我场三星大队第五作业队的干部、群众,在先进经验的启发下,革新大白菜种植方法,改移栽为直播取得了较好的效果。一九七六年试种14亩直播大白菜,平均每亩80担,(光菜下同),比相同条件下移栽的田块增产12.3％,一九七七年扩大试种,直播31亩,平均亩产86.4担,比移栽的增加44％,其中8月15日直播的3亩地,亩产103.45担。直播大白菜为什么比移栽的有较大的增产潜力?我们进行了定点,定期观察,考种,座谈总结,其原因主要是:(1)直播大白菜根系发达。在莲座期挖根观察,直播的主根深达1.2尺,而移栽的只有6寸,到收获期挖 My field Samsung working team of the fifth team of cadres and the masses, inspired by advanced experience, innovate cabbage cultivation methods, change the transplanting for the direct broadcast achieved good results. In 1976, 14 mu of live cabbage was planted, with an average of 80 taels per acre (same light dish), 12.3% more than the plots transplanted under the same conditions. In 1976, the trial planting and direct broadcast 31 Mu, an average of 86.4 mu per mu, an increase of 44% over the transplanted ones, of which 3 mu are directly sowed on August 15, with a yield of 103.45 mu. Why Chinese cabbage broadcast transplanting greater yield potential? We conducted a fixed point, regular observation, test species, discussion summary, the main reasons are: (1) live broadcast root cabbage developed. Digging root observation in the rosette period, the main root broadcast live depth of 1.2 feet, while transplanting only 6 inches, to harvest the dig
