摘要:通过小区试验研究了不同比例的氮、钾肥配施对草莓产量和品质的影响。结果表明:对上海浦东新
区栽种的‘章姬’草莓而言,最佳施肥处理组合为施氮量,⑹┘亓篛 kghm2

提升作用,但高的施钾量也增加了草莓的酸度。在一定范围内,增加施氮量明显提升了评价草莓品质的各项指
标,但过高的施氮量也导致草莓含糖量和固酸比降低,影响草莓品质。

年以上的历史,当前种植的草莓品种以‘章姬’为主,主要采用大棚设施栽培。这种栽培方式不仅延长
了鲜果的供应期,而且产量高,经济效益好,其种植面积在当地逐年增加。但因果农施肥品种单一,方式
不合理,导致草莓品质逐年下降,口感差,不仅影响了经济效益,而且连年种植造成大棚土壤结构变差,次
