云南稻-鸭共作模式对水稻光合产物的影响

Effects of Rice(Orza sativa L.)-duck Integrated Farming on Photosynthates of Rice Leaves

[目的]研究云南稻-鸭共作模式对水稻(Orza sativa L.)光合产物的影响,探讨稻鸭共作模式的可行性。[方法]采用田间对比试验,随机区组排列。测定指标为水稻叶片叶绿素含量和光合效率。[结果]稻鸭共作模式下水稻叶片气孔导度、细胞间隙CO2浓度、叶绿素含量有所增加,提高了水稻的净光合速率,增加了水稻的生物和经济产量。[结论]该研究可为稻鸭共生模式技术的推广应用提供科学依据。

[Objective] The purpose was to study the effects of rice-duck integrated farming on photosynthates of rice leaves,and discuss its feasibility.[Method] The randomized block design was used to carry out field comparison test,and the measuring indices were chlorophyll content and photosynthetic efficiency of rice leaf.[Result] The results showed that the rice-duck integrated farming increased leaf stomatal conductance,intercellular CO2 concentration and chlorophyll content of rice,improved its net rate of photosynthesis,then heightened its biological and economical output.[Conclusion] The study provides a scientific basis for popularization and application of rice-duck integrated farming.
