【摘要】 为了提高旱地冬小麦降水利用效率，进而达到增产，试验采用了冬小麦全生育期地膜覆盖沟穴播栽培方法。结果表明，覆膜沟穴播较覆膜穴播增产２４．２３％，较露地条播增产４６．１１％，显示了其保水抗旱增产的作用。更多还原

【Abstract】 The experiments on the mulched furrow and hole seeding method for increasing the utilized coefficient of rainfall and the yield of winter wheat in rainfed areas were conducted from 1996 to 1997. The results showed that the yield of winter wheat with film mulched furrow and hole seedings could be increased by 24.23% and 46.11% compared with the mulched hole seeding and unmulched seeding in rows respectively. The results also indicated that method has effects of drought resistance, moisture retention and the yield increase.更多还原
