These 71 plants of trees would be treated by using the treatment of toxicity soil combined with powder, the first control group would be treated by anti-termite powder, and the second group would be given no treatment. After 50 days'treatment, it was found that the treatment rate of toxicity soil combined with powder was 93%, with stable effect and no repeatability; the treatment rate of anti-termite powder was 33.3%, with unstable effect and repeatability, and it was needed to change and add medicament again and again so as to make sure that trees would no longer be damaged by termite; there still existed termite hazard in the second group without treatment. By contrasting different treatment methods, it could be known that treatment of toxicity soil combined with powder had obvious advantage, harmless to human body and environment, and could replace traditional medicaments and methods with strong toxicity.展开更多
