摘　　要：通过花生连作风沙土微区定位试验研究了施用化肥、有机肥以及化肥与有机肥配合施用对连作花生的植株性状、产量及其产量构成因素和品质的影响。结果表明:有机肥与化肥配施可以增加连作花生主茎高度和第一侧枝长度,提高花生籽仁的产量、粗蛋白和粗脂肪含量,但对单株分枝数影响不大。增施P、K肥均能提高单株荚果数和出仁率,增施P肥对提高粗脂肪含量也有积极作用。而单施N肥易造成植株徒长,出仁率降低。有机肥和化肥配合施用平均比单施化肥和单施有机肥分别增产15.36%和13.83%;有机肥和氮磷或氮磷钾配合粗蛋白含量平均比单施化肥和单施有机肥分别提高4.94%和4.47%,粗脂肪平均也分别提高了7.62%和5.68%。The effects of chemical fertilizer and munure on the plant trait,yield and its forming factors and quality of peanut were studied by continuous cropping in aeolian soil location micro-plot experiment.The results showed that munure and chemical fertilizer inoculated could increase main stem height,lateral branch length,and improve the yield and quality,including increasing the contents of protein and fat,and having little effect on the branch number.Increasing P,K fertilizer all could improve pods.P fertilizer could enhance fat.but N fertilizer caused plant moderate growth and make pods reduced.The average yield of appling manure with fertilizers was increased 5.36% and 13.83% by single manure or fertilizers respectively.The average content of crude protein in treatments from appling munure with fertilizers was added 4.94 and 4.47 percentage compared with treatments of only munure or fertilizers,respectively.The average crude fat was increased 7.62 and 5.68 percentage compared with single manure or fertilzers,respectively.
