摘要
试验研究结果表明 ,盆栽限水灌溉时施P明显促进小麦幼穗、根系和株高的早期生长发育 ,而对叶片含水量和叶绿素含量的影响较小 ;施P明显提高小麦地上部干物质量和产量 ,且以限水处理效果最明显 ,提高了限水处理“温麦 6”根干物质量以及“温麦 6”和“冀麦 36”
The effects of P application on root-top characteristics and yield of pot-cultivated wheat under water-limited condition are studied. The results show that P application stimulates significantly the development of fringe, root and plant height of wheat, however, has less influence on the contents of water and chlorophyll in leaves. P application increases obviously the top dry weight and yield, especially the root dry weight of ‘cv.Wenmai 6’,and fringe number of‘cv.Wenmai6’and ‘cv.Jimai 36’at water-limited condition.
