不同刈割时期对紫花苜蓿和红豆草产量及营养价值的影响
Effect of Mowing Period on the Yield and Nutrition Level of Alfalfa and Sainfoin
摘要
Abstract
Different grass mowed at vegetation stage,budding stage,early blooming stage,full blooming stage and seed bearing stage were chosen to investigate the effect of growth period and variety on the yield and nutrition level of alfalfa and sainfoin.The results showed that fresh yield and hay yield of Xinmu No.2 were significantly higher than that of the other uarieties(P＜0.05).In vegetation stage,the content of crude protein (CP),Ash and Ca were significantly higher than that of the other stage.In full blooming stage,the content of neutral detergent fiber (NDF) of grass are higher than the other stage (P＜0.05).The content of neutral detergent fiber (NDF) and acid detergent fiber (ADF) increased,respectively (P＜ 0.05),and RFV decreased,respectively (P＜0.05).The content of DM,CP,EE,CF,Ash,Ca,NDF,ADL,AIA and RFV of five varieties were not significantly different (P＞0.05).In bud stage,the yield and nutrition level of grass was better than the other stages.The yield and nutrition level of Xinmu No.2 was better than the other varieties.关键词
