Postponing Pruning: New Zealand researchers delay grapevine pruning to boost yields and ensure consistency.

摘要

RSEARCHERS at the Malborough Wine Research Centre in New Zealand have spent the past several years evaluating the effects of delayed winter spur-pruning on Merlot grapevines, and they've gotten eye-popping results. Michael Trought and Adam Friend, whooriginally published their results in the Australian journal of Grape and Wine Research, did their evaluations in a commercial vineyard. The vines were spur-pruned, trained using vertical shoot positioning, drip-irrigated, and grafted to Kober 5BB rootstock.
