覆膜穴播栽培是近年来在西北旱区发展起来的1种小麦节水栽培模式。为验证其在华北地区应用的可行性,2010～2011年在河北省曲周县中国农业大学冬小麦/夏玉米高产高效万亩示范基地,研究了在灌溉施肥和非灌溉施肥条件下覆膜与不覆膜处理对冬小麦生长及产量的影响。结果表明:覆膜冬小麦返青期表层土壤含水量明显高于不覆膜处理;覆膜可显著增加冬小麦株高、穗长、小穗数和穗粒数,显著降低不孕小穗数,从而明显提高产量;在春季灌溉施肥、不灌溉不施肥条件下,覆膜栽培的产量分别较不覆膜处理增加45%和21%;覆膜处理的经济效益明显高于不覆膜处理,表现出较好的应用前景。
Film-mulching cultivation is a kind of wheat water-saving cultivation mode developed in the arid region of northwest China in recent years. To verify the feasibility of its application in North China, from 2010 to 2011 in Quzhou County, Hebei Province, China Agricultural University winter wheat / summer maize high yield and high mu demonstration base to study the application of irrigation and non-irrigated fertilizers under the conditions of film and not Effect of Plastic Film Mulching on Growth and Yield of Winter Wheat. The results showed that the water content of topsoil in plastic film mulching stage was significantly higher than that in non-mulched plastic film mulching stage. Mulching significantly increased the plant height, spike length, spikelet number and spikelet number of winter wheat and significantly decreased the number of spikelets The yield of plastic film mulching increased by 45% and 21% compared with non-mulching mulch, respectively. The economic benefit of mulching was obviously higher than that of non-mulching mulching Good application prospects.
