摘　　要：针对北方干旱坡地雨水存储差、养分贫瘠、耕层浅、作物易倒伏等问题,通过分析国内外土壤改良方法,以河北省干旱半干旱地区为代表,对其典型地块的土壤养分进行丰缺状况调查,提出了机械化土壤改良技术并确定了技术路线,同时设计了悬挂式土壤改良机械。Aimming at the problems of poor rainwater storage,poor nutrients,shallow cropping,and easy lodging of crops on arid sloping areas in the north,this paper analyzed soil improvement methods at home and abroad,and made a careful investigation and study on the abundance and deficiency situation about the soil nutrients of typical plots,taking the arid and semi-arid regions of Hebei Province as a representative.At the same time,the mechanized soil improvement technology was proposed,the technical road-map was established and a suspended soil improvement machine was designed.

关 键 词：干旱地区 抗倒伏 机械化 土壤改良
