摘　　要：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 in saline-alkali land is a worldwide challerge. In this article, the afforeatation 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 average growth increased by 13.30 cm of the Morus alba and the survival rate and the average growth iacreased by 52.27% and 9.70 cm of the seed-base which is used the afforestation of base in saline-alkali; The survival rate and the average growth have larger effect by the different afforestation of base in saline-alkali, in which mainly reflected by the formula of Seed-base, the addition of fertilizer has obvious effect and the dosage of preventing soil from erosion has no effect on the survival rate and growth of plants, but the latter is helpful to maintain the form bf Seed-base. Sophora japonica Linn is more appropriate than other species in experiment plot.
