摘要
试验结果表明，在整个果树生长期内，覆盖可明显增加各土层中真菌的数量，０ ～２０ｃｍ 土层中，年平均真菌数量增加７９ ．３９％ ，２０ ～４０ｃｍ 土层中增加２８ ．２４ ％ ，４０ ～６０ｃｍ 土层中增加８５ ．０５ ％ 。无论覆盖与对照，不同土层真菌数量年变化均呈单峰曲线变化，高峰出现在８ 月份。
Study results showed that fungus in soil layers increared significantly by covering for the whole growth period. Fungi number increased by 79.39% for the layer of 0～20cm, 28.4% for the layer of 20～40cm, and 85.05% for the layer of 40～60cm. The variations of fungi contents in all tested layers of both covering and CK were unimodal distribution. The peaks appeared in August.
