Abstract
On the base of low phosphorus soil,studying biological effect of phosphorus fertilizer application,the results showed phosphorus application behaved significant biological effects at the whole growing stage.Phosphorus application compared with no-phosphorus treatment,root dry weight increased 26.5%-188.2% at seeding stage,max-leaf area index increased 0.25-0.58,LAD and photosynthesis productivity improved significantly,grain filling accelerated,1 000-grain weight and yield increased remarkably.
