无土栽培(Soilless Culture)是近四十年发展起来的新型栽培植物的方法,是直接利用无机营养液而不用土壤种植植物的方法。早期的无土栽培技术主要用于特殊地区如海岛驻军生产蔬菜,目前已被许多国家广泛用于作物、蔬菜、果树、花卉及药用植物的栽培,其技术也得到不断地改进和完善。一、无土栽培的特点无土栽培技术以人工创造的模拟根系环境替代了自然的土壤环境,不仅能提供植物生长所需的营养元素、水分和空气.还能进行人工调控,最大限度地满足植物生长发育需要,有着土壤栽培无法比拟的优越性。 1.无土栽培技术极大地改善
Soilless Culture is a new type of cultivated plant that has been developed in recent 40 years. It is a method of directly using inorganic nutrient solution instead of soil to grow plants. Early soilless cultivation techniques are mainly used for vegetables production in special areas such as island garrisons. At present, they are widely used in the cultivation of crops, vegetables, fruit trees, flowers and medicinal plants in many countries, and their technologies have been continuously improved and perfected. First, the characteristics of soilless culture Soilless culture technology artificial artificial roots to replace the natural environment of the soil environment, not only provide the necessary nutrients for plant growth, moisture and air, but also to manually adjust to meet the maximum Plant growth and development needs, with soil cultivation incomparable superiority. 1. Soilless cultivation techniques have greatly improved
