太原地区种植。更多还原

【Abstract】 The paper studied different seeding date treatments( 5℃、10℃、15℃、20℃) on growth character and yield production of six kind of fall-dormancy alfalfa.The results showed:there was a close relation between growth period(seeding,return green,flowering),growth rate,reproduction,overwintering rate,grass yield and fall-dormancy of alfalfa.The species which with semi-dormancy were early seeding,rapid growth,strong reproduction and high grass yield,but their were low overwintering rate and late return green.The species that the fall-dormancy were 4 and 5 were to be cultivated in Taiyuan.更多还原
