无土栽培技术是近百年来新发展起来的一种栽培技术，是当今农业现代化生产技术的代表，无土栽培技术就是不用天然土壤，而利用含有植物生长发育所必须的元素的营养液来提供营养，并使得植物能够正常地完成整个生命周期的种植技术。无土栽培技术可以分为多种类型，其中以水培方式最为常见，水培是指植物根系直接生长在营养液层中的栽培技术。水培作物一般生长周期短，复种指数高，生产经济效益高，产品质量好，具有鲜嫩，洁净，口感好，是解决蔬菜淡季供应的有效方式，可进行周年生产。水培生产的成功与否，取决于营养液配方是否合适，因此，研究不同营养液配方对水培苦苣的影响具有一定的理论意义和使用价值。

Soil ess cultivation techniques are developed in the last century a new cultivation techniques,is the modernization of agriculture production technology representatives, soil ess cultivation technology is not the natural soil,and the use of plant growth and development must contain the elements of the nutrient solution to delive nutrition,and makes plants can normal y complete the entire life cycle of planting techniques.Soil ess cultivation techniques can be divided into several types,of which the most common way of hydroponics,hydroponic refers directly to plant roots grown in nutrient solution layer cultivation techniques.General Hydroponics crop growth cycle is short,cropping,high production and high economic ef iciency,product quality is good,with fresh,clean,good taste,is to solve the of -season vegetables supply an ef ective way to conduct annual production.Hydroponic production success depends on nutrient solution formula is appropriate,therefore,study of dif erent hydroponic nutrient solution formula for the impact of endive has some theoretical significance and value in use.
