Phyllostachys praecox is a valuable tree species in karst ecosystems, but improper mulching practices can worsen soil degradation. Understanding nutrient limitations crucial for successful restoration and sustainable development. However, it remains unclear whether how management of affects enzyme stoichiometry limitation areas. Here, we conducted field experiment Chongqing bamboo forest ecosystems with four treatments: 1-year (T1), 2-years (T2), recovery (T3), no (CK). We investigated the activities C-acquiring β-1,4-glucosidase (BG), N-acquiring enzymes L-leucine aminopeptidase (LAP) β-1,4-N-acetylglucosaminidase (BNA), as well P-acquiring phosphatase activity (AP), to assess C, N or P identify main factors influencing microbial limitation. Compared CK treatment, both T2 T3 treatments significantly increased SOC, TN, MBC, MBN. Furthermore, stoichiometric ratio forests deviated from global ecosystem 1:1:1. T1 > presented higher values C/(C + N) P), having that were 1.10 1.12 greater than those T2, respectively. Additionally, there was significant negative correlation between C total nutrients, positive biomass ratios. In conclusion, changes affect their ratios by nutrients This study suggests an alternate year cover pattern (mulching one resting next) scientific approach forests, contributing better understanding mechanisms ecosystems.

This study investigates the dynamics of soil CO2 emissions during cover period Phyllostachys violascens and impact different measures, aiming to provide references for reducing environmental effects bamboo cover. An L27 (913) orthogonal experimental design was employed, setting following variables: (1) heating materials: chicken manure, straw cake, wheat ash; (2) thickness husk layer: 15 cm, 25 35 cm; (3) moisture levels before covering: 10 20 cm. The emission rate showed a unimodal curve, with significant overall increase period. Throughout entire period, average (25.39 μmol·m−2·s−1) 5.1 times higher than that uncovered Lei forest (5.02 same Thicker layers (25 cm cm) corresponded rates, differences noted among thicknesses. When moist highest (62.51 μmol·m−2·s−1); resulted in significantly lower rates. Chicken manure produced peak third week, at 70.64 μmol·m−2·s−1, while cake ash reached their peaks fifth 66.56 μmol·m−2·s−1 57.58 respectively. interactions between three factors (heating materials, layer thickness, levels) affected By optimally configuring these factors, can be regulated. recommends using or as combined moistening covering. approach effectively reduces total ensuring suitable temperatures growth shoots spring. research provides scientific basis management forests, aiding optimization covering measures achieve low-carbon sustainable management.
