摘要
通过田间试验研究了不同加氧处理方式下超级稻产量因素的相关因素分析。加氧处理下超级稻单株产量与常规处理比较有显著性差异,采用SPSS统计软件对不同加氧处理下构成超级稻产量因素的每穗实粒数、稻穗数、千粒重进行相关性分析,得出超级稻单株产量与每株穗数相关系数高。不同加氧处理方式下的白天机械加氧、夜间机械加氧、化学加氧的每株穗数高于不加氧处理分别是17.5%、19.27%、12.8%。不同加氧处理组之间的稻穗数进行多重比较未有显著差异,加氧处理与对照常规处理存在显著差异。加氧处理促进了水稻有效分蘖使稻穗数增加,进而提高水稻产量。
The paper analyzed the impact of different oxygen-adding treatments on the yield of super rice through field experiment. There are significant differences of the yield per plant of super rice between the treatment of adding oxygen and the normal treatment. The paper used SPSS statistical software to analyze the grain number per panicle, spike of rice number and 1000 grain weight under the different treatment of adding oxygen. It got the conclusion that the correlation coefficient between yield per plant and number of spike per plant is high. The different oxygation treatments under mechanical oxygen of daytime and me- chanical oxygen of night and chemical oxygen which spike number per plant is higher than that without oxygen treatment. They are 17.5% , 19.27% and 12.8% respectively. The number of spike of rice be- tween different oxygen treatments by multiple comparison has no significant difference. There are signifi- cant difference between adding - oxygen treatment and normal treatment. The treatment of adding - oxygen have good effective to the increase of tillers of rice panicle number and improve the yield of rice.
