title: [Effects of increasng field temperature on growth, development and yield of spring wheat in semi-arid area].
abstract: A field infrared temperature-increasing simulation experiment was conducted to investi- gate the effects of air temperature increases (0, 1 and 2 °C ) on growth, development and yield of spring wheat at the Dingxi Arid Meteorology and Ecological Environment Experimental Station of the Institute of Arid Meteorology of China Meteorological Administration. The results showed that the growth period of spring wheat was shortened by 7-11 d when the temperature increased by 1-2 °C. The plant height and leaf area index increased at early growth stage, decreased after entering the jointing stage, and warming 2 °C had a higher effect than warming 1 °C. Warming treatment induced an obvious decrease in chlorophyll content, especially from late grain filling stage to milk ripe stage. Compared with the control, increasing temperature by 1-2 °C decreased the spring wheat yield by 25.4%-45.5%, mainly due to obvious decreases in number of grains and grain mass per panicle. Water consumption of 0-100 cm soil horizons increased with the increase of temperature, while the variation tendency of water consumption of 100-160 cm soil horizons was not obvious.
