Demand for Asian vegetables is rising rapidly due to changing demographics and increasing consumer awareness of their health benefits. However, growers are not familiar with growing these “foreign” crops due to insufficient technical information regarding suitable cultivars for different regions, production schedules, disease and pest susceptibility, and postharvest management. The objective of this study was to conduct trials in different production systems and climate regions to demonstrate the potential of growing Asian vegetables in Texas. We conducted preliminary trials of nine leafy greens in the open field, high tunnel, and greenhouse (container and hydroponic production) to explore the suitability and potential for year-round production. We also conducted field trials for warm season crops in the open field in different climate zones. Results indicated that for cool season leafy greens, open field production has a limited growing season, high tunnel has the potential to extend the growing season, while greenhouse may provide year-round production using soilless substrate container culture or hydroponic system. For warm season crops, early planting is recommended for high yield. Additional research is warranted in different regions to test more species and cultivars and optimize the production system of high-performing cultivars to maximize production and profitability.

德克萨斯州不同生产系统中代表性亚洲蔬菜的表现

由于人口结构的变化和消费者对其健康益处的认识不断提高，对亚洲蔬菜的需求正在迅速增长。然而，由于关于适合不同地区的栽培品种、生产计划、病虫害易感性以及收获后管理的技术信息不足，种植者并不熟悉种植这些“外国”作物。本研究的目的是在不同的生产系统和气候区域进行试验，以证明在德克萨斯州种植亚洲蔬菜的潜力。我们在空地、高隧道和温室（容器和水培生产）中对 9 种绿叶蔬菜进行了初步试验，以探索全年生产的适宜性和潜力。我们还在不同气候区的露天场地对暖季作物进行了田间试验。结果表明，对于凉季绿叶蔬菜，露天生产的生长季节有限，高隧道有延长生长季节的潜力，而温室可以使用无土基质容器培养或水培系统提供全年生产。对于暖季作物，建议早种以获得高产。需要在不同地区进行更多研究，以测试更多物种和品种，并优化高性能品种的生产系统，以最大限度地提高产量和盈利能力。建议早种以获得高产。需要在不同地区进行更多研究，以测试更多物种和品种，并优化高性能品种的生产系统，以最大限度地提高产量和盈利能力。建议早种以获得高产。需要在不同地区进行更多研究，以测试更多物种和品种，并优化高性能品种的生产系统，以最大限度地提高产量和盈利能力。
