无土栽培是将作物植于营养液中,或以不含有机质的沙、蛭石、珍珠沙、煤渣、颗粒塑料等作为基质,用配制的无机盐溶液来满足植物生长需要的一种新的栽培方法其特点是以人工制造的根系环境取代土壤环境,因此,不仅能提供矿质营养、水分和气体,而且能对这些条件加以控制和调整,从而促进植物的生长和发育,使之发挥最大的生产能力,所以,无土栽培的植物生长好,产量高,品质优良,无土栽培花卉清洁卫生,最适宜高级宾馆、酒家、商场、办公楼及居室内部摆设。国际上,土壤种植的花卉受到检疫的限制,而无土栽培则不在限制之列。在花卉生 Soilless cultivation is a new method of planting crops in nutrient solution, or using organic salt-free sand, vermiculite, pearl sand, cinder, granular plastic and so on as substrates to meet the needs of plant growth by formulating inorganic salt solution Cultivation methods are characterized by the artificial environment of the root system to replace the soil environment, therefore, not only provide mineral nutrients, water and gas, but also to control and adjust these conditions, thereby promoting the growth and development of plants to maximize its Therefore, soilless culture plants grow well, yield high quality, soilless culture flowers and sanitation, the most suitable high-level hotels, restaurants, shopping malls, office buildings and living room furnishings. Internationally, flowers planted on soil are subject to quarantine restrictions, while soilless cultivation is not a limitation. Health in flowers
