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。 On the basis of long-term monitoring, the effects of tillage and rebuilding on soil fertility were studied. The results showed that after tillage and reformation, the input of fertilizers increased obviously and the balance of nutrients developed in the direction of increasing fertility. Because of soil and crop fertilization, , And the implementation of straw, soil fertility after restructuring can be improved; reasonable farming rotation, is conducive to solving the contradiction between the geo-forces and seasonal conflicts, to achieve high yield, stable yield, low cost.
