中重度碱化土壤生态环境表现为:地表碱斑和草皮相互错落,碱斑面积占50%左右;重度几乎为光板地,草皮所占比例很少。土壤粘重质密,透水性极差,仅有的植被以芨芨草、碱蓬为主,土壤微生物很少。主要理化性质指标是:全盐≤3.0 g/kg,碱化度≥30%,p H≥9.5。因此,其生态恢复主要技术措施是:1、土地整理技术(深耕翻+挖暗沟+平整地):造林前一年秋季就开始深翻晒田,熟化土壤。土壤深翻最 Medium and severe alkalization of soil ecological environment performance as follows: the surface of the spot and the turf patch off each other, alkali spot area accounted for about 50%; severe almost light board, turf accounted for a small proportion. Soil stick heavy quality, very poor water permeability, the only vegetation to Achnatherum, Suaeda mainly small soil microorganisms. The main physical and chemical properties indicators are: full salt ≤ 3.0 g / kg, alkalinity ≥ 30%, p H ≥ 9.5. Therefore, the main technical measures of ecological restoration are as follows: 1. Land consolidation technology (deep tillage + digging ditch and flat land): Deep forest clearing and soil aging will begin in the autumn one year before reforestation. The most deep soil flip
