摘　　要：通过培育试验研究了6种有机物料对山地果园红壤中碱解氮、速效磷和速效钾含量的影响。结果表明,不同有机物料对山地果园土壤碱解氮含量的影响依次为：大豆秆〉印度豇豆秆〉烟杆〉菌棒〉稻草〉猪粪,培育末期（第110天）,各处理土壤碱解氮的含量比对照增加了7.918～30.362 mg·kg-1;对土壤速效磷含量的影响依次为：菌棒〉猪粪〉印度豇豆秆〉大豆秆〉烟杆〉稻草,磷素的最大释放率依次为：菌棒〉烟杆〉猪粪〉稻草〉大豆秆〉印度豇豆秆;对土壤速效钾含量的影响依次为：烟杆〉大豆秆〉印度豇豆秆〉菌棒〉猪粪〉稻草;钾素养分的最大释放率依次为：烟杆〉稻草〉大豆秆〉印度豇豆秆〉猪粪〉菌棒。The experiment is to study the effects of six different organics application on available contents of nitrogen,phosphorus and potassium in mountain red soil. The results showed that for available nitrogen the effects were soybean stalk Poona pea stalk tobacco stem bacteria stick straw pig manure. At the end of the experiment（ 110 d）,the six treatments got an increase of available nitrogen ranged from 7. 918 mg·kg- 1to 30. 362 mg·kg- 1compared to CK treatment. And for available phosphorus,the effects of different organics were bacteria stick pig manure Poona pea stalk soybean stalk tobacco stem straw. The maximum release rate of phosphorus element was bacteria stick tobacco stem pig manure straw soybean stalk Poona pea stalk. The effects of different organics on available potassium were tobacco stem soybean stalk Poona pea stalk bacteria stick pig manure straw. Maximal release rate of potassium element was tobacco stem straw soybean stalk Poona pea stalk pig manure bacteria stick.
