山西矿山人工堆垫土特性及培肥的研究

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。

STUDY ON THE FERTILIZATION OF MINESOILS IN SHANXI PROVINCE

A fertilization experiment was conducted on the minesoil in Baijiazhuang Aluminum Mine,Yang Quan,Shanxi growing either crops Or grasses with proper management played a role in improving soil fertility and accelerating the maturity of the soil, The amounts of soil organic matter, total nitrogen, rapidly available phosphorus and the number of microorganisms were doubled, compared to those of loess soil, The crop yield reached the yield level of the local farm land Using chemical fertilizers, combined with farmyard manure, is considered as an economic and quick fertilizing measure. which will be of importance in reguliting and maintaining minesoil fertility.
