| Abstract: |
| The laboratory experiment of water washing for driving salinity and micro-plot experiment were conducted to study the dynamic effect of Shihezi and Canada peat drive salinity movement from gray desert soil. Their results show that peat accelerates the salt moving down and its mount, and correspond to its experiment show that peat prevents obviously the salt rising up in the soil, especially the result of preventing salt moving up in micro-plot experiment is better than laboratory, salt concentration has never been increased in the farming layer of 30 cm after one month. So results are that peat accelerates the salt moving down and prevents the salt rising up in the soil. But peat from different places is different from content and character, so its effect is different in some ways. Generally Shihezi peat is better than Canada peat. |
