CO2浓度及环境温度增加对寒地粳稻不同品种倒伏风险的影响
Effect of the Increasing of CO2 Concentration and Environmental Temperature on Lodging Risk of Different Cold Rice Varieties
摘要
Abstract
In order to explore the impact of climate change which may cause the risk of rice lodging ,the con‐structed artificial climate chamber was used to regulate the concentration of CO 2 and implementation of the mo‐nitoring of environmental temperature ,taking different varieties of rice lodging resistance Longqing 1 and Longdao 5 as materials ,set the CO2 of different concentrations (contrast∶384 μmol·mol‐1 ,elevated treatment∶584 μmol·mol‐1 ) ,and the two years of environmental temperature were detected to evaluate and quantify the risk of lodging in response to climate change .The results showed that the increase of CO2 concentration was significant on the lodging resistance of different varieties ,however ,the increase of CO2 concentration and envi‐ronmental temperature effect increased for Longdao 5 of the lodging risk ,because of changes in environmental factors the plant height and biological yield increased .The ambient temperature could make rice internode elon‐gation and thus increase the risk of lodging .It was found that from the experimental data ,the increase of CO2 concentration and environmental temperature for different rice varieties showed different trends of lodging risk , therefore ,in future ,cultivation of new varieties could adapt to climate change and resist lodging risk .关键词
