Abstract: Planting pattern affect photosynthetic characteristics of maize. In this paper,we study the effects of planting patterns on the photosynthetic characteristics of two maize cultivars(Beiyu 288 and Xianyu 335) in two planting patterns narrow-wide rows of P1,170 cm + 30 cm(6. 4 plants / m2); P2,90 cm + 40 cm(6.4 plants/m2), and CK,uniform row of 65 cm(6. 4 plant / m2). The SPAD value of leaves,chlorophyll fluorescence and photosynthetic parameters were compared at ear leaf in this experiment. The significant difference of leaf SPAD value among measured was detect,wide and narrow row planting pattern show a certain degree of superiority. Among three different planting,ear leaf chlorophyll fluorescence parameters were quiet differences in Fo; Fm and Fv / Fm at a critical growth stages were significantly different,and net photosynthetic rate of leaf in P1 and P2 was significantly higher than CK,experimental results show that compared with traditional cultivation methods,wide and narrow row planting patterns had promoted photosynthetic characteristics.
