芦花台园林试验场,地处银川市西北部的贺兰山洪积扇之底部,于六十年代初期开垦种植。二十年来防护林虽初具规模,但因园地周围空旷,对防御西伯利亚寒流的侵袭仍然不理想,加之本区地处内陆,昼夜温差大,春秋季气温多变,果树霜冻年有发生。71、72、74、76、77、80年均因霜冻,果树有不同程度的减产,尤以71、72、80三年为甚,造成苹果几乎绝产和葡萄减产的局面。 Luhuatai garden test ground, located in the northwest of Yinchuan Helan Shan alluvial fan at the bottom, reclaimed in the early 1960s planting. Although the shelterbelt has begun to take shape over the past two decades, its invasion to the Siberian cold is still not satisfactory due to the open area around the park. In addition, the area is inland with a large temperature difference between day and night, and the temperatures in spring and autumn are changing. 71, 72, 74, 76, 77, 80 years due to frost, fruit trees have reduced production to varying degrees, especially in 71,72,80 even three years, resulting in almost absolutely apple and grapes cut.
