Abstract:
To study the influence of tillage method at different seasons on the advantage weed populations in Codonopsis pilosula (Franch.)Nannf.field and the influence of synergistic effect between tillage method and weeds on the Codonopsis pilosula (Franch.)Nannf.yield.We chose four tillage methods at two different seasons in three years in a row,they were respectively no-tillage,deep ploughing and no rake flat,deep ploughing and rake flat,rotary tillage.The results showed that the annual weeds Corispermum declinatum Steph.ex Stev.var.declinatum,Capsella bursapastoris (Linn.) Medic., Chenopodium album L., Setaria viridis (L.) Beauv.,and the perennial weeds Convolvulus arvensis L., Agropyron cristatum (Linn.) Gaertn.were the advantage populations in the Codonopsis pilosula (Franch.)Nannf.field.The kinds and numbers of the weeds were the highest and yield of Codonopsis pilosula (Franch.)Nannf.was the lowest with no tillage.The kinds and numbers of the weeds were both the lowest and the yield of Codonopsis pilosula (Franch.)Nannf.was the highest with deep ploughing and rake flat at summer drought.The weeds could be controlled effectively by deep ploughing and rake flat at high temperature and drought in summer.It could reduce the cost of the weeding,and increased the yield of Codonopsis pilosula (Franch.)Nannf..It can be popularized and applied as the green weeds control technique.
