The Effect of Mix-Plants Type and Proportion on Water Retention Characteristic for Seedling Bricks

Abstract:

Wheat straws, wheat shells, corn leaves and corn cobs (0%, 5%, 8% and 10%) were added to red clay to obtain seedling bricks, pure red clay as control (CK), did evaporation test. The results showed that the larger of the proportion of mix-plant was, the smaller the cumulative evaporation of seedling bricks was. The cumulative evaporation of seedling bricks mixed with 10% corn cob was the minimum. In all seedling bricks, the order of 1st day evaporation suppression efficiency and cumulative evaporation suppression efficiency I_E: mixed with corn cobs > mixed with wheat shells > mixed with wheat straws > mixed with corn leaves > mixed with nothing, and evaporation suppression efficiency of seedling bricks mixed with 10% corn cobs was the maximum. With the proportion of mix-plant increases, evaporation stability, evaporation suppression efficiency and water retention characteristic of seedling bricks were improved significantly.
