北卡罗来纳州正在经历草莓产业的振兴，这是由于采用了塑料栽培技术和加州栽培品种钱德勒，它产生了良好的产量和果实质量的黑色塑料覆盖。有了这个系统，浆果可以在种植后7到8个月内收获。在大多数年份，春季收获季节可持续长达6周。北卡罗来纳州的草莓塑料栽培种植者通常的产量为17，000至18，000磅/英亩（19，054至20，174公斤·公顷）。该系统的现金费用约为4345美元/英亩（10736美元/公顷）。该系统需要一个用于开花和花蕾防霜/防冻的高架洒水系统，以及用于在开花前、开花和结果期提供水和肥料的滴灌系统。桑迪壤土和粘壤土是用造床机造床的理想土壤。通常，33%的N、50%的K和所有的P在种植前施用，剩余的N和K通过滴灌系统施用。与塑料栽培系统相关的问题包括较高的初始投资相对于垫行生产，只有一个结果季节是可能的炭疽病易感的“钱德勒”在美国东南部。
North Carolina is experiencing a revitalization of the strawberry industry due to the adoption of plasticulture technologies and the California cultivar Chandler, which produces excellent yields and fruit quality on black plastic mulch. With this system, berries can be harvested in just 7 to 8 months after planting. The spring harvest season can last up to 6 weeks in most years. Strawberry plasticulture growers in North Carolina typically experience yields of 17,000 to 18,000 lb/acre (19,054 to 20,174 kg·ha). Cash expenses for the system are about $4345/acre ($l0,736/ha). The system requires both an overhead sprinkler system for blossom and bud frost/freeze protection, and drip irrigation for supplying water and fertilizer in the prebloom, bloom, and fruiting periods. Sandy loam and clay loam soils are ideal for forming the lo-inch-high (25.4-cm) beds with bedding machines. Usually, 33% of the N, 50% of the K, and all of the P is applied preplant, with the remaining N and K applied through the drip-irrigation system. Problems associated with the plasticulture system include higher initial investment relative to matted-row production, and only one fruiting season is possible with the anthracnose-susceptible ‘Chandler’ in the southeastern United States.
