我省有盐碱地800多万亩,其中滨海盐碱荒地300多万亩.根治海河工程为盐碱地造林创造了条件.滨海盐碱地土壤(0-60厘米)含盐量0.4-1.6%,氯化钠占全盐的80%以上,PH值7.8左右,一般树木不能成活生长.1970年以来,我们在黄铧县赵家堡公社与贫下中农相结合,在含盐量0.6%以上,过去根本不长树或只长一些野生的柽柳的重盐碱地上,开展盐碱地造林科学实验,获得成功.营造了20多华里的海防林带,种植紫穗槐、榆树、刺槐、白
The province has more than 800 million mu of saline-alkali land, of which more than 300 million mu of coastal saline-alkali wasteland.The project of culling the Haihe River has created the conditions for afforestation of saline-alkali land.The salinity of 0.4-1.6% of saline soil (0-60 cm) More than 80% of the whole salt, PH value of 7.8 or so, the general growth of trees can not survive since 1970, we Huangzhu County Zhaojiapu commune and poor middle peasants combined salt content of 0.6% or more in the past did not grow the tree Or just a few wild Tamarix salinization ground to carry out scientific experiments of afforestation in saline-alkali to be successful.Hold more than 20 Huarong shelterbelt, planting Amorpha fruticosa, elm, black locust, white
