Degradable ecological gypsum brick, and preparation method and application thereof

The invention relates to the field of ecological building materials, and particularly discloses a degradable ecological gypsum brick, and a preparation method and application thereof. The degradable ecological gypsum brick is prepared from calcined gypsum, diatom ooze, grass seeds, a natural fertilizer, a hardness enhancer, a water-retaining agent, a surfactant, a natural coloring agent, degradable particle balls and water. Each degradable particle ball comprises a ball shell and a ball core, the ball shell is made of degradable natural fibers, and the ball core is filled with degradation liquid. The preparation method comprises the following steps: preparing the degradable particle balls, and respectively preparing the natural fertilizer and the hardness enhancer; mixing the obtained components and other components, and stirring uniformly, to obtain the ecological gypsum mud; putting the ecological gypsum mud into a mold, and standing to obtain a formed green gypsum brick; and drying the green gypsum brick t
