笔者曾于1981年冬至1983年在景德镇市古城公社的古城大队和红源公社的桂花大队蹲点,推广三熟直播油菜宽幅条播丰产栽培技术,取得了显著的增产效果。1982年大面积获得了亩产200多斤的高额丰产典型。1983年春季,正值油菜角果及种子发育时期,虽遭受了连续的大风、暴雨和冰雹的袭击,日照比上年同期减少了52％的大灾年的情况下,但点上4个生产队77户农民,菜籽总产仍比上年增长32％。其中有14亩油菜丰产示范试验田,经市农业局、市科委等有关部门领导及同行专家验收鉴定,种植的甘蓝型早熟品种(黔油04号)亩产120斤,本地甜油菜亩产90～100斤。现将三熟油菜宽幅条播丰产栽培技术总结如下:
The author once worked in the ancient city brigade of the ancient city commune in Jingdezhen City and the sweet-scented osmanthus brigade of the Hongyuan Commune in the winter of 1981 to 1983 to promote the broad-bred broad-field cultivation technology of direct-cooked rapeseed and achieved remarkable yield-increasing effect. In 1982 a large area of 200 kilos per mu yield of high yield typical. In the spring of 1983, at a time when rape cotyledons and seed development were under continuous winds, torrential rains and hail attacks, the sunshine was reduced by 52% from the same period of the previous year but with 4 production points 77 farmers, rapeseed production is still up 32% over the previous year. Among them, there are 14 mu of rapeseed yield demonstration experimental field. According to the inspection and identification of leaders of the relevant departments such as the Municipal Agriculture Bureau, the Municipal Science and Technology Commission and other experts, the cultivated sweet potato variety Muqian 04 ~ 100 pounds. Now three broad rapeseed rapeseed cultivation techniques are summarized as follows:
