为了探索南方丘陵地区水稻生产机械化的途径,我们与湖北省农业机械化研究所合作,从1980年开始进行《水稻生产过程机械化经济效果的分析》这一课题的研究。研究的目的,是在当前选择性机械化的条件下,根据不同地区的水稻耕作制,选择经济效果最优的机械化项目与机型,确定合理可行的机、畜、劳综合配备系统。一九八○至一九八一年第一阶段研究任务是:以双季稻为主体,以无土肥水育秧中苗机插和收割以 In order to explore ways of mechanization of rice production in the hilly areas in the south, we cooperated with Hubei Provincial Institute of Agricultural Mechanization to start the research on the topic of “Analysis of Economic Effect of Mechanization of Rice Production Process” from 1980 onwards. The purpose of this study is to select the mechanized projects and models with the best economic effect according to the rice farming system in different regions under the current selective mechanization conditions and determine a reasonable and feasible integrated system of machinery, livestock and labor. The first phase from 1980 to 1981 research tasks are: double cropping rice as the main body to fertilize soilless seedling machine seedling machine and harvesting
