双垄沟秋季全覆膜技术应用效果分析

Analysis of application effect about the technology of double furrows mulched with plastic film in autumn

宁夏同心县下马关镇南塬村是一个没有外来客水灌溉的村庄,近些年气候干暖化使该地雨养农业面临严峻挑战.通过对该区域农户调研数据与气象数据的分析,从技术、经济和社会3个方面对双垄沟秋覆膜技术在该区域的可接受性进行分析.得出如下结论:双垄沟秋季全覆膜播种技术在技术层面上能够有效改善作物生长条件;在经济层面上能够有效增加粮食产量;在社会层面上符合农民的种植习惯,农民的接受程度较好.

Ningxia is the planting of marginal regions,agriculture is very sensitive to climatic change.The Nanyuan Village is not a foreign guest water irrigation village,the rainfed agriculture faces grim challenge because of the climate drying and warming in this region in recent years.Based on the regional household survey data and meteorological data analysis,we analyzed the acceptability of double furrows mulched with plastic film in autumn in the regions from the technology,economy and society three respects.Draw a conclusion： On the one hand,the technology can effectively improve the conditions of crop growth in technical level and effectively increase grain yield on the economic level,among them,corn production increased by 86%,potato yield increased by 50%,watermelon production increased by 85% and sunflower production increased by 87%.On the other hand,the technology consistent with the farmer cultivate a habit on a social level and the acceptance of the farmer is fairly good.What＇s more,the problem remains to be further studied in the technology using process.
