This invention relates to the fields of agricultural biotechnology and environmental remediation technology, specifically to a novel, highly efficient, and safe formulation for promoting plant growth and degrading soil phthalates, and its application. The formulation comprises (R)-5-hydroxymethyldihydrofuran-2-one and water. Experiments have shown that (R)-5-hydroxymethyldihydrofuran-2-one, at a concentration of 0.01 mM, has a significant growth-promoting effect on cruciferous vegetable Chinese flowering cabbage (Pachira aquatica), while simultaneously accelerating the degradation of dibutyl phthalate (DBP) in the soil, achieving a dual function. Experiments also show that applying 0.01 mM of A-like to DBP-contaminated soil significantly increases the plant height, root length, and biomass of Chinese flowering cabbage, promotes earlier flowering, and reduces the residual amount of DBP in the soil by 77.2%, with a degradation promotion rate exceeding 62%.

The invention discloses a Chinese cabbage clubroot-resistant gene BrRLP30 and application thereof. The nucleotide sequence of the Chinese cabbage clubroot-resistant gene BrRLP30 is as shown in SEQ ID No.1.
