| 摘 要： | 为了探索合理的花生单粒播模式，采用随机区组设计，研究单粒播种不同株行配比对花生的性状和产量的影响。结果表明：随播种密度增加，花生的单株生产力、单株结果数呈下降趋势；花生饱果率、总分枝数均大于对照。40 cm、33.3 cm行距均在19.5万穴/hm2密度下，荚果产量最佳，但33.3 cm行距下，花生荚果产量与对照不呈极显著差异，分别为6849 kg/hm2、6768 kg/hm2，并且单粒播的产投比明显高于双粒播。综合分析：单粒播种在花生上完全能够实现目标产量，并能取得更好的经济效益。

| Abstract: | In order to explore reasonable single-seed sowing mode in peanut, the experiment adopted randomized block design and study the effects of different row spacing on characteristic and yield in peanut single-seed sowing. The results showed that, yield and pod number of per plant showed a decreasing trend, with the increasing of sown density. Both of full pod rate and the total number of branches were greater than CK. In the condition of 195000 caves /hm2 density, pod yield of 40 cm and 33.3 cm row spacing reached the highest. But in the condition of 33.3 cm row spacing, the difference of peanut pod and CK yield was significant at the level of 1 percent, respectively were 6849 kg/hm2, 6768 kg/hm2. The input-output ratio of single-seed sowing was significantly higher than double-seed sowing. The survey analysis showed that, in summary, single-seed sowing was able to achieve the target yield and to achieve better economic benefits in peanut. |
