Embodiment Construction
[0021] The present invention can be better understood from the following examples. It is easy for those skilled in the art to understand that the content described in the embodiments is only for illustrating the present invention, and shall not and will not limit the present invention described in the claims.
[0022] Grafting method: According to actual production experience, when scion is handled during grafting, two slopes are cut along the front and rear sides of the bud at a distance of 0.5~1cm from the bottom bud, and a long slope with a length of 1.5~2.5 cm is cut on the back of the bud. Cut the inclined plane of 1~2 cm to ensure that the growth direction of the bud eye can grow outward during grafting. Cleaving starts in late April, and the rootstock is cut longitudinally at the edge of the rootstock's midline to a depth of 2 to 3 cm. When longitudinally cutting, the incision should be smooth and neat, and it should be cut with one knife. Grafting can start afterwards...

The invention discloses a method for changing varieties in a vineyard, and belongs to the technical field of agriculture. The method comprises the following steps of (1) collecting annual new grape branches in November of the first year, then carrying out stratification treatment, digging out the grape branches in the middle ten days of March of the second year, cutting the grape branches into scions with the lengths of 3-5 cm, and storing the scions at the temperature of 4-7 DEG C; (2) cutting back grape nursery stocks to be updated in November of the first year, topping a branch to serve as a stock, and removing other shoots; (3) cutting the scions obtained in the step (1) to be in a wedge shape in late April of the second year; (4) performing grafting in late April of the second year; and (5) timely removing new buds growing on the stock after grafting is completed, and then performing management according to a grape cultivation management mode. According to the method, the initial fruiting time of grapes can be greatly shortened, the cultivation cost is reduced, and the economic and social benefits of grape cultivation are greatly improved; and meanwhile, the processes of grape variety updating and structure optimization can be accelerated.
Description
technical field [0001] The invention belongs to the field of plant seedling cultivation, and in particular relates to a method for changing varieties in a vineyard. Background technique [0002] China's grape industry is developing rapidly, and the planting area is expanding day by day. At the same time, the replacement of grape varieties is also changing with the market demand. The 'Summer Black' grape has been one of the main varieties that have been popular for many years, and its cultivation area is very large, but in recent years, its price has dropped and its benefits have decreased. Therefore, grape variety replacement and structure optimization are problems to be solved urgently in the current grape production. 'Sunshine Rose' is a new variety with excellent quality. It is favored by consumers because of its beautiful fruit shape, high sugar content, good flavor and taste, and excellent quality. It has now become the main high-quality new variety in grape production...
