Evaluation on the production performance and feed value of seven grasses in arid areas
[Objective]The planting value of seven grass grasses in the arid areas was investigated to provide theoretical support for the variety selection of grasses planted in this area.[Method]Seven forage crops including Ke-hua 669. Lvbo 6,Sweet Sorghum,Sudan grass,Sorghum sudanense,Pennisetum sinese and Jinmu forage were se-lected as the research objects.Their agronomic traits,hay yield,nutrient content,relative feed value and planting eco-nomic benefits were compared and analyzed under the same water and fertilizer conditions,and the grey correlation de-gree analysis was carried out in combination with various indicators.[Result]The results showed that the hay yields of Kehua 669 and Lvbo 6 hay were 25225.07 kg/hm² and 23692.55 kg/hm²,respectively. The relative feeding value was 170.88 and 147.97,and the economic benefits were 16150.26 yuan and 14203.38 yuan,respectively. The order of grey correlation was Kehua 669＞Lvbo 6＞Pennisetum sinese＞Jinmu Forage＞Sorghum suda-nense＞Sweet Sorghum＞Sudan Grass.[Conclusion]Comprehensive analysis shows that maize varieties of Ke-hua 669 and Lvbo 6 are more suitable for planting in water land in the transition zone of arid and semi-arid areas.
