摘要
在大田条件下,以花生品种山花9号为材料,采用随机区组设计研究了夏播覆膜、夏播露地、麦田套种和麦田套种露地4种种植方式对花生单株叶面积、叶片净光合速率、干物质积累与分配及荚果产量的影响。结果表明,夏播覆膜种植方式下,花生单株绿叶面积、叶片净光合速率和干物质积累量均显著高于其他处理,为提高荚果产量奠定了物质基础;麦套露地种植方式下,花生生育后期荚果占干物质的比率和百果重均高于夏播覆膜种植;夏播覆膜与麦套露地花生荚果产量无显著差异,均高于其他处理。
Field experiment was conducted to examine the effects of different planting patterns on photosynthetic characteristics,dry matter accumulation and distribution,and pod yield of peanut Shanhua9.The experiment designed 4planting patterns such as summer sowing overbite membrane, summer sowing open field,wheat intercropping,and wheat intercropping in randomized block method.The results showed that green leaf area of single plant and photosynthetic rate and dry matter accumulation under summer sowing overbite membrane were both higher than other treatments.At later growth stage the peanut pod dry matter distribution rate and 100pods weight under wheat intercropping were higher than that under summer sowing overbite membrane,and the peanut pod yield were both higher than other treatments and had no significant difference with that of the wheat intercropping treatment.
