旱季灌溉施肥条件下桉树人工林光合特性日变化和季节变化与环境因子的关系

该论文通过室内模拟；桉树常规生产种植后进行旱季灌溉；为提高季节性干旱区尾巨桉人工林生产力提供了重要的实践探索。最终得出桉树大部分日光合速率和呼吸速率呈“单峰”曲线、环境因素影响着桉树昼夜和季节的光合特性、旱季灌溉缓解了其生长的轻度干旱胁迫等结论。

This paper carried out indoor simulations and dry-season irrigation following the conventional commercial cultivation of Eucalyptus urophylla × E. grandis, providing important practical explorations for enhancing the productivity of Eucalyptus plantations in seasonally arid regions. It finally concluded that most daily photosynthetic rates and respiration rates of Eucalyptus exhibit unimodal curves, that environmental factors influence the diurnal and seasonal photosynthetic characteristics of Eucalyptus, and that dry-season irrigation alleviates mild drought stress during its growth.
