Effects of supplementary irrigation on the growth of film-mulched spring wheat in Hetao irrigation area during heading stage
In order to increase the 1 000-grain mass and yield of film-mulched spring wheat in Hetao irrigation area, we monitored the effects of different supplementary irrigation amounts of 90, 70 and 50 mm water during the heading stage, respectively, on soil moisture and growth of film-mulched spring wheat...

| description | In order to increase the 1 000-grain mass and yield of film-mulched spring wheat in Hetao irrigation area, we monitored the effects of different supplementary irrigation amounts of 90, 70 and 50 mm water during the heading stage, respectively, on soil moisture and growth of film-mulched spring wheat, taking the conventional irrigation as the control. The results showed that the soil moisture content of film-mulched spring wheat increased at the flowering stage, filling stage and maturity stage by different supplementary irrigation amounts during the heading stage; and the higher the supplementary irrigation amounts were, the higher the soil moisture content and soil moisture evapotranspiration strength, the later the maturity of spring wheat, the less the number of sterile spikelets, and the higher the 1 000-grain mass and grain yields were. The smaller the supple-mentary irrigation amounts were, the higher the yield increase intensity was, but the different supplementary irrigation amounts during the heading stage had no significant effect on the economic coefficient, soil water use efficiency and soil water production efficiency of film-mulched spring wheat. In conclusion, the water quantity of irrigation 50-70 mm should be supplemented in the Hetao irrigation area during the heading stage, which can effectively increase the 1 000-grain mass and yield of film-mulched spring wheat. |
