小麦—杂交稻配套栽培,2季亩产达到1000公斤以上。我市从1986年开始建设麦杂吨粮田,当年示范面积7.1万亩,1987年发展到28.7万亩,1988年35.2万亩,1989年达45万亩,占麦稻种植面积的50%。从前3年的产量来看,小麦平均单产369公斤,杂交稻685公斤,两季亩产1054公斤,比全市的麦稻2季平均单产增179公斤(其中小麦增49公斤,水稻增130公斤),增20.5%。通过几年的实践,我们摸索出一套栽培技术。一、选用适宜的高产品种(组合) 根据鄂中北 Wheat - hybrid rice cultivation, the second quarter per mu to reach more than 1,000 kg. In 1986, the city started to build grain miscellaneous tons of grain. The demonstration area in that year was 71,000 mu. It developed to 287,000 mu in 1987, 352,000 mu in 1988 and 450,000 mu in 1989, accounting for 50% of the cultivated area of ​​wheat. The past three years of production, the average yield of wheat 369 kilograms, 685 kilograms of hybrid rice, two seasons 1054 kilograms per kilogram, than the city’s average yield of wheat two seasons by 179 kilograms (including 49 kilograms of wheat, rice by 130 kilograms) , Up by 20.5%. After several years of practice, we worked out a set of cultivation techniques. First, the selection of suitable high-yield varieties (combination) according to North Central Hubei
