Abstract: In order to study on the effect of black peanut's growth and development under plastic-film and straw mulching patterns,we carried out YH1 and LH3 as experimental material in field condition,which was used for analyzing the change rule of leaf photosynthetic traits and grain quality traits. According to the results,plastic and straw mulching were shown to improve moisture condition in plow layer soil,which also promoted black peanut plants' main stem height,lateral branch length and branch number. Effects of whole plastic-film mulching pattern were better than others and the control. Whole plastic-film mulching pattern could increase LAI,Pn,Tr,Ci,Gs value and photosynthetic efficiency significantly,which was better than half-film and straw mulching patterns. Four patterns could increase grain oil content,crude protein,oleic acid content quality traits value in different levels,but this change was not significant. Mulching patterns had more facilitating effect in grain Zn content than Se content. YH1 had better cultivars' stability,while more environment resiliency was shown in LH3.
