1982-1984年在北卡罗来纳州东南部进行了两个试验区的试验，研究了黑膜覆盖丘陵栽培草莓的周年生产潜力。1982-1983年，在10月中旬用新挖的植物进行了一次密度试验，双行之间的植物间距为33厘米，行中的植物间距为15、20、25和30厘米。1983年春季，除“泰坦”外，其它品种均以行距15 cm处理产量最高。所有品种的果实大小有所减少，在较近的间距。在1983-1984年的试验中，将休眠植物的夏季种植与10月中旬新挖的植物进行了比较。1983年12月，创纪录的低温（-14 °C）严重破坏了休眠植物的叶子、树冠组织和开花原基，而新挖的植物在次年春天的冻害较少，果实产量较高。
The potential for annual cropping of strawberries in hill culture on black plastic mulch was investigated using 2 experimental plantings in southeastern North Carolina from 1982-1984. In 1982-1983, a plant density trial was conducted with freshly dug plants set in mid-October at a plant spacing of 33 cm between the double rows and spacings of 15, 20, 25, and 30 cm between plants in the row. Except with ‘Titan’, the highest strawberry yields in the spring of 1983 were obtained at the 15 cm in-row spacing. Fruit size of all cultivars was somewhat reduced at closer spacings. In a 1983-1984 trial, summer planting of dormant plants was compared to that of freshly dug plants set in mid-October. In December of 1983, record cold temperatures (− 14°C) severely damaged leaves, crown tissues, and blossom primordia of dormant plants, whereas freshly dug plants had less freeze injury and higher fruit yields the following spring.
