摘要

吃西瓜(Citrullus lanatus)是美国7月4日假期的传统组成部分;然而,在美国密苏里州为当地7月4日的市场种植西瓜需要在保护文化下提前开始生长季节(4月初),因为低温和冻结的风险。因此,研究了“黄娃娃”西瓜在低隧道(LT)和履带式高隧道(HT)下的生产情况,并通过边际分析对两种保护栽培的经济可行性进行了评估。在4月初播种,可以在目标市场日期前1到2周开始收获。此外,与旱地和裸地相比,高温处理下产量增加(Op)。本研究条件下的边际分析和从当地农贸市场获得的价格表明,与对照相比,高温处理的边际收益率为正。边际收益率敏感性研究表明,在高温处理和低温处理下,市场产量分别达到300-400磅和200-250磅/1200平方英尺是必要的。保护栽培在经济上可行,西瓜在当地农贸市场的价格高于0.75美元/磅和/或1.00美元/磅。因此,在保护栽培下生产西瓜是可能的,也有潜力为当地的7月4日市场提供西瓜。市场份额的增加和西瓜潜在的溢价可能会增加密苏里州中小型特种作物农民的可持续性。为了实现这一目标,有必要使用早期品种(70至80天成熟),在4月初在温室中种植移栽,并确保适当管理隧道,以保持有利的生长条件,防止冰冻温度并确保良好的授粉。

Watermelon Production under Protected Culture in Missouri, USA, to Reach the Local Fourth of July Market
Eating watermelon (Citrullus lanatus) is a traditional part of the Fourth of July holidays in the United States; however, growing watermelon in Missouri, USA for the local Fourth of July market requires an early growing season start (beginning of April) under protected culture because of low temperatures and the risk of freezing. Therefore, ‘Yellow Doll’ watermelon production was investigated under low tunnel (LT) and caterpillar high tunnel [HT (walk-in movable two-row tunnel)], and the economic feasibility was assessed by marginal analysis for both protected cultures. Planting in early April allowed harvest to start 1 to 2 weeks before the target market date. In addition, yield increased under HT in comparison with LT and open field (Op). Marginal analysis under the conditions of this study and prices obtained from local farmers’ markets showed a positive marginal rate of return for HT in comparison with the control Op. The marginal rate of return sensitivity study suggests that differences in marketable yield of 300–400 and 200–250 lb/1200 ft2 are necessary under HT and LT, respectively, for the protected culture to be economically feasible with watermelon prices above $0.75/lb and/or $1.00/lb as obtained in local farmers’ markets. Therefore, it is possible and there is potential to produce watermelon under protected culture for the local Fourth of July market. A gain in market share with potential premium prices for watermelon may increase the sustainability of small and medium-size specialty crop farmers in Missouri. To accomplish this, it is necessary to use early cultivars (70 to 80 days to maturity), plant in early April with transplants grown in greenhouses, and make sure to manage tunnels properly to maintain favorable growing conditions, protect against freezing temperatures and ensuring good pollination.
