摘　　要：以珍珠豆商花5号为材料,通过小区试验,设11.25万、15.00万、18.75万、22.50万、26.25万穴/hm^2共5个双粒播种密度和15.00万、18.75万、22.50万、26.25万、30.00万穴/hm^2共5个单粒播种密度,研究种植方式和密度对夏花生性状及产量的影响,以探讨高产田夏花生适宜的种植方式与密度。结果表明,试验条件下,单粒播花生的总分枝、结果枝、单株结果数显著多于双粒播,单株生产力显著高于双粒播;种植方式与密度对籽仁品质影响不显著;单粒播高产种植密度为22.50万~30.00万穴/hm^2,双粒播高产种植密度为18.75万~22.50万穴/hm^2,根据回归方程推算,单双粒播种分别在27.14万、20.68万穴/hm^2密度下,产量最高,分别达5 349.08,5 282.47 kg/hm^2,且单粒播产量高于双粒播,适用于高水肥田。To study the effects of sowing method and density on characters and yield of summer peanut in high fertility soil, a peanut（Shanghua 5）field plot experiment containing five single and double-seed planting density treatments were conducted. Experiment 1was the single-seed（SS）planting containing 5 planting densities（112.5, 150.0, 187.5, 225.0, 262.5 thousand hole/hm^2）. Experiment 2was the double-seed（DS）planting containing 5 planting densities（150.0, 187.5, 225.0, 262.5, 300.0 thousand hole/hm^2）. The results showed that the number of branch and effective branch, the pod number per plant of SS planting peanut was significantly more than those of DS planting peanut. The yield per plant of SS planting peanut was significantly higher than those of DS planting peanut. The effect of planting density and method on kernel quality was not significant. In the density range of 225.0 ^300.0, 187.5 ^225.0 thousand hole/hm^2, the yield of SS and DS planting peanut achieved high level. According to the regression equation, in the condition of 271.4,206.8 thousand hole/hm^2, the yield of SS and DS planting peanut achieved the highest, respectively were 5 349.08, 5 282.47 kg/hm^2. The yield of SS planting peanut was suitable for high fertility soil, which was higher than those of DS planting peanut.
