| 摘 要： | 通过大田实验研究了不同条件下覆膜对春小麦产量与水分利用效率的影响。覆膜处理均在播种后62d揭膜。由于底墒较差,覆膜后土壤干旱加剧,导致全生育期耗水量分配不合理,使前期增长的根系在中后期成为生长的冗余,进而影响水分利用效率和产量。

| Abstract: | Researched effects of plastic film mulch on spring wheat growth and water use efficiency in different conditions by field experiment. The plastic film mulch were removed after sowing for 62 days. For the serious soil drought, plastic film mulch caused unrational water consumption during whole growth period. So the increase of roots in early period became the growth redundance in later period, furthermore the yield and water use efficiency were decrease significantly. |
