摘　　要：以京丰一号结球甘蓝为试料,在湖北利川海拔1 645 m产区开展"3414"肥效试验,研究不同肥料配比对甘蓝产量的影响。试验结果表明,试验地的基础肥力甘蓝产量为3 790 kg/667 m2,相对产量为66.50%,氮磷钾配合施用能显著提高甘蓝产量,每667 m2的N、P2O5、K2O用量分别15.0,4.8,8.5 kg,单产为5 699 kg/667 m2,缺氮、缺磷、缺钾的相对产量分别为73.73%、92.42%、82.33%;施氮量与产量的曲线关系为y=4 119.7+166.75x-5.195 6x2(R2=0.884 7*),施磷量与产量的曲线关系为y=5 156.6-13.312x+11.936x2(R2=0.411 8),施钾量与产量的曲线关系为y=4 640.9+183.05x-9.010 4x2(R2=0.909 8*);氮磷与产量的曲线关系为YNP=6 344.76-18.46N-537.81P-3.97N2+17.27P2+32.07NP(R2=0.832 4*),氮钾与产量的曲线关系为YNK=4 577.34+64.02N-32.40K-3.64N2-1.80K2+7.41NK(R2=0.983 2*),磷钾与产量的曲线关系为YPK=4 353.66+11.79P+132.42K+12.16P2-4.46K2-3.16PK(R2=0.736 7*);氮磷钾与产量的曲线关系为YNPK=3 815.6+63.8N-113P+234.7K-5N2+7.6P2-5.9K2+19.8NP-0.34NK-20.8PK。Taking Jingfeng No.1 cabbage as test material, we carried out the ＂3414＂ fertilizer efficiency test to study the effects of different fertilizer proportions on the cabbage yield in the producing area with tbe altitude of 1 645 m in Liehuan. The results showed that, while no fertilizer was applied, the cabbage yield was 3 790 kg/667 m^2, and the relative yield was 66.50%. The combined use of nitrogen, phosphorus and potassium fertilizers could significantly increase cabbage yield, and while the application amounts of N, P2O5 and K2O were 15.0, 4.8 and 8.5 kg/667 m^2, the cabbage yield was 5 699 kg/667 ms. The three treatments, lack of nitrogen, phosphorus and potassium fertilizer respectively, possessed the relative yields of 73.73%, 92.42% and 82.33%. The curve equations between nitrogen fertilizer application amount and yield, phosphorus fertilizer application amount and yield, potassium fertilizer application amount and yield were y=4 119.7＋166.75x-5.195 6x^2 （R^2=0.884 7＊）, y=5 156.6-13.312x＋11.936x^2 （R^2=0.411 8） and y=4 640.9＋183.05x-9.010 4x^2 （R^2=0.909 8＊） respectively. The curve equations between both nitrogen and phosphorus fertilizer application amounts and yield, both nitrogen and potassium fertilizer application amounts and yield, both phosphorus and potassium fertilizer application amounts and yield were YNP=6 344.76-18.46N-537.81P-3.97N^2＋17.27P^2＋32.07NP （R^2=0.832 4＊）, YNK=4 577.34＋64.02N-32.40K-3.64N^2- 1.80K^2＋7.41NK （R^2=0.983 2＊）, and YPK=4 353.66＋11.79P＋132.42K＋12.16P^2-4.46K^2-3.16PK （R^2=0.736 7＊） respectively. The curve equation was Y NPK=3 815.6＋63.8N-113P＋234.7K-5N^2＋7.6P^2-5.9K^2＋19.8NP-0.34NK-20.8PK between the application amounts of nitrogen, phosphorus and potassium fertilizers and cabbage yield.
