This study showed that straw returning aggravated the incidence of rice bacterial wilt at the same level of fertilizer input (Table 1), which may be due to continuous straw returning improving the fertilizer supply capacity and fertility level of the surface soil (Table 2). It affects the depth and breadth of the root system and reduces the cold resistance of rice plants. This is inconsistent with the research report of Li Mingtao (2013) who used straw returning to the field as a prevention and control measure for rice bacterial wilt.

This study shows that under the same level of chemical fertilizer input, straw returning to the field exacerbates the occurrence of rice bacterial wilt (Table 1), which may be due to the continuous straw returning improving the surface soil fertility and supply capacity (Table 2), affecting the depth and breadth of root penetration, and reducing the cold resistance of rice plants, This is inconsistent with the research report by Li Mingtao (2013) regarding returning straw to the field as a prevention and control measure against rice bacterial wilt,
