英国皇家园艺学会建议停种花椰菜 应对创纪录高温

英国皇家园艺学会（RHS）因极端高温天气建议家庭园丁停止种植花椰菜及其他芜菁类蔬菜1。今年英国夏季气温创下有记录以来的最高值，8月13日伦敦基尤花园温度达到38.1℃1，英国6月也成为自1884年有记录以来最热的6月1。这种极端天气导致花椰菜等蔬菜因缺水和高温无法正常生长1。

RHS首席园艺师盖伊·巴特表示："花椰菜及其芜菁类亲属受到最严重影响，随着今后夏季可能继续这种模式，用同样美味营养的替代品取代它们将节省宝贵的浇水资源"1。该学会建议园丁改种番茄、秋葵、甜椒和黄瓜等耐热蔬菜1。英国预计今年大多数芜菁类蔬菜产量将很差，可能是创纪录最差年份之一1。

The Royal Horticultural Society (RHS) has advised home gardeners to stop growing cauliflower and other brassica vegetables in response to record-breaking summer heat and climate change impacts 1. Britain experienced its hottest summer on record this year, with London's Kew Gardens reaching 38.1°C (100.1°F) on August 13, and June marking the warmest June since records began in 1884 1. These extreme temperatures have prevented brassicas from growing properly due to water scarcity and heat stress 1.

The RHS's chief horticulturist, Guy Barter, emphasized the severity of the situation, stating: "Cauliflower and its brassica relatives are suffering the worst, and as future summers may continue in this pattern, replacing them with equally delicious and nutritious alternatives would save precious watering resources" 1. To help gardeners adapt, the RHS recommends switching to heat-tolerant varieties including tomatoes, okra, sweet peppers, and cucumbers 1. Most brassica vegetables are expected to produce poor yields across the UK this year, potentially marking one of the worst seasons on record 1.
