Abstract

The majority of strawberry (Fragaria ×ananassa) production in Florida, USA, uses bare-root transplants that require large volumes of water via sprinkler irrigation for establishment. Although plug transplants can be established without sprinkler irrigation, they generally are more than double the cost of bare-root transplants. We hypothesized that the use of early-planted (September) plug transplants on white-on-black mulch without impact sprinkler irrigation (WP system) would be more profitable and conserve water compared with the typical grower standard practice of black plastic mulch and bare-root transplants planted in mid-October that were established using impact sprinkler irrigation for heat mitigation for 12 d after transplanting (BB system). ‘Florida Radiance’ plug transplants and bare-root transplants were used in the 2-year study that was conducted at Citra and Balm, FL, USA. Water use and early and total strawberry yield of the two systems were compared. Water use in both locations was lower with the WP system than the BB system. Early yield was higher by 683 and 346 8-lb flats/acre with the WP system at Citra and Balm, respectively, compared with the BB system. The total marketable yield with the WP system was 2062 flats/acre and 1917 flats/acre greater at Citra and Balm, respectively, than with the BB system. Partial budget analysis indicated that the WP system at Citra increased the net profit by $14,657/acre, whereas a net profit of $13,765/acre was obtained at Balm. These results will inform decision-making about cropping system modification that can be adopted by Florida strawberry growers to considerably reduce water use in an economically feasible manner.

佛罗里达州提高早期产量和节水的草莓种植系统设计及其经济效果
美国佛罗里达州的大部分草莓(Fragaria ×ananassa)生产采用裸根移栽,需要通过喷灌大量的水来建立。虽然不需要喷灌也可以种植插秧,但它们的成本通常是裸根插秧的两倍多。我们假设,与典型的种植者标准做法(黑色塑料薄膜覆盖和10月中旬种植的裸根移栽,移栽后使用冲击喷灌(BB系统)缓解12 d的热量)相比,在白对黑覆盖上使用早播(9月)插拔移栽,不使用冲击喷灌(WP系统),将更有效益和节约用水。在美国佛罗里达州Citra and Balm进行的为期2年的研究中,使用了“Florida Radiance”插头移植和裸根移植。比较了两种栽培体系的水分利用、草莓早产量和总产量。在这两个地点,WP系统的用水量都低于BB系统。与BB系统相比,在Citra和Balm, WP系统的早期产量分别提高了683和346个8磅单位/英亩。WP系统的总可售产量在Citra和Balm分别比BB系统高2062单位/英亩和1917单位/英亩。部分预算分析表明,Citra的WP系统使净利润增加了14,657美元/英亩,而Balm的净利润为13,765美元/英亩。这些结果将为佛罗里达州草莓种植者采用的种植系统修改决策提供信息,从而以经济可行的方式大大减少用水量。
