摘要
1983年引种成功。通过不同生育期和不同刈割期鲜草营养成分测定,结果认为:串叶松香草苗期营养成分含量最高,但鲜草产量低。进入旺长期至孕蕾前,鲜草产量最高,是作青饲料的最佳利用期;第一次刈割鲜草质量优于第二次刈割。
Sitphium prefoliatum was successfully introduced in 1983.Chemical determination of Silnhium perfoliatum taken in different growth period and several mowing time showed that the contend of nutritive composition was highest in seedling period while green yield low; From vigorous growing period to bud formation stage the green yield reached highest and it is the best time for green fodder use.The quality of green fodder mowed for the first time were superior than that of the secone mowing.
