How to Manage Newly Planted Grapes
Sharing content on how to manage newly planted grapes and grape flowering management techniques in the field of green plants and flowers. Next, the site editor will introduce to the netizens.
Grapes should be fertilized during the flowering period, and boracic acid solution should be sprayed before flowering. Controlling the day and night temperatures can promote flowering, with 28°C during the day and 16-18°C at night. Keep the air humidity at 50%. Thin the inflorescences according to the growth state of the branches, removing unnecessary inflorescences to save nutrients. Let's learn more in detail.
1. Appropriate Topdressing
Before flowering, spray a 0.2%-0.3% borax solution or boric acid solution on the leaves, which can promote the elongation of the pollen tube and increase the fruit setting rate. Appropriate supplementation of high-phosphorus fertilizer can also promote flowering. Pinching and pruning the branches according to the growth of the fruit tree can also reduce nutrient consumption.
2. Controlling Temperature
Controlling the temperature can improve the germination rate of pollen. Keep the daytime temperature at 28°C and the nighttime temperature at 16-18°C. A relatively warm environment is conducive to flowering.
3. Controlling Humidity
No watering during the flowering period, controlling the environmental humidity at 50% is sufficient. Watering once before flowering is enough to maintain soil moisture. Watering during flowering will increase soil humidity and reduce soil temperature, which is not conducive to nutrient absorption. Keep the orchard well-ventilated, ensuring humidity while avoiding dampness and properly ventilating.
4. Thinning Inflorescences
About 10 days before flowering, you can start thinning inflorescences, pruning according to the growth state of the inflorescences on the branches. Each fruiting branch should first retain at least 2 inflorescences, weak inflorescences should be cut off, and weak fruiting branches may not need to retain inflorescences, while medium-strong branches should retain 1 inflorescence. While pruning the inflorescences, deal with the residual branches and bad leaves to improve the light transmission of the grape trellis and increase ventilation.
5. Pest and Disease Control
For pests such as thrips, scale insects, green stink bugs, and leafhoppers, you can use avermectin 5-7 days before flowering for control. For downy mildew, black spot disease, and gray mold, spray pyridaben plus carbendazim. Be cautious with chemicals from fruit setting to bagging to avoid leaving traces on the fruit surface.
The above is a specific introduction to how to manage newly planted grapes and grape flowering management techniques, hoping to bring some flower knowledge to green plant enthusiasts.
