通过2003~2004两年的试验发现,刈割覆盖、刈割压埋、畜粪还园三处理纤维分解菌和硅酸盐细菌的数量均明显高于清耕处理(对照),且两种微生物数量均以夏季最多,秋季次之,春季再次,冬季最少。前三处理蔗糖酶、脲酶、过氧化氢酶、纤维分解酶、多酚氧化酶的酶活性都较清耕有显著或极显著提高;各处理酶活性也以夏季最高、秋季次之,春季再次,冬季最低。2004年刈割覆盖、刈割压埋两处理蔗糖酶、脲酶、过氧化氢酶活性较2003年有显著或极显著增加,畜粪还园、清耕两处理三种酶活性两年间差异很小。经相关性分析还发现,纤维分解菌除与脲酶相关性不显著外,它与其余的酶均显著或极显著正相关;硅酸盐细菌与所有的酶均极显著正相关。
The results of two years from 2003 to 2004 showed that mulching, mowing and embedding, and manure-returning and returning to the garden were significantly higher than those under tillage (control), and the number of both microorganisms The most in summer, autumn followed, again in spring, winter at least. The activities of sucrase, urease, catalase, fibrolytic enzyme and polyphenol oxidase in the first three treatments were significantly or extremely significantly increased compared with those of pure tillage. The activities of enzymes in the first three treatments were the highest in summer, the second in autumn and the second in spring The lowest in winter. In 2004, the activities of sucrase, urease and catalase were significantly increased or significantly increased compared with those of 2003, and the activities of three activities of animal manure returning garden and clearing land two treatments were very small in two years . Correlation analysis also found that the fibrolytic enzymes had significant or very significant positive correlation with other enzymes except urease, while silicate bacteria had significant positive correlation with all the enzymes.
