Abstract: To take full advantage of southern fruit waste, compost of abandoned stems and leaves of banana and pineapple and coir were used as substrates, adhesion agent, curing agent and modifying agent were added into the matrix to make matrix block. According to the physicochemical property of different matrix blocks, orthogonal experiments were performed to screen the best matrix block formula. The results showed that the ratio between compost and coir was the main influence factor of physicochemical property of matrix block. The order of different influence factors was substrate composition > modifying agent > adhesion agent > curing agent. In general, the A3B2C3D3 formula had the best physicochemical property, this formula contained substrate composition (compost:coir=4 : 6), 4% adhesion agent (polyving alcohol), 2.5% curing agent (borax) and 140% modifying agent.
