摘 要:对2∶X型玉米花生间作系统的生态生理效应和综合效益分析结果表明,间作后系统内的生态环境改善,玉米群体内的光照强度增大,光分布合理,风速增大,CO2含量增加;花生群体内光照强度减弱,CO2含量和风速略有增加。间作后后玉米叶片叶绿素含量和光合性能提高,农艺性状改善;而花生有不同程度的减弱,但随着花生行比的增加逐步得到改善。这种正相互作用和负相互作用迭加后的优势,以2∶6型和2∶8型表现较好。为发挥玉米的高产潜能,对产量效益和经济效益综合分析,提出玉米花生间作以2∶6型为最佳模式。The analytical results of ecological and physiological effects and synthetical benefit with 2∶ X model of maize and peanut row intercropping show that:Intercropped colony's ecological environment is improved in that maize group's light intensity increases,its distribution is more reasonable,the wind speed raises,the CO 2 content increases;but peanut group's light intensity decreases while the CO 2 content and wind speed increase. Intercorpped maize leaves's chlorophyll content and photosynthesis are raised, plant's properties are improved,while those of peanut are weakened,but improved gradually with peanut lines being increased.The model with 2∶6 and 2∶8 are more reasonable after contrasting with each other.In order to exert the high yield potential of maize,the model with 2∶6 is most reasonable with comprehensive analysis of yield and economic benefits.
