１９８６年引进美国“水围墙’样品并对其保护作用进行了观测研究。于天津郊区利用水围墙可在３月下旬定植番茄，定植期比露地早熟栽培提早了１个月。３月中旬～４月上旬水围墙内的气温平均值比塑料薄膜小棚（以下简称小棚）低２．２～０．７℃；４月下旬～５月中旬比小棚高０．９～２．２℃。水围墙内气温的最高温度低于小棚而夜间温度高于小棚．水围墙对内部土壤的增温作用在３月下旬至４月下旬，比露地高０．９—１．５℃；比小棚低２．４—７．２℃。在同期定植的情况下（番茄）利用水围墙的早期产量比常规露地栽培增加９倍、比露地覆盖地膜增加６．３５倍；但其早熟和增产效果不如小棚。
In 1986, the United States introduced the “water wall” samples and its protective effect was observed and studied in the suburbs of Tianjin using water walls can be planted in late March in tomato, planting earlier than the open field cultivation one month earlier in mid-March ~ 4 The average temperature in the water wall in early month was 2.2-2.7 ° C lower than that of the plastic film shed (hereinafter referred to as the shed), and 0.9-2.2 ° C higher than the shed in late April to mid-May. The maximum temperature of water in the wall temperature is lower than the shed and the night temperature is higher than the shed.Water wall on the internal soil warming in late March to late April, 0.9-1.5 ℃ higher than the open field; The shed was 2.4-7.2 ℃ .In the same period of planting (tomato) using water wall early production increased 9 times than conventional open-field cultivation, 6.35 times more than the plastic film mulching; but its premature and yield The effect is not as good as shed.
