Abstract:
The physicochemical and biological properties of albic soil was deteriorated, which seriously reduced the crop yield. The biochar has unique physical and chemical properties, and has the theoretical basis for improving albic soil. This experiment was conducted to investigate the effects of different biochar dosages on the albic soil physicochemical properties and soybean yield. The results showed that biochar could increase the water permeability of albic soil. The initial infiltration rate, average infiltration rate, stable infiltration rate and total infiltration of A3 treatment were 3.64, 2.75, 2.89 and 3.03 times of CK respectively. The biochar increased the content of available phosphorus, available potassium, total nitrogen, total phosphorus and organic matter at different growth stages. The biochar increased the yield per plant and seed number per plant, the A2 and A3 yield increased by 61.83% and 58.45% respectively than the control, the seed number of treatment of A1-A3 were 18.8%, 48.8% and 51.2% higher than the control respectively.
