不同种植方式沟播沟灌对夏玉米生长发育的影响

Effects of Furrow Drilling and Irrigation of Different Planting Modes on Growth and Development of Summer Maize

研究了3种种植形式下2种灌溉方式对夏玉米生长发育及产量的影响。结果表明：灌溉方式和种植形式对玉米产量性状及产量影响不大。采用沟播沟灌方式,可以用较少灌水量取得与常规畦灌同样的产量,说明沟播沟灌是一种有效的节水途径。综合考虑产量和节水因素,认为采用60 cm等行距种植效果较好,采用50~70 cm大小行沟播沟灌效果次之。

The effects of furrow irrigation of different planting modes on the growth and development of summer maize were studied.The results showed that the effects on the yield characters and yield were not significant.The yield of furrow drilling and irrigation was same to that of border irrigation,that was to say,furrow drilling and irrigation was an effetive water-saving way.Comprehensively considered the yield and water-saving,the effect of 60 cm row space sowing was better,then two row spaces sowing（50-70 cm）.
