针对唐山沿海滩涂土壤盐渍化现状,采用“一带一沟挑台造林模式”对欧美107杨进行造林试验研究,种植穴采用客土、粉煤灰/盐碱土(3∶1)两种措施处理。结果显示,经这两种处理,造林成活率可达到97%,从叶绿素含量来看,粉煤灰/盐碱土(3∶1)处理叶绿素含量略高于客土。
According to the status quo of soil salinization in coastal tidal flats in Tangshan, the afforestation experiment was conducted on 107 poplars in Europe and America by using “One Belt and One Gathering Terrace Afforestation Model” Measures to deal with. The results showed that after these two treatments, the survival rate of afforestation could reach 97%. From the perspective of chlorophyll content, the chlorophyll content of fly ash / saline-alkali soil (3:1) was slightly higher than that of the control.
