不同浓度NaCl对甜菜生长的影响

Effect of NaCl Different Concentrations on Sugarbeet Growth

研究了营养液中不同盐度(2～280mmol/L)对甜菜生长状况的影响,结果表明,NaCl浓度低于10mmol/L,对甜菜的各生长指标没有明显影响;而NaCl浓度在50mmol/L左右比较适合甜菜生长;超过100mmol/L的高浓度NaCl对甜菜的生长有胁迫作用,浓度越高胁迫作用越强。营养液中盐浓度在280mmol/L以内对甜菜光合作用影响不显著。

The effect of 2-280 mmol/L NaCI concentrations The results showed that there were no obvious effects on su concentrations; but it can make some concentration; 100 mmol/L NaCI or concentration, the greater influence to no obvious effects on photosynthesis of in Nutrition liquid on sugarbeet growth was studied. garbeet growth in accelerating growth and development to more concentrations affect the growth the range of 0-10 mmol/L NaCl sugarbeet about 50 mmol/L NaCl of sugarbeet, the higher NaCl sugarbeet. In the range of 2-280 mmol/L NaCl concentrations, there were sugarbeet.
