| 摘 要： | 对占全年产草量５０％的第一茬苜蓿进行晾晒楼集试验。结果表明，在当地气候条件下，头茬苜蓿晾晒后应在含水量３２％之前或２３％以上的早晨搂集，其粗蛋白质含量和叶保存率皆高。喷酒碳酸钾（２％，７ｋｇ／ｈｍ＾２）对加速苜蓿干燥有一定作用，碳酸钾对含水量４１．４％以上的苜蓿具有保存粗蛋白质的作用，而含水量在２２．６％以下者则无作用。

| Abstract: | The study on suncuring and raking of the first cutting alfalfa which produced output is50% of annual yield was made. The results are indicated as follows: When alfalfa is raking at any timewith moisture content over 32% or in the morning over 23%,the crude protein (CP) content and leaf preserving rate of alfalfa are high in the local weather condition. The effect of sprayed with 2% potassium carbonate (7kg/ha) field drying of the first cutting of alfalfa is significant. Potassium carbonate conserves CPonly during moisture content over 41. 4 %,but not below 22. 6 % of moisture content. |
