Abstract: Let $ p$ be an odd prime. In this paper, by using the properties of Legendre polynomials we prove some congruences for $ \sum _{k=0}^{\frac{p-1}2}\binom{2k}k^{2}m^{-k}(\textrm{mod} {p^{2})}$. In particular, we confirm several conjectures of Z.W. Sun. We also pose 13 conjectures on supercongruences.
