  After analysing the main quantum secret sharing protocol based on the
entanglement states, we propose an idea to directly encode the qubit of quantum
key distributions, and then present a quantum secret sharing scheme where only
product states are employed. As entanglement, especially the inaccessable
multi-entangled state, is not necessary in the present quantum secret sharing
protocol, it may be more applicable when the number of the parties of secret
sharing is large. Its theoretic efficiency is also doubled to approach 100%.
