[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。
[Objective] The research aimed to study the effect of pit fertilization water on soil physical and chemical conditions in apple orchard in hilly area of northern Shaanxi. [Method] Three kinds of fertilization modes including pit fertilization, conventional hole acupuncture and conventional one were applied. By comparing the three kinds of fertilization modes on the soil conservation and supply of apple orchard and soil physical and chemical properties, effect. [Result] The results showed that the fertilizer and water effects of the three kinds of fertilization modes were pit fertilization, conventional hole application and conventional one from high to low. The physical and chemical properties of the three fertilization modes were the best in the pit and the worst in the conventional mode. [Conclusion] Keng fertilization water had a good water harvesting effect and fertilization on hilly orchard in arid area, which deserved to be popularized and applied.
