From the perspective of the nutrient cycle, it was proved that SC could recover to the level of CK after 5 years. Conclusion Five years after cutting, nitrogen, phosphorus, and potassium nutrient storage reached the level of the pre-cutting and CK. With the restoration of the plots, the utilization coefficient of each nutrient gradually decreased, and there was no difference with CK Cutting had no significant effect on the cycling coefficients of N, P and K. (4) Strip cutting significantly increased the utilization coefficients of N, P ( P < 0.05). (3) Five years after cutting, the retention of nitrogen in RB was less than that in SC and CK There was no significant difference in the amount of N, P and K returned and nutrient storage between the SC and CK. ![]() The return of nitrogen in SC was decreased (2) Three years after cutting, the retention of N, P, and K in the RB was less than that in the SC and CK The return of nitrogen in SC and RB was significantly lower than that in CK. Result (1) In the first year after cutting, there was no significant difference in the retention of N, P, and K among different treatment plots. The characteristics of nutrient flow and cycling were compared among different treatment plots. Therefore, nutrient flux was quantified, and the nutrient cycling coefficient of the moso bamboo forest was calculated. The biomass of moso bamboo, understory vegetation, litter yield, and corresponding nutrient contents of each component was investigated for five years after cutting. Method We selected the plots that strip cut with 8 m width (SC) and its reserved belts (RB) as the research object and the traditional management forest (CK) as control. Abstract: Objective To study the dynamics of nitrogen (N), phosphorus (P), and potassium (K) nutrients in moso bamboo forest after strip cut, so as to provide a scientific basis for nutrient management strategies in the post cut bamboo forest.
