　　为及时掌握春旱对滩涂盐碱地上杂交狼尾草农艺性状的影响，筛选较为适宜在滩涂盐碱地种植的品种，对引进栽植的13个杂交狼尾草品种进行测试，主要从株高、分蘖数、叶片数、叶长、叶宽、直径等6个性状对其在盐碱地的农艺性状进行研究。结果表明：滩涂春季干旱让杂交狼尾草的株高受到了严重的影响，E-6、E-9、E-10、E-11的平均高度均超过了90 cm，其中E-9与其余9个品种差异显著（P＜0．05）；E-11、E-4平均分蘖数超过10个与其余11个品种差异显著；平均叶片数均在10～14之间，除E-10外，其余12个品种间差异不显著；E-8品种叶长与其余10个品种差异显著，E-3品种叶宽与其余9个品种差异显著；E-7、E-8、E-9杂交狼尾草平均直径超过1．4 cm，其中E-7与其余10个品种差异显著。

For grasping the effects of spring drought on the agronomic traits of hybrid Pennisetum in the shoal saline of northern Jiangsu , and screening out the varieties which were suitable to be planted in beach saline , we studied and tested the agronomic traits ( plant height , tiller number , leaf number , leaf length , leaf width and stem diameter ) of 13 introduced hybrid Pennisetum varieties in beach saline .The results indicated that the plant height of hybrid Pennisetum was suffered seriously from spring drought in beach , E-6, E-9, E-10 and E-11's average plant height was more than 90 cm, and E-9 was significantly different from other 9 vari-eties.The average tiller number of E -11 and E-4 was more than 10 tillers, and had significant difference with that of other 11 va-rieties.The average number of leaf was from 10 to 14, and there was no significant difference among 12 varieties except for E-10. There was significant difference in leaf length between E -8 and other 10 varieties.There was significant difference in leaf width be-tween E-3 and other 9 varieties.The average stem diameter of E -7, E-8 and E-9 exceeded 1.4 cm, and E-7 had significant difference with other 10 varieties.
