摘要
比较了蒸馏水、自来水和祁连山"七一"冰川的冰川水的pH值、电导率.冰川水的电导率为2.31×10-2s·m-1,为自来水的1/2,与其pH值一样,介于蒸馏水和自来水之间.测定了冰川水的主要矿质元素含量,结果表明,冰川水具有很低的Na+含量及较低的矿化度(101.50mg·L-1).通过种子萌发实验、植物组织培养的脱分化和再分化过程的比较研究,揭示冰川水的水质纯净,完全可以满足植物组织培养的要求,是地球上非常宝贵的优质水资源.
The conductance,pH values, and the concentrations of major ions of glacier water sampled from the Qilian Mountains were measured. A comparison among glacier water, distilled water and tap water was carried out. The conductance of glacier water is 5.22×10^(-2) (s·m^(-1)), which is only half of the tap water sample. The pH value of glacier water is also between the distilled water and tap water. The results showed that the Na^+ concentration of glacier water is very low, and the TDS is only 101.50 mg·L^(-1). Experiments on plant seeds bourgeoning and plant tissue culture indicated that the glacier water is pure enough to be used in plant tissue culture. These show that the glacier is a very valuable and high quality water resource on the earth.
