摘要
为研究盐碱地种基盘播种造林的成效,对唐山试验地的台田整地、水盐动态变化、不同基盘配方和树种的种基盘生长情况等进行了系统的研究。结果表明:土壤水分和盐分关系密切,土壤表层,盐分和水分变化趋势相同;中深层,盐分与水分变化趋势相反。台田整地后,平均土壤盐分含量逐年下降;种基盘直播造林技术体系在滨海泥质盐碱地上取得初步成效,3a后刺槐、火炬、紫穗槐种基盘成活率达30%左右。客土、草炭、蛭石和珍珠岩的体积比为50∶30∶10∶10的基盘配方的种基盘成活率比其它配方高,说明该配方局部改善植物生长环境的性能强,更适宜树种生长。
The purpose of this paper is to study the effect of seed-base afforestation in saline-alkali land.Preparation of platform field,water-salt dynamic,the survival rate of different seed-base and tree species were investigated in coastal argillaceous saline-alkali land of Tang Shan.Results showed that,there was a close relation between the water content and salt content,in soil surface layer,the trend of soil salt and water was similar while the trend was reverse in middle and deep layers.The average salt of soil decreased year by year by preparation of platform field.The afforestation of seed-base has achieved initial success in saline-alkali land which the three-year survival rate of seed-base reached 30% in Rhus typhina,Locust,Amorpha fruticosa L.The survival rate of seed-base which the volume ratio of new soil,peat,vermiculite and perlite was 50∶30∶10∶10 was better than other seed-base.This seed-base which could improve the properties of plant growth environment was more suitable for tree species.
