Southern highbush blueberry (SHB) production is continuing to expand worldwide. Innovative horticulture practices including container-based cultivation, evergreen management, high-density planting, and high-tunnel production have been explored to maximize the productivity and profitability of SHB production. However, there is a lack of information on the feasibility of integration of all these practices to establish an intensive production system in Florida. We aimed to test and optimize this intensive system by evaluating container size, substrate composition, and genotype. Two container sizes (50.5 L and 40.4 L), five different combinations of pine bark, coco coir, and perlite, and five SHB genotypes were tested in this study. Plant vegetative growth, yield, and berry quality were measured for two years. There were no impacts of substrate composition and container size on vegetative or reproductive growth during the two-year production period studied. Plant height and canopy width varied among genotypes due to their canopy architecture. Yields of each genotype ranged from 1.0 kg/bush to 2.5 kg/bush in the first year and ranged from 0.4 kg/bush to 2.1 kg/bush in the second year. Significant differences in the performance of five genotypes tested in this study indicated that is necessary to breed cultivars specifically for this intensive system.

南部高丛蓝莓 (SHB) 的产量在全球范围内继续扩大。已经探索了创新的园艺实践，包括基于容器的种植、常绿管理、高密度种植和高隧道生产，以最大限度地提高 SHB 生产的生产力和盈利能力。然而，缺乏关于整合所有这些实践以在佛罗里达州建立集约化生产系统的可行性的信息。我们旨在通过评估容器大小、底物组成和基因型来测试和优化这个密集的系统。本研究测试了两种容器尺寸（50.5 升和 40.4 升），松树皮、椰壳和珍珠岩的五种不同组合，以及五种 SHB 基因型。对植物的营养生长、产量和浆果质量进行了两年的测量。在所研究的两年生产期间，基质成分和容器大小对营养或生殖生长没有影响。由于其冠层结构，不同基因型的植物高度和冠层宽度不同。第一年每个基因型的产量从1.0公斤/灌木到2.5公斤/灌木，第二年从0.4公斤/灌木到2.1公斤/灌木。本研究中测试的五种基因型的性能存在显着差异，表明有必要专门为这种集约化系统培育品种。第二年1公斤/丛。本研究中测试的五种基因型的性能存在显着差异，表明有必要专门为这种集约化系统培育品种。第二年1公斤/丛。本研究中测试的五种基因型的性能存在显着差异，表明有必要专门为这种集约化系统培育品种。
