摘要： 为河西走廊绿洲罐区全膜覆土穴播、垄作沟灌大麦栽培模式的推广提供科学依据。在大田条件下研究全膜覆土穴播、垄作沟灌栽培及传统平作条播对大麦生长发育、干物质积累动态和产量。全膜穴播栽培模式有利于大麦发芽，提高出苗率，加快大麦生长发育进程，不同程度地增加了大麦叶片数、LAI、单株干物质积累量；垄作沟灌栽培模式有利于大麦千粒重的提高且具有晚熟效应。全膜穴播处理产量较平作条播和垄作沟灌分别高出10.9%和15.31%。全膜穴播栽培模式最有利于大麦生长发育及高产。

Abstract: The aim was to provide scientific basis for popularization of over film-mulched soil cultivation and controlled traffic tillage with ridge in Hexi corridor oasis irrigation district. The growth and development, dynamic accumulation of dry matter and output of barely were studied under field conditions in three cultivation modes, including over film- mulched soil cultivation, controlled traffic tillage with ridge and conventional planting strip cropping. The over film-mulched soil cultivation was beneficial to barley sprout, enhanced emergence rate and accelerated growth and development of barely, and increased leaf number, LAI and dry matter accumulation quantity to different extent; the controlled traffic tillage with ridge irrigation improved the thousand seed weight of barley and had late- maturing effect. Compared with conventional planting strip cropping and controlled traffic tillage with ridge irrigation, the output in over film-mulched soil cultivation increased 10.9% and 15.31% , respectively. The over film- mulched soil cultivation was most beneficial to growth, development and good harvest of barley.
