Abstract:: The cultivars of Maranta arundinacea L. was used as material，a total of seven treatments pot cultivation and laboratory analysis methods were studied，using pot experiment and laboratory analysis to study the impact on the growth and nutrient absorption of Maranta arundinacea L.，under the condition of different nutrient solution pH.The results showed that in the tap-water supply，solid acid pH nutrient solution formulation plants could grow normally.Compared with CK，not only all of the solid acid-treated leaf area was no difference，but also plant height was not significantly different，except the treatments of N1+SPA1 and N2+SPA2，also the chlorophyll content were not reduced at least.The results also showed that in all the solid acid treatments，compared with CK,Mo，Zn content of the highest N3+ASA3 and N3+SPA3 teatments plants still significantly decreased 46.50%，23.13%.Even if the treatment N3+SPA3 plant Mo accumulation was the highest in all solid acid treatment，but it was significantly reduced 45.09%.In summary，this study selected treatment N3+SPA3 as the optimum nutrient concentration，solid phosphoric acid as the adjustment agent.
