| description | [Objective] The study aims to investigate the response of C, N, P, and K distribution to water
and nitrogen addition in Xanthoceras sorbifolia seedlings in order to provide references for water-nitrogen
environmental adaptation strategies and high-quality seedling cultivation. [Methods] A two-factor (nitrogen
and water) randomized block design was adopted in this study. Four N fertilization levels [N0:0 g/m2, N1:
5 g/m2, N2:10 g/m2, and N3:15 g/m2] and three levels of water addition [well watered (WCK), drought
(Wd), and fully watered(Ww)] were set up to explore the impact on the ecological stoichiometric characteristics
of X . sorbifolia leaves, branches, and roots. [Results] (1) The C, N, P, and K levels of seedlings
were independently or interactively influenced by nitrogen and water, while the stoichiometric ratios
were mainly affected by nitrogen addition. Under well-watered conditions (WCK), nitrogen addition increased
C, N, and P levels. Under drought conditions (Wd), high nitrogen addition (N3) could resist
drought by increasing K level and decreasing N and P levels. Under well-watered conditions (Ww), only
high nitrogen addition (N3) effectively alleviated nitrogen limitation. (2) C, N, P, and K nutrients were
mainly concentrated in leaves, supporting photosynthesis and vegetative growth. The variability of N and
P contents in leaves was high, but the N/P ratio remained stable. (3) The same element exhibited a high
correlation among different organs, particularly between leaves and roots, maintaining stable growth.
[Conclusion] Nitrogen addition alleviates nitrogen deprivation but increases the demand for P and K. It is
recommended to reduce nitrogen fertilizer application under suitable water condition to reduce pollution and
maintain growth potential. |
