摘　　要：采用由作物秸秆与畜禽粪便发酵产生CO2的简易发酵装置来加富大棚CO2,一次堆料可使大棚CO2体积分数维持600×10-6 13 d以上,并且可使大棚内的生菜、青菜和油麦菜等叶菜类蔬菜叶片加厚,单株鲜质量分别增加135%、322%和140%,产量分别提高127.1%、122.8%和97.9%。说明农业有机废弃物发酵加富大棚CO2,可以促进叶菜类蔬菜的光合作用,提高产量。A simple composting unit based on the use of crop residues and animal manure compost was developed to elevate greenhouse CO2 concentrations to 600 × 10^-6 for 13 days. And the average single plant weights of leaf vegetables increase 135% , 322% and 140%, respectively; The yields increase 127. 1%, 122.8% and 97.9%, too. The results show that CO2 enrichment by crop residues and animal manure compost can enhances photosynthesis of leaf vegetables and increases the yields.
