How to apply foliar fertilizer to grapevines? These techniques must be mastered
Spraying grapevines with foliar fertilizer gives the leaves a wide fertilizer-receiving surface, acts quickly, saves labor and fertilizer, and is a commonly used fertilization method for grapes. Generally, absorption begins 2 hours after the fertilizer solution is sprayed, and 88% of a urea solution can be absorbed within 24 hours after spraying. Spraying 0.2%-0.3% urea solution mixed with 0.1% boric acid or borax or multi-element boron fertilizer during the flowering period can...

Practical experience in achieving stable yields through the renewal of old grapevines
Practical experience in renewing old grapevines for stable yields. Traditional renewal of old vines involves cutting the old vines back hard so that they send out new shoots, with no yield in that year. At the grape experimental garden of the HAIYAN COUNTY INSTITUTE OF AGRICULTURAL SCIENCES in Zhejiang, on 16-year-old and 13-year-old vines of Fujiminori and Zui Jinxiang grapes...
