为了降低烟叶机械采收破损率，推进烟草田间生产机械化采收进程，以中烟100为试验材料，在万能试验机上利用自制的烟叶装夹装置对烟草的茎叶连接强度进行了研究，分析了烟叶成熟度、加载速度对茎叶连接强度的影响。结果表明：未熟期烟叶茎叶连接处界面结合强度较大，属于强界面连接；成熟期烟叶茎叶连接处界面结合强度较未熟期下降约29％，属于弱界面连接，此时机械采收易于降低烟叶破损程度；对成熟烟叶的加载速度越大，所需要的茎叶分离力越小，但速度与力不呈线性关系。

In order to reduce damage efficiency of tobacco mechanical harvesting,to promote the mechanization harvesting process,the connection strength of tobacco stems and leaves for Zhongyan 100 was studied by using the universal testing machine and fixture.The effects of loading rate and maturity of tobacco leaf on connection strength of stems and leaves were analyzed.The results show that connection strength of stems and leaves is big during the immature period,and the interface is strong.The interface connection strength of stems and leaves during the matured period is less than that of the immature period.The value of connection strength during the matured period reduces by 2 9%,and the interface is weak,so it is apt to be harvested by machine and has the lower breakage.When the loading speed to matured tobacco is bigger,the separation force of stems and leaves needed is smaller.The speed and force do not show linear relationship.
