title: [Effects of straw mulching and irrigation on solar energy utilization efficiency of winter wheat farmland].
abstract: The study showed that straw mulching decreased the basic seedlings and tillers of winter wheat and the leaf area index (LAI) at earlier growth stage, but increased the LAI at latter growth stage. Straw mulching and irrigation reduced the transmittance and reflectance of PAR, resulting in the increase of PAR capture ratio mainly at the height of 40-60 cm. The solar energy utilization ratio of grain was decreased by straw mulching, while that of stem and leaf was increased. The total solar energy utilization efficiency of winter wheat could also be increased by straw mulching.
