In order to verify the effects of climate warming on winter wheat production in semi-arid rain-fed areas, and to understand the effects of increasing temperature and water on growth characteristics, yield and photosynthetic-transpiration relationship of winter wheat, the experiment set different temperatures (no temperature increase, 1.5℃ increase) and water gradient [full water supply (lower limit of irrigation water is 70% field capacity) and water deficit (irrigation water is 75% of full water supply)], a total of four treatments are temperature increase-adequate water supply (R-g), temperature increase-water deficit (R-d), no temperature increase-adequate water supply (N-g) and no temperature increase-water deficit (N-d). Using electronic radiation infrared heater (American Kalglo, model MRM2420) was used to achieve the warming effect. The irrigation method was drip irrigation. Type of drip irrigation belt is∮16mm patch drip irrigation belt. The distance between drip heads is 1 meter and there are 3 drip heads. The flow rate of drip heads is 2-2.2 L. The effects of climate change on plant height, leaf area, chlorophyll content, yield and photosynthesis and transpiration coupling of winter wheat were simulated. The results showed that: (1) During the five observations of plant height and leaf area, at the same temperature level, under water supply was sufficient (R-g)/(N-g) of winter wheat plant height is higher than water deficit under the condition (R-d)/(N-d) the plant height under full water supply increased by 1.5%-12.9% compared with that under water deficiency. At the same moisture level, the temperature increase condition (R-g)/(R-d) lower plant height is higher than that without warming (N-g)/(N-d) the plant height under elevated temperature increased by 8.5%-53.6% compared with that under no elevated temperature. (2) At the same temperature level, the leaf area of winter wheat under R-g/N-g condition was larger than that under R-d/N-d condition, and the leaf area under sufficient water supply increased by 2.5%-29.2% compared with that under water deficit condition. At the same water level, the leaf area of R-g/R-d was larger than that of N-g/N-d. The first four data showed that the leaf area of R-g/R-d increased by 1.3%-41.6% compared with that of N-g/N-d. The last observation data showed that under the water deficit level, the leaf area of R-d was smaller than that of N-d, Leaf area decreased by 6.9% under temperature increasing compared with that without temperature increasing. Comprehensive analysis showed that the synergistic effects of 1.5℃/ no temperature increase and sufficient water supply had positive effects on plant height and leaf area of winter wheat, while the synergistic effects of 1.5℃ increase and water deficit had negative effects on winter wheat. (3) At the same temperature level, thousand seed weight and grain yield of R-g/N-g treatment were higher than that of R-d/N-d treatments increased by 0.2% and 24.6% respectively under the condition of increasing temperature, and by 3.6% and 37% respectively under the condition of no increasing temperature. At the same moisture level, R-g/R-d thousand seed weight and grain yield of winter wheat were more than N-g/N-d under the condition of adequate water supply, they were 1.9% and 12% higher respectively, and 5.5% and 23.4% higher respectively under the condition of water deficit. (4) In the coupling relationship between photosynthesis and transpiration, the transpiration rate and photosynthetic rate are horizontal and vertical coordinates respectively, and the slope of linear relationship in the coordinate represents the ratio of photosynthetic rate to transpiration rate (water use efficiency). There is a significant positive correlation between photosynthesis and transpiration of winter wheat. R2 of R-g, R-d, N-g and N-d treatments were 0.91**, 0.88**, 0.96** and 0.89**, and the slopes of linear regression equations were 2.68, 1.86, 4.40 and 2.71. At the filling stage, R2 of R-g, R-d, N-g and N-d treatments were 0.66**, 0.59*, 0.89** and 0.74**, and the slopes of linear regression equations were 1.57, 1.28, 3.89 and 3.79. These results indicated that there was a good linear coupling relationship between photosynthesis and transpiration in winter wheat leaves. In conclusion, winter wheat yield in the semi-arid rain-fed area of north China Plain may be further improved under the expected warming conditions.
