日前,我国首台稻田开沟机由中国水稻研究所稻作技术研究中心与浙江理工大学、水稻产业体系栽培与土肥研究室和设施与设备研究室联合研发成功。据专家介绍,该机具有携带方便、操作简易等特点,每小时可完成稻田开沟0.67hm2(10亩)。近年来,我国水稻生产受劳动力紧张及劳动成本高的影响,水稻田丰产沟的开挖工作难以实施,造成水稻成穗率不高,时常发生倒伏减产。稻田开沟机的研发成功,不但降低了农民劳动强 Recently, the first rice trencher in China was successfully developed by the Rice Research Center of Rice Research Institute of China and Zhejiang University of Science and Technology, the cultivation of rice industry system, the research center of soil and fertilizer and the facilities and equipment. According to experts, this machine has the characteristics of easy carrying, easy operation and so on, completing 0.67hm2 (10 mu) of paddy field ditching every hour. In recent years, the rice production in our country is affected by labor shortage and high labor costs. It is difficult to implement the excavation work of paddy tundra production ditch, resulting in the low spike rate of rice and frequent lodging and yield reduction. The successful development of the rice ditching machine not only reduces the labor intensity of farmers
