我们开发了一个倾斜的温室和一个适合在倾斜土地上使用的水培系统。为了在冬季有效利用温室和系统，对蓝莓进行了强制栽培研究。将15个品种的蓝莓移栽于装有泥炭苔藓的容器中，并通过水培系统提供营养液。移栽后10 ~ 17个月，对各品种植株间的死亡情况进行了调查。“早期蓝”的植物死亡率最高。我们认为“早期蓝色”不适合水培系统。在强迫栽培中，直到2004年2月3日，在德岛Mikamo的丘陵和山区（海拔约300米）户外种植的植株经历了一段低温期。2月3日之后，这些植物被移入田间附近的加热温室。香川县增须治强行培养植株的开花时间为2月底，比标准培养植株的开花时间早35 ~ 40天。强制栽培植株的收获时间从4月底开始，比标准栽培植株提前了35天左右。在强制栽培中，在收获期开始时，“爱国者”和“韦茅斯”的果实产量高于其他品种。然而，在试验期内，‘北地’和‘锐蓝’的产量高于其他品种。由于收获期较晚，“阳光蓝”不适合强制栽培。强制栽培运果均价（3389公斤）高于其他季节。认为利用温室和水培系统对蓝莓进行强制栽培是在丘陵山区有发展前途的栽培方法。
We developed a sloped greenhouse and a hydroponics system suitable for use on sloping land. To use the greenhouse and the system effectively during the winter season, we investigated forcing culture of blueberry. We transplanted 15 cultivars of blueberry plants in containers filled with a peat-moss and supplied nutrient solution by the hydroponics system. Ten to 17 months after transplanting to the container, we investigated the death rate among plants of each cultivar. The death rate of plants was the highest in ‘Earliblue’. We considered that ‘Earliblue’ was unsuitable for the hydroponics system. In forcing culture, the plants experienced a term of cold temperature when placed outdoors in hilly and mountainous area (about 300 m above sea level) in Mikamo, Tokushima until 3 February, 2004. After 3 February, the plants were brought into a heated greenhouse near the field. Flowering of plants in forcing culture started at the end of February, which was 35–40 days earlier than flowering of plants under standard culture in Zentsuji, Kagawa. Harvesting from plants in forcing culture started at the end of April, which was about 35 days earlier than that from plants in standard culture. In forcing culture, at the beginning of harvesting term, fruit yields from ‘Patriot’ and ‘Weymouth’ were higher than those from other cultivar. However, for the experimental term, the yields from ‘Northland’ and ‘Sharpblue’ were higher than those from other cultivars. ‘Sunshineblue’ was unsuitable for forcing culture because of the late harvest period. The average price of shipped fruits from forcing culture was higher (¥3,389 kg) than that during other seasons. We supposed that forcing culture of blueberry using the greenhouse and the hydroponics system was promising culture method in hilly and mountainous areas.
