摘要

The objective of this study was to determine the effects of soil amendments such as chicken litter and viscera in combination with soil Solarization on populations of soilborne plant pathogens and pepper growth and yield, Solarization of plots supplemented with chicken litter and viscera was performed by mulching soil with a single layer of 0.030-mm-thick, clear, nonembossed, UV-stabilized, low density transparent polyethylene plastic sheets for 9 week in 2001. In the greenhouse conditions, the highest soil temperature were 54.8 and 53.6℃ at Sites 1 and 2 in July, respectively. At Sites 1 and 2, chicken litter amendment to soil prior to Solarization increased soil temperature by approximately 2-6℃, respectively, compared with the temperature of nonamended solarized soil at the 5 cm depth. There was little difference in soil temperatures between viscera amended and nonamended solarized plots at all depths of the soil. At both sites, pepper yield during 2001 to 2002 growing season in the amended solarized plots was significantly (p=0.05) higher than those in the nonsolarized plots. At a 5 cm depth, soil solaiization had the highest effect on F, oxysporum and Pythium sp,,, with.78.6 and 56.7%, respectively, at Site 1, Solarization+viscera amendmentwas ineffective in suppressing S sclerotiorum, Pythium spp. and F oxysporum, except that Phytophthora spp. at all depths at Site 2. Soil Solarization did not reduce population densities of R. solani and Phytophthora sp. at all depths. None of the soil treatments were effective in reducing population densities of soilborne pathogens at 25 cm depth.
