深液流无土栽培(DFT)营养液管理技术

Nutrient Solution Management Technique on DFT

营养液是无土栽培的关键,以黄瓜深液流无土栽培营养液为研究对象,根据实际测得的营养液温度,溶解氧和电导率,观察其试验数据判断对黄瓜生长的影响,并对其进行合理调控和管理,使其在特定时期维持在一定的范围之内,协调好它们之间的相互关系和相互影响,让黄瓜更好地正常快速生长。这一实践性的技术,将有利于无土栽培技术的提高与发展,为今后研究提供依据和方法。

The nutrient solution is the key point of DFT.Taking the cucumber nutrient solution as the object of study,according to the actual temperature of the nutrient solution,dissolve（fertilizer） oxygen and the conductivity,observing the impact of the judgment testing a data over cucumber growth,being regulated and managed reasonably,making it maintain within a certain range in specially appointed period,coordinating the interrelation and mutual effect between them,let the cucumber grow better and rapidly.This practical technology will be beneficial to the improvement and development of the soilless cultivating technique,providing the basis and method to the future study.
