英文简介 | The mulch measures regulation mechanism of soil water-temperature-salt movement and crop high yield is the core of the research on farmland mulch technology. This project, aiming at the production practice problems about straw mulching ecological adaptability and film mulching residual film difficult recovery, intending to combine the two kinds of mulch, drawing lessons from national and international theories of the soil water-temperature-salt migration about farmland mulch, using the methods of field test and indoor analysis, setting two dominant factors: mulching mode and irrigation quota, will analyze soil water storage and soil moisture movement in the edible sunflower field, and study soil temperature effect and soil water-temperature movement, and investigate the temporal and spatial distribution of soil salinity and water-salt movement law, and explore the two factors influence on the growth and yield with edible sunflower, for clearing the water-saving effect and the regulation mechanism of soil water storage under irrigation on film padded with crushed wheat straw (IFCWS), in the Northwest Arid Regions of China, and ascertaining the soil water-temperature-salt movement law under IFCWS, and revealing the intrinsic mechanism of inhibiting soil salt accumulation into the surface under IFCWS, and proving the regulation ways on soil water-temperature-salt migration and edible sunflower yield under IFCWS, and forming the edible sunflower technical application mode of the IFCWS, in the Northwest Arid Regions, China. The completion of this subject would provide the scientific theory basis for the sustainable use of water and soil resources in the Northwest Arid Regions, China. |
