摘要
大白菜因其分布广、产量高、种植面积大在人们的菜篮子中占有重要的地位。通过10个施肥处理的随机重复试验得出:处理8(N360P90K270)的产量最高;不同处理下,晋菜3号大白菜吸氮量的变化规律基本一致,团棵期到结球初期(播种后25～45d)吸氮量最多;10个处理的大白菜球叶硝酸盐含量均比外叶低。
Cabbage is of importance to people＇s life due to its wide distribution, high yield and large area cultivation. The re- suits of 10 fertilization treatments of random replicates showed that treatment 8 of N360P90K270 had the highest yield; the change law of Jincai 3＇s nitrogen absorption was similar having the highest nitrogen absorpsion in initial period growing into ball from the 25th to 45th day after sowing; and nitrate accumulation in hall leaf is lower than that in outer leaves in all ten treatments.
