摘  要:
测定分析了华东型连栋塑料大棚内深水培营养液液温日变化和溶解氧量的消减动态。结果表明:营养液液温与大棚内气温呈极显著的正相关,但液温的日变化相对平缓;营养液溶氧量随栽培槽长度的增加而降低,因此深水培栽培樱桃番茄时,种植槽长度不宜过长。

摘  要:
The paper deals with the variation of nutrient solution temperature and dissolved oxygen content in DFT system for cherry tomato culture in plastic glasshouse. The results showed that the temperature of nutrient solution was positively correlated with air temperature in glassroom significantly. But diurnal variation of solution temperature was relatively slower. The dissolved oxygen content of nutrient solution decreased with increasing of length DFT bed. So the length of DFT bed should not be too long while applying DFT to cherry tomato cultivation .
