棉花地膜覆盖栽培仍有潜力可挖,稍加改变栽培形式,产量产值将大幅度上升。近年地膜覆盖向小拱棚发展。竹皮小拱棚因投资大、用工多,棉农不易接受,如将平播改为深沟下种覆膜代替竹皮拱棚,即成三埂深沟大垄双行地膜栽培。它与原地膜栽培形式不同,仅垄顶形成双沟三埂,埂代替拱棚支架,埂上覆膜呈双沟式拱棚,比竹皮子拱棚省工、省钱、操作方便,棉农易接受。 Cotton mulching cultivation still has the potential to dig, slightly change the cultivation form, output value will increase significantly. In recent years, plastic film coverage to the small Shed development. Bamboo small Shed due to large investment, labor and more difficult for farmers to accept, such as the flatcast into a deep groove under the film instead of bamboo Shed, that is, a three-furrow ditch big ridge double line of plastic film cultivation. It is different from the original form of film cultivation. Only the top of the ridge forms the double furrows and the third ridge, instead of the arch support. The upper cover is double-furrowed, which saves labor and saves money compared with the bamboo skin.
