Our study showed that N form played a significant role in the overall performance of P. edulis seedlings, followed by the effect of N and K⁺ concentrations. Among the N forms, NH₄ ⁺ significantly improved the growth of P. edulis seedlings compared with NO₃ ^-. Seedling height, leaf number, chlorophyll SPAD value, biomass, and root system architecture (root length, root surface area, root volume, and root tips) were greater with 8 mmol/L of NH₄ ⁺ treatments than with 32 mmol/L of NH₄ ⁺treatments, whereas root diameter and N content of P. edulis seedlings were higher with 32 mmol/L of NH₄ ⁺ than with 8 mmol/L of NH₄ ⁺. K displayed inconsistent effects on the growth of P. edulis seedlings. Specifically, seedling height, leaf number, biomass and root volume increased when the K⁺ concentration was increased from 0 to 0.5 mmol/L, followed by a decrease when the K⁺ concentration was further increased from 0.5 to 3 mmol/L. Root average diameter of the seedlings was the highest with a K⁺ concentration of 1.5 mmol/L, and K had some inhibitory effects on the chlorophyll SPAD value of the seedlings. P. edulis seedlings performed well with 8 mmol/L NH₄ ⁺and further tolerated a higher concentration of both NH₄ ⁺ and NO₃ ^-, although excessive N could inhibit seedling growth. A lower concertation of K (≤ 0.5 mmol/L) promoted seedling growth and increasing K⁺ concentration in the nutrient solution did not alleviate the inhibitory effect of high N on the growth of P. edulis seedlings. Therefore, NH₄ ⁺nitrogen as the main form of N fertilizer, together with a low concertation of K⁺, should be supplied in the cultivation and nutrient management practices of moso bamboo.
