摘要
试验地选择在营口国道庄林线大水塘至收费口段,采用垫层加隔离层的复合栽培方法。复合栽植措施由10cm厚炉灰渣垂直底部垫层来阻断土壤中毛细管导盐,20cm厚客土垂直垫层作为植被根系缓层,此外在坡度为1/1.5斜坡上架设木塑结合隔离板构成。结果表明,该措施效果较好。
Due to the high salt content and high hardness index of salt pond base soil on the side ditch of both sides of Zhuanglin Road shoulder, the soil salinity of highway shoulder was relatively high. Thus, special measures must be taken in order to plant trees while guarantee a higher survival rate in such special environment. The experiment was carried out in the section from Zhuanglin Road Big Pond to feecharging station on the highway where the compound cultivating method adding insulting layers to pad layers was adopted. The compound measure was composed of blocking the capillary vessels in soil by vertically paving I0 cm thick ashes layer, paving 20 cm thick Guest earth vertically as the amortized layer for vegetation root, as well as erecting plywood insulating board on the slope of 1/1.5. The result indicated that this kind of measure was effective.
