摘要
以唐山市滨海地区重盐碱地为研究对象,以南堡盐场为试验地,采用营养客土基盘技术,以及不同的整地技术,进行桑树苗造林试验。结果表明:在台田上采用营养客土基盘具有阻隔盐碱的作用,桑树苗成活率明显高于对照苗,大部分桑树苗能够成活,说明营养客土基盘具有良好的改土阻盐效果,能够为树木正常生长创造良好的小生境条件,有利于提高造林成活率,促进林木生长;采用隔离式客土基盘阻盐等综合技术,在渤海湾重盐碱地进行造林是可行的。研究结果可为唐山地区重盐碱地造林提供改土阻盐技术支持,从而有利于推动重盐碱地的造林工作。
Coastal saline land in Tangshan City was taken as the research object,and some experiments were carried out in Nanbao salt field.Seed-base technique and some measures of site preparation were applied to test the survival rate and growing state of Morus alba Linn seedling when planting in serious saline soils.Results indicated that the seed-base technique performed better effects on improving soil and cutting off the salt flow.After the seed-base technique was employed,most of the seedlings survived and grew well in heavy saline soils compared to the control.This experiment implies that the seed-base technique could create better growing environment for Morus alba Linn seedlings,which will increase survival rate and improve trees growing.It can be concluded that the integrated technique is effective and practical in serious coastal saline land in gulf of Bohai Sea,which will offer afforestation technique for Tangshan City and advance the afforestation development in heavy saline soils.
