美地那对土壤溶液含盐量变化的影响

在田间利用盐分传感器对土壤溶液电导率连续观测表明，施用美地那可在灌水期间增加表层，10cm,30cm，深土壤溶液盐分淋洗量，在未灌水期间抑制这些土层土壤溶液中盐分累积,60cm深土壤液电导率变化较以上土层缓和，田间施用美地那对该层土壤液含盐量影响不大。

The Variation of Salt Contented in Soil Solution in the Farmland Applied Meidina

Cat No5500 soil salinity sensors were used in a field plot experiment to monitoring the variation of saltiness of soil solution with different depths.Meidina,a microorganism fertilizer,applied in the field plots.The results were as follows:Being applied the Meidina,a larger amount of salt would be leached from the surface soil and soil underground 10cm and 30cm during irrigation time.Also being applied the Meidina,a fewer amount of salt would be accumulated in surface soil and soil underground 10cm and 30cm during no irrigation time.The variation of saltiness of soil solution underground 60cm was less than of above layers.And applying Meidina to farmland would not influence the saltiness of the soil solution underground 60cm.
