【摘要】 通过盆栽试验和大田试验,研究了结缕草种子在粉煤灰以及大田土壤中的发芽率,分析了结缕草草坪建植期使用粉煤灰控制杂草的效果.结果表明:粉煤灰盆栽结缕草的发芽率为83%,大田土壤盆栽的发芽率为84.33%;在结缕草建植期使用粉煤灰覆盖控制杂草效果明显,且厚度以2cm左右为宜,杂草控制率可达96%以上.本试验的研究结果对综合利用粉煤灰,解决粉煤灰环境污染和占地问题提供了一个新思路.更多还原

【Abstract】 Based on the pot experiments, the germination rates of Zoysia Japonica planted in coal-ashes and in soils were examined, and then the weed protection by coal-ashes in the field planted with Zoysia Japonica was investigated in the period of lawn construction. The results indicate that the germination rate of Zoysia Japonica planted in coal-ashes with pot experiments is 83%, while that of CK is 84.33%. In field experiments, the rate of weed protection by coal-ashes exceeds 96%. And the favorite thickness of coal-ashes was about 2 cm.更多还原
