摘要
为使粮食持续稳产高产,提高土壤肥力,分别在土壤肥力高、中、低的田块开展稻草还田土壤肥力监测试验。试验结果表明,秸秆还田不仅能改善土壤结构和理化性状,还能增强土壤微生物的活性,有利于改善土壤微生态,增加土壤有机质含量,对培肥地力具有良好作用。
In order to enhance grain yield and soil fertility stably, an experiment of straw-field-returning＇s impact on soil fertility in different fertility degree fields was conducted. The results show that straw-field-returning can improve not only soil structure and physical-chemical characters but also enhance the activity of soil microorganism, benefiting the improvement of soil micro-ecology, increasing soil organic matter contents so that it has a positive impact on fostering soil fertility.
