The invention discloses a quinclorac herbicide-caused tobacco phytotoxicity restoration method comprising the following steps: using stereo leisure plowing technology to combine bamboo charcoal with vinasse fertilizer according to proportion for mixture application; using a soil displacement tool to plow the 20-30cm soil layer onto the surface in tobacco transplanting; plowing the 0-20cm soil layer under the surface; applying the vinasse fertilizer and tobacco rod charcoal on the surface of the soil; shallowly plowing so as to evenly mix the tobacco rod charcoal, vinasse fertilizer and the soil; ridging and transplanting tobacco seedlings; mixing powerful rooting strong seedling Timiaoling +high activity composite bacterial strain product with water so as to serve as rooting water, and pouring the rooting water on the tobacco seedling root in the pit. The method usess the stereo leisure plowing technology to combine bamboo charcoal with vinasse fertilizer, and the soil layer is replaced to loosen the soil; the tobacco growth nutrition is supplemented; exogenous toxic substance in the plants can be removed, thus promoting crops growth, obviously alleviating herbicide phytotoxicity, providing obvious restoration effect, and allowing the tobacco leaf to obviously restore normal botany property and inner quality.
