In research much importance was attached to the study of dry land and the physical , chemical and biologic properties of water land , but the relationship between soil microbes and soil fertility in the paddy field of long - term no - tillage and ridge culture was relatively ignored , so this experiment was conducted for further study 纵观国内外的研究概况，对旱地的研究比较多，对水田的物理、化学和生物性状也有研究，但是，对稻田长期垄作免耕条件下的土壤微生物和肥力的关系的研究尚鲜见报道，因而着手于这方面的研究。
