The contents of organic matter, total nitrogen phosphorous and potassium, and effective nitrogen, phosphorous and potassium at different layers of soil in mulched irrigated. 测定了3种梨园&不灌覆盖园、不灌无覆盖园和灌溉园不同土层中有机质、全氮、全磷、全钾和速效氮、速效磷、速效钾的含量。
Soil nitrogen and potassium content under different coverage of bryophyte had little difference, while soil phosphorous content was significantly different. 方差分析结果显示,不同苔藓盖度下土壤中氮、钾含量差别不大,磷含量差异显著,没有苔藓覆盖的土壤中磷含量最高,为0.419±0.023g.kg-1;
