为推进秸秆资源的循环利用,改善农田土壤质量,利用田间小区试验研究了水稻秸秆还田后的腐解特征,分析了水稻秸秆还田后对土壤性质及油菜产量的影响,结果表明:水稻秸秆的腐解率一直呈增加趋势,腐解速率早期快后期慢;水稻秸秆在耕作后还田腐解效果要大于免耕还田;水稻秸秆还田不仅提高了土壤养分含量,而且提高了油菜的产量。
In order to promote the recycling of straw resources and improve the quality of farmland soil, the decomposing characteristics of rice straw after field application were studied by using field plot experiments. The effects of straw on soil properties and rapeseed yield were analyzed. The results showed that: The decomposing rate has been increasing, and the decomposing rate is slow in the early and late period. The effect of returning the straw to the soil after returning tillage is greater than that of no-till and returning to the field. Rice straw addition not only increases soil nutrient content, but also raises the Yield.
