Abstract: To explore the effects of different intercropping species on growth, nutrition absorption, and fruit quality of oriental melon, we examined plant height, stem diameter, root activity, contents of mineral elements (N, P, K, Ca and Mg), and fruit quality and yield of oriental melon under the oriental melon monoculture (MM), intercropping of fennel/oriental melon (FM), tillered-onion/oriental melon (TM), or wormwood/oriental melon (WM). Results showed that plant height of intercropping treatments was significantly higher than that of the monoculture over time. The stem diameter of the FM and TM treatments was significantly higher than that of the MM treatment, while there was no significant difference between the WM and MM treatments. At the stretch tendril stage, fruit setting stage, and fruit expanding stage, root activity of FM treatment was significantly higher than that of MM and TM treatments. The mine-ral elements contents of oriental melon plants in three intercropping treatments were higher than that in MM treatment in different degrees, with the mine-ral elements contents of FM treatment being higher than that of TM and WM treatments. The single fruit weights of FM and TM treatments did not differ from the MM treatment. The fruit quality indices of FM treatment were not lower than MM treatment, while some fruit quality indices (including the contents of glucose, fructose, and sucrose) of WM and TM treatments were lower than that under MM treatment. In summary, fennel was a suitable species for intercropping with the oriental melon.
