摘要
通过在川中地区对4个白三叶品种进行4年的生长适应性研究,并对其物候期、株高、叶片大小、匍匐枝数、产量等进行观测。结果表明,4个白三叶品种都能很好地适应该地区的气候和土壤条件;从物候期来看,‘艾丽斯’的生育期最短,且返青期最早,其次是‘海法’;从农艺性状来看,‘艾丽斯’具有植株高大、匍匐分枝数最多等特点,其次是‘海法’,再其次是‘瑞文德’,最差的是‘那努克’;从干草产量来看,4年平均产量‘艾丽斯’(9950 kg/hm2)极显著高于‘瑞文德’和‘那努克’(P<0.01),显著高于‘海法’(P<0.05)。从田间的表现看来,‘艾丽斯’在4个参试品种中综合表现最佳,是该地区的首推白三叶品种;其次是‘海法’、‘瑞文德’、‘那努克’。
The growth adaptability of four white clove varieties in the center of Sichuan was studied for 4 years and the phenephase, plant height, width and length of leaf,prostrate branch number,yield were examined. The Results showed that four white clove varieties well met the climate and soil condition. ＇ Mice＇ had the shortest growth period and the earliest returning green stage. The next came to ＇ Haifa＇. ＇ Alice＇ had higher plant and the number of creeping branches was the most, and ＇ Haifa＇, ＇ Rivendel ＇ and ＇ Nanouk＇ followed in turn. The aver- age hay yield for 4 years d ＇ Alice＇ was very significant higher than that of ＇ Rivendel＇ and ＇ Nanouk＇ and significant higher than that of ＇ Haifa＇. Conclusively, the comprehensive performance of ＇ Mice＇ was the best and ＇ Halfa＇ , ＇ Rivendel ＇ and ＇ Nanouk ＇ were secondary.
