　　通过盆栽试验研究了不同秸秆覆盖水平和玉米/大豆间作系统中根系互作对玉米的影响。结果表明：秸秆覆盖和根系互作可增加玉米成熟期单株绿叶面积和不同生育时期的叶绿素含量，且根系互作的作用随覆盖水平的提高而增强；玉米成熟期的植株含水量和根伤流显著受到覆盖的影响，而受根系互作的影响不显著（ P＞0．05）；覆盖和根系互作可提高玉米光合速率、气孔导度和蒸腾速率，而降低胞间CO2浓度，其中相同隔根处理下， T1和T0间的差异显著；覆盖和根系互作可改善玉米产量各构成因素，并提高成熟期单株生物产量和经济产量。相关分析发现，玉米单株绿叶面积、叶绿素含量、根伤流速度、光合速率均与产量存在直线正相关关系。得出，覆盖和根系互作有利于改善玉米生理特性，提高产量，且根系互作的优势作用随覆盖水平的提高而增强。

A pot experiment was conducted to study the effect of different straw mulching levels and root interaction in maize/soybean intercropping system on maize .The results showed that straw mulching and root interaction increased the green leaf area per maize plant at maturity stage and the chlorophyll content of different growth stages ,and the effect of root interaction was enhanced with the increase of straw mulching level .The plant water content and the root bleeding sap of maize at maturity stage were significantly affected by mulching ,but not affected (P>0 .05) by root interaction . Mulching and root interaction increased the photosynthetic rate ,stomatal conductance ,transpiration rate of maize ,and reduced the intercellular CO2 concentration .With the same root separation ,the differences between the treatments T1 and T0 were significant .Mulching and root interaction improved maize yield components ,and increased biological and eco-nomic yields per plant at maturity stage .Correlation analysis revealed that the green leaf area per maize plant ,the chloro-phyll content ,the root bleeding sap rate ,and the photosynthetic rate were all linearly positive correlated with maize yield .In conclusion ,the mulching and root interaction improved maize physiological characteristics and increased yield . The beneficial effect of root interaction was enhanced with the increase of the straw mulching level .
