河西灌区浅埋滴灌对春玉米生长发育及产量的影响
Effects of Shallow Buried Drip Irrigation on the Growth,Development and Yields of Spring Maize in the Hexi Irrigation Areas
摘要
Abstract
To explores the impact of shallow buried drip irrigation on the growth and development of spring maize and its yields,aiming to enhance the quality and output of maize in the Hexi irrigation areas and improve the efficient utilization of water resources,2 treatments,shallow buried drip irrigation and mulched flood irrigation,were investigated for their effects on the growth period,plant height,stem diameter,dry matter accumulation,yield and economic benefits of the maize variety Jinqing 707.Results showed that compared with mulched flood irrigation,shallow buried drip irrigation delayed emergence by 3 days and extended the growth period by 5 days.It increased dry matter accumulation by 3.97%,decreased plant height by 5.28%and increased stem diameter by 5.36%,indicating that shallow buried drip irrigation can enhance the lodging resistance of maize.Moreover,shallow buried drip irrigation increased maize yield by 9.25%,100-grain weight by 2.3 g,and net profit by 3 540 Yuan/ha.These findings suggest that in practical production,shallow buried drip irrigation has higher economic benefits and more significant water-saving effects compared to mulched flood irrigation.关键词
