早稻翻秋栽培,即用早季收获的种子在当年晚季种植,这对缩短育种年限,加速良种繁育,扩大晚季品种资源或弥补早季受灾损失等,都有重大的意义。 1963年我区遭受了特大的旱灾,为了弥补早稻的损失,解决扩大晚稻所需的种子问题,特别是为使受灾地区1964年有适合当地的早稻种子,许多地方大面积进行了翻秋栽培。此外,还有的地方为了迅速推广良种,也进行了翻秋栽培。早季的稻种作晚季栽培,栽培的环境条

In order to make up for the loss of early rice and to solve the problem of seeds needed for expanding late rice, especially in early spring in 1964, there were large areas for autumn cultivation in many areas.
