摘要
以樱桃番茄品种PFZL为试材,开展了利用可调节根际温度的无土栽培系统(ARTS)进行番茄越冬栽培加温保温效果的试验研究。结果表明,该系统可有效缓解基质温度受空气温度的影响,保持基质温度的稳定性;明显改善根际温度,基质温度控制在20~25℃之间,平均温度稳定在22~23℃;冬季采用该系统加温可促进番茄株高和茎粗的生长,每667 m2产量1527.05 kg,比常规栽培装置增产39.94%;较传统的锅炉加温方式平均节能72.90%,冬季加温运行费用为0.33元·m^-2·月-1,远低于燃煤锅炉加温的0.94元·m^-2·月-1,具有显著的增产、节能效果。
Taking cherry tomato variety‘PFZL’as test material,this paper carried out experimental studies on overwinter tomato cultivation using soilless culture system with adjustable rhizosphere temperature.The results showed that this system could effectively alleviate the influence of substrate temperature by air temperature,maintain the stability of matrix temperature,and significantly improve the rhizosphere temperature.Thus,the matrix temperature was controlled between 20-25℃,and the average temperature,between 22-23℃.In winter adopting this system could promote the growth of tomato plant height and stem diameter.Tomato yield could reach 22.9 t·hm^-2,increased by 39.94%than that of the conventional tomato cultivation.Compared with the traditional boiler heating method,the average energy saving was 72.90%.The heating operation cost in winter was 0.33 yuan·m^-2·month-1,which was significantly lower than 0.94 yuan·m^-2·month-1 by the coal-fired boiler.Obviously,this system has significant yield increasing and energy saving effects.
