摘　　要：通过对不同耕作模式下土壤中可溶性盐分EC值的测定及其对春玉米株高、产量性状的影响研究。结果表明,秋深松+秋施肥+秋旋耕+中黑炭(黑炭施入量14 999 kg/hm^2)模式可以有效降低土壤中可溶性盐分含量,促进植株生长发育,显著提高作物产量。The paper measures the EC value of soil soluble salt and studies the effects on height and yield of spring corns through different farming modes. The results show that the model of deep scarification in autumn ＋ fertilizer in autumn ＋ rotary tillage in autumn ＋black carbon（14 999 kg/hm^2 of volume of black carbon）on soil can effectively reduce the soluble salt content in the soil, promote plant growth and development, significantly improve crop production.
