:【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. |
