过去一段时间,锦州地区由于过分强调“以粮为纲”,不顾地力条件,强求多种高粱、玉米等高产粮食作物,致使作物种植比例失调,给轮作倒茬造成困难.据调查,平原地区,水肥条件好的社队,玉米重茬为多,如北镇县曹屯公社曹屯大队,1974～1979年6年累计种植玉米5,888亩,重茬面积为1,200亩,占玉米种植面积的21%.水肥条件较差的社队,则以高粱重茬比例大,如锦西县新台门公社砖瓦房大队,1979年1,500亩高粱有900亩是重茬.在花生产区,花生重茬的现象也十分严重.
Over the past period, due to overemphasis on “taking grain as the key link”, Jinzhou Prefecture has forced a large number of high yield grain crops such as sorghum and corn despite the conditions of soil fertility, resulting in the imbalance of crop planting and causing difficulties for crop rotation. According to the survey, plain areas, For example, Cao Tun Brigade of Caotun Commune in Beizhen County, with a total of 5,888 mu of corn planted in the six years from 1974 to 1979, has 1,200 mu of stubble crop, accounting for 21% of the cultivated area of corn. Poor commune teams used a large proportion of sorghum cropping, such as brick and tile house brigade of Xintaimen Community in Jinxi County, and 900 mu of 1,500 mu of sorghum were planted in 1979. In the flower growing area, the phenomenon of stubble in peanuts is also very serious.
