Research on Diurnal Variations of Photosynthesis of Zizyphus mauritiana Lam under Different Soil Moisture in Dry-hot Valley of Yunnan
摘要
Abstract
[ Objective ] The research aimed to compare the difference of diurnal variations of of photosynthesis of Zizyphus mauritiana Lam under different soil moisture. [ Method] Photosynthetic parameters in leaves of two-planted Zizyphus mauritiana Lam in dry-hot valley of Yunnan were determined. [ Result] The curves of diurnal variation of Pn,Tr and Gs were typical double-peaked, and three factors were decreased gradually with the decrease of SWC. The change of Pn was related mainly to stomatic factors. [ Conclusion] Under four different soil moisture,the best soil moisture with photosynthesis was mesh word sulcus buried grass furrow irrigation + soil surface death cover.关键词
