摘要：

为改善根系呼吸环境，试验采用基质下部铺设网状拱架，通过调整通气空间大小，创造不同的根区气体浓度，以无通气处理为对照,研究不同通气处理对番茄植株生长的影响。结果表明：根区CO2浓度变化幅度较大，其中CK 的CO2浓度最高（2.1％）；而根区O2浓度变化幅度较小，T2处理最高（19.3％），并且T2的长势在整个过程中表现最好，根系活力和硝酸还原酶都表现为T2＞T3＞T2＞CK；通气处理有助于干物质的积累，在生长后期T2处理表现出了较高的产量和营养品质。

Abstract:

With the method of change the size of ventilation space of root-zone .In this paper ,The effects of differentt root-zone environment on tomato was studied.The results showed that contents of CO2 and O2 in root-zone were significantly different among the four manners of ventilation, CO2 content of CK treatment was the highest（2.1﹪）, and O2 content of T2 treatment was the highest（19.3％）. But T1 treatment had a high value in the aspect of root activities and NR; T2 treatment had the best yield and nutration quality . Together, T2 treatment was better to used .
