"野生草莓起源于欧洲、美洲和亚洲，现代大果型栽培草莓则起源于法国。1915年，中国最早引入的现代草莓，是俄罗斯侨民自莫斯科引入黑龙江亮子坡种植的“维多利亚”品种。中国范围内均有草莓的商业化生产，其草莓栽培面积和产量均居世界第一位。草莓根系较浅，具有喜光耐阴、喜水怕涝等特点。 [6] \n" +
"草莓具有较高的营养价值、医疗价值和生态价值。草莓浆果芳香多汁，营养丰富，素有“水果皇后”的美称，又是果树中上市最早的鲜果，素有“早春第一果”的美称。草莓含有较高的维生素、钙、磷、铁等营养物质， [6] 且草莓中含有众多活性物质，可清凉止渴，健胃消食的功效，具有一定的医疗价值，在书籍如《台湾药用植物志》有体现。 [7] 草莓也可作为观赏、绿化植物，已成为中国西部地区农民脱贫致富的首选作物。");
