通过油菜超稀植高产栽培试验分析指出：超稀植油菜增产主要依靠单株的角果数增加，其次是角粒数增加，而千粒重影响很小；油菜超稀植适宜播期可放宽到９月１８日之前，仍可获得高产；油菜的分枝节位与栽培水平直接相关；油菜抽苔初期主茎摘断有超越补偿的功能。 The rapeseed ultra-high-yielding cultivation test analysis shows that: Super-thin rapeseed yield mainly depends on the number of pods per plant increased, followed by the number of grains increased, and 1000-grain weight has little effect; rapeseed planting suitable sowing time can be relaxed to 9 Before the 18th of the month, high yield could still be obtained; the ramifications of rapeseed were directly related to the cultivation level;
