为了研究地膜- 秸秆双重覆盖模式对渭北旱塬果园土壤养分含量的影响, 对5 个不同处理( 地膜压玉
米秆双重覆盖、地膜压短麦秆双重覆盖、长麦秆压地膜双重覆盖、地膜压长麦秆双重覆盖和无覆盖清耕对照) 下果
园0  ̄ 1 0 0c m 土层深度范围内的土壤养分含量进行测定, 并统计了苹果产量。结果表明: 地膜- 秸秆双重覆盖模式
能显著提高果园土壤养分平均含量, 并提升养分有效性; 其中地膜压短麦秆双重覆盖处理综合效果最佳, 土壤有机
质、全氮、碱解氮、速效磷、速效钾含量均显著高于无覆盖对照( P < 0 . 05 ) , 提高比例分别为29 . 72 % 、8 . 8 2 % 、
1 9 . 35 % 、5 1 . 8 7 % 、22 . 66 % ; 碱解氮含量提高比例高于全氮, 说明该模式能够提高氮肥有效性。与无覆盖对照相比,
地膜- 秸秆双重覆盖模式对土壤剖面养分垂直变异影响不明显, 均呈现出随深度增加先降低后缓慢递增的趋势。
从提高土壤养分含量和提升其养分有效性的角度出发, 利用地膜压短麦秆双重覆盖模式进行果园土壤管理可以成
