| 摘 要： | 对不同稻草覆盖量下早稻茬免耕秋玉米光合生理指标测定的结果表明：稻草覆盖能增强玉米光合速率、蒸腾速率、气孔导度和提高叶片水分利用率，且随着稻草覆盖量的增加而增加。覆盖稻草量在9000～12000 kg／hm^2可达到改善秋玉米光合特性的效果。

| Abstract: | The influences of straw mulching on photosynthetic characteristics of autumn maize were studied in early -rice stubble and no -tillage field.Results showed that straw mulching could increase the photosynthetic rate,the transpiration rate,the stomatal conductance,the water utilization efficiency of the maize leaf blade,the effect got more significant with more straw mulching.As for improving photosynthetic characteristics of autumn maize,the amount among 9 000 ~12 000 kg/hm^2 and of rice straw mulching was suitable in south Hunan province. |
