一、花卉及景观的无土种植无土栽培迄今仅有数十年历史,虽是一门很年轻的学科、但已被广泛应用到许多方面,如自动化植物_厂厂、温室蔬菜种植等,显示出了许多公认的优点,其发展大有前途。无土栽培在初期发展之际,大多数园艺业者都站在与此对立或怀疑的立场。皆自人类有种植的历史以来,都是把植物种在土壤之中。目前从国外的新趋势看来,不只在室内用无土种植观赏植物,而且还用来大面积种植蔬菜及繁殖观赏植物,有些国家甚至还计划用无土栽培方法种植农作物。在无土栽培的研究领域中,以栽培基质种类(即土壤代用品Soil substitutes或人工土壤)及供养施肥系统最为重要。另外,在景观工程上应用无土利植亦逐渐受到重视。用无上栽培方法种植观赏植物,不仅可美化和绿化生活环境,同时也是一种很好的室内装饰,给人们增加许多美的感受。无土种植比使用土壤种植更易于
First, the soilless cultivation of flowers and landscapes Soilless cultivation so far only a few decades of history, although a very young subject, but it has been widely used in many aspects, such as automated plant _ factory, greenhouse vegetable cultivation, etc., It shows many recognized advantages and its development is promising. Soilless cultivation At an early stage of development, most horticulturalists stand on the opposite or skeptical position. Since the human history of planting, all plants are planted in the soil. At present, it seems from the new trend of foreign countries that not only soilless ornamental plants are used indoors, but also large-area vegetables and ornamental plants. Some countries even plan to grow crops by soilless cultivation methods. In the field of soilless culture research, the most important is the cultivation of substrate types (ie soil substitutes or artificial soils) and the provision of fertilization systems. In addition, the application of soilless planting landscape engineering has also gradually been taken seriously. Planting ornamental plants with the supreme cultivation method not only beautifies and greens the living environment, but also is a good interior decoration, giving people more beautiful feelings. Soilless planting is easier than using soil planting
