| 摘 要： | 对秸秆还田长期田田试验的前3季产量结果和1年后土壤农化性状进行分析.结果表明,江汉平原稻一麦两熟制下.秸秆在下李作物上原位还田,并辅以快速腐解茵,能明显提高作物产量,尤其是在与化肥配合施用时.其增产量随着秸秆还田量增加而增加;同时秸秆还田还能提高土壤有机质舍量,并能改善土壤的速效钾和速效磷的供应能力,秸秆原位还田及快速腐解是一项很好的提升土壤肥力的技术.

| Abstract: | The fiehl experimental results show that the straw reapplieation may increase the yiehls of paddy rice and wheat significantly, especially while fertilizers is applieated together. The yield increases occur with the amount of straw reapplication. The measurement of returning straw into soil can effectively increase the content of soil organic matters, and improve the supply capability of the soil nutrient such as available K and P. |

| Keywords: | straw reapplications yield soil fertility |
