在昆明地区对“特高”、“邦德”等7个一年生黑麦草品种第二年的生长速度、产草量、分蘖、茎叶比等进行了比较研究,结果表明:“特高”长势最好,“邦德”、“珍尼”次之,营养生长末期鲜草产量分别为6810.4kg/hm2、6206.2kg/hm2、6131.6kg/hm2。特高生长最快,营养生长早、中、晚3期的生长速度分别为0.63cm/d、0.58cm/d、0.51cm/d,始终显著高于同期的其他品种(p<0.05)。因此,在昆明地区,“特高”可作为短期一年生牧草在生产中推广应用;“邦德”、“珍尼”的生产性能仅次于“特高”,也可以适当推广应用。 The growth rate, yield, tiller, ratio of stem to leaf of the seven annual ryegrass cultivars such as “Tego” and “Bond” in Kunming were compared in the second year. The results showed that the growth of “super tall” The best, “Bond”, “Jenny” followed, the end of nutrition growth of fresh grass production were 6810.4kg / hm2, 6206.2kg / hm2, 6131.6kg / hm2. The highest growth rate was observed in super high and the growth rates of early, middle and late stages of vegetative growth were 0.63cm / d, 0.58cm / d and 0.51cm / d respectively, which were always significantly higher than those of the other varieties in the same period (p <0.05). Therefore, in the Kunming area, “Extra-high” can be used as a short-term annual forage in the production of promotion; “Bond”, “Jane” production performance second only to “extra high”, but also can be properly applied.
