| Abstract: | In order to choose the reasonable application rate and application mode of sodic soils reclaimed with desulphogypsum,control soil moisture,soil salinity and soil sodicity in the process of soil reclamation.A pot experiment was conducted to study union response of sunflower biological indicators(height,leaf area and dry mass),physiological indicators(photosynthesis rate,transpiration rate and stomata conductance) and yield to soil moisture,soil salinity and soil sodicity.Results indicate that crop growth is ... |
