我县位于辽东半岛中部,无霜期165—185天。为了充分利用我县的热量条件,初步研究了油菜夏播的有关技术问题。经1974年和1975年试种夏播油菜成功后,我县夏播油菜面积逐年扩大。1976年夏播7.5亩,平均亩产127.8斤;1977年全县夏播面积达1万多亩,在秋旱十分严重的情况下,仍获得了亩产60—150斤的较好收成。大芦大队1977年夏播油菜192亩,平均亩产130斤;春播380亩,平均
My county is located in the central Liaodong Peninsula, frost-free period 165-185 days. In order to make full use of the county’s caloric conditions, the preliminary study of the rape summer sowing technical problems. After 1974 and 1975 trials of summer rapeseed success, my county summer sowing area has expanded each year. In the summer of 1976, 7.5 mu of land was muted, yielding an average of 127.8 kilograms per mu. In 1977, the area of summer sowing in the county totaled 10,000 mu. In the very severe autumn drought situation, a good yield of 60-150 kg per mu was still obtained. Da Lu Brigade broadcast summer rape 192 acres in 1977, an average of 130 pounds per mu; spring sowing 380 acres, on average
