陕西省泥炭油页岩草炭三种有机矿藏资源基本性状及农业利用的可行性分析

Analysis of basic properties and feasibility of utilized in agriculture of three organic mineral resources of Shaanxi

对陕西蕴藏的泥炭、油页岩和草炭3种主要有机矿藏所含的有机物质、矿质养分、水溶性盐分含量和重金属组成进行了系统测定分析,结果表明:在农业应用中,3种有机矿藏资源的最大优势是有机质含量高;限制性因素是沥青含量高、水溶性盐分含量高(尤其是硫酸盐含量高)、重金属砷含量高。在农业利用中可以作为混合基质的配料使用,不宜直接作为栽培基质。

Organic matter, ＂mineral nutrient, water-soluble salt and heavy metals were systematic analyzed in peat, oil shale and turf in Shaanxi. The results showed that the best advantage is the high content of organic matter, and the limitative factors are the high contents of asphalt, water-soluble salt （especially the content of SO4^2- is very high） and heavy metals （As）of the three mineral resources utilized in agriculture. Therefore, they can be used as one of the compositions of a mixed substrate, not directly as a cultural substrate.
