狼尾草属牧草在金沙江干热河谷区的生产性能及营养价值评价
Evaluation of Productivity and Nutritional Quality of Pennisetum Forages in the Dry-Hot Valley Region of the Jinsha River
摘要
Abstract
To evaluate the growth adaptability of different Pennisetum forage cultivars and lines in the dry-hot valley region of the Jinsha River,eight Pennisetum forage cultivars and lines were assessed in a three-year field experiment.Agronomic traits,production performance,and nutritional quality were compared,structural equation modeling was used to analyze relationships among cultivar,yield,and nutritional quality,and grey relational analysis was used for comprehensive evaluation.The results showed that the mean annual fresh for-age yield of the eight cultivars(lines)ranged from 235.42 to 305.40 t/hm2,with hybrid Pennisetum'Minmu No.6'showing the highest yield and red elephant grass showing the lowest yield.The three-year mean plant height per cutting was highest in'Guiminyin'elephant grass,reaching 223.99 cm,and lowest in red elephant grass,at only 181.06 cm(P<0.05).The crude protein and ether extract contents of'Guiminyin'elephant grass were higher than those of the other cultivars,whereas neutral detergent fiber and acid detergent fiber con-tents were both significantly lowest in'Guimu No.1'.Grey relational analysis indicated that'Guiminyin'elephant grass and'Guimu No.1'hybrid elephant grass were suitable as recommended cultivars for planting in the dry-hot valley region of the Jinsha River.关键词
