采取田间小区试验,研究了不同施肥量、肥料品种、施肥模式对白菜型春油菜品种浩油11号生长及产量的影响。结果表明,不同施肥量、不同肥料品种及施肥模式对油菜籽干物质积累有较大影响,对油菜株高、分枝数、结荚数等也有一定的影响。所有处理中,N、P2O5、K2O、B及有机肥分别为75、151、20、3、450 kg/hm2时产量最高,达2 220 kg/hm2。同时得出,对于旱作、雨养油菜作物在一定气候条件(雨水、光照)、一定施肥量范围内,籽粒干物质积累在与施肥量成正相关。
Field trials were conducted to study the effects of different fertilizers, fertilizer varieties and fertilization modes on the growth and yield of cabbage type spring oilseed rape, Haoyu 11. The results showed that different fertilizers, different fertilizer varieties and fertilization modes had a significant effect on the dry matter accumulation of rapeseed, and had some influence on plant height, number of branches and number of pods. In all treatments, N, P2O5, K2O, B and organic fertilizer had the highest yield of 2 220 kg / hm2 when they were 75,151,20,3,450 kg / hm2, respectively. At the same time, it was concluded that the accumulation of dry matter in grains of dry-rape and rapeseed crops had a positive correlation with the amount of fertilizer applied under certain climatic conditions (rainwater and light) and a certain amount of fertilizer.
