Using two peanut varieties Shanhua108 (early-maturing variety) and 780-15 (late maturing variety), a field experiment was conducted to investigate the influences of row-spacing of wheat (25 cm, 30 cm, 40 cm+20 cm) and two peanut cropping patterns (intercropped peanut with wheat, summer-sowing peanut) on yield components, photosynthetic characteristics, antioxidant system, and dry matter accumulation and transportation. The results showed that wide spacing form of wheat and wide-narrow row planting pattern increased the pod yield, kernel yield, leaf area index, total dry matter accumulation and photosynthetic capacity, as well as SOD, POD and CAT activities, but decreased the MDA content. There are no obvious differences of wheat yield between the two row-spacing. Intercropping system increased peanut yield compared with summer-sowing peanut, which were much higher for wide-narrow row planting pattern than row spacing of 25 cm or 30 cm. The wide-narrow row planting pattern increased the pod yield and kernel yield by 6.3%, 13.3% and 7.7%, 16.5% for Shanhua108 and 780-15 than those of row spacing of 30 cm, respectively. Wide-narrow row planting could enlarge photosynthetic area, improve the net photosynthetic rate, and increase total dry matter accumulation. Meanwhile, it could alleviate the contradictionbetween the plant individual and group, delay the senescence, and increase peanut yield.
以山花108（早熟品种）和780-15（晚熟品种）两个花生品种为材料，进行田间试验，研究小麦行距（25厘米、30厘米、40厘米+20厘米）和两种花生种植模式（小麦间作花生、夏播花生）对花生产量构成因素、光合特性、抗氧化系统以及干物质积累与转运的影响。结果表明，小麦宽行距和宽窄行种植模式提高了荚果产量、籽仁产量、叶面积指数、总干物质积累量和光合能力，以及超氧化物歧化酶（SOD）、过氧化物酶（POD）和过氧化氢酶（CAT）活性，但降低了丙二醛（MDA）含量。两种行距下小麦产量无明显差异。与夏播花生相比，间作系统提高了花生产量，宽窄行种植模式的增产效果远高于25厘米或30厘米行距。与30厘米行距相比，宽窄行种植模式使山花108和780-15的荚果产量分别提高了6.3%、7.7%，籽仁产量分别提高了13.3%、16.5%。宽窄行种植能扩大光合面积，提高净光合速率，增加总干物质积累。同时，能缓解植株个体与群体之间的矛盾，延缓衰老，提高花生产量。
