【摘要】 在辽宁省抚顺市,初步研究了不同复垦措施对矿区废弃地土壤化学性质和植物生长的影响。结果表明:(1)不同植物在矿区废弃地的成活率在21%～85%之间。其中白榆和沙打旺的成活率分别为81%和85%;小叶杨、刺槐、栾树的成活率均在70%左右:(2)植被能明显提高矿区废弃地不同土层的有机质、全N、全P和全K含量,但提高程度随土壤层厚度和养分种类的改变而不同。(3)生物复合肥料、生物菌剂、保水剂以及三者共同使用能改善主要造林树种的生长状况,但不同措施对造林树种生长状况的改善程度不同。更多还原

【Abstract】 The effects of different reclamation measures on soil chemical properties and plant growth in mining wasteland were studied in Fushun city, Liaoning province. The results showed that (1) The survival rate of different plant was from 21%-85%. The survival rate of Ulmus pumila and Astragalus adsurgens was 81% and 85% irrespectively and the value of Populus simionii, Robinia pseudoacacia and Rekoelreuteria panaiculata was about 70%. (2) Vegetation can improve the contents of organic matter, total N, total P and total K in different soil depths, but the degree of improvement changed with soil depths and nutrient varieties. (3) Biological compound fertilizers, biopreparate, absorbent polymers and usage of the them together can improve the growth of the mam tree species, out rne improvement aeg(?) different reclamation measures varied.更多还原
