为解决盐碱地造林困难问题,以垂柳、白柳、河柳、旱柳为亲本,经过10 a的选育,选育出了85—68、85—70、85—96三个优良无性系。其中:85—68在轻度盐碱地上生长良好,且有较强的速生性;85—70、85—96在中度盐碱地上生长良好。
In order to solve the problem of afforestation in saline-alkali soil, three elite clones, 85-68, 85-70 and 85-96, were bred by weeping willow, white willow, heliotrope, and willow. Among them, 85-68 grew well on mild saline soils and had a strong fast-growing rate; 85-70, 85-96 grew well on moderate saline-alkali soil.
