近年来，割前脱收获工艺，已成为稻麦收获机械研究的主要方向之一。现介绍几种我国自行研制生产的“割前脱”式稻麦联合收割机。4LS天同神农稻麦捋穗联合收割机由石家庄天同神农机械有限公司与中国农机化研究院、河北省农机化研究所联合研制，已投放市场。该机采用梳脱方式，作 In recent years, cutting off before harvesting process, has become the main direction of research on rice and wheat harvesting machinery. Here are some of China’s own research and development production of “cutting off before” rice and wheat combine harvester. 4LS days with the Shennong rice wheat 捋 spike combine harvester by Shijiazhuang TianTong Shennong Machinery Co., Ltd. and China Agricultural Mechanization Research Institute, Hebei Institute of Agricultural Mechanization jointly developed and put on the market. The machine uses comb off way, for
