By research on the concentration change and distribution of methyl bromide in the container, we found that in the first period of fumigating, the absorption of the goods to methyl bromide became quickly, so did the concentration decline of the fumigant because of leakage of the carton itself. The distribution of the fumigant is not uniform in the aclinic and vertical directions. The absorption of the goods to methyl bromide completed after 6 hours delivered the gasified fumigant and the distribution of the concentration in space got balance.

The Hg could inhibit seed germination of Alisma orientale Juzepcz, no seed germination was observed under the Hg solution in this experiment, the reason needs to be studied in the near future. Atrazine along concentration gradient could stimulate seed germination except the low concentration. The seed germination increases with the increasing atrazine content. When the atrazine concentration reaches 50mg/L, the seed germination reaches its peak.
