Abstract
In order to apply irrigation technology better ,taking maize variety deckard 656 as test materials and set up six irrigation treatments :A laminating and no irrigation ,B Ourdoor and no irrigation ,C Laminating and furrow irrigation ,D Outdoor border irrigation ,E Outdoor drip irrigation ,F Drip irrigation under membrane , through regional comparative method ,the benefit of drip irrigation under membrane in Yanchi was studied .The results showed that drip irrigation under membrane could make the yield increase 12 .9% than outdoor drip ir-rigation ,the income increased 1 917 .0 yuan·hm-2 ,water use efficiency increased 16 .2 kg·mm-1 ·hm-2 ,by 20%increase ,and it increased yield 21 .5% ~27 .5% than normal irrigation ,water use efficiency increased 71 .0~71 .8 kg·mm-1 ·hm-2 .关键词
