通过对1987～1990年在阳泉白家庄矿区人工堆垫土上进行不同培肥试验,结果表明: 无论施肥种植禾谷类作物,还是种植豆科作物,只要管理合理,均有改善土壤肥力状况,尽快培肥熟化的结果,特别是选用豆科作物作为先锋植物,在干旱少两矿区,土壤有机质、全氮、速效磷、微生物数量均比生黄土有成倍提高的效果,并基本可达当地种草的后估高产水平,是一项经济快速培肥措施。同时,增施化肥、农肥,对加速矿山人工堆垫土的培肥熟化,调节和维持土壤肥力的平衡发展,同样具有重要意义。
Through the experiment of different fertilizers on artificial heap paddy soil in Baijiazhuang mining area of Yangquan from 1987 to 1990, the results showed that no matter fertilizing the planting of cereal crops or leguminous crops, so long as the management is reasonable, the soil fertility conditions are improved, As soon as possible, the results of fertilization and maturation, especially the use of leguminous crops as pioneer plants, increased soil organic matter, total nitrogen, available phosphorus, and microbial biomass in the arid and shallow mining areas by a factor of several, Estimated high-yielding grass species, is a rapid economic fertilization measures. At the same time, it is also of great significance to increase chemical fertilizers and agricultural fertilizers to speed up the fertilization and maturation of artificial mound of paddy soils, and to adjust and maintain the balanced development of soil fertility.
