新疆平原地区的土壤大都有不同程度的盐碱化.苏打盐渍土普遍存在,严重地影响了土地利用和建立高产稳产农田.无论是巩固目前已有绿洲、提高作物单产,还是扩大耕地面积,都受到土壤苏打盐渍化的制约,因此,必须改良苏打盐渍土,不断提高土壤肥力.一、苏打盐渍土的形成新疆苏打盐渍土的形成与岩石组成、母质沉积物和积盐阶段有关.1.昆仑山的中央核心带多为花岗岩和片
Most of the soil in the plain of Xinjiang has different degrees of salinization.Sodium salinized soils are ubiquitous and seriously affect the land use and the establishment of high and stable yield farmland.It is necessary to consolidate the current oases, increase crop yields or expand the area of cultivated land, Are subject to soil soda salinization constraints, it is necessary to improve soda saline soil, and continuously improve soil fertility.First, soda saline soil formation Xinjiang soda saline soil formation and rock composition, parent material sediment and salt phase Related 1. The central core belt of the Kunlun Mountains is mostly granite and sheet
