摘 要：
通过试验测试揭示了自然扩散状态下的畜菜互补生态系统内温室中CO_2分布不均,存在着较大的浓度梯度以及畜菜配比不当等问题。设计并试验测试了塑料风管传输装置及兼有CO_2传输功能的地下热交换系统,两者对改善系统内的CO_2分布,提高蔬菜产量起到了明显作用。

摘 要：
Under natural diffusion condition, the CO2 concentration along the vegetable growing area of plant and animal complementary ecosystem is uneven. The ratio of plant growing area to animal raising area varies greatly in the present system that causes CO2 too high or too low. These two problems are revealed in this paper by experiments. A CO2 transferring installation composed of propeller fan and perforated film duct and an underground heat exchange system combining CO2 transfering function are designed and tested. The two methods possess a high effect on the promotion of vegetable production.
