摘要
[目的]研究坑施肥水技术对陕北丘陵区苹果园土壤理化状况的改良效果。[方法]设坑施肥、常规穴施、常规条施3种施肥模式，通过比较3种施肥模式对苹果园土壤保蓄供给水平及土壤理化性质，研究坑施肥水技术对延安苹果园土壤改良的效果。[结果]3种施肥模式的肥水效果从高到低依次为坑施肥、常规穴施、常规条施；3种施肥模式的理化性质均以坑施肥模式最好，常规条施模式最差。[结论]坑施肥水对干旱少雨的丘陵区果园的集水效果和施肥效果较好，值得推广应用。
Abstract
Objective] The aim was to study the improvement effect of applying water fertilizer in pit on apple orchard soil in hilly region of Northern Shaanxi.[Method] By using three fertilization modes including pit fertilization , conventional cave fertilization and conventional strip fertilization, soil preservation level and physicochemical properties in apple orchard were compared , the improvement effect of applying water fer-tilizer in pit on apple orchard soil in Yanan was studied.[Result] The soil improvement effect and physicochemical properties with three fertiliza-tion modes from good to bad is pit fertilization, conventional cave fertilization and conventional strip fertilization.[Conclusion] Applying water fertilizer in pit has good effect on hilly orchard with little rain and drought , it is worthy of popularization and application.
