摘要
紫花苜蓿作为牧草之王,是草食畜牧业中重要的优质豆科牧草,收获制度对紫花苜蓿生产性能有重要的影响。本文重点从刈割时间、刈割频率和留茬高度等三个方面阐述了其对紫花苜蓿生产性能的影响。综合研究结果,紫花苜蓿的最佳刈割期是初花期,刈割频率一年4-6次、留茬高度5-10cm较为适宜。
Alfalfa is known for ＂ the king of forage＂,it＇s an important an d high nutritional vaanimal husbandry,and the harvest system has important influence on the production performance of alfalfa. The paper discus-ses the effects of harvest system on the production performance of alfalfa from three respects of harvest tiand stubble height separately. Comprehensive research result shows that the best cutting time is the first flowering period,theoptimum times of cutting is 4 - 6 times in a year,and 5 - 10cm is suitable for the stubble height.
