玉米/辣椒间作复合群体生理效应研究Ⅰ.不同间作方式对玉米/辣椒光合速率和产量的影响

为了确定玉米/辣椒间作不同种植方式下,对玉米/辣椒光合速率和产量的影响,设置3种玉米/辣椒间作带型结构,带比分别为P/M2:3、P/M2:5、P/M2:7。从光合速率上看,在3种间作2:3、2:5、2:7中,玉米光合速率均为最高,其次是单作,辣椒光合速率最低,辣椒间作比单作光合速率降低6.78%～20.4%;从产量上看,3种间作方式在产量上均高于单产,且达到极显著水平,并以2:3间作方式的总产量最高,比对照高84.7%。综合来看,2:5间作方式产值效应最好。

Physiological Effect of Maize/Chili Pepper Intercropping Ⅰ. The Infuence of Different Intercropping Patterns on Photosynthetic Rate and Yield of Maize/chili Pepper

The research aimed to confirm photosynthetic rate and yield in different maize/chili pepper intercropping system.The stripes in maize and chili pepper in intercropping system was P/M2：3,P/M2：5,P/M2：7.In maize and chili pepper in intercropping system of 2：3,2：5,2：7,the photosythetic rate of maize intercropping were higher than sole maize,sole chili pepper and chili pepper intercropping.And compared to sole chili pepper,the photosythetic of chili pepper intercropping was a 6.78%-20.4% decline;In the three intercropping system,the yield was higher than sole maize and sole chili pepper,reached very significant level （P0.01）.When compared to maize and chili pepper in the monoculture,the intercropping of 2：3 increased 84.7.The best output effect was the intercropping of 2：5.
