基于Meta分析的黄土高原苹果园土壤改良措施效果评价

Shuitu Baochi Xuebao
[目的] 黄土高原苹果园直接面临土壤酸化、结构恶化、肥力退化及保水能力差等问题,有效的土壤改良技术对改善黄土高原苹果园土壤质量、促进果园的健康和可持续发展至关重要。[方法] 基于黄土高原苹果园土壤改良的75篇文献1 302对田间试验数据,采用Meta分析和主成分分析(PCA)定量评估不同改良方式(覆盖、施肥和土壤改良剂)对土壤质量的改善效果。[结果] 生草覆盖、地膜覆盖、秸秆覆盖和砂砾覆盖降低土壤质量密度效果良好,降低幅度分别为6.63%,5.96%,6.04%,6.40%,其中 ...

不同林龄人工林根系性状、枯落物特性对土壤质量的影响

Shuitu Baochi Xuebao
目的探讨不同林龄人工林根系性状与枯落物特性对土壤质量的影响及其驱动作用，明确影响土壤质量随林龄增加而变化的关键植物因素。方法以不同林龄毛白杨（Populus tomentosa）、侧柏（Platycladus orientalis）和国槐（Styphnolobium japonicum）人工林为研究对象，测定其土壤理化性质、根系性状、枯落物碳氮质量分数与持水特性，并探讨根系与枯落物对土壤质量的驱动作用及其随林龄变化的规律。结果1）随林龄增加，人工林土壤质量指数均增大 ...
