| 为探讨开农系列高油酸花生品种最适单粒精播密度，研究以双粒穴播为对照，设置4个不同春播单粒种植密度，对3个高油酸花生品种开农111、开农1715和开农1760的主要农艺性状和产量等指标进行研究。结果显示，随种植密度的降低，3个品种的单株地上部干物质重逐渐增大，而根系干物质重变化不大，不同处理间差异不显著。3个品种的最优种植密度荚果产量均与对照差异极显著，其中，开农111以T2（25.5万穴/hm2）处理最优，产量为5 634.55 kg/hm2，较对照T0增幅达15.04%，开农1760和开农1715均以T3（21万穴/hm2）处理最优，产量分别是5 616.00 kg/hm2和5 375.45 kg/hm2，较对照增幅分别为20.71%和15.80%。 |

| To determine different planting densities for single-seed precision sowing of spring-sown Kainong series high-oleic peanuts, four planting densities were established, with double-seed sowing per hole used as the control, and the main agronomic traits and yield performance of three high-oleic peanut varieties (‘Kainong 111’, ‘Kainong 1715’, and ‘Kainong 1760’) were evaluated. The results showed that, as planting density decreased, the aboveground dry matter per plant of the three varieties gradually increased, whereas root dry matter changed only slightly and did not differ significantly among treatments. For all three varieties, pod yield under different density treatments was significantly higher than that under the control. Specifically, ‘Kainong 111’ performed best under the T2 treatment (255 000 holes/hm2), with a yield of 5 634.55 kg/hm2, representing a 15.04% increase compared with the T0 control. ‘Kainong 1760’ and ‘Kainong 1715’ both performed best under the T3 treatment (210 000 holes/hm2), with yields of 5 616.00 kg/hm2 and 5 375.45 kg/hm2, respectively, which were 20.71% and 15.80% higher than those of the control. These results indicate that a planting density of 255 000 holes/hm2 is suitable for ‘Kainong 111’, whereas 210 000 holes/hm2 is more suitable for ‘Kainong 1715’ and ‘Kainong 1760’ under spring-sown conditions. |
