目的:探究不同栽培方式(土壤栽培、营养液栽培、基质栽培)对鸡毛菜保鲜品质的影响。方法采用理化分析、感官评定和多指标GSI(general stability index)综合分析方法,测定了含水量、叶绿素、维生素C、硝态氮等品质指标。结果不同的栽培方式对鸡毛菜营养品质和保鲜指标存在不同的影响;土壤栽培方式下,硝酸盐含量远远高于其他两种栽培方式。结论无土栽培的鸡毛菜营养品质优于土壤栽培;随着贮藏时间的延长,鸡毛菜的品质逐渐衰退,在4℃的低温贮藏条件下,适宜的保质期为5天。
目的:探究不同栽培方式(土壤栽培、營養液栽培、基質栽培)對鷄毛菜保鮮品質的影響。方法採用理化分析、感官評定和多指標GSI(general stability index)綜閤分析方法,測定瞭含水量、葉綠素、維生素C、硝態氮等品質指標。結果不同的栽培方式對鷄毛菜營養品質和保鮮指標存在不同的影響;土壤栽培方式下,硝痠鹽含量遠遠高于其他兩種栽培方式。結論無土栽培的鷄毛菜營養品質優于土壤栽培;隨著貯藏時間的延長,鷄毛菜的品質逐漸衰退,在4℃的低溫貯藏條件下,適宜的保質期為5天。

Objective To discuss the effects of different cultivation patterns (soil culture, hydroponics, substrate cultivation) to pakchoi fresh quality. Methods The physical and chemical analysis, sensory evalua-tion and GSI (General Stability Index) comprehensive analysis method were adopted to measure several quality indicators including the water content, chlorophyll, vitamin C and nitrate nitrogen. Results The nutrition and fresh quality indexes from three cultivation modes of pakchoi were different. The Nitrate content under soil cultivation was far higher than other two kinds of cultivation modes. Conclusion The soilless way for pre-serving pakchoi quality was better than that of soil cultivation. As time went on, the quality of Chinese little greens gradually declined. Under the condition of 4℃, the shelf life was 5 d.
