本文在概括介绍泥炭最新用途的基础上 ,重点阐述泥炭多元稀土颗粒复混肥开发试验的研究成果。具体包括泥炭原料的物化工艺性能评价和泥炭多元稀土颗粒复混肥的原料选取、配方设计、生产技术及加工流程、农作物小区对比试验等。生产泥炭多元稀土颗粒复混肥的技术与流程可以概括为 :将泥炭低温 (<70℃ )烘干 10 h,在碎样机上碎至10 0筛目。按比例用碳铵对普钙进行铵化处理 ,再按配方加入其他原料 ,搅拌均匀后 ,此时即制成掺合型泥炭多元稀土复混肥。若需造粒 ,可加入适量水润湿 ,经造粒机造粒 ,并烘干装袋即可。该肥料开发前景广阔 ,加工技术简单可行 ,具有良好的经济和社会效益。施用它除增产效果比较明显 (较一般无机复混肥平均增产 11.12 % )外 ,还可改良土壤 ,起到缓释和长效作用 ,调节土壤酸碱度 ,提高农作物的抗病能力 ,可望在发展无污染农业方面发挥积极作用。
Based on the introduction of the latest uses of peat, this paper focuses on the research results of the development of peat multivariate composite fertilizers. Including the evaluation of physicochemical properties of peat raw materials and the selection of raw materials for peat multivariate rare earth compound fertilizer, formulation design, production technology and processing flow, comparative experiments of crop plot and so on. The technology and process for producing peat REE composite fertilizer can be summarized as follows: the peat is dried at low temperature (<70 ℃) for 10 h and then broken to 10 0 mesh on a crusher. In proportion to the use of ammonium bicarbonate on ammonium treatment, and then press the formula to join other raw materials, stir, then mixed with peat multivariate made of rare earth compound fertilizer. For granulation, water can be added amount of wet granulation granulation, and drying bagging can be. The fertilizer development prospects, processing technology is simple and feasible, with good economic and social benefits. In addition to the application of its effect is obvious (more than the average inorganic compound fertilizer yield 11.12%), but also improve the soil, play a slow release and long-term effect, regulate soil pH, improve disease resistance of crops is expected to develop Non-polluting agriculture play an active role.
