一、防寒时期各地气候条件差异,防寒时期不尽相同。防寒培土不能过早,因为外界气温较高附着在葡萄枝蔓上的霉菌尚在活动,土壤中温湿度适合而大量繁殖破坏枝芽,也称烧芽。而且葡萄枝芽需经抗寒锻炼,进入休眠期,增强抗寒能力。但过晚防寒,土冻成块,培土不严透风,葡萄易遭冻
First, the climatic conditions during the cold period differences, cold period is not the same. Cold-proof soil can not be premature, because the outside temperature is higher attached to the grape vine on the mold is still active, the temperature and humidity in the soil suitable for large-scale breeding and destruction of branches, also known as burning buds. And the grape bud buds need cold exercise, into the dormant period, enhance cold ability. But too late cold, frozen soil into blocks, soil is not strict ventilation, easy to freeze the grape
