论高产棉花的同步栽培——Ⅰ.棉花高能期与高能季节同步的增产效应

摘  要:
提要长江下游棉区,常年7月中旬—8月底为日照最充足的高能季节,棉花一生中转化贮存光能最多的高能期(集中结铃阶段)与此同步,具有极为明显的增产效应。 1968—1983年的研究结果表明,棉花产量与同步期光能呈极显著正相关(r=O.8779),其回归方程为:y=181.03+23.56x。

On the Synchrocultivation of High Yield Cotton I. The Yield-increasing Effect of Synchronism between Actively Energv-conserving Period and High Energy Season on Cotton

摘  要:
In the region around the lower reach of Yangtze River, the highest energy season, namely the season with richest sun radiance usually from mid-July till end of August, is synchronous with the period when cotton fixes and conserves light energy most actively and sets most of its bolls. This kind of synchronism has a significant effect on the increase of cotton yield. According to research data obtained during 1968—1983, the cotton yields showed a significantly positive correlation with the sychronous high energy season(r=0.8779), and a regression equation, Y=181.03+23.56X, was found.
