| Abstract: |
| Field experiment was conducted at experimental station of Shihezi University in 2009, which included 5 water treatments (150 mm(drip irrigation), 300 mm(drip irrigation), 450 mm(drip irrigation), 600 mm(drip irrigation) and 600 mm(furrow irrigation)) and 2 wheat varieties (Xin Chun No.6 and Xin Chun No.22). To assess wheat yield, crop coefficients and water consumption rules in spring wheat under drip irrigation, watermark was used to detect soil moisture dynamics at the depth of 0～60 cm in wheat field during the whole growing season. The results showed that, water consumption of spring wheat increased with irrigation amount. Its total evapotranspiration was 545.94 mm, and water consuming intensity was 5.35 mm/d. Evapotranspiration and transpiration intensity first increased then decrease
d with wheat growing, which reached their maxmum at heading-milking stage. Wheat yield first increased then decreased with water consumption. The crop coefficients of different growth stages was different from the data offered by FAO, whic
h was greater than that of standard conditions at initial growth stage and late growth stage. |
