前两年春油菜的高产栽培试验,尽管缺乏必要的仪器设备进行分析测定,但仍积累了一些春油菜高产栽培的实践经验。这些经验的进一步验证是今年油菜高产栽培试验的主要任务。由于没有比上更为理想的土地条件。所以,本试验实际上还有推广性的试验性质因此,本试验在土地和品种的选择、肥料的配合比例方面与上年有所不同。试验结果:1.24亩7819油菜,总产902.3斤,平均亩产727.66斤。产量比1978年在同一地块上种植的青油四号(亩产660.7斤)有所提高。

Therefore, the experiment actually has the nature of promotion test. Therefore, the experiment is different from the previous year in terms of the choice of land and variety and the proportion of fertilizer.
