北方地区稻田养鱼与南方相比,有耕作、季节、温度等差别。为了探索本地区稻田养鱼的高产途径,1990年在我区马头镇桥东村进行“麦茬稻田养鱼短期高产试验”,面积11亩,经过3个月的试验管理,共收获稻谷3971公斤;田间鱼苗经70天饲养,捕捞大规格鱼种750公斤。亩均产稻谷361公斤,比不养鱼稻田增产50.8公斤;亩均产鱼68.2公斤。共计新增收入5810.2元,亩新增收入528.2元,是不养鱼稻田亩产值310.2元的1.7倍。在这11亩稻田中,有0.77
Compared with the south, there is a difference in cultivation, season, temperature and so on in the rice fields in northern China. In order to explore the high-yielding ways of fish farming in paddy fields in the region, in 1990, we conducted “short-term high-yielding trial of fish farming in stubble paddy field” in Qiaodong Village, Ma Tau Town in our district with an area of 11 mu. After 3 months of trial management, a total of 3,971 kilograms of paddy In the field, the fry were raised for 70 days and caught 750 kg of large-sized species. Mu is 361 kilograms of rice, 50.8 kilograms more than that of non-fish farming; and 68.2 kilos of mus are produced. Total new income of 5810.2 yuan, 528.2 yuan new acres of income, is not raising rice paddy yield 310.2 yuan 1.7 times. In this 11 acres of rice fields, there are 0.77
