- Abstract:

In order to explore the effects of global warming on the growth of wheat and the root soil characteristics in China, we monitored and measured the the growth characteristics of wheat and soil enzyme activity and respiration in root area by using the open-top chamber (OTC) by three years, providing the basic data for improving the quality and the yield of wheat of China. The results are as follows:In the whole of the growing season, the soil temperature of OTC and CK first increased and the decreased with the seasonal change with the order of OTCCK. The difference reached the maximum in the rejuvenating period and reached the minimum in the mature period. The simulated temperature enhancement increased soil respiration and soil enzyme activity in root zone of the wheat during the growth period of wheat. Soil urease, invertase, acid phosphatase and sucrase and soil respiration showed increased at first and then decreased with the seasonal change. Soil enzymatic activities and soil respiration rate of OTC was greater than those of in the same growth period. In the whole growing season of wheat, soil respiration rate and soil enzyme activity had the significant exponential relationship with soil temperature, respectively (p<0.05). The simulated temperature enhancement increased the growth characteristics of wheat in the mature period of wheat. Wheat height, leaf area index and grain number per area of OTC were greater than those of CK (p<0.05). There were no significant differences in specific leaf weight and R/S (p>0.05). Thesimulated temperature enhancement is benefit to the growth of wheat, and improves soil enzyme activity and soil respiration in the root zone of wheat.
