摘要:

为探究咸水滴灌对人工种植肉苁蓉寄生体系盐离子分配和肉苁蓉品质的影响,在塔里木盆地塔克拉玛干沙漠边缘,选择4个灌水矿化度差异较大的样地,采集土壤、梭梭和肉苁蓉样品,分析土壤、寄生体系各部分盐离子含量及肉苁蓉主要药用成分含量,结果表明:(1) 在高矿化度咸水滴灌下,接种肉苁蓉的梭梭根部、主茎和同化枝盐离子含量为:同化枝>根>茎,肉苁蓉体内盐离子含量与寄主根系含量相近;(2) 肉苁蓉体内总盐、Na+和Cl-含量均随灌水矿化度的增高而增加;肉苁蓉体内K+占总盐分的1/3,具有较强的吸收富集K+的能力,但K+含量并未随灌水盐浓度的变化而表现出显著性差异;(3) 肉苁蓉体内主要药用成分苯乙醇苷类物质含量随灌溉水矿化度的升高而增加,盐分胁迫有助于刺激肉苁蓉体内主要药用成分的积累。因此,较高矿化度咸水滴灌可以提高肉苁蓉的品质,但需要注意长期高盐胁迫对寄主梭梭的影响,因而制定合理的灌溉制度是不可或缺的。

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.
