我省近年来对充分利用太阳能提高农作物的产量已引起各方面的重视。为了探明影响水稻产量的主要内在生理及外在生态因素,我们采用了品种比较的方法,利用佛山分析仪器厂的FQ—W—CO_2红外线气体分析仪,研究了影响水稻产量的重要因素—群体光合作用。初步探讨了叶面积、叶片开张角、太阳能与水稻产量及群体光合率的关系。一、叶面积指数与产量水稻产量90％以上来自光合产物。稻叶是进行光合作用、合成碳水化合物的主要器官,它与产量的构成有密切关系。我们用叶面积指
In recent years, our province has drawn great attention from all aspects to making full use of solar energy to increase crop yield. In order to explore the main physiological and ecological factors that affect the yield of rice, we used a variety comparison method. Using the FQ-W-CO_2 infrared gas analyzer at Foshan Analytical Instrument Factory, we studied the important factors affecting rice yield-population Photosynthesis. The relationship between leaf area, leaf opening angle, solar energy and rice yield and photosynthetic rate was also discussed. First, the leaf area index and yield More than 90% of rice yield from photosynthetic products. Inaba is the main organ for photosynthesis and carbohydrate synthesis and is closely related to the composition of the yield. We use the leaf area refers to
