矿区退化土地土壤改良剂的研制

Study of soil improver for abandoned land in ming area mining area

为了解决矿区土地的退化问题,对阜新矿区煤矸石山生态环境、煤矸石及其风化物的物理化学生物特性作了综合阐述,同时,对作为煤矸石山复垦的土壤改良剂的沙土的物理化学性质也作了分析。通过试验将沙土和煤矸石按照不同的比例混合,种植当地特征植物黄豆和谷子,利用不同比例下植物的生长状况得出沙土和煤矸石的最佳配比。盆栽试验表明当沙土和混合土壤总重的比例为17%时,最适宜黄豆生长,当比例为67%时最适宜谷子生长。这个试验可为大面积煤矸石山复垦提供参考数据。

In this paper,we give a composite elaboration about ecological environment,gangue and weathering physical,chemical and biological characteristics of Fuxin coal gangue hill,and as for soil improvers of the reclamation of coal gangue hill,its physical and chemical properties were also analyzed.We mixed sand and gangue according to diffierent proportions and grow local planst： soybeans and millet.Then we find the best proportion.The pot experiment indicated： when the sandy soil and the total soil weight proportion is 17%,it is suitable for soybean to grow,and 67% for millet.This experiment may provide the reference data for the similar big area gangue mountain reclamation.
