- 摘要:
- 以生菜“罗生3号”为试材，利用冷水机降温技术对越夏水耕栽培营养液进行降温处理，研究了该技术对生菜产量和品质的影响。结果表明：利用冷水机降温技术将营养液温度控制在 (20±1)℃，对生菜生长和干物质累积具有明显的促进作用，且不会影响生菜的品质。说明该技术应用于越夏水耕栽培营养液温度调控是完全可行的。
- Abstract:
- Lettuce ‘Luosheng No.3’ was used as material，in order to explore the feasibility of nutrient solution cooling using a water cooler machine for hydroponic lettuce，the effect of nutrient solution temperature control on the growth and quality of hydroponic lettuce over summer in greenhouse was studied.The results showed that the nutrient solution temperature could be maintained at a suitable range (20±1)℃ for lettuce growth.The growth and dry matter commutation of lettuce was promoted.There was no negative impact on the quality of lettuce.In summary，it was feasible for the water-cool technology applied to the hydroponic solution temperature management.
