- 摘要:
- 以H型和A字型2种不同高架栽培模式下的连栋温室热水管道根区加温系统为试验对象，采用在北京地区冬春季最寒冷时段对其性能进行测试的方法，研究了不同栽培模式对温度环境和加温均匀性的影响，以期对草莓根区加温方式优化提供参考依据。结果表明：H型和A字型栽培模式下的空气温度平均值分别为14.4 ℃和15.5 ℃，A字型栽培模式下的最高空气温度较H型高1 ℃；2种栽培模式下的基质温度平均值均为13.8 ℃，A字型栽培模式下的最高基质温度较H型高1.3 ℃；A字形栽培模式下中间槽的基质温度最低值较左右槽高1.3 ℃。H型栽培模式下基质温度测点的最低值偏离度为0%~11%，平均值为1.1%；A字型栽培模式下基质温度测点的最低值偏离度为4.5%~25.3%，平均值为17.4%。2种栽培模式下的空气和基质温度均基本达到草莓生长环境需求，H型栽培模式加温均匀性较A字型高。
- Abstract:
- The root zone heating system by hot water pipe in multi-span greenhouse under two different elevated cultivation modes of H-type and A-type was proposed as experimental object,and its performance was tested in the coldest period of winter and spring in Beijing.The effects of different cultivation modes on temperature environment and heating uniformity were studied and analyzed,in order to provide practical basis for the optimization of heating mode in strawberry root zone.The results showed that the air temperature average of H-type and A-type was 14.4 ℃ and 15.5 ℃ respectively,and the highest air temperature of A-type was 1 ℃ higher than H-type;the substrate temperature average of both cultivation modes was 13.8 ℃,and the highest substrate temperature of A-type was 1.3 ℃ higher than H-type;the lowest substrate temperature of middle trough under A-type cultivation mode was 1.3 ℃ higher than left and right trough.The minimum deviation of substrate temperature was 0%-11% and the average was 1.1% under H-type cultivation mode.The minimum deviation of substrate temperature was 4.5%-25.3% and the average was 17.4% under A-type cultivation mode.The air and substrate temperature of two cultivation modes basically met the needs of strawberry growth environment,and the heating uniformity of H-type cultivation mode was higher than that of A-type cultivation mode.
