| 摘 要： | 采用裂区设计，研究了秸秆覆盖及免耕对土壤温度、容重及棉花功能叶SPAD值、光合特性、生育性状等的影响。结果表明：免耕降低土壤温度、容重以及棉花的净光合速率、气孔导度、胞间CO2浓度、蒸腾速率，但功能叶SPAD值为免耕>翻耕；秸秆覆盖降低土壤温度，提高土壤含水量；免耕下秸秆覆盖较地膜覆盖和露地提高土壤容重及棉花的气孔导度、胞间CO2浓度、蒸腾速率，翻耕时结果与此相反；翻耕处理棉花长势强于免耕，但单株结铃数差异不显著；秸秆覆盖较露地能显著提高棉花铃数、铃重和衣分；秸秆覆盖量越大，功能叶SPAD值越小，但产量越高。秸秆覆盖免耕下棉花光合能力和产量表现均差于翻耕，但产量与露地及地膜覆盖处理间的差异不显著。 |

| Abstract: | The experiment was conducted with the split plot design to study the effects of straw mulch and zero tillage on the temperature and bulk density of soil,the SPAD value of functional leaves,photosynthetic characteristics and growth situation of cotton.The results showed that the temperature and bulk density of soil,the net photosynthetic rate (Pn),stomatal conductance (Gs),inter CO 2 concentration (Ci),transpiration rate (Tr) of cotton were lower in zero tillage treatments than in tillage treatments,while th... |
