| 摘 要： | 在长期定位监测的基础上，研究了耕作改制对土壤肥力的影响，结果表明，耕作改制后，肥料投入明显增加，养分平衡朝着有利于提高肥力的方向发展；因土、因作物进行配方施肥，并实行秸秆还田，则改制后土壤肥力能得到提高；合理耕作轮作，有利于解决地力矛盾和季节矛盾，实现高产、稳产、低成本。

| Abstract: | The effects of different cropping system on soil fertility were studied by long-term stationary experiments. The results show that the fertilities of soils have increased as application rates of fertilizer were raised after changing crop system. Balanced fertilization and straw returns can economically and effectively improve the soil fertility. The rational cropping system is propitious to solve the conflict between soil fertility and crop season, and can achieve high yield and low cost. |
