摘      要：In the frame of the Sino-ltalian Cooperation Program for Environmental Protection, jointly launched in the year 2000 by the Italian Ministry for Environment and Territory and Sea （IMETS） and the China State Environmental Protection Administration （SEPA）, experimental trials were carried out in Qingzhou city （Shandong Province, China） during 2001-2003 to test several methyl bromide alternative methods to control soilborne diseases in greenhouse tomatoes. Grafting tomatoes on resistant rootstock （Lyeopersicon lycopersicum × L. hirsutum）, metham sodium applied under traditional polyethylene plastic films; metham sodium applied at low rate under virtually impermeable films and soil sotarization combined with biocontrol agents were the alternatives tested and compared to methyl bromide applied under virtually impermeable plastic films too. Collected data show that resistant rootstock （Lycopersicon tycopersicum × L. hirsutum） introduced from Italy is a promising alternative to methyl bromide for local tomato cultivars. Metham sodium applied under traditional polyethylene plastic films is an effective alternative. Moreovez virtually impermeable films demonstrate the help to reduce methyl bromide and metham sodium rates. Finally soil solarization combined with biocontrol agents does not provide satisfactory results in terms of disease control.
