| 摘 要： | 对苇状羊茅不同氮磷钾水平及数量性状和产草量的相关性进行了研究。结果表明:氮对产草量的影响最大,在5个数量性状中,株高、茎高、叶数、叶长4个性状与产草量呈显著或极显著正相关,其中茎高和叶长对产草量的作用较大,其它性状通过茎高和叶长对产草量的间接作用也较大,在苇状羊茅高产栽培中,茎高和叶长是重点调控对象,应围绕茎高和叶长的调控目标制定高产栽培技术措施。

| Abstract: | Qiancao 2,a new forage variety,was tested to investigate the correlation between its quantitative characters under different N,P and K levels and green grass yield.The results show that the N level has the most important effect on green grass yield,and there is a significant positive correlation between plant height,stem height,leaf number,leaf length and green grass yield,in which,the stem height and leaf length have great effects on green grass yield.The cultivation techniques for higher green grass yield of Qiancao 2 should pay more attention to characters of stem height and leaf length. |
