Shuitu Baochi Xuebao, 2021 为明确滇南地区普洱茶种植下土壤优先路径特征以及根系对其形成的影响，以典型普洱茶产地为研究对象，灌草地为对照，基于染色示踪法与图像处理技术，定量分析普洱茶树根系特征与土壤优先路径的关系，解释根系对优先路径形成的影响。结果表明：（1）茶地和灌草地染色路径宽度随土层深度增加呈不同幅度的下降趋势，茶地优先路径的连通性比灌草地差，优先路径的发育程度小于灌草地；（2）根系主要集中分布在土壤表层，随土层深度增加，根重密度、不同径级根长密度均呈减小趋势，径级≤1 mm的根长密度贡献度最大，达到84.08%；（3 ...

Shuitu Baochi Xuebao, 2021 为了研究坝上地区不同退化程度小叶杨的细根分布特征，使用土柱法对比了未退化、中度退化和重度退化小叶杨的细根在水平和垂直方向的根系参数的分布规律以及差异，并分析了根系参数在不同土层中的占比。结果表明：（1）随着林地土壤含水率逐渐减小，小叶杨的退化程度加重，细根在表层的占比逐渐增加，在深层的占比逐渐减小。（2）在垂直方向上，3种退化程度小叶杨的细根生物量在0—20 cm土层显著高于其他土层（P中度退化>重度退化。（3）在离开树干的水平方向上，未退化和中度退化小叶杨的细根的根长密度呈现出先增加后减小的变化趋势 ...

聚水阻渗措施对矮砧密植苹果园土壤水分、硝态氮及果树细根的影响
Shuitu Baochi Xuebao, 2023 为提高土壤水肥利用效率,探索适宜渭北地区苹果园发展的聚水阻渗措施。通过大田试验,以矮砧密植苹果园为研究对象,分析不同聚水阻渗措施对土壤水分、硝态氮和果树细根的影响。结果表明:在垂直方向,防渗层、起垄+防渗层、起垄+覆膜+防渗层处理均可有效提高0-40 cm土层土壤含水量、硝态氮含量和细根根长密度,其中,起垄+防渗层和起垄+覆膜+防渗层处理土壤含水量和细根根长密度高于防渗层处理,硝态氮含量则低于防渗层处理。在50-100 cm土层,3种处理措施均降低土壤硝态氮含量,有效缓解硝态氮淋溶累积。在水平方向上 ...
