【Abstract】 Using the orientational observatory data from 1994 to 1996 in Wuwei station, biological features of spring wheat’ sall organs’ forming are analysed. By using Linorclan ways, the amount of water needing and water lacking in spring wheat’s various growing periods in the east part of Hexi Corridor is computed which is about to be the basis of the land’s irrigation, and further the influence of soil water on the forming of spring wheat’s dry matter weight is analysed.更多还原
