Popis: Photosynthesis controls crop growth and yield, and differences in planting methods and soil moisture can significantly affect the photosynthetic characteristics of crops. Grain filling stage and milking stage are two important stages of maize from flowering to maturity, which are essential for maize grain formation and dry matter accumulation. The effects of different mulching and drip irrigation patterns on the photosynthetic characteristics and maize yield at grain filling and milking stages were investigated in a field experiment in the Hetao Irrigation District, Inner Mongolia. Maize leaf photosynthesis during the grain filling stage was not significantly different under the different treatments. During the milking stage, photosynthetic and transpiration rates under both partial (B光合作用是作物生长发育和产量形成的基础,栽培方式和土壤含水量变化显著影响作物的光合作用.灌浆期和乳熟期是玉米花粒期2个重要阶段,是玉米籽粒形成和干物质积累的关键时期.通过大田试验研究了河套灌区不同覆膜方式与滴灌水平对不同生育时期玉米光合特征及产量的影响.结果表明: 灌浆期玉米叶片光合特征在不同处理下无显著差异,乳熟期净光合速率和蒸腾速率在半覆膜(B
