摘要
采用室内盆栽模拟试验,通过研究煤炭矿区1,2,3a复垦土壤中全磷、速效磷、有机质及微生物数量来分析生物菌肥对复垦土壤熟化的效果。结果表明:加入生物菌肥后,不同年限复垦土壤中全磷、速效磷、有机质及微生物数量明显增加,但对不同复垦年限土壤提高效果不同。总体而言,3a复垦土壤的质量好于2a和1a复垦土壤。
Through the rape potted simulation trial, the total phosphorus, quick-acting phosphorus, organic matter and microorganism in one-year, two-year, and three-year reclaimed soil were tested and the effect of the biological bacterial fertilizer to reclaim the soil maturation was analyzed. The result indicated that after application of the biological bacterial fertilizer, the content of the total phosphorus, quick-acting phosphorus, organic matter and microorganism in the soil of all time range increase obviously, but the improvement effect were different. In one word, quality of the 3-year reclaimed soil is better than that of the one-year and two-year reclaimed soils.
