- 摘要:
- 为研究不同土壤管理方式对苹果园土壤养分含量的影响，选择庆阳市不同区域生草覆盖、黑膜覆盖和清耕（对照）3种管理方式，对90个苹果园土壤进行养分分析。结果表明：生草覆盖和黑膜覆盖0～30、30～60 cm土层中土壤有机质、全氮、速效氮、全磷、有效磷、全钾、速效钾的含量均高于清耕（对照），提高了果园土壤的基础肥力，增加了土壤的养分含量，其中生草覆盖对增加土壤养分更为显著，在苹果园管理上应大力推广。
- Abstract:
- Grass cover，black film mulching and clean tillage three managements in Qingyang different regions were chosen to study the effect of different soil management methods on soil nutrient content in apple orchard.The results showed that contents of soil organic matter，total nitrogen，available nitrogen，total phosphorus，available phosphorus,total potassium and available potassium of grass cover，black film mulching (0-30 cm,30-60 cm)were all higher than that of clean tillage(CK)，which improving basic fertility and nutrient content in orchard soil，while grass cover improved the soil nutrient content more obviously，which should be vigorously promoted in apple orchard management.
