一、目的: Avadex BW作为土壤处理剂,在防除恶性杂草野燕麦方面越来越显示了其优越性。为了明确Avadex BW在土壤中是否能够形成扩散层,使之保持其药效的发挥,为生产应用上提供理论依据,我们在室内进行了Avadex BW在土壤中扩散作用的试验并对扩散距离及何距离为野燕麦中毒最佳距离进行了研究。 First, the purpose: Avadex BW as a soil treatment agent, more and more shows its superiority in the control of wild weed wild oats. In order to find out whether Avadex BW could form a diffusion layer in the soil and maintain its efficacy, and provided a theoretical basis for production and application, Avand BW indoors was used to test the diffusion effect of Avadex BW in the soil. The distance to the wild oat poisoning the best distance studied.
