Abstract:
The cultivation technique of covering film could reduce drought stress in semi-arid area.To find the effect of different covering film method on soybean,the trials of covering film on line(CFOL)and covering film between lines(CFBL) were conducted with no film covering(NFC) as CK,and the growth,physiology,photosynthetic traits and water use efficiency were investigated.Yield of CFOL increased 20.85% than CK,leaf water use efficiency (LWUE),soil water use efficiency (SWUE) and rain water use efficiency(RWUE)increased 105.16%,150.00% and 20.43%.The yield of CFBL increased 16.67% than CK,LWUE,SWUE and RWUE increased 112.68%,141.76% and 16.98%,respectively.The leaf area index（LAI）,photosynthetic index,drought tolerance and WUE were all enhanced,and yield components of pods per plant,seeds per pod and 100-seed weight were increased under the two covering film method.The results suggested that the two covering film method can all enhance grow and development,yield and WUE of soybean,and there are no significant difference between these two methods.
