Study on the vitro propagation technology of Alhagi sparsifolia root

We studied the effect of different treatments on the emergence in vitro propagation of Alhagi sparsifolia root segment in the southern fringe of the Taklimakan Desert. The purpose of this study was to provide a new A. sparsifolia vegetation restoration technology. We compared the emergence under three-factors (three kinds of root length, three kinds of planting depth and five kinds of irrigation treatments) fully interactive treatments. The results showed that if keeping the other two factors unchanged the emergence rate was reduced with root length increase, the emergence rate achieve the highest at 10 cm root length. The emergence rate increased with planting depth increasing. Emergence rate reached the highest with planting depth of 30 cm. Emergence rate reach the highest under irrigation regime of 10 m3·m-2 and once on July 30. In addition to the interaction between irrigation treatments and planting depth, there were significant differences among all interactive processing among three factors. In conclusion, 10 cm root length, 30 cm planting depth, 10 m3·m-2 (once) irrigation treatment are the optimal planting pattern.
