摘　　要：利用"3414"田间肥效试验,研究N、P、K肥对大白菜晋菜1号产量、经济效益的影响,并分析了肥料利用率。结果表明,合理施用N、P、K肥能产生显著的增产增收作用,试验表明:合理配施N、P、K肥,大白菜晋菜1号增产量最高达6 417 kg/hm2,增加的纯收入为18 148.5元/hm2。在生产中不能盲目加大肥料用量,要根据土壤肥力状况及大白菜对养分的需求规律,做到N、P、K肥合理配施,以减少肥料损失,同时加强土壤培肥至关重要。"3414" field fertilizer test was conducted to study the effects of N,P and K fertilizer on yield and economical efficiency of Chinese cabbage Jincai No.1 as well as the fertilizer use efficiency.The results showed that reasonable utilization of N,P and K fertilizer could increase the yield obviously.The yield of Chinese cabbage Jincai No.1 could be increased by as high as 6 417 kg/hm2 by reasonable utilization of N,P and K fertilizer,while the increase of pure income was 18 148.5 yuan/hm2.The dose of fertilizer in practice should not be increased blindly but applied according to soil fertility and need of Chinese cabbage so that the formulation of N,P and K fertilizer was reasonable and loss of fertilizer could be reduced.Meanwhile,enhancement of soil fertilization was essential.
