水溶性肥料主要包括叶面肥料和灌溉施用肥料,是我国未来最具发展潜力的新型肥料品种类型之一。首先,随着我国大量施用高纯度化肥和获得持续作物高产,农田的中微量元素长期得不到及时补充,土壤中微量元素缺乏越来越严重,而叶面肥料是矫正作物中微量元素缺乏最有效的手段,比土壤矫正见效快、效果好。其次,水溶性肥料有利于实现水肥一体化,节水、节肥、配方灵活。水溶性肥料的研究首先是从叶面施肥的角度开始,20世纪20～60年代,主要以大量元
Water-soluble fertilizers mainly include foliar fertilizers and fertilizers for irrigation applications. It is one of the most promising new fertilizer types in the country. First of all, with the large-scale application of high-purity fertilizers and sustained high crop yields in China, long-term replenishment of trace elements in farmland has not been achieved, and the lack of trace elements in soil has become more and more serious. Foliar fertilizer is the most critical factor in correcting trace elements in crops. Effective methods are quicker and effective than soil remediation. Secondly, water-soluble fertilizers are conducive to the integration of water and fertilizers, water-saving, fertilizer-saving, and flexible formulations. The study of water-soluble fertilizers was first started from the perspective of foliar fertilization. From the 20th century to the 20th century, it mainly focused on a large number of yuan.
