该机(图1)是在上海群众性行间中耕机研制的基础上发展的。自一九七五年开始,经四次改进,通过五百多亩的性能试验及生产考核,并经今年台机三百八十多亩的生产使用,表明机具工作质量基本上满足上海地区农艺要求。该机使稻的秧根周围都能中耕,并能使稻秧抖动、松散,耕后土质疏松、泥浮,便于水稻发棵。机具伤苗率少,补棵少,在操作熟练情况 The machine (Figure 1) was developed on the basis of research and development of cultivators in Shanghai’s mass lines. Since 1975, after four improvements, the project has passed the performance test and production test of 500 mu and has been used for production of over 380 mu of Taiwanese machines this year. This shows that the quality of the work performed by the machine basically meets the needs of the agro-industry in Shanghai Claim. The machine so that the rice seedlings can cultivate around, and can make the rice seedlings shaking, loose, loose soil after cultivation, floating mud, easy to paddy rice. Machine injury injury rate of less, make up fewer trees, proficiency in the operation
