The influence of the ions of iron ion, Ca2 +, Mg2+, salt content, B3 + and Al3 + on fracturing fluid are tested・ The experiment showed that due to the low concentration of Mg2 +, Al3 + can be ignored by the small effects. When the main affecting ions of iron ion, Ca2 +, salt content, B3 + was removed, the fracturing fluid system can withstand temperature up to 130 °C, the lowest viscosity up to 83 mPa • s after 2 h shearing and the filtration coefficient is 6 ・ 54 X 10 4 m/min12. The damage rate tests show that the maximum damage rate is 21. 16%, when salt water and kerosene are used as mobile media, the viscosity and surface tension of gel breaking liquid are 3・ 75 mPa • s and 22. 7 mN/m respectively, which meet the requirements of application indexes.

One-year-old Broussonetia papyrifera seedlings were subjected to 0.4,1,2,3, and 4 g·kg-1 of soil NaCl stress, and their biomass accumulation, leaf plasma membrane permeability, and the absorption, allocation and translocation of K+, Ca2+, Na+, and Cl-, as well as the symptoms of salt injury, were studied and investigated. The leaf plasma membrane permeability increased with the increase of soil NaCl concentration and of the duration of soil NaCl stress, and the seedling's root/shoot ratio also increased with increasing soil NaCl concentration. When the soil NaCl concentration exceeded 3 g·kg-1, leaf plasma membrane permeability and seedling's biomass accumulation were affected significantly. The Na+ and Cl- concentrations in different organs of seedlings increased with increasing soil NaCl concentration while the K+ and Ca2+ concentrations were in adverse, and the ion contents in leaves were always much higher than those in other organs, illustrating that soil NaCl stress affected the K+ and Ca2+ absorbing capability of roots, and inhibited the selective translocation of K+ and Ca2+ to aboveground parts. As a result, the K+ and Ca2+ concentrations in leaves and stems decreased. The study showed that B. papyrifera could effectively resist the injury of osmotic stress from soil salt via absorbing and accumulating Na+ and Cl-, but excessive accumulation of Na+ and Cl- could induce salt toxicity. As a non-halophyte species with relatively strong salt resistance, the aboveground parts of B. papyrifera did not have significant salt-exclusion effect. [ABSTRACT FROM AUTHOR]

In this paper, a pot experiment using quartz sands was conducted to study the effects of different concentrations of NaCl (0, 25, 50, 75, 100 mmol·L⁻¹) on the ion absorption, distribution and essential oil components of flowering Schizonepeta tenuifolia. The results showed that as NaCl concentration increased, Na⁺ content of root, stem, leaf and flower increased significantly, and that of the aerial parts was in a higher level than in the root. Regarding the K⁺ content, it decreased in the root but increased in stem, leaf and flower. Some changes were detected in the Ca²⁺ content, but not significant on the whole. The value of K⁺/Na⁺ and Ca²⁺/Na⁺ reduced as a result of increasing NaCl concentrations. The content of essential oil increased under medium salt treatment (50 mmol·L⁻¹ NaCl). However, the synthesis and accumulation of essential oil was inhibited by the serious salt treatment (100 mmol·L⁻¹ NaCl). Over 98% of the essential oil components were terpenes, in which pulegone and menthone were the most two abundant compounds. Varieties of essential oil components did not change significantly under salt stress but their relative proportions did. The transformation of pulegone to menthone was enhanced and the value of pulegone/menthone based on their relative contents decreased with NaCl concentration increasing. Consequently, menthone ranked the most abundant compound by replacing pulegone. Relative content of D-limonene increased under medium and serious salt stress, and that of β-caryophyllene only increased under mild treatments. So our research could provide references for the standard cultivation on saline soil of S. tenuifolia., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Chinese Pharmaceutical Association.)

In order to explore the adaptive capacity of Alhagi sparsifolia to soil salinity (mild, mo-derate, severe saline soil), the distribution, adsorption and translocation characteristics of Na + , K + , Ca 2+ , Mg 2+ in different organs of A. sparsifolia, which is a dominant native vegetation in southern edge of Tarim basin, were investigated. The results showed that when grown on a mild and moderate saline soil, Na + distribution in different organs of A. sparsifolia followed the order of stem≈thorn>leaf>root; when grown on a severe saline soil, Na + distribution followed leaf>stem≈thorn>root. The distribution of Ca 2+ and Mg 2+ followed leaf >thorn>stem>root. With the increase of soil salt level, Na + content in different organs of A. sparsifolia increased, while K + content in leave decreased; meanwhile the increasing soil salt level significantly decreased the K + /Na + ratio in both root and leave, as well as the Ca 2+ /Na + and Mg 2+ /Na + ratios in all organs. The selective transportation coefficients for Ca 2+ -Na + and Mg 2+ -Na + followed order of stem-leaf>stem-thorn>root-stem under saline habitats. Based on the integrated analysis, in order to adapt to salinity habitat, A. sparsifolia could use multiple organs to accumulate Na + , depending on soil salt level. Na + could accumulate in stem and thorn at a relative low level, but in leaves at high levels. Besides, Ca 2+ and Mg 2+ could be the inorganic osmotic adjustment substances for A. sparsifolia to adapt the saline environment.
