Study on soil salt distribution with drip irrigation under mulch in cotton boll period in south Xinjiang
南疆膜下滴灌棉花花铃期土壤盐分分布研究

Drip irrigation under mulch increases the risk of soil secondary salinization while it saves water resources, which is adverse for agriculture production. The typical land with drip irrigation under mulch was selected in cotto boll period, and soil samples were collected from different layers from the location under the emitter, the location between cotton lines and the naked location to analyze the distribution law of soil salt in the horizon and the vertical orientation by measuring soil salt content. The result showed the soil salt distribution could be different from the usual law by the different conditions such as drip irrigation models. It would be useful to instruct the local agriculture production to understand the soil salt distribution.
