Composite structure substrate special for cutting seedling raising

A composite structure matrix special for cutting seedling raising is composed of a seedling raising bowl body, a basic matrix and an inorganic matrix, the basic matrix is contained in the seedling raising bowl body, the inorganic matrix is embedded in the basic matrix in a matched mode or compactly filled in the basic matrix, and the composite structure matrix special for cutting seedling raising is formed through combination. By utilizing a water-air coordination system established in the inorganic substrate and a diffusion gradient formed by nutritional ingredients of the basic substrate in the inorganic substrate, rapid development and rooting of the seedling culture cuttings are ensured, and the generated root system gradually adapts to the environment of the basic substrate while penetrating into the basic substrate; nutrient supplementation is obtained from the basic matrix while a young root system is formed, a seedling strengthening period is directly entered without a rejuvenation period, the whole s
