| 4. | But there is few report on exactly the relationship till now . the no - tillage and ridge culture is just the good example to study it
但目前国内外对有机残体周转与微生物关系的深入研究较少，影响了有机残体的返还和利用。 |
| 5. | And the models of the turnover and circulation of organic matter in no - tillage and ridge culture are be used as a base and a start to the relationships
自然免耕在这方面提供了极好的素材，在本文中正是以自然免耕的有机残体物质循环为切入点，研究土壤中有机质的周转与微生物的关系。 |
| 6. | Then , in order to pursue effect of soil humidity to the relationship between the turnover of organic matter and the micro flora , the no - tillage and ridge culture simulated experiment is carried out to find out the exactly reasons for the high level of organic matter and assoc
可见，大量的有讥残体的返还是土壤有机质增加的充分条件：影响土壤有机质的积累的表面上是耕作和轮作制度，而实质是有机残体的返还量及其适宜的分解、周转条件。 |
| 7. | First , the dynamics of soil properties in different period during a year from the long - term no - tillage and ridge culture experiment field are researched in order to get the general dynamic properties of organic matter , chemical substances , microbe , ph and eh in soil
首先通过对自然免耕定位试验的有机残体的分解与转化的动态特征研究，得出有机残体分解转化过程中的有机质、养分、微生物及出和eh的动态特征，总结出有机残体分解与微生物关系的一般规律。 |
| 8. | 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。 |
| 9. | Academician hou guangjiong , who summarized the experiences from peasants in sichuan province , promoted the no - tillage and ridge culture in 1982 that has two sides of meaning of its name : one is simulating the physical and ecological characteristics of originally moist soil ; the other means rhat the basic characteristic of perfect soil fertility is no - tillage . the key of no - tillage is the supply the past crop residue to soil
1982年侯光炯院士根据四川农民和农村科技工作者的实践经验，在总结覆盖免耕和残茬免耕的基础上提出了自然免耕制，其名称有两方面的涵义，一是模拟自然土高肥力的生理生态特征；二是说明高肥力的基本特征是免耕。 |
| 10. | Recent no - tillage and ridge culture commenced in the united states in the 1930s . it was developed to prevent the erosion of water and soil and to avoid the wind and water erosion . not until the atrazine herbicide was invented and successfully used in the 1960s was the nt technique succeeded and spread
近代的免耕始于20世纪30年代的美国，为了防治水土流失，防止风蚀和水蚀而发展起来的，到60年代，阿特拉津除草剂的发明利用，才使免(少)耕法得以成功应用和推广。 |
