| 1. | Plant residues harvested in floating culture system as tomato seedling substrate 漂浮栽培系统收获植物残体作为番茄育苗基质的应用研究 |
| 2. | The plant residue decomposing simulated experiment in containers is managed according to those general properties afterward with aims to test and verify them 0和ss3 ,而冬水免耕处理的土壤有机质的增幅不大。 |
| 3. | As we all know : the chief part in decomposing the plant residue is soil microbe . it ' s microbe ' s metabolism that promotes the turnover of substance and organic matter in soil 土壤微生物是影响有机残体分解利用的最主要的因素,是推动土壤有机质分解、转化和循环的动力。 |
| 4. | This study takes the relationships between the turnover of organic matter and microbe as its goat by researching the course of plant residue decomposition and mineralization 在本论文中,有机残体的分解是自始至终的研究内容,有机残体的分解、转化与微生物的关系是论文的研究中心。 |
| 5. | Organic matter is higher at the soil surface because plant residues from either grasslands or no - till are left on the surface whereas residues in conventional fields are mixed in the soil ; giving uniform organic matter 在草地和免耕方式下,植物残体留在土表,所以表层土壤的有机质含量较高,而在传统耕作制下,植物残体被翻入土内,所以各层土壤中有机质含量差别不大。 |
