Abstract: The maximum water-consumption of spring wheat in semi-arid area of west Liaoning is atthe stages of jointing-heading and milking,but the daily maximum consumption is at flowing stage.Soil moisture regime is decisive to water-consumption of spring wheat.Under favourable conditions of water supply,the moisture in lower soil layers is relatively less effective for increasing yield.A reasonable irrigation system can raise the water utilization efficiency of wheat.310—340mm can be used as a reference value of water requirement and consumption of spring wheat in west Liaoning.Winter irrigation is significant for the growth anddevelopment of spring wheat.
Key words: Accumulation of inorganic nitrogen, Mono-harvesting farmland, Non-growing season
