1985年9月,在安徽巢湖召开的全国杂交中稻会议上,襄樊市接受了农牧渔业部农技推广总站下达的麦杂(小麦—杂交中稻,下同)连作两熟亩产吨粮课题。开发吨粮田工作自1986年开始试验研究推广以来,连续四年获得了成功。1986年全市有55个乡(镇)583个村3750个组131205个农户参加了吨粮攻关活动,48.85万亩麦杂两熟亩产达到1034.5公斤,占粮食复播面积的3.8％,亩产值393.11元,比同等条件下常规栽培方式的麦杂田亩增产90.1公斤,增值34.24元。1987年扩大到87.75万亩,亩产1025.82公斤,亩产值543.68元,比一般麦杂连作田亩增产
In September 1985, at the national hybrid mid-rice conference held in Chaohu, Anhui Province, Xiangfan City received the two-acre per-mu production of grain crops from the hybrid rice (wheat-hybrid middle rice, the same below) issued by the Agricultural Technology Extension Station of the Ministry of Agriculture, Animal Husbandry and Fisheries. The development of the Triticum Field has been successful for four years in a row since its pilot study was launched in 1986. In 1986, there were 131,205 farmer households in 3750 groups in 583 villages of 55 townships (towns) participated in the ton-grain research project. 488,500 mu of wheat and double-cropping per mu reached 1,034.5 kilograms, accounting for 3.8% of the grain sown area. The output per mu 393.11 yuan, 90.1 kilograms more than the equivalent cultivation methods under the same conditions of miscellaneous acres of wheat acres, added value of 34.24 yuan. 1987 expanded to 877500 acres, 1025.82 kilograms per mu, mu production value of 543.68 yuan, compared with the general malt even cropland mu increase
