In order to study the variety of physiologic character, yield composition and yield result in different treatments of controlling soil water during tiller, booting and filling, high yield winter wheat were studied in cover of canopy to prevent rainwater. The results showed that there have remarkable distinctions for the winter wheat under different soil water content treatments during each growing stages. It appeared in such ways as photosynthesis rate, evaporate rate, leaf water potential. The result also showed that the later growing stages were more sensitive than the early growing stages to the soil water content and the wheat yield had been more affected by the soil water content in later growing stages. According to the photosynthesis rate, evaporate rate, leaf water potential and final yield of wheat, the suitable soil water content of water saving irrigation scheme of different growing stages were 45%~55% during tiller, 55%~60% from tiller to booting, 65% after filling.
