秸秆还田方式和施肥对冬小麦生理特性及产量的影响
Effects of Residue Returning Methods and Fertilizer Application on Physiological Characteristics and Yield of Winter Wheat(Triticum aestivum)
摘要
Abstract
A field experiment was carried out to study the effects of the different straw returning methods and fertilizer application on physiological property,SPAD value and the yield of winter wheat.The results indicated that straw returning and fertilization influenced significantly the daily change of physiological property of winter wheat.The peak value of daily photosynthetic rate (Pn) was deferred under the treatments of straw buried between lines of crops (ISFR),and fertilization substantial increased the daily change in photosynthetic rate.Straw returning treatments (ISFR,SFR) inhibited the photosynthetic rate during the early stage of wheat growth,and promoted the stomata conductance (Cond) and photosynthetic rate of the flag leaf of wheat at the late growth stage under the ISFR treatment compared with NSFR and SFR.In whole developing stage of wheat,ISFR treatment had the bigger variation scope of photosynthetic rate and the highest peak value.Different straw returning methods did not influence significantly SPAD value and yield of wheat(P＞0.05),but fertilization increased significantly physiological property,SPAD value in the late growth and yield of wheat(P＜0.05).关键词
