Abstract: Alfalfa is a productive and excellent legume forage extensively planted in North China and successful hay curing technology is important to the alfalfa industry.In this article,the effects of cut period,sunning hours,baling time,and tedding on the second cutting alfalfa hay were studied with three-year-old alfalfa in 2004 in Hexi Corridor area of China in order to determine the appropriate curing technology of alfalfa hay.The results show that the key factors for the successful alfalfa hay curing were sunning hours,tedding time,and baling time;harvesting period and baling time had great effects on alfalfa hay quality.According to the experiment,higher quality and nutritive alfalfa hay with possibility of long time reservation in the Hexi Corridor area was achieved by alfalfa harvesting in initial flowering period,sunning for 2832 hours with tedding,and baling at the time except early morning or evening.The suggested technology will offer a scientific base for alfalfa hay curing and guide the process of alfalfa hay production in North China.

摘要： 紫花苜蓿(Medicago stativaL.)是为建立河西走廊地区苜蓿干草调制技术,于2004年在河西走廊地区以种植3年的紫花苜蓿为材料,对第2茬苜蓿进行了刈割时期、晾晒时间、打捆时间、翻晒对紫花苜蓿干草质量的影响研究.结果表明:苜蓿干草调制成功与否主要决定于晾晒时间、翻晒和打捆时间,而调制的苜蓿干草质量主要决定于刈割时期和打捆时间;河西走廊紫花苜蓿在初花期刈割,晾晒28 h-32 h,并进行翻晒作业,16:00-17:30打捆,避开过早或过晚打捆,可获得质量好、营养价值较高并可长期贮存的干草产品.该技术的提出对我国北方地区调制优质苜蓿干草提供了科学依据.
