摘要
采用不同处理方法研究苜蓿干草调制过程中水分散失规律。结果表明:自然晒制苜蓿干草时,苜蓿植株体内水分损失呈现先快后慢的规律,晒制初期前4 h内的水分散失速度最快,含水量下降27.3个百分点;压扁结合喷施干燥助剂处理较其他各处理可明显加快苜蓿的干燥速度,有效减少苜蓿叶片的损失,更好地保存苜蓿干草营养成分的含量,其茎叶比与含水量之间的关系呈指数曲线变化趋势。
In this paper, the influence of different treating methods on the moisture dissipation law were re- searched during then turned slow alfalfa hay making. The results showed that：moisture dissipation tended to be fast at first and during field wilting. The moisture dissipation speed was most rapidly and the moisture content decreased 27.3 percentage during the first 4 hours of sunning;Spraying chemical drying agents combined with steam-pressing could significantly accelerate the drying rate, even could keep nutritive value and improve the quality of alfalfa hay. Thus the loss of leave was reduced efficiently. The correlation of moisture and ratio of stem to leaf submitted index curve variety.
