土壤含盐量对有机基质栽培番茄生长、光合特性及产量的影响
Effects of Soil Salinity on Growth, Photosynthetic Characters and Yield of Tomato Cultivated in Organic Substrate
摘要
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 Tl, 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 Style of Organic Substrate Culture.关键词
