浅谈水溶肥和水溶肥优势以及水溶肥的使用方法

浅谈水溶肥和水溶肥优势以及水溶肥的使用方法 德国新陆水溶肥--能够完全溶解于水的多元素复合型肥料 水溶肥优势: 与传统的过磷酸钙、造粒复合肥等品种相比，水溶性肥料具有明显的优势。它是一种速效性肥料，水溶性好、无残渣，可以完全溶解于水中，能被作物的根系和叶面直接吸收利用。采用水肥同施，以水带肥，实现了水肥一体化，它的有效吸收率高出普通化肥一倍多，达到80%-90%;而且肥效快，可解决高产作物快速生长期的营养需求。配合滴灌系统需水量仅为普通化肥的30%，而施肥作业几乎可以不用人工，大大节约了人力成本。已经有越来越多的土肥专家、农业技术推广专家、农资经销商和农民认识到水溶性肥料的重要性。 方法技巧: 如今，水溶肥料作为一种新型肥料，与传统肥料相比，不但配方多样，施用方法也非常灵活，可以土壤浇灌，让植物根部全面接触到肥料，尽情地呼吸各种营养元素;可以叶面喷施，通过叶面气孔进入植物内部，提高肥料吸收利用率;也可以滴灌和无土栽培，节约灌溉水并提高劳动生产效率。施肥过程中，为达到最佳效果，要结合水溶性肥料的特点，掌握一定的施肥技巧。 1(避免直接冲施水溶肥，要采取二次稀释法。由于水溶性肥料有别于一般的复合肥料，所以农民就不能够按常规施肥方法，造成施肥不均匀，出现烧苗伤根，苗小苗弱等现象，二次稀释保证冲肥均匀，提高肥料利用率。 2(严格控制水溶肥施肥量。水溶肥比一般复合肥养分含量高，用量相对较少。由于其速效性强，难以在土壤中长期存留，所以要严格控制施肥量，避免肥料流失即降低施肥的经济效益，达不到高产优质高效的目的。 3(尽量单用或与非碱性的农药混用。比如在蔬菜出现缺素症或根系生长不良时，不少农民多采用喷施水溶肥的方法加以缓解。在此提醒农民朋友，水溶肥要尽量单独施用或与非碱性的农药混用，以免金属离子起反应产生沉淀，造成叶片肥害或药害。 使用范围 水溶肥料作为一种速效肥料，它的营养元素比较全面，且根据不同作物的需肥特点相应的肥料有不同的配方，市场上销售的有蔬菜、果树、花卉、粮食、棉、油类等各类作物的专用水溶肥料。由于水溶肥料的价位较高，因此并未被大面积普及，一般消费区域主要集中在大棚蔬菜生产基地、果树生产基地以及一些花卉等种植区，比如我国的辽宁、河北、山东、新疆、四川、广西、云南和海南等地区是水溶肥料的重点消费区域。由于蔬菜生长周期短，经济效益高，消费者对蔬菜的质量要求高，进而菜农对肥料的要求也较高，水溶肥料则成了菜农们的首选肥料，种植出来的优质蔬菜能卖出好价钱，带来高利润，所以蔬菜成为水溶性肥料的消费主体。对于大田作物，由于其成本较高，所以百姓一般不愿意投入，还是只接受传统的肥料。 国内现状 is completed in time for said items taken from the balance box, put weights in the weight box, turn the index back to zero position.
