| 摘 要： | 针对辽西半干旱地区玉米产量低而不稳的问题,以传统种植模式为对照,研究了垄覆膜沟种植(T1)、垄覆膜沟覆膜种植(T2)和垄覆膜沟覆秸秆种植(T3)3种一元或二元覆盖微集水模式在不同降水年型对玉米产量的影响.试验条件下,T2和T1均能缩短玉米出苗时间,提高玉米出苗率,T3能够延长玉米出苗时间,平水或干旱年型能够提高玉米出苗...

| Abstract: | This study focuses on the outstanding issues of the low and unsteadiness maize yield in semi-arid area of western Liaoning Province.Traditional cropping patterns as contrast,studied on the effect of unary or binary coverage of three micro-catchment patterns,which were ridge film mulching and furrow seeding(T1),groove ridgemulch film(T2),ridge ditch straw mulching cultivation(T3).T2 and T1 could reduce maize emergence time and increase maize emergence,T3 extend the maize emergence time,increasing maize emerg... |
