Zusammenfassung:The invention discloses a method of promoting colonization of delftia tsuruhatensis at plant rhizospheres, and provides application of mucic acid in the aspects of promoting colonization of delftia tsuruhatensis at the plant rhizospheres and preparing preparations for promoting colonization of delftia tsuruhatensis at the plant rhizospheres. By adopting the method, a signal molecule, namely mucicacid capable of promoting colonization of delftia tsuruhatensis at the plant rhizospheres is screened out from secretions of plant root systems, research shows that mucic acid has significant chemotactic and swarming effects on delftia tsuruhatensis and can significantly promote colonization of delftia tsuruhatensis at the plant rhizospheres; besides, when mucic acid and delftia tsuruhatensis comeinto play together, reproduction of delftia tsuruhatensis at the plant rhizospheres can be significantly promoted; the total fresh weight, the total root weight, the plant height, the chlorophyll content and the root system n
