| 摘 要： | 为了确定适宜河北低平原区油葵高产高效机械化生产的株行距配置,以当前生产中种植面积较大的中早熟品种新葵20和晚熟品种SD567为试验材料,在适宜机械化和轻简化栽培的宽窄行（70cm+50cm）种植的前提条件下,设置24、26、28、30、32、35cm等6个株距,研究不同品种不同株距配置条件下油葵的生长发育特点及产量。结果表明：不同品种在同一株距配置条件下油葵各生育阶段的干物质积累量、单株叶面积及产量多数处理间差异不显著,但同一品种在不同株距配置条件下油葵各生育阶段的干物质积累量、单株叶面积及产量都是以宽窄行（70cm+50cm）、株距30cm的处理为最高。说明油葵在宽窄行（70cm+50cm）、株距30cm的行株距配置条件下,水肥效应和光合效应得到了最大发挥,能够获得最大产量,适宜于河北低平原区当前的油葵生产。

| Abstract: | In order to determine suitable plant spacing allocation for high yield and high efficiency mechanical production of oil sunflower in low plain area of Hebei Province. Two widely planted varieties, Xinkui 20 and SD567, were planted to develop under wide-narrow row (70cm+50cm), which was suitable for mechanized and simplified cultivation, with plant spaces of 24cm, 26cm, 28cm, 30cm, 32cm and 35cm, respectively. The results showed that the plant space of 30cm produced the highest dry matter accumulation, leaf area per plant and yield. Under the cultivation of wide-narrow row (70cm+50cm) and plant space of 30cm, the water, fertilizer and light can be maximized to utilize and the maximum yield can be obtained, which is suitable for the current production of oil sunflower in the low plain area of Hebei Province. |
