1, wipe the bud
When the bud grows to 2-3 cm, the weak buds are wiped off, the buds sprouting, and the useless buds sprouting. For twin or triple buds, only one main bud is left. If the load is insufficient, the twin buds with inflorescence at the mother's branch can be found in a large space.
2, set the tip
It is carried out when it is 10-20 centimeters in length and can see inflorescence. For the varieties with low seed setting rate, large spikes, and vigorous growth, leave sufficient branches for the results. If the plant growth is too prosperous or weak, the result will be fewer branches and insufficient load. In addition to leaving all the resulting branches, a certain number of development branches should be left.
3, topping
The result is that the vine leaves 6-7 leaves topping, which can increase the rate of fruit set and promote the expansion of young fruit. Varieties, such as rose aromas, that are easy to drop and fall, should be picked up 3-5 days before flowering. For varieties with high fruit setting rate, they can take heart after the flowering.
4, to the auxiliary shoot
After topping the shoots, the shoots will germinate in large quantities, so control should be exercised to avoid consumption of nutrients. Inflorescence does not leave a shoot, the upper inflorescence in addition to the top of the remaining 1-2 a shoot, the rest are erased. The remaining apical leaves 4-6 leaves repeatedly topping.
5, inflorescence
For varieties with severe flowering and fruit drop, or with insufficient fertilizer and water, and the branches and vines are weak, 1/4 to 1/5 of the inflorescence may be removed 3-5 days before flowering to increase the fruit setting rate.
6, fruits and vegetables
The ear is very tight, with varieties of small grains and blue grains. Before the fruit enlargement, the grains increase the size of the fruit and maintain the order of the grains.
7, in addition to tendrils
The tendril not only consumes nutrients, but also twists around the ears and twigs to cause disorder in the shoots. Therefore, it must be removed in time. It is usually removed when it is picked up, removed, or tied.
8, tied new shoots
When the shoots reach 20-30 cm in diameter, the vines begin to grow. The growth of new shoots continues throughout the growing season, 3-4 times a year. When tying vines, they must not be cross-tied. Generally, they should be tied obliquely to ease the growth potential. The commonly used buckles are mostly horseshoe shaped. The tie material requires softness.
Summer garden grape trimming
The summer pruning of grapes is carried out during the growth period, mainly governing the relationship between the growth and results of the year, controlling the growth of new shoots, increasing the yield and quality, and significantly improving the ornamental effect of garden grapes. The following eight measures can be taken:
