唐山市丰南区沙河口土壤改良与绿化技术研究

Soil Improvement and Greening Technology Research in Shahekou,Fengnan Region,Tangshan City

为了研究唐山市丰南区沙河口土壤改良和绿化技术,2014年开展了耐盐植物的选取、土壤改良、苗木的栽植和管护等工作。共选取了5种植物:竹柳、白蜡、芙蓉葵、紫穗槐和费菜。土壤改良的工作手段包括深翻、添加土壤改良剂、下盲管、大水浇灌等,改良的主要目的为降低土壤盐度、增加土壤松散度、增加土壤肥力。2014年5月初开展了种植试验,苗木经过一个多月的管护,成活率达到了80%以上。该研究为有效推广北方沿海地区盐碱地的绿化起到了积极的推进作用。

In order to study soil improvement and greening technology in Shabekou, Fengnan Region, Tangshan City, the selection of salt-tol- erant plants, soil improvement, seedling planting and management work was carried out in 2014. Total 5 kinds of plants： bamboo willow, white wax, lotus kwai, Sedum aizoon and Sedum aizoon were selected; Soil improvement through the soil, including deep digging, add soil conditioner, put blind pipe, water irrigation, etc, the main purpose of the improvement include soil salinity reducing, increasing soil loose de- gree, increasing soil fertility. The experiments in May 2014 were conducted, after more than a month of the management of the seedling and survival rate reached over 80%. The study plays a positive role in promoting saline-alkali land greening in northern coastal areas.
