| 摘 要： | 多年不同耕作措施试验研究结果表明,土壤理化性状因耕作措施不同而异。长期免耕土壤容重高于连耕;免耕土壤有机质较长期连耕及少耕明显提高;少、免耕的耕层土壤水分高于连耕;免耕土壤有机质高于连耕,少耕(5年)与连耕(26年)相比无明显差异;少耕与长期免耕及连耕相比产量有所提高。

| Abstract: | The results of different tillage with many years showed that physiochemical traits of soil changed with different tillage measures. Furthermore, the volume weight of long-term and no-tillage soil was higher than continuous-tillage, the soil organic matter of long-term and no-tillage had been improved significantly than that of continuous-tillage and less-tillage, water of tillage layer of less-tillage and no-tillage was more than that of continuous-tillage. Moreover, soil organic matter of no-tillage was higher than continuous-tillage. However, there was no difference between less-tillage(5 years) and continuous-tillage(26 years), the yield of less-tillage and no-tillage had been improved with comparing of continuous. |
