影响花生荚果产量的因素很多，为了探讨花生品种和氮钾因素的最优配比，选择品种、施钾量和施氮量3个因素进行正交试验研究。结果表明：采用合油77-4品种、施用尿素75kg／hm2、氯化钾150kg／hm2的产量最高，纯收益最多，成本收益率也最高。增施氮肥，株高增加，侧枝增长，结果枝数减少，500g果数增加，产量下降；同时成本增加，纯收益减少，成本收益率下降。在施用氯化钾75～225kg/hm2的范围内，施钾量的增产、增收效果不显著。

There are many effects factors of peanut pod yield. In order to investigate the optimal ratio of peanut varieties,N and K application amount,orthogonal experimental was done with varieties and the amount of potassium and nitrogen.The results showed that the group of oil 77 -4 varieties ,75 kg/hm2 nitrogen and 150 kg/hm2 potassium abtainod the highest yield. Net income and cost profit rate was the highest ,respectively. With the increase of nitrogen fertilizer, plant height and side shoot length increased,the number of fruit branch reduced, fruit number of 500 g increased, the production declined. At the same time, cost increased, net income reduced, cost profit rate declined.On the application of potassium chloride 75~225 kg/hm2 range,the increase of yield and income were not significant.
