摘　　要：采用随机区组设计,研究5个不同播期对夏花生商花5号发育、干物质积累以及产量的影响。结果表明:随播期推迟,生育期、出苗天数缩短,地下部干物质积累减少,后期地上部干物质消耗加大;花生各主要性状均随播期推迟逐渐减少,6月5日、6月10日、6月15日播种的花生产量处于较高水平,分别为6 027.81、5 558.36、5 027.80 kg/hm^2,处理间呈极显著差异,6月20日、6月25日播种的花生产量为3 994.46、3 838.91kg/hm^2,仍有一定的经济产量。因此,商花5号是耐晚播品种,适宜播期为6月5日—15日。The effects of 5 sowing dates on development,dry matter accumulation and yield of summer peanut variety Shanghua 5 were studied by random block design. The results showed that with the delay of sowing date,the growth period and emergence days were shortened,the underground dry matter accumulation decreased,the aboveground dry matter consumption increased at the later period,and the main traits of peanut gradually decreased. When the sowing date was on June 5,June 10 and June 15,the peanut yield was 6 027.81,5 558. 36 and 5 027. 80 kg/hm^2 respectively,and all reached to a higher level with very significant difference. When the sowing date was on June 20 and June 25,the peanut yield was 3 994. 46 and 3 838. 91kg/hm^2 respectively,which still had some economic yield. Therefore,Shanghua 5 was a late sowing variety,and its optimum sowing date was from June 5 to June 15.
