【摘要】 应用¹⁴C 示踪方法研究几种植物的光合速率特征及与环境因子的关系。结果表明,光照强度、温度、锌肥及根瘤固氮等因子,对光合速率都有重要的影响,C₃和C₄作物在光合速率方面有明显差异。更多还原

【Abstract】 The Photosynthetic Characterization of some Crops and the Correlation with environmental factors were studied by ¹⁴C tracer.Theresults indicate that the sunlight illuminant intensity、the temp-erature、the Zinc fertilizer and the nitrogen fixing activity of soy-bean rhizobia effect on the photosynthesis importantly,Photosyn-thesis of C₃ and C₄ plants are defferent Significantly.更多还原
