The Effect of Different TillageManagement and Working Depth on Maize Production

  • 摘要: 为了比较不同耕作方式和工作深度对玉米生产的影响,在华南农业大学农场进行了两组对比试验,试验土壤为沙壤土和粘壤土,试验作物为玉米。第一组试验中安排了5种耕作方式,分别为犁耕加圆盘耙(MB+DH),凿形耕(CH),圆盘耙两次(DH2),旋耕(RT)和不耕(NT),第二组试验中安排了2种耕作方式,犁耕加圆盘耙(NDL)和犁耕、圆盘耙加深松(NL)。试验结果表明,不同的耕作方式和工作深度对土壤容重、土壤耕
    Abstract: This research was conducted to study the effect of different tillage management systems (TMS) and working depth on maize production. The TMS used in experiment 1 were moldboard + disc harrow (MB+DH), chisel (CH), disc harrow twice (DH2), rotovator (RT) and no-tillage (NT) as a control. This experiment was conducted on a sandy loam soil. The results showed highly significant differences between treatments. The chisel (CH) significantly influenced maize growth parameters, reduced soil bulk density, soil tillage resistance, increased soil moisture at all depths and finally gave higher maize yield and yield components parameters while the no-tillage (NT) treatment gave the lowest performance. Experiment 2 was conducted on a clay soil with two treatments, no deep loosening (NDL) 20 cm depth and deep loosening (DL) 40 cm depth using tine. The results showed that the deep loosening significantly increased soil moisture, reduced soil bulk density, soil tillage resistance and finally increased maize production.
