| 摘 要： | 为探讨夏花生单粒播种条件下开花结实规律,探索夏花生生长发育规律及高产机理。以高油酸花生品种‘菏花11号’为材料,采用不同密度单粒播种随机区组试验,田间开花、下针规律连续标记10株,每隔10天调查1次、采用排水法测行荚果体积的数据、采用烘干法测得荚果干物质重量数据。结果表明开花持续时间随密度增加而缩短,果针的形成受开花数的影响,结荚数随密度的增加而降低,产量随密度增加而先增后降。密度为21万株/hm2的秕果数最少,百仁重最高,产量最高。因此,夏花生单粒播种应适当增加密度,密度过高单株开花结实少,密度过低则影响群体产量。

| Abstract: | The aims are to study the flowering and fruiting rule of summer peanut under single-seed sowing, and to explore the growth and development law and high yield mechanism of summer peanut. Using peanut variety ‘Hehua 11’ with high oleic acid as material, the randomized block experiment was designed for single seed sowing with different densities. The regularity of flowering and needling in the field was continuously marked with 10 plants, which were investigated every 10 days. The volume of pods was measured by drainage method, and the dry matter weight of pods was measured by drying method. The duration of flowering decreased with the density increase. The formation of fruit needles was influenced by the blossoms number. The number of pods decreased with the density increase. Pods’ yield increased first then decreased with the density increase. It also showed that at the density of 210000 plants/hm2, the blighted fruits’ number was the least, and the 100 kernels weight and the yield were the highest. The density of summer peanut should be increased appropriately in single seed sowing. High density could result in less flowering and fruiting, while low density could affect the population yield. |
