四翅滨藜吸盐效果分析

Analyse of effect absorb salt from soil about atriplex cancscens

河北有20.0hm2万到33.3万hm2不能利用的盐碱地,为有效改良盐碱地,为后续利用作准备。在详细调查、分析的基础上,科技人员从2010年开始对四翅滨藜进行引种栽植,并进行了四翅滨藜的育苗试验,均取得了成功。栽植四翅滨藜后,在1m深土体内,植株收获带走的盐量为2059.5kg/hm2,土壤脱盐率为9.6%,土壤得到改善,土地生产力得到极大提高。到2013年,四翅滨藜在河北省东部平原盐碱化比较严重的衡水、沧州两地推广应用了7.00hm2,发挥了较好的水土保持生态效益和社会、经济效益。

There is alkaline land 20×10 5 hm 2 to 33.3×10 5 hm 2 in Hebei Province can′t be uses,in order to improve the alkaline land,prepare for use it in future.Base on the details investigation and analysis,from 2010,scientists and engineers import and plant Atriplex cancscens,and culture of seeding,the two work both succeed.After plant Atriplex cancscens,Plants take away salt 2059.5kg/hm 2 in 1m soil.The efficiency is 9.6%that salt get out of soil,improve the soil,and increase the productive of the soil.To 2013,Atriplex cancscens extend and plant over 7.0 hm 2 in the relatively alkaline land of Cangzhou City and Hengshui City,which lies in east of Hebei Province,it bring into play benefit of ecology conservation of water and soil,and society,and economy.
