不同宽窄行种植方式下玉米穗位叶的光合生理特征
The Comparison of Photosynthetic Characters on Ear Leaf under Different Wide-narrow Planting Patterns in Maize
摘要
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 photosyn-thetic 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 differ-ent 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.关键词
