泥炭作为一种重要的腐植酸资源，比褐煤和风化煤腐植酸分子缩聚作用小，活性强，比煤炭具有更好的物理、化学和生物学特性。榆林地区泥炭目前处于开发和利用的初始阶段，根据榆林地区泥炭的资源性质、特征和社会经济条件，提出榆林泥炭资源开发利用对策，不仅具有重要的理论意义，对提高引领和带动榆林泥炭新兴产业的发展，加强榆林泥炭资源的保护和管理也具有重要的实践意义。液体肥料由于具有生产费用低、养分含量高、易于复合、能直接被农作物吸收、便于配方施肥（平衡施肥）和机械化施肥等诸多优点，受到越来越多的关注。用泥炭生产液体肥料，即就是生产腐植酸类液体复合肥料。 本文是利用榆林地区泥炭生产腐植酸类液体复合肥进行的理论研究。 本文首先对榆林地区泥炭中的成分进行测定分析；然后，对泥炭腐植酸的抽提方式及抽提条件进行了大量的实验比较，得出了一套合适的抽提方法；再则，根据液肥行业的相关国家标准，进行液肥的配制，并对所配制液肥进行检验性试验（包括大量元素测定、微量元素测定、种子萌发试验和种植试验等）；最后，结合生产成本、市场条件及社会经济条件等众多因素，对榆林地区泥炭生产腐植酸类液体复合肥的应用前景进行综合评价。

The peat took one kind of important humic acid resources, are smaller than the lignite and the decency coal humic acid member polycondensation, active, has a better physics, chemistry and the biology characteristic compared to the coal. The Yulin area peat is in the development and the use preliminary stage at present, according to the Yulin area peat resources nature, the characteristic and the social economy condition, proposes the Yulin peat resources development use countermeasure, not only has the important theory significance, to enhances eagerly anticipates and leads the Yulin peat emerging industry the development, strengthens the Yulin peat resources the protection and the management also has the important practice significance. Because the liquid manure has the production cost low, the nutrient content high, easy compound, to be able by the crops absorption, to be advantageous for the formula to apply fertilizer directly (balance to apply fertilizer) and the mechanization applies fertilizer and so on many merits, receives more and more many attention. With the peat produces the liquid fertilizer, namely produces humic acid liquid complex fertilizer. This article is the theory study which carries on using Yulin area peat produces humic acid liquid complex fertilizer. This research first carries on the determination analysis to in the Yulin area peat coal ingredient; Then, extracted the method and the condition to the peat humic acid has carried on the massive experimental comparison, obtained a set appropriately to extract the method; Moreover, according to the fluid fat profession related national standards, carries on the fluid fat configuration, and to compounds the fluid to carry on the examination evaluation fat (massive element determination, trace element determination, seed sprouts experiment and planter experiment and so on); Finally, with progress of production cost, the market condition and the social economy condition and so on the multitudinous factors, carry on the quality synthetic evaluation to the Yulin area peat produces humic acid liquid complex fertilizer's application prospect.
