摘要: 选取玉米为研究对象,以甘肃省典型的干旱区环县为研究区域并划定评价单元,以覆膜和不覆膜为对比,采用玉米适宜性指数法,通过确定玉米适宜性评价层次模型和评价指标及其隶属度,评价玉米种植适宜区。结果可知:全膜双垄沟播玉米栽培技术较传统露地种植有效保持了土壤墒情和养分,提高了土壤含水量和有效积温,大幅增加了玉米高度适宜性种植区域,增产效果明显,较常规种植高度适宜区面积增加了51368.57 hm2,增加了25.81%。适宜区面积减少了21566.2 hm2,减少10.82%;勉强适宜区面积减少了16975.1 hm2,减少8.53%;不适宜区面积减少了12827.2 hm2,减少6.45%。

Abstract: The authors selected maize as the research object and took Huanxian—a typical arid area in Gansu Province as the study area, compared film mulching with no film mulching (as the control), adopted maize suitability index method, evaluated maize suitable planting area based on determination of hierarchical evaluation model of maize suitability and evaluation index and the membership degree. The results showed that the fully covered double furrow sowing cultivation could effectively maintain soil moisture and nutrients compared with traditional open field cultivation, improved soil moisture content and the effective accumulated temperature, significantly increased the high suitable planting area for maize, and had obvious yield increasing effect. The high suitable planting area increased by 51368.57 hm2 (25.81%) compared with that of conventional cultivation. The suitable planting area decreased by 21566.2 hm2 (10.82%), the barely suitable planting area decreased by 16975.1 hm2 (8.53%) and the unsuitable planting area reduced by 12827.2 hm2 (6.45%).
