摘要
为了探明狼尾草对江苏沿海滩涂盐碱地的适应性,测定了所引进的17种杂交狼尾草的株高、分蘖、直径、鲜草产量、茎叶比等5个性状。结果表明:17种杂交狼尾草品种之间差异较大,其中C11株高最高,与C4、C5、C10、C14等5品种间差异不显著(P>0.05);C1、C2、C3、C7、C9的平均分蘖数明显高于其余品种(P<0.05);17个品种杂交狼尾草的平均直径为1.37～2.26cm,其中C10平均直径最大,与C2、C3、C6、C8、C11、C12、C14、C17差异不显著(P>0.05),C11和C12鲜草总产量最高,两者间差异显著(P<0.05),且与其余15个品种差异显著(P<0.05);C10、C11的茎叶比在1.4左右,两者间差异显著(P<0.05),且与其余15个品种差异显著(P<0.05)。综上,C11、C12适宜在江苏沿海滩涂生产推广。
To study the production traits of Hybrid Pennisetums in Jiangsu Coastal Beach Saline-alkali, 17 Hybrid Pennisetums were planted and researched from 5 traits such as height, tillering, diameter, fresh grass yield and stem/leaf ratio in this test. The results showed that there were great differences among 17 Hybrid Pennisetums, the height of Cll was the highest, and had less differences among C4, C5, C10, C14 the average tillering numbers of C1, C2, C3, C7, C9 were more than the other varieties（P〈0.05）; the average diameter of 17 varieties were among 1.37-2.26cm, and C10 was the thickest, and had less difference among C3, C6, C8, Cll, C14, C17, and had significant difference with the other 10 breeds（P〈 0.05）. the yield of Cll, C12 were the highest, and there was significant difference between Cll and C12 （P〈0.05）, and they had significant difference with the rest 15 breeds（P〈0.05）s; the stem/leaf ratio of C10 and Cll were about 1.4, and there was significant difference between C10 and CI（P〈0.05）1, and they had significant difference with the rest 15 breeds（P〈0.05）. In summary, Cll, C12 were suitable to promote the production in Jiangsu coastal beach.
