- Abstract:
-
Irrigation can increase by 30 to 90 percent of the grain yeild of spring wheat with enough fertilizer applied in Guyuan county of the semi-arid loess hilly area.The amount of appropriate irrigation water is from 50mm to 100mm for effectively use water.It is shown by correlation coefficient that the grain yeild of the spring wheat increase with increasements of the dry mass of the vegetation growth stage, and decrease with increasement of the dry mass amount of the reproductive development stage.The key period of its reqirement water is the second 10-day of June.On the bas is of analysis crop-climate-soil satuation comprehansively.The suitable irrigation time should be on the later stage of the spring wheat developement under the condition of completement and health of its seedling.
