为了提高洪泽湖低洼圩区农田的经济效益,1988年我们在洪泽农场低洼圩区进行麦鱼轮作试验,亩产小麦151.5公斤,鱼299.16公斤,亩利润256元。1989年扩大试验,总面积1913亩,亩产小麦199公斤,鱼300.62公斤,亩利润285.7元。其中重点试验区224亩(1988年已进行麦鱼轮作),亩产小麦277公斤,鱼382.9公斤,亩利润479元,比麦、稻轮作亩增利润435.85元,经济效益提高了10.1倍。圩区田块与洪泽湖仅一堤之隔,地面准高11.95,年平均降雨量909.1毫米,其
In order to improve the economic benefits of the farmland in the low-lying polder area of Hongze Lake, in 1988 we conducted a test of wheat rotation in the low-lying polder area of Hongze Farm, yielding 151.5 kilograms of wheat, 299.16 kilograms of fish and 256 yuan of profit per mu. Expand test in 1989, with a total area of 1913 mu, 199 kg of wheat per mu, 300.62 kg of fish, acreage 285.7 yuan. The key trial area is 224 mu (1988 wheat rotation), 277 kilograms of wheat per mu, 382.9 kilograms of fish, 479 yuan of profit per mu, 435.85 yuan more profit of wheat than that of rice and rice and 10.1 times of economic benefit. Polder plots and Hongze Lake only a dike, the ground quasi-high 11.95, the average annual rainfall of 909.1 mm, its
