We hypothesized that (1) there may be significant differences in the ecosystem N, P, and K cycling characteristics due to the heterogeneous effects of nutrient elements; (2) whole-tree harvesting would have a negative impact on the ecosystem N, P, and K cycling functions because whole-tree harvesting causes substantial nutrient loss; (3) whole-tree harvesting may regulate nutrient cycling functions differently due to the significant disturbances it causes to vegetation, soil, and the overall environment. 2.
Effect of calcium spray on fluorine and calcium content in tea plant leaves With increasing exogenous Ca concentration, the Ca content showed an increasing trend in the leaves of tea seedlings, with an increase of 11.00%, 24.15%, 36.12% and 38.86% in the Ca present treatments (0.05, 0.25, 0.5, and 1 mM Ca) respectively versus the control (0 mM Ca), indicating that the Ca content in the leaves of tea plant is significantly affected by the Ca spray level ( Figure 1C ).
