近几年,我省油菜种植面积虽有较大发展,但单产较低、栽培技术落后,因此在新品种选育后,很有必要研究怎样配合相应的栽培技术,摸索出早熟甘蓝型油菜,在直播栽培情况下,掌握比较合理的施肥量、施肥法和密度等,为今后大面积油菜生产提供理论依据。我所于一九七九至一九八○年度进行了此项试验。
In recent years, although our province rapeseed area has a greater development, but yields are low, cultivation techniques behind, so after the breeding of new varieties, it is necessary to study how to cooperate with the corresponding cultivation techniques to explore the early rapeseed rape, In the case of direct seeding cultivation, to grasp more reasonable amount of fertilizer, fertilization and density, etc., provide a theoretical basis for the future large-area rapeseed production. I conducted this test in 1979-1980.
