摘　　要：以珍珠豆小果型花生远杂6号为材料,研究了夏直播花生在1.8×10^(5)~2.25×10^(5)穴/hm^(2)密度及不同配置方式下叶片功能、光合特性及产量等指标的变化,探讨了合理密植对花生群体生殖生长及产量的影响。结果表明:与1.8×10^(5)穴/hm^(2)密度相比,2.25×10^(5)穴/hm^(2)种植会降低叶片净光合速率、抗氧化能力和群体间中下部光合有效辐射截获率,提高群体叶绿素含量、叶面积指数和上部光合有效辐射截获率,提高饱果率和出仁率。2.25×10^(5)穴/hm^(2)产量比1.8×10^(5)穴/hm^(2)处理产量高12.44%,双粒播种产量比单粒播种高12.47%,等行距种植和宽窄行种植产量基本一致。远杂6号为耐密品种,夏直播种植,适当增加种植密度,可有效提高产量,改善荚果商品性。To explore the the effects of proper planting density on the reproductive growth and yields of peanut population,Yuanza 6,Spanish type peanut with small pod was used as the material,the changes of leaf function,photosynthetic characteristics and yields of peanuts under various combinations in summer-planting peanut were studied.The results showed that the planting model of 2.25×10^(5) hole/hm^(2) could reduce the net photosynthetic rate,antioxidant capacity and the photosynthetic effective radiation interception rate of the middle and lower part of the population,and increase the chlorophyll content,leaf area index and the photosynthetic effective radiation interception rate of the upper part of the population,and increase the full pod rate and kernel rate compared with that in1.8×10^(5) hole/hm^(2).Yields of the planting model of 2.25×10^(5) hole/hm^(2) was 12.44%higher than that in 1.8×10^(5) hole/hm^(2),yields of double seed was 12.47%higher than that of single seed,and yields of equal row spacing planting and wide-narrow row planting were basically the same.Yuanza 6 is a close-planting variety,which can be planted directly in summer.The planting density of the variety is increased properly,yields can be increased effectively and the commercial quality of pods can be improved.
