随着水危机影响到几个国家，在灌溉农业中使用创新的技术和方法是提高水利用效率的关键。使用磁化水被认为是节约水资源和提高作物产量和质量的一种可能性。在此基础上，本研究的目的是评价不同灌溉深度和磁场处理水对观赏向日葵(Heliantus annuus L.)花茎的生长和寿命的影响。处理包括作物蒸散量(ETC)的5%(ETC的20%、70%、100%、130%和160%)和两种灌溉用水(磁化水和普通水)。测定了株高、茎粗、花序直径、叶和茎的鲜重和干重、花序的鲜重和干重以及花茎的采后寿命。不同水分类型对其生长和采后寿命特性无明显影响。灌溉深度的增加促进了所有分析参数的增加。关于切花的商品化模式，深度等于或大于0.7等得出的观赏向日葵分类最好。
ABSTRACT With the water crisis affecting several countries, the use of innovative technologies and methods in irrigated agriculture is essential to increase water use efficiency. The use of magnetised water has been considered a possibility both for saving water resources and in increasing crop productivity and quality. Following this, the objective of the present study was to evaluate the growth and longevity of flower stems of ornamental sunflower (Helianthus annuus L.; Vincent’s Choice) irrigated with different irrigation depths and water subjected to magnetic field treatment. The treatments consisted of five percentage of crop evapotranspiration (ETc) (20, 70, 100, 130, and 160% of ETc) and two types of irrigation water (magnetised water; and ordinary water). The following characteristics were evaluated: plant height, stem diameter, inflorescence diameter, fresh and dry masses of the leaves and stems, fresh and dry masses of the inflorescence, and post-harvest longevity of the flower stems. The growth and post-harvest longevity characteristics were not influenced by the water type. An increase in irrigation depth promoted an increase in all analysed parameters. Regarding the commercialisation patterns of cut flowers, depth equal to or greater than 0.7 ETc yielded the best classification of ornamental sunflower.
