Abstract:

The impact of saltwater drip irrigation on salt ion distribution and the quality of Cistanche cistanche Ma and Haloxylon ammodendron-Cistanche deserticola Ma (H-C) association during artificial cultivation in the planting base of C. deserticola on the Taklimakan Desert edge was examined. We selected four sample plots with obvious differences in irrigation mineralization to collect samples of H. ammodendron and C. deserticola. We also collected and analyzed the salt ion content in soil, H-C association, and main medicinal components of C. deserticola from different locations. Results showed the following: (1) The salt content of roots, main stems, and assimilated branches of C. deserticola inoculated by drip irrigation with high salinity brackish water was in the order of assimilating branch>coarse roots>fine roots>stems; the salt content in C. deserticolais was similar to that of the root system. (2) The contents of total salt, Na+, and Cl- in C. deserticola increased with an increase of irrigation salinity and soil salinity; the proportion of K+ in C. deserticola accounts for one-third of the total salt and can accumulate K+, but there is no significant difference in K+ content with irrigation salt concentration. (3) The synthesis of phenylethanol glycosides, which are the main medicinal ingredient in C. deserticola, increased with an increase of irrigation salinity, and salt stress promotes the accumulation of a main pharmacological component in C. deserticola. In consequence, high salinity saline water drip irrigation can improve the quality of C. deserticola. And it is necessary to pay attention to the effect of long-term high salinity stress on the host H.ammodendron, so it is important to develop a reasonable irrigation system.

Key words: drip irrigation with saline water, Cistanche deserticola Ma, salt ions, officinal quality
