长期定位试验长期定位试验long term experiment中联系作物生长及产量的演变而分析一种作物或某一种植方式的有关生态指标。诸如水热动态、光合效能、产出投入比值、物质循环和养分平衡等，以觅求保持农田生态良性循环和理想的物质转换效率。 (李实烨)长期定位试验(long term。xperiment)在固定田块上多年连续进行相同处理试验的农业定位研究方法.在农业化学研究中应用最早。通过定位研究.可以全面评价肥料的单项效应、复合效应以及连续施用后的挤加效应和平均效应.由于农业生产受气候因家及人为条件的影响而产生波动，采用长期定位试脸还可以总结年度演变的规律，取得可靠的科学资料。发展概况长期定位试验在国外已有悠久的历史.J.鲁茨(Lawes)为了验证J.von.李比希(Liebig)的矿质营养学说而进行过屁肥、屁肥灰分和氮、磷、钾化肥的系列对比试脸，其中在洛桑试验站(RothamstatExperiment station)的小麦连种施肥试验已达150多年.在此之前，J.v.D.布森高(Boussingault)曾通过轮作试脸而探索了植物氮素营养平衡的基本规律。在水田方面，日本鸿巢县(Konosu)进行的单季稻连种施肥试脸也有近70年的历史.所有这些试验和研究的结果，都对阐明植物营养的需求、指导化肥生产和应用以及提离农作物产t起到积极作用，因而对当地国民经济的发展作出重要贡献，有关政府部门均给以法律保护和泉高的评价.中国定位试验起步较晚.从70年代开始，陆续进行了有关的定位试验.其中浙江省农业科学院土坡肥料研究所在黄岩市进行的“大麦双季稻”三熟制连种施肥试验已达20多年之久。试验结果曾为南方各省稻田发展三熟制、增产粮食和指导合理施肥，提供了技术措施和科学依据。199。年国家计划委员会下达指示，在全国主要农区建立9个土壤肥力和肥料效益长期监侧墓地，业已投入运转。这将为开展中国农业长期定位试脸工作奠定基础。研究内容在农业化学方面主要研究在一定的自然和人为条件下，从土城肥力、施肥效应、增产效果和 生态环境等方面系统监测长期演变的规律，为制订国 民经济发展的总体方案，提供决策依据:①土坡肥力的 发展。长期定位监测土城肥力演变的动态，可以评价在 一定种植方式下施肥能否保持土坡肥力稳定提高，是 否会减退。与此同时还能了解土城中养分数量和质量 的积累和转化以及盈亏状况，从而掌握土坡肥力发展 的动向，有助于研究调节维护地力而达到充分发挥土 壤增产潜力的目的。
