以紫花苜蓿为研究对象,通过第二茬和第三茬收割的鲜草在田间的晾晒、观测记录,探讨水分随晾晒时间的变化规律及其下降至54％左右所需要的时间.结果表明,第二茬紫花苜蓿在上午收割的鲜草晒6 h,含水量从79.38％降至53.72％,下午收割的则在18 h后降至54.28％;第三茬在上午收割的鲜草晾晒8 h,降至53.60％.

Taking alfalfa as the research object , the change regular of moisture with the drying time and the time about the moisture down to around 54% were discussed , through the drying and observation records of the second and third crops harvested grass in the field.The results showed that , the second crop of alfalfa dried 6 h while the harvest in the morning , the moisture down to 53.72% from 79.38%, while the harvest in the afternoon , the moisture dropped to 54.28% after 18 h.The third crop of alfalfa dried 8 h while the harvest in the morning, the moisture dropped to 53.60%.
