%X With greenhouse plastic film, rice straw plus greenhouse plastic film, soil-mulching plastic film, rice straw, rice straw plus sun-shading net, and sun-shading net as test mulches, this paper studied their effects on the rhizosphere temperature, growth, and physiological properties of flue-cured tobacco. The results showed that after mulching for 22 days, the accumulative rhizosphere temperature at the depth of 5 cm was the highest (424.75 degrees C) for greenhouse plastic film and the lowest (378.75 degrees C) for rice straw plus sun-shading net, while that at the depth of 15 cm was the highest (396.75 degrees C) for greenhouse plastic film and the lowest (368.31 degrees C) for sun-shading net. With the increase of accumulative rhizosphere temperature, the dry weight of above- and underground parts, photosynthesis, and root vigor of flue-cured tobacco tended to increase, and at the 10th day after mulches removal, root biomass had the largest increment in the treatment of soil-mulching plastic film and the smallest increment in the treatment of rice straw plus sun-shading net.
