近两年来我区一些砂地栽植的巨峰葡萄出现缺硼症状,即果穗、果粒变小,无核;叶小、皱缩,呈淡绿色,并有均匀的黄色斑点;枝蔓节间短,新梢成熟度差等,使葡萄品质和产量受到很大影响。 In the past two years, some Kyoho grapes planted in some sandy areas of our region have the symptoms of boron deficiency, ie, the ears and fruit grains become smaller and have no nucleus; the leaves are small and wrinkled and are light green with uniform yellow spots; Poor maturity, etc., so that the quality and yield of grapes are greatly affected.
