国内外泥炭基质养分比较研究
Comparisons of Nutrient of Peat Growing Mediumes by Domestic and Foreign Manufacturers
【摘要】 通过对国内使用较广泛的进口泥炭和国产泥炭的养分研究,明确国产泥炭与进口泥炭之间的养分差异。与进口泥炭相比,国产泥炭的养分含量较高,其中全N含量是进口泥炭的2~3倍,全P含量是进口泥炭的3~5倍。国产泥炭的Na、Ca、Fe、Mn元素含量都远高于进口泥炭,Mg元素略高于进口泥炭。国产泥炭的pH高于进口泥炭,有机质含量低于进口泥炭。通过国内外泥炭养分含量的比较,为提高国内泥炭资源的园艺利用效率提供理论支持。
【Abstract】 Objective to study the difference of nutrient of domestic and foreign peats,through the analysis of the chemical characteristics of domestic and foreign peats.The results show that compared with the peat produced by foreign manufacturers,the domestic peat had a higher nutrient content.The N and P contents of the domestic peat were 2~3 and 3~5 times higher than the foreign peat,and the Na Ca Fe and Mn contents of the domestic were much higher than the foreign peat.The pH was higher and the content of organic matter was lower than foreign peat.This artical was to improving the utilization efficiency of domestic peat for horticulture by the comparisons of nutrient of domestic and foreign peats.
