泥炭(亦称草炭、草煤)在全国土壤普查中发现有大量分布,是农業上一种重要的有机肥料肥源,其中富含有机質、腐殖質及氮素和其他养分元素,但这些养分均呈有机化合物結合,直接施用,一般不易为作物利用,肥效当年不大。因此,提高泥炭肥料的有效性,是开辟肥源的重要工作。据近年泥炭利用研究,除使堆制腐熟及制顆粒混合肥料外,利用泥炭富含的胡敏酸,制取胡敏酸肥料,是泥炭利用的新途徑。
Peat (also known as peat, grass coal) found in the national soil census a large number of distribution is an important agricultural organic fertilizer fertilizer source, which is rich in organic matter, humus and nitrogen and other nutrients, but these nutrients Organic compounds were combined, direct application, the general is not easy for crop utilization, fertilizer year was not. Therefore, improving the effectiveness of peat fertilizer is an important task in opening up fertilizer sources. According to peat utilization research in recent years, in addition to compost compost and granulated compost, the use of peat-rich humic acid to prepare humic acid fertilizer is a new way for peat utilization.
