(一)建国以来,农田排灌机械有了很大的发展。解放初期,全国排灌机械不到10万马力,并且只集中在江苏等沿海少数几个省份。现在排灌机械已经增加了几十倍,并且遍布全国各省、市、自治区,成为当地抗御旱涝灾害的有力武器。近几年来,我国不少地区遭受了不同程度的旱涝灾害,使农业减产,但是在排灌机械发挥作用的地区,都能够得到适时适量的灌溉或排水,减免了旱涝灾害,增加了农业生产。许多缺粮的县或社、队,自从建设了机械排灌站并且加强管理以后,在灌溉季节,农作物的用水有了保

In recent years, many parts of our country have suffered from varying degrees of droughts and floods, which have resulted in a decrease in agriculture. However, irrigating or draining water can be timely and properly drunk in areas where drainage and irrigation machinery play a role, and drought and flood disasters are reduced and agricultural production increased . Many county-owned counties, social groups and teams have been using water for crop irrigation during the irrigation season since the construction of mechanical irrigation and drainage stations and the strengthening of their management
