摘要
采用田间小区试验,研究了不同施肥处理对白菜、甘蓝产量、养分吸收及利用率的影响.结果表明,粪肥、菜饼肥及蔬菜专用肥分别与化肥配施处理的白菜和甘蓝的产量高于纯化肥处理.白菜以蔬菜专用肥与化肥配施处理的产量最高,比纯化肥处理提高了25.30%;对N、P养分的利用率最高的处理分别是菜饼肥与化肥配施处理、蔬菜专用肥与化肥配施处理,白菜产量比纯化肥处理分别提高了21.65%、10.77%;甘蓝以菜饼肥与化肥配施处理的产量较高,比纯化肥处理提高了9.90%,对N和P养分的利用率最高的处理均为菜饼肥与化肥配施处理,甘蓝产量较纯化肥处理分别提高了29.23%、14.9%.
A field plot experiment was conducted to study effect of different fertilization treatments on yield,nutrients uptake and nutrients use efficiency of Chinese cabbage and cabbage.The results showed that:yield of cabbage and Chinese cabbage of the application of manure,oil cake and special fertilizer for vegetables combined with fertilizer is higher than that of the pure chemical fertilizer treatment.The yield of application of special fertilizer for vegetables combined with fertilizer of Chinese cabbage is the highest,yield of it enhanced 25.30% compared with the pure chemical fertilizer treatment;application of oil cake and special fertilizer for vegetables combined with fertilizer are of the highest N and P nutrient use efficiency,N and P nutrient use efficiency of them enhanced 21.65%,10.77% compared with the pure chemical fertilizer treatment,respectively.The yield of application of oil cake combined with fertilizer of cabbage is higher,yield of it enhanced 9.90% compared with the pure chemical fertilizer treatment;application of oil cake combined with fertilizer is of the highest N and P nutrient use efficiency,N and P nutrient use efficiency of it enhanced 29.23% and 14.9% compared with the pure chemical fertilizer treatment,respectively.
