通过长期定位施肥试验地第9年的小麦收获期取土测定土壤酶活性的结果表明:有机肥和无机氮肥配合施用对土壤酶的活性影响最显著;土壤酶的活性与土壤的主要化学性状有显著相关性.
Soil enzyme activity was measured by soil-harvesting at the 9th year of wheat harvest with long-term fertilization experiment. The results showed that the combination of organic manure and inorganic nitrogen fertilizer had the most significant effect on soil enzyme activity. The activity of soil enzyme and the main chemical properties of soil were Significant correlation.
