不同品种多花黑麦草在扬州的适应性比较

试验采用盆栽方法比较了20个引自日本的多花黑麦草(Lolium multiflorum)品种在扬州地区生产性能方面的差异。结果表明，所有品种第1茬产量均显著高于第2茬和第3茬的产量(P<0.05)，相同品种不同茬次间的产草量差异显著(P<0.05)。Harukaze和Musashi在产量、茎叶比、分蘖数和株高等指标方面较其他品种均有优势，说明这2个品种适宜在扬州地区引种种植.

Adaptability of different varieties of Italian ryegrass in the Yangzhou area

The adaptability of twenty varieties of Italian ryegrass introduced Japan were examined in the Ynagzhou area by a pot experiment.The results of this study indicated that the yield of forage of the first cutting time was the highest among all the varieties,and was significantly higher than that of the second cutting time and the third cutting time(P<0.05).The yield of each variety was significant different among different cutting times(P<0.05).Among twenty varieties,Harukaze and Musashi performed well in yield,stem/leaf,tillers and height,implying that they were better adaptable than other varieties in the Yangzhou area.
