摘　　要：以赣花8号为材料,研究了不同用量磷肥(0、45、90、135、180 kg/hm 2,以P 2O 5计,对照为当地习惯施肥)和氮肥(0、60、90、120、150 kg/hm 2,以N计,对照为当地习惯施肥)对南昌地区花生产量的影响。结果表明,氮、磷肥主要是通过影响花生的饱果数、百果重、百仁重等影响产量。在氮肥(N)用量90 kg/hm 2、磷肥(P 2O 5)用量90 kg/hm 2时,花生产量最高,节肥效果最好。与当地习惯施肥相比,该肥料用量水平可使花生产量增加8.97%,磷肥用量减少50%,氮肥用量减少14.3%。Using Ganhua 8 as material,the effects of different phosphorus fertilizer(0,45,90,135,180 kg/hm 2,calculated as P 2O 5,compared with local customary fertilization)and nitrogen fertilizer(0,60,90,120,150 kg/hm 2,calculated in N,compared with local customary fertilization)application on peanut yield in Nanchang were studied.The results showed that nitrogen and phosphorus fertilizer mainly affected the yield by affecting the number of peanuts filled,100-seed weight and 100-kernel weight.When the amount of nitrogen fertilizer(N)was 90 kg/hm 2 and the amount of phosphate fertilizer(P 2O 5)was 90 kg/hm 2,the peanut yield was the highest and the effect of saving fertilizer was the best.Compared with the local customary fertilization,the fertilizer application level could increase peanut yield by 8.97%,reduce phosphorus application by 50%,and nitrogen application by 14.3%.
