滨海泥质盐碱地基盘造林法研究

盐碱地造林是世界性的难题。采用盐碱地基盘造林法——大穴客土基盘和种基盘造林法在盐碱地进行试验造林,并通过桑苗和种基盘树种的成活率和生长量,种基盘配方配比等对盐碱地基盘造林法进行了系统的研究。结果表明,相对于盐碱地常规造林方法,采用盐碱地基盘造林法下的桑苗的成活率高达98%,平均生长量提高了13.30 cm。种基盘树种的成活率提高52.27%,平均生长量提高9.70 cm;不同盐碱地基盘造林法对种基盘树种的成活率和生长量也影响较大,其中主要体现在种基盘配方中,复合肥的适量添加对植物的成活率和生长量均有显著影响。土壤防蚀剂的添加量对植物生长影响不大,但具有维持基盘形状的作用;在选用的耐盐树种中,国槐较其它耐盐树种更适宜滨海泥质盐碱地。

Afforestation on the Base in Coastal Argillaceous Saline-alkali Land

Afforestation in saline-alkali land is a worldwide challerge.In this article,the afforestation of base in saline-alkali which contains the big cave Soil-bade and Seed-base is used in saline-alkali land.And this article take systematic research of the Seed-base afforestation in saline-alkali land by different matrix ratio of seed-base and the survival rate and growth of the Morus alba and tree species.Results showed that,compared to conventional reforestation methods,the survival rate as high as 98% and the ...
