与西欧大多数国家不同,法国的糖用甜菜主要种植在大农场,因此有可能使用高效而经济的分段收获机具,其中最引人注意的是茎叶收获机,其主要特点是:连续地使用不同的工作部件,将除去茎叶的过程分成2～4道工序来完成。法国埃里奥、莫罗、S·M·C、马特罗等公司的茎叶收获机典型的工作原理示意图如图1。大部分茎叶和杂草是用钢制 Unlike most Western European countries, the French sugar beet is grown mainly on large farms, making it possible to use efficient and economical staging harvesters, of which the most notable is the stem-and-leaf harvester, whose main features are: Using different working parts, the process of removing stems and leaves is divided into 2 to 4 steps to complete. A typical working principle of stem and leaf harvesters in France’s Leo, Moro, SMC, and Matteo companies is shown in Fig.1. Most stems and weeds are made of steel
