摘　　要：研究收获期对新美甜816、粤甜27和华甜5号三种甜玉米秸秆主要营养成分的影响,挑选出最适合青储的甜玉米品种.采用饲料常规分析法,动态分析授粉后4个收获期甜玉米秸秆中粗蛋白、粗脂肪和纤维含量变化.授粉后第22 d,甜玉米秸秆主要营养成分均符合动物采食秸秆的最低标准;甜玉米秸秆适宜收获时期在授粉后第22 d,新美甜816的秸秆更适合做青储饲料.To study the impact of the harvest period on the main nutrients of Xinmeitian 816,Yuetian 27 and Huatian 5 straw and select the sweet corn varieties suitable for silage.The conventional feed analysis method was used to dynamically analyze the changes of crude protein,crude fat and fiber content in the stalks of four sweet corn varieties after pollination.On the 22 nd day after pollination,the main nutrients in the sweet corn stalks were in line with the minimum standards for animal feeding straw.The suitable harvest time of sweet corn stalks is on the 22 nd day of pollination.The straw of Xinmeitian 816 is more suitable for silage.
