| 摘 要： | 研究刈割时期和调制方法对二年生草木樨干草产量和质量的影响。结果表明，初期头茬刈割可获得较高的鲜干草产量及最高及最高粗蛋白南总产量。现蕾至初花期刈割，干划的营养成分含量最高。在直接晾晒、喷碳酸钾（２．５％）晾１压扁茎杆景和压扁茎杆后喷碳酸钾（２．５％）四种调制方法中，后三种方法都能加速干燥，减少营养物质损失，其中以喷碳酸钾（２．５％）的晾晒方法快速简便，值得推荐。

| Abstract: | Studies were conducted at Yuershan Farm,Chengde Distribt of Hebei province on sweetclover pasture to determine the optimal cutting time and drying method. The first cutting at early bloomcan be obtained higher yield (10285. 5kg/ha)and the highest crude protein yield (1859. 42kg/ha)of two total cuttings. The highest nutritive values of sweetclover is during the period from prebloom to early bloom.Spraying of K2CO3,pressed stems and branches and spraying K2CO3 after pressed stems and branches couldaccelerate the drying rate,decrease the losts of nutrition in four treatments for drying. The spraying K2CO3,could fasten the drying speed and it is simply to be done,so it should be recommended to use in sweetcloverhay production. |
