| 摘 要： | 为了明确国内外蔬菜育苗用草炭理化特性的差异，采用筛分和理化分析的方法，比较分析了国外丹麦品氏、芬兰凯吉拉、德国泰林康和克莱斯曼以及国内辽宁清原县、吉林辽源县、黑龙江桦川县、黑龙江延寿县产的8种草炭的理化性质。结果表明：国内草炭分解度偏高，多为H3～H5，而国外草炭分解度较低，集中在H1～H2范围|国内草炭粒径小于0.5 mm部分所占比例是国外草炭的4～10倍|国内草炭饱和持水量明显小于国外草炭，平均饱和持水量约是国外草炭的1/2|国内草炭全N、全P、全K、碱解N含量普遍高于国外草炭，但国内草炭速效P、速效K含量明显偏低。

| Abstract: | In this study,we analyze the physiochemical properties of peat-moss for vegetable seedling production.Some remarkable differences are found between 4 overseas peat-moss(from Denmark,Finland,Germany)and 4 domestic peat-moss(from Qingyuan County of Liaoning Province,Liaoyuan County of Jilin Province,Huachuan County and Yanshou County of Heilongjiang Province).The results indicate that the decomposition degree of domestic peat-moss is H3-H5,much higher than that of the overseas peat-moss(H1-H2).Therefore,the ratio of<0.5 mm particle is greater,about 4-10 folds over the overseas peat-moss.Also,the saturation moisture content of the domestics is lower,only 50% of the values obtained from the overseas peat-moss.Furthermore,we demonstrate that compared to the overseas,the domestic peat-moss contains higher content of total N,P and K,available N,but lower content of available P and K. |
