摘要
由于甘肃省中西部大面积耕地不同程度沙化,严重影响作物生长和该区农业发展。通过近几年对沙化土壤改良剂配方、施用量、施用时间和方法等进行多年试验、示范并反复验证,研究提出了甘肃中西部灌区沙化土地改良技术,为了提高该技术的应用效果,从技术范围,规范性引用文件,术语定义,沙化土地改良技术的选地、整地平地、改良剂施用、施肥翻耕、第1茬作物选择、播种、田间管理、轮作模式、收获和改良效果等方面规范了甘肃中西部灌区沙化土地改良技术,以期为甘肃省及我国西北灌区的沙化地改良种植提供了科学依据,促进甘肃省乃至全国沙化地生态修复。
Due to the large areas of desertification of cultivated land in diverse degree in Midwest Gansu,crop growth and agricultural development in this region have been affected to a great extent.Through years of experimentation,demonstration,and repeated validation on the formula,application rate,application time,and method of desertification soil modifiers,the technology for improving desertification land in the central and western irrigation areas of Gansu has been proposed.In order to improve the application effect of this technology,scope of application,normative documents,terms and definations,and desertification land improvement technology including selection of land,land preparation,application of modifier,fertilization and tillage,first crop selection,sowing,field management,rotation mode,harvest and improvement effect were standardized in this paper.The aim was to provide a scientific basis for the improvement and planting of desertified land in Gansu Province and northwest China,and to promote the ecological restoration of desertified land in Gansu Province and nation wide.
