| 摘 要： | 本研究旨在揭示不同土壤类型条件下,小麦产量对增温的响应规律及特征。试验采用开放式增温系统对冬小麦全生育期进行全天增温,供试土壤为黑土、棕壤、风沙土、潮土、红壤和砖红壤。与常温处理相比,增温处理冬小麦株高、地上干重、穗粒数和产量分别增加了11.5%、17.7%、12.3%和12.8%;增温对生长在不同类型土壤上的小麦株高的影响不同,生长在潮土上的小麦株高增幅最大,而生长在风沙土上的小麦株高增幅最小;增温使生长在黑土上的小麦产量降低了33.3%,而风沙土和红壤上的小麦产量分别增加了44.7%和43.2%。研究表明生长在各地域的冬小麦适应气候变化的潜力存在差异,该结果可为不同气候区小麦生产适应未来气候变化提供理论指导。

| Abstract: | The research aimed to reveal the characteristics of winter wheat yield in response to elevated temperature in different soil types. The Free Air Temperature Increased (FATI) was used to mimic elevated temperature during the whole growing season. The soil samples were Phaeozem, Burozem, Aeolian sand soil, Fluvo-aquic soil, Krasnozem and Latosol zone. Results showed that plant height, above-ground biomass, grain number per spike and yield of winter wheat increased by 11.5%, 17.7%, 12.3% and 12.8%, respectively, compared with those of the control treatment. There were different variations in plant height in response to soil types under elevated temperature. The maximal increase of plant height was found in Fluvo-aquic soil, while the minimum was in Aeolian sand soil. Elevated temperature decreased the wheat yield in Phaeozem by 33.3%, while increased that in Aeolian soil and Krasnozem by 44.7% and 43.2% compared with those of the control treatment. This study indicates that the productive potential of wheat differs in different cultivated regions, and the results could provide certain reference for wheat production adaption in different climate regions to future climate change. |
