1引言我国甜菜生产机械化落后,特别是收获环节的机械化作业水平低更是不争的事实。如何利用国产机械装备来推进我国甜菜收获机械化发展,是摆在农机人面前的一个重要课题。但是发展什么样的机型来满足实现我国甜菜生产机械化的要求,目前尚没有统一的认识,仍处 1 Introduction China’s sugar beet production mechanization backward, especially in the harvest part of the low level of mechanization is an indisputable fact. How to make use of domestic machinery and equipment to promote the development of mechanization of sugar beet harvest in China is an important issue before the agricultural machinery. However, what kind of models to develop to meet the requirements of mechanization of sugar beet production in our country, there is no unified understanding, still
