Abstract
Wood vinegar is widely used as a strong antioxidant, bacteria prevention, plant growth agent, an insecticide, and its effectiveness is shown in heavy metal treatment at this time.Wood vinegar liquid contains organic acids and phenols, which are effective in adsorbing heavy metals. Although a lot of studies have been conducted on the adsorption of heavy metals from biochar, the effect of mixing biochar and wood vinegar liquid on plant budding, and soil heavy metal morphology changes few studies have been analyzed.
This paper analyzes the effects of Wood vinegar and biochar on the sprouting of pakchoi grown in different threats of cadmium from the nature of Wood vinegar. As a result, it was confirmed that the optimum concentration of the applied fertilizer wood vinegar that lowers the plant effectiveness of Cadmium was 1.0%. The fresh weight of pakchoi changed significantly in the order of biochar + wood vinegar 1.0% mixing> biochar> control. When 5.0% Biochar was mixed with 1.0% wood vinegar, the immobilization effect of the residual state and the carbonate bound cadmium in the soil was the highest. The combined application of wood vinegar and biochar promotes the germination of pakchoi, and has a significant inactivation effect on cadmium-contaminated soil; the results of analyzing the effectiveness of the mixing of wood vinegar and biochar and separate fertilization for each soil index show that, Compared to before sowing the pH ratio of the mixed treatment of biochar + wood vinegar is higher than that of the single treatment zone, which is as high as between 6.6-6.8, the EC is reduced to 2-59mS/cm width, and the CEC is increased by 0.27-2.21 times. It shows that under heavy metal stress, the mixed treatment of biochar+wood vinegar solution 1.0% is more effective than the treatment of biochar alone and the control.
