摘　　要：随着生育期的推进,粗蛋白和粗灰分含量显著下降,而NDF、ADF和可溶性糖含量显著上升;青贮后NDF、ADF含量显著高于青贮前,可溶性糖含量显著低于青贮前(P<0.01),而蛋白质、灰分含量却有所不同,第一茬植株青贮后蛋白质、灰分含量均显著下降,第二茬植株青贮后蛋白质、灰分含量均显著上升。With the maturity postponed, the content of CP and CA decreased significantly and the content of NDF, ADF and WSC increased significantly （p〈0. 05 ） ; The content of NDF and ADF of post-ensiling was more than that of pre-ensiling, and the content of soluble sugar was less than that of pre-ensiling （p〈0.05）. Protein and ash content of the first stubble decreased significantly after ensiling, but that of the second stubble increased significantly.
