塔里木盆地干旱灌区的地膜冬小麦研究

A Study on the Winter Wheat Covered with Plastic Film in Dry Irrigated Areas in Talimu Basin

１９９６年～１９９８年度在塔里木盆地干旱灌区进行冬小麦地膜覆盖栽培试验，结果表明具有显著的增产、节水效果和较好的经济效益，需要加快发展。在干旱灌区独特的生态环境下地膜穴播栽培，适播和晚播均较同期露地播种增产，随播期推迟增产幅度上升，可使晚茬赶正茬。冬小麦适宜选用多穗型品种。

The cultivation experiments on winter wheat with plastic film covering were conducted in dry irrigated areas of Talimu Basin in 1996～1998. The experimental achievements indicate that the method had significant results in both yield increasing and water saving,and brought about good economic benefits,and so it should be popularized at even higher speed.Under the unique ecological environment in dry irrigated area, bunch planting covered with film in both normal and delayed time provided higher production than that of bare sowing. And with the planting time further delayed, yield increasing scale rose sharply, thus making the delayed sowing catch up with the normal sowing. The multiple ear varieties of winter wheat are recommended when using this method.
