摘　　要：宁夏海原地区位于干旱地带,谷子是当地主要种植的粮食作物之一,当前谷子种植面临水资源不足等问题。因此,有必要探索地膜覆盖栽培技术对谷子生长发育及产量的影响。本研究通过对海原地区张杂谷13号谷子进行3种不同类型地膜(渗水地膜、生物降解膜和全降解生物智能地膜)、2种不同覆盖方式(半膜覆盖、全膜覆盖)处理,研究了不同栽培方式对谷子生长发育、形态特征和产量的影响。结果表明,采用常规地膜全膜覆盖栽培方式的谷子根系发育快,植株生长健壮,产量显著高于其他栽培方式。因此,宁夏海原地区谷子采用常规地膜全膜覆盖栽培后增产明显,经济效益高,可大面积推广应用。The Haiyuan region of Ningxia is located in an arid area,and millet is one of the main grain crops grown locally.Currently,millet cultivation faces problems such as insufficient water resources.Therefore,it is necessary to explore the effects of plastic film mulching cultivation techniques on the growth,development and yield of millet.This study investigated the effects of different cultivation methods on the growth and development,morphological characteristics and yield of Zhangzagu No.13 millet in the Haiyuan region of Ningxia,by treating it with three different types of plastic film(permeable plastic film,biodegradable plastic film and fully degradable bio-intelligent plastic film)and two different covering methods(half-mulching and full-mulching).The results showed that the conventional plastic film full-mulching cultivation method led to faster root development,robust plant growth,and significantly higher yield of millet compared with other methods.Therefore,the conventional plastic film mulching cultivation of millet in Haiyuan region of Ningxia has significant yield increase,high economic benefits,and can be widely promoted and applied.
