Abstract:
      :【Objective】 The study tried to have a comprehensive understanding of the forage germplasm resources suitable for local cultivation and to optimize the promotion strategy of forage species. 【Method】Through field-planting trial, the yield and nutritional components of 7 main forage grass cultivars were compared. 【Result】 The P.purpureum×P. typhoideum cv Reyan No.4 had highest grass yield, with a yield of up to 329.67 kg each plot, which was significantly different compared with other cultivars. And the P. purpureum had lowest plant height and yield. The contents of crude protein was higher in P. purpureum Schumach and P.purpureum Schumab cv. Purple compared with that of others(6%- 7%), with the contents of 8.01% and 7.83%, respectively. The content of crude fiber of P.purpureum cv.Guimu No.1 was 33.68%, and those of others were 29%-32%. 【Conclusion】 Combined with the analysis res1ults of the production and nutritional components, it is suggested that the local promotion and utilization order for the main forage grass cultivars of Pennisetum is: P.purpureum×P. typhoideum cv.Reyan No.4, P.purpureum Schum.cv.Guiminyin, P. purpureum Schumach, (P.americanum×P.purpureum)×P. purpureum cv.Guimu No.1, P.purpureum cv.Huanan, P.purpureum Schumab cv.Purple, P. purpureum. In practical production, different varieties can be planted according to different needs.
