| 中文摘要: |
| 目前研究CO2浓度升高对农作物的影响主要集中在光合作用、生理生态反应和产量形成等方面,对重金属污染胁迫下CO2浓度升高对水稻生长发育和品质影响的研究甚少。本文通过详述Cu、Cd等重金属污染条件下,CO2浓度升高对水稻生长发育及稻米品质的影响,揭示重金属污染条件下CO2浓度升高影响Cu、Cd在土壤-水稻系统中的运移状况及其稻米营养品质方面的相关机制,为CO2浓度持续升高背景下复合污染农田风险评估、农产品安全调控提供科学依据,也对于预测未来气候条件下人类稻米品质变化及水稻品种的选育意义重大。 |
| 英文摘要: |
| More researches highlight the photosynthesis, physiology, and production of crops under elevated CO2 levels. A few researchers fo-cus on the influence of CO2, along with heavy metals, on the growth and quality of paddy. In this paper, the processes of copper and cadmium on the growth and grain quality of rice in elevated CO2 levels were summarized, and the subsequent quality of paddy was studied. The study provides reference for the risk assessment of compound-contaminated soils, safe production and controlling of crops, and quality prediction of crops under the continual increase of global CO2 level in the future. |
