落河田是由于长期水土流失,泥沙淤积,使河床抬高而形成的一种低产田。这种田的田面比河床低,渍水冷浸,土壤质地较轻,养分缺乏,产量低而不稳。群众说落河田是:四月插青苗,五月“穿红袍”,拼命下肥料,还是等外苗;天旱收一半,天雨全淹光。蕲春县1962年时有落河田8万亩,占水田面积的8%。经过二十年的治理,全县的落河田都得到不同程度的改良,其中5万亩治理得比较彻底,逐渐变成高产稳产农田。据狮子、刘河和张榜三个公社七个大队的调查,5,450亩落河田双季稻亩产由改良前的400—500斤上升到1,026斤,而且种上了冬 Ladahe is a low-yielding field formed due to long-term soil erosion, sedimentation and elevation of the riverbed. The field of this field is lower than the riverbed, waterlogging, soil texture lighter, lack of nutrients, low yield and instability. The masses said Hetiantian is: inserted in April young, May “wearing red robe”, desperately under the fertilizer, or other seedlings; half the drought, all the rain submerged. Qichun County, 1962, there are 80,000 mu of Wada Hetian, accounting for 8% of paddy field area. After two decades of governance, the whole county has been improved in varying degrees in the Hetianhetian area, of which 50,000 mu have been more thoroughly managed and gradually become high-yield and stable farmland. According to the survey conducted by the seven brigades of Lions, Liuhe and Zhang Bang, the 4,450 mu of Riehetian double cropping paddy yield increased from 400-500 jin before improvement to 1,026 jin and planted winter
