The growth and nutrients uptake of Zamioculcas zamiifolia in still hydroponics

Four formulae of nutrient solution were used to plant Zamioculcas zamiifolia in still hydroponics. The results showed that all growth indices of Zamioculcas zamiifolia in still hydroponics were near to or better than those in medium culture. The pH value of nutrient solution dropped and the EC value increasd, while the growth of Zamioculcas zamiifolia was not affected. Water consumption, total uptake of N, P and K and nutrient efficiency were the highest in formula 4. Therefore, Zamioculcas zamiifolia is adaptable to still hydroponics and formula 4 is the best among the formulae tested. In addition, the growth rate and absorption rate of water and nutrients by Zamioculcas zamiifolia were different during different periods.
