Changes in population levels of Meloidogyne hapla, M. incognita, Pratylenchus coffeae, and P. penetrans were studied in 12 strawberry fields in the Dahu region of Taiwan. Ten potential rotation crops and two cultural practices were evaluated for their effect on nematode populations and influence on strawberry yield. Rotation with rice or taro and the cultural practice of flooding and bare fallowing for four months were found to reduce nematode soil populations to two or fewer nematodes per 100 ml soil. Average strawberry yields increased between 2.4% to 6.3% following taro compared to the bare fallow treatment. Corn suppressed M. incognita and M. hapla populations and resulted in an increased in strawberry yield compared to bare fallow. Other phytopathogens also present in these fields limited taro as the rotation choice for nematode management. Results of this research and economic analysis of the input requirements for various rotation crops, corn and bare fallow were recommended as the most appropriate rotation strategies for nematode management in strawberry in this region.
在台湾大湖地区的12个草莓园中，研究了北方根结线虫、南方根结线虫、咖啡短体线虫和穿刺短体线虫种群数量的变化。评估了10种潜在的轮作作物和两种栽培措施对线虫种群的影响以及对草莓产量的影响。发现与水稻或芋头轮作以及淹水和裸地休耕4个月的栽培措施可将线虫土壤种群数量减少到每100毫升土壤中两个或更少的线虫。与裸地休耕处理相比，种植芋头后草莓平均产量提高了2.4%至6.3%。与裸地休耕相比，玉米抑制了南方根结线虫和北方根结线虫种群数量，并提高了草莓产量。这些田地中还存在的其他植物病原体限制了芋头作为线虫管理轮作选择的应用。本研究结果以及对各种轮作作物投入需求的经济分析表明，玉米和裸地休耕是该地区草莓线虫管理最合适的轮作策略。
