摘要： 通径分析结果表明：根际高浓度的ＣＯ２是影响普通地膜覆盖番茄根、叶活力的主要因素。有孔地膜覆盖使土壤水气通畅，根际ＣＯ２浓度降低，进一步提高根系伤流量，增加叶片叶绿素含量，延缓了番茄早衰进程，从而促进了番茄早熟增产
关键词: 有孔地膜, 番茄, 根际CO_2浓度
Abstract: The path analysis in this paper showed that high CO 2 concentration of root zone under the plastic film mulch was the major factor which limited the activities of roots and leaves of tomatoes. Perforated film mulch improved soil aeration,decreased the CO 2 concentration of root zone,remarkably delayed senescence of the plants,accelerated the photosynthesis of leaves and supply capacity of roots,and eventually resulted in high early yield and total yield.
