Abstract

A pot experiment was designed under drought stress condition to study the effect of different starter nitrogen fertilizer on photosynthetic characters in the leaves of relay strip intercropping soybean at branching stage. The Pn, Gs, Tr were measured, WUE was calculated. The results showed drought stress significantly decreased Pn, Gs and Tr. Mild drought stress reduced Ci, moderate drought stress and severe drought stress increased Ci. Under the same starter nitrogen fertilizer WUE was higher as the soil water content reduced. WUE of moderate drought stress was higher than that of mild drought stress, WUE of mild drought stress was higher than that of severe drought stress, and WUE of severe drought stress was higher than that of control. Appropriate starter nitrogen fertilizer was benefit to improve Pn, Gs and Tr, reduce Ci.
