Coastal saline-alkali soil greening system based on landscaping waste utilization
The invention discloses a coastal saline-alkali soil greening system and method based on landscaping waste utilization. The coastal saline-alkali soil greening system comprises a covering layer, a to-be-improved soil layer, a permeable film layer, a spraying isolation layer, a concealed pipe salt drainage ditch, a salt drainage well, vent holes, a waterproof layer and a saline-alkali soil layer which are sequentially arranged from top to bottom; the covering layer is arranged on the earth surface near the roots of soil body plants; the to-be-improved soil layer is a mixture of undisturbed saline soil, decomposed landscaping branch and leaf crushed materials and other organic and inorganic fertilizers; the spraying isolation layer is made of garden branch, trunk or tree root waste crushed materials; and the concealed pipe salt discharging ditch is positioned below the spraying isolation layer. According to the system and the method, organic matter resources such as regional landscaping waste can be fully utilized, the salt leaching and discharging efficiency is enhanced, the underground water level is effectively reduced, salt return is prevented, surface evaporation is reduced, the soil fertility is increased, and the purpose of improving salinized soil is achieved. The damage to cultivated land resources can be reduced, the use of building material resources such as stone chips is saved, and the resource utilization of landscaping wastes is realized.
本发明公开了一种基于园林废弃物利用的滨海盐碱地绿化系统及方法，包括从上到下依次设置的覆盖层、待改良土层、透水膜层、隔淋层、暗管排盐沟、排盐井、通气孔、防水层和盐碱土层；所述覆盖层设置在土体植物根部附近地表；所述待改良土层为原状盐渍土与腐熟的园林绿化树枝树叶粉碎料以及其他有机无机肥料的拌和物；所述隔淋层为园林树枝、树干或树根废弃物粉碎料；所述暗管排盐沟位于隔淋层下。本发明该系统及方法不仅可以充分利用区域园林绿化废弃物等有机质资源，强化洗盐排盐效率，有效降低地下水位，防止返盐，减少地表蒸发，增加土壤肥力，实现盐渍土壤改良的目的。还可减少对耕地资源的破坏，节约石屑等建筑材料资源的使用，实现园林绿化废弃物资源化利用。
