Grape secondary results have methods
The grape is twice a year. On the basis of strengthening the nutrition of the tree, the grape flower bud differentiation time is short and fast, so that the growth of the fruit tree or the young shoots of the young shoots and the secondary shoots of the winter buds . This method has a certain application in production in recent years, and there are two methods:
Inspire the winter buds in the same year, the secondary fruit is 7 to 10 days before flowering. When 13 to 15 leaves grow on the vegetative shoots, pick the hearts at 8 to 10 leaves, and remove all the secondary shoots to stimulate the germination of winter buds; or Leave 8 to 10 leaves above the resulting node, and remove the above part, and remove the secondary tip from the base. At the same time, the main tip is strongly selected to stimulate the germination of winter buds.
Inducing the buds of the secondary buds 15 to 20 days before the flowering of the main shoots, above the main shoots, the nodes of the summer buds have not yet germinated, the main shoots are topped, and the buds that have sprouted in the lower part are all erased. To concentrate the nutrients on the top buds that have not yet germinated to obtain better quality inflorescences. For example, when there are no inflorescences on the secondary shoots of summer buds, when 4 to 5 leaves are to be spread, 2 to 3 leaves are topped, and the secondary shoots of summer buds are used. General Jufeng and other varieties use this method to achieve good results.
