中粳晚栽是近年来水稻栽培上的一项改革。在目前复种面积不断扩大的情况下,中粳晚栽对于解决用地与养地的矛盾和作物合理布局起到了积极的作用,促进了水稻单产的提高。1972年全县中粳晚栽面积约7万亩,占水稻面积的15％,亩产一般在700斤左右,高于水稻平均产量。铜山公社墩塘大队晚栽中粳350亩,亩产650斤。新城公社新华大队周庄生产队晚栽中粳21.5亩,亩产934.8斤。 Late japonica rice planting is a reform in rice cultivation in recent years. Under the circumstances that the area of ​​multiple cropping is expanding at present, the late planting of late japonica rice played a positive role in solving the contradiction between land use and raising land and the rational layout of crops, and promoted the improvement of rice yield. In 1972, the area of ​​late japonica rice planting area was about 70,000 mu, accounting for 15% of the rice area. The average yield per mu was about 700 kg, higher than the average output of rice. Tongshan commune Pier Tong brunches planted in the late 350 acres of rice, 650 kg per mu. Metro Xinhua Brigade Zhouzhuang production team planted late Japonica 21.5 acres, 934.8 kg per mu.
