The functional mechanism of deep sea water and the high-quality plant production by structural control of the water

为探讨深海水营养液的结构调控方法，采用NFT培养方法，研究了深海水营养液的理化性质及其对根系物质吸收的影响。在本实验中，进行了TSDC分析（热刺激去极化电流法），并进行了定性评价的结构的稀释水与极少量的阳离子和电解质溶液。用深海水营养液培养NFT的结果是，营养液（EC：10.0dSm ~（2+））的渗透势<-1>降低，粘度增加，根系对营养液的吸收受到抑制。在根系对阳离子的吸收方面，与对照相比，深海营养液中Ca^2+和K^+的吸收速率较低。TSDC曲线表明，Ca^2+和K^+浓度较高的水使A峰向高温移动，这意味着水分子的排列比纯水更有序。由TSDC估计的A峰的轮廓可以被认为是表征水分子的运动。

In order to investigate the structural control method for the nutrient solution added deep sea water, physical and chemical properties of the deep sea water nutrient solution and its effects on the material absorption in root were examined in NFT culture. In this experiment, TSDC analysis (thermally stimulated depolarization current method) was performed, and the qualitative evaluation for the structure of dilution water with very small amount of cations and electrolyte solution has been carried out. As the results of NFT culture using the deep sea water nutrient solution, the osmotic potential of the nutrient solution (EC:10.0 dSm^<-1>) lowered, the viscosity increased, and the absorption of the nutrient solution in root was restraint. As for the absorption of cations in root, the absorption rates of Ca^<2+> and K^+ in the deep sea water nutrient solution were low as compared with the control. TSDC profiles showed that the water with higher concentration of Ca^<2+> and K^+ shifted A peak to higher temperature, this means that the water molecules would be more orderly arranged compared with that of pure water. The profile of A peak estimated by TSDC could be recognized that the movement of water molecules would be characterized.
