摘　　要：研究了平衡施肥对湖北省主产区花生产量和经济效益的影响。结果表明,与不施肥相比,不同试验区平衡施肥后花生产量均增加;平衡施肥能达到较高的产投比;平衡施肥每公顷收入增加,但不同地区差异较大,部分增产幅度较低的地区出现增产不增收现象。表明此时土壤养分并不是主要的限制因子,生产上应注意提高平衡施肥的经济效益。The effects of balanced fertilization on peanut yield and economic benefits were studied in peanut main production area of Hubei province. The results indicate that compared with no fertilization, balanced fertilization could improve the yields of peanut in all experiment site. The average ratio of output to input was higher after balanced fertilization. The average net income increase per hectare, but there had big differences in different experiment sites, and some experiment sites had phenomenon of yield increase but income decrease.
