Abstract: One-year-old Ficus microcarpa cuttings were used as experimental subjects, and the effects of different physiological and biochemical indexes on F.microcarpa under different water and salt stress were studied by using a completely randomized experimental design. The results show that single salt stress (salt concentration of 2.5‰) had the smallest MDA (malondialdehyde) content but 31.40% higher than the control group, the activity of SOD (superoxide dismutase) of single water stress was the highest but it was 31.93% lower than that of the control group, single salt stress (salt concentration 7.5‰) had the highest CAT (catalase) activity but 6.65% higher than the control group, single salt stress (salt concentration of 2.5‰) had the highest POD (peroxidase) activity but was 9.24% lower than the control group, single salt stress (salt concentration of 5‰) had the highest soluble protein content but 10.29% lower than the control group, the proline content of single salt stress (salt concentration of 5‰) was the largest and 0.30% higher than the control group; In the stress test group, the single salt stress treatment had less effect on F.microcarpa and the single salt stress with the salt concentration of 2.5‰ had the strongest stress resistance. In summary, it shows that F. microcarpa has certain water and salt tolerance, and it is suitable as a landscaping shelter forest tree species in coastal areas of Fuzhou.
