| 摘 要： | 本文阐述了在NFT系统上试验探讨营养液溶氧量与环境因子的相关关系,就如何改善溶氧供给,提出若干改进NFT设施设计的建议,如:适当加大贮液池;在贮液池上附设循环液的喷洒装置;适当扩大栽培床的槽腔;夏天采用低温的地下水配制贮液池中营养液,或降低温室(大棚)的气温。

| Abstract: | By exploring the significant relationship between the environment fectors and the oxygen content of nutrient solution in NFT system, some suggestion a bout engineering design of the NFT system are offered to improve oxygen supply to roots. For instances:· Enlarging the volume of solution tank properly;· Attaching the sprinkling device of circulating solution;· Enlarging the tunnel of bed properly.Using the cold underground water to make up the nutrient solution in the tank, or reducing the greenhouse temperature in summer. |
