| 摘 要： | 以正常土壤中的有机基质栽培为对照（CK），在含盐量分别为5‰（T1）、10‰（T2）、15‰
（T3）的土壤中，利用半隔离式有机基质栽培技术栽培番茄，研究了有机基质栽培条件下盐渍土中盐分的
迁移规律及对番茄的生理生化特性和产量的影响。结果显示：T1、T2 和T3 处理的基质下部土壤中的Na+
含量大幅降低，番茄叶片中Na+含量、株高、茎粗、干物质积累量、叶片净光合速率和产量等指标与对照
相比无显著差异。表明在含盐量低于15‰的土壤中，盐分未对半隔离式有机基质栽培的番茄产生明显影响。

| Abstract: | Taking tomato（Lycopersicon esculentum Mill.） cultivated in organic substrate of normal
soil as the control（CK），an experiment was conducted using Half Isolated Style of Organic Substrate
Culture（OSC）to plant tomato in saline soil with 3 different salinity levels of 5‰，10‰ and 15‰，
respectively and to study the regulation of Na+ migration and the effects of Na+ in soil on physiological
characteristics and yield of tomato．The result showed that the Na+ contents in the soil under the substrate
was leached by T1，T2，T3 treatments；and the plant height，the stem diameter accumulated amount
of dry matter，the leaf photosynthetic rate，the yield of tomato and the Na+ content in tomato leaf had
not significant differences with that of the CK．The results indicated that the soil with less than 15‰ salt
content had not effect on tomato cultured by Half Isolated Styl e of Organic Substrate Culture． |
