is the hybrid orbital the solution of Schrodinger equation ?
Or why we have to make orbital hybridization?

You must be very careful here to what Schrödinger equation you are referring. Hybrid orbitals aren't solutions of the time independent effective one particle Schrödinger equation for electrons in an isolated atom. But note that we use them to construct approximate many particle wavefunctions not for isolated atoms but for atoms in a molecule. It turns out that, considering as an example carbon, an atomic wavefunction constructed from one s and three p orbitals -each occupied with one electron- is completely identical to a wavefunction constructed from four singly occupied sp3 orbitals. However, the latter representation is more apt to describe directed bonds in the valence bond formalism.
 
Is this means that the hybrid orbitals is an solution of many atoms schrodinger equation,like we can not get the exact solution so we, depending on the symmetric of molecular, hybridize the s orbital and p orbitals of isolated atom to form the wave function of many atom solution? Or we just solution the equation by computer and found that solution shows like hybridized orbital?
 
Yes, it is an "ansatz" or trial wavefunction.

Thank you Drdu!

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
