沧州市位于华北北部,濒临渤海湾。受季风气候和海水浸渍影响致使土壤盐碱,属滨海海浸盐渍区。市区土壤含盐量0.2-0.4%,pH值8.0左右。以往在这样的立地条件下栽花种树困难很大。沧州市园林管理处经过多年的探索,初步总结了一套在盐碱土上种植花草树木的技术,使沧州的城市园林绿化面貌有了很大改观。现将主要技术方法介绍如下。一、工艺改土栽培1、离袋种植:在盐碱土地上根据植株大小挖种植穴。在穴内放置大小相应的隔离袋,袋内装入非盐碱客土。将花木定植在袋内,填土稍高出地面约3厘 Cangzhou City is located in northern North China, on the verge of the Bohai Bay. Affected by the monsoon climate and seawater soaked soil salinization, is a coastal sea-water salinization area. Urban soil salt content 0.2-0.4%, pH 8.0 or so. In the past, planting flowers under such site conditions is very difficult. Cangzhou City Garden Management Office after years of exploration, initially summed up a set of flowers and trees in saline-alkali soil technology, so that the city of Cangzhou landscape has been greatly improved. Now the main technical methods are described below. First, the process of soil cultivation 1, away from the bag planting: digging planting holes in saline-alkali soil according to plant size. In the cave to place the size of the isolation bag, bag filled with non-saline alkali soil. Will be planted in the bag of flowers, fill the ground slightly higher than about 3%
