Early Maturation Treatment and Management of Grapes in July
Let's introduce the knowledge about the early maturation treatment and management of grapes in July. Let’s learn about it together.
Early Maturation Treatment and Management of Grapes in July
In July, grapes in the open field enter the coloring maturity stage. Some grapes have already been harvested, but there has been a bit too much rain recently, especially the heavy rain in Southern China. Excessive moisture has a significant impact on the growth of grapes. At this time, improper management can easily lead to diseases and pests. So, how can we effectively prevent diseases and pests? Let's find out.
Grape Management in July
1. Drainage. Many gardens have imperfect drainage facilities, which can easily cause waterlogging in the grape garden. Therefore, it is necessary to do a good job of drainage after the rain to avoid water accumulation in the garden.
2. Remove withered leaves. There are many withered leaves and other sick bodies in the grape garden. To prevent bacterial growth, it is necessary to do a good job of disinfection.
3. Spraying control. During this period, whether after or before the rain, it is necessary to do a good job of spraying. Spraying has a fungicidal effect, which can effectively prevent and control downy mildew, (T-J) disease, white rot, and gray mold disease.
Grapes Ripening in July
1. Improve cultivation. Grapes are in the rainy season at this time, which can easily affect their formation and maturity. Therefore, the number of cultivations can play a role in promoting the early maturity of grapes. Bio-bacterial fertilizer or soil activators can be added during the cultivation process, which is beneficial for loosening the soil.
2. Plastic film mulch. Mulching with plastic film can increase the soil temperature, improve light conditions, increase the sugar content of grapes, and提前 color the fruit.
3. Bagging management. In low-temperature areas, cover with a film bag after the inflorescence extends. In the stage of young fruit shedding, the bottom of the bag can be torn open, changing the "bag" to a "tube" to accelerate maturity.
4. Promoting maturity by girdling. Girdling 3 centimeters below the fruiting branch node or the base of the mother branch at the initial stage of fruit maturity can promote maturity 5-7 days earlier.
In addition, during this period of grape growth, attention should also be paid to the growth of weak branches. Girdling is strictly prohibited. Moreover, methods to promote maturity include removing old leaves, spraying potassium fertilizer, and using regulators.
