3年研究表明：与传统的露地条播种植方式相比，旱区冬小麦地下渗灌与膜上穴播栽培技术体系相结合，能更好地发挥节水增产效应，提高水分利用率，小麦植株发育健壮，干物质积累增多，分蘖成穗增加，群体光合能力增强；更为显著的是，在产量三因素中，每公顷成穗增加了93.0万，穗粒数平均增加1.8粒，千粒重提高了2.1g，每公顷增产2127.0kg，增产率为47.58%，净增产值1265.1元。
3年研究錶明：與傳統的露地條播種植方式相比，旱區鼕小麥地下滲灌與膜上穴播栽培技術體繫相結閤，能更好地髮揮節水增產效應，提高水分利用率，小麥植株髮育健壯，榦物質積纍增多，分蘗成穗增加，群體光閤能力增彊；更為顯著的是，在產量三因素中，每公頃成穗增加瞭93.0萬，穗粒數平均增加1.8粒，韆粒重提高瞭2.1g，每公頃增產2127.0kg，增產率為47.58%，淨增產值1265.1元。

Compared to traditional drilling on bare farmland, the plantingtechnique of film covering under the condition of permeable irrigation has made both the wheat yield risen and water saved, this has improved the efficiency of water utilization. The technique has made the wheat plants strong and healthy in development, much more dry matter accumulated, the effective ears from tillerings and photothesis of wheat colony increased. Especially, effective ears per hm\+2 which is the first one of the three factors concerned with yield increased by 930 thousand, the average number of grains in a ear increased by 1.8, the weight of a thousand grain increased by 2.10 g. All of them have made the total yield per hm\+2 increased by 2 127 kg, as much as 47.58% of yield-increase and 1 265.1 yuan of net output value were achieved.
