Based on the scenario that the $K_0^\ast(1430)$ is viewed as the ground stateof $s\bar{q}$ or $q\bar{s}$, we study the $K_0^\ast(1430)$ leading-twistdistribution amplitude (DA) $\phi_{2;K_0^\ast}(x,\mu)$ with the QCD sum rulesin the framework of background field theory. A more reasonable sum rule formulafor $\xi$-moments $\langle\xi^n\rangle_{2;K_0^\ast}$ is suggested, whicheliminates the influence brought by the fact that the sum rule of$\langle\xi^0_p\rangle_{3;K_0^\ast}$ cannot be normalized in whole Borelregion. More accurate values of the first ten $\xi$-moments,$\langle\xi^n\rangle_{2;K_0^\ast} (n = 1,2,\cdots,10)$, are evaluated. A newlight-cone harmonic oscillator (LCHO) model for $K_0^\ast(1430)$ leading-twistDA is established for the first times. By fitting the resulted values of$\langle\xi^n\rangle_{2;K_0^\ast} (n = 1,2,\cdots,10)$ via the least squaresmethod, the behavior of $K_0^\ast(1430)$ leading-twist DA described with LCHOmodel is determined. Further, by adopting the light-cone QCD sum rules, wecalculate the $B_s,D_s \to K_0^\ast(1430)$ transition form factors andbranching fractions of the semileptonic decays $B_s,D_s \to K_0^\ast(1430) \ell\nu_\ell$. The corresponding numerical results can be used to extract theCabibbo-Kobayashi-Maskawa matrix elements by combining the relativeexperimental data in the future.
