Improper disposal of debris from the demolition of houses has led to a continuous expansion of environmental and soil pollution areas. The research objective is to focus on the proportion and greatest harm of concrete blocks and red bricks in building debris. Method: Crush the concrete blocks and red bricks separately, using two different weight ratios of crushed particles as a mixture. Add different weights of soil and organic fertilizer to the mixture, and pour it into 10 flower pots to plant wheat for experimentation. Result: The order of good survival rate of wheat in pots is: ③ > ⑤ > ⑥ > ④ > ② > ① = ⑦ > ⑧ = ⑨ = ⑩. Conclusion: When the difference between the weight of the mixture and the sum of soil and organic fertilizer weights exceeds 1kg, crop failure occurs. Under mixed conditions, the soil aeration and infiltration capacity in the pot increase, resulting in a shortened irrigation cycle for wheat. Finally, the calculation formula for residual loss will be explored to provide a basis for the rational utilization of building debris and the control of pollution area.展开更多
