摘要
河北盐碱地面积较大,开发利用不充分,尤其是盐碱地造林发展缓慢。本文通过试验证实沙柳(Salix mongolica Sivzev)具有抗0.3%～0.4%盐碱能力,比旱柳(S.matsudana Koidz)、垂柳(S.babylonica L.)抗盐能力强,是优良高效盐碱地造林树种。并为在盐减地建立柳编基地提供了利学依据,为引种沙柳和开发盐碱地指出了新途径。
There is a large area of saline-alkali soil in Hebei province, it has not been utilized fully, especial for the afforestation.By the means of experiments, it is confirmed that Salix mongolica Sivzev is a good species for afforestation on the soline-alkali soil and its saltresistance concentration is 0.2—0.4%, much better than that of S. matsudana Koidz and S.babalonica L..
This study has also provided a scientific basis for establishing a sier -goods manufacture base and a new way for opening and using saline -alkali soil.
