冬小麦全生育期覆膜是近年发展起来的一种新的栽培技术。该技术采用冬小麦穴播方式，自播种至收割的整个生育期内，地膜始终覆盖在地面。根据１９９７ 年１０ 月至１９９８ 年６ 月在东光县龙王李乡进行的灌溉试验，初步确定了冬小麦全生育期覆膜灌溉的适宜灌溉制度，在偏湿润年为：灌３ 次水（ 包括播前水） ；播前水定额根据土壤墒情确定，一般为４５０ ～９００ ｍ ３ ／ｈ ｍ ２ ；起身～拔节期的灌水定额为６００ ｍ ３／ｈ ｍ ２ ；抽穗～灌浆期的灌水定额为４５０ ｍ ３ ／ｈｍ ２ ；总灌溉定额为１５００ ～１９５０ ｍ ３ ／ｈ ｍ ２ ；试验结果表明，与不覆膜的相比，全生育期覆膜冬小麦，节水４１２ ％ ，产量提高２２８ ％ 。
Covering the whole growth period of winter wheat is a new cultivation technique developed in recent years. The technology uses winter wheat planting method, from sowing to harvest the entire growth period, the film has always been covered in the ground. According to the irrigation experiment conducted in Liwang Township, Longwang County, Dongguang County from October 1997 to June 1998, the appropriate irrigation system for film-covered irrigation in the whole growth period of winter wheat was preliminarily determined. In partial wetting years, irrigation was 3 times of water Pre-sowing water quota was determined based on soil moisture, generally 450 ~ 900 m 3 / h m 2; up ~ jointing stage irrigation quota of 600 m 3 / h m 2; heading ~ filling period of irrigation quota 450 m 3 / hm 2. The total irrigation quota was 1500 ~ 1950 m 3 / h m 2. The results showed that compared with the non-mulched mulching, winter wheat was covered with water, saving 41.2% of water and increasing yield by 22%. 8%.
