How to Increase the Fruiting Rate of Jufeng Grapes
A comprehensive explanation of how to increase the fruiting rate of Jufeng grapes in the aspect of green plants and flowers, with specific details as follows:
How to Increase the Fruiting Rate of Jufeng Grapes
Jufeng grapes are a hybrid species from Europe and the United States. They have strong adaptability and disease resistance. It is one of the main grape varieties. Its planting area spans the world. However, many fruit farmers say that the fruiting rate of Jufeng grapes is low. So, how can we increase the fruiting rate of Jufeng grapes? Let's find out.
Factors Affecting the Fruiting Rate of Jufeng Grapes
There are many factors that affect the fruiting rate of Jufeng grapes. The first is temperature. The suitable temperature for the flowering period of Jufeng grapes is 26-30°C. If the temperature exceeds 30°C for a long time, it can lead to continuous severe flower drop and a decrease in fruiting rate. The more lush the tree, the more severe the flower drop. Additionally, the denser the branches, the easier the fruit drop. Pruning after flowering can also cause fruit drop. Gray mold and brown spot diseases can also affect the fruiting rate. Excessively moist soil can also lead to severe fruit drop. The reasons for the low fruiting rate are multifaceted.
How to Increase the Fruiting Rate
1. Control the growth of the tree
If the length of new shoots exceeds 80cm before flowering, the fruiting rate is relatively low. Additionally, during the growth of new shoots, it is necessary to control fertilization and water supply to prevent excessive growth of new shoots. After fruiting, apply compound fertilizer and potassium sulfate to promote fruit growth and reduce fruit drop.
2. Thin from the heart
This can be done about a week after flowering to concentrate nutrition and inflorescence, which is beneficial for fruiting. When thinning, attention should be paid to the method. Generally, for weak inflorescences, 5-6 leaves are left, and for vigorous inflorescences, 3-5 leaves are left.
3. Spray Zhu Zhuang Su
About a week into the flowering period, spraying Zhu Zhuang Su can significantly increase the fruiting rate. The commonly used Zhu Zhuang Su is Jia Gu Su water, usually 15 mg per bottle mixed with 15 liters of water, and the concentration of Changshi Wang can be increased to 12 liters of water per bottle.
4. Control production
Thinning flowers and fruits can reduce the plant's consumption of nutrients, thereby avoiding the phenomenon of premature aging or even the balance between vegetative growth and reproductive growth. Controlling yield can significantly improve the fruiting rate and quality of grapes. The general yield is about 3500 kg per mu. Each cluster of fruits needs to leave 20-25 effective leaves, and no sub-branch leaves are left above 3-5 leaves on the cluster, with the sub-branch leaves starting from 5 leaves above, and each cluster has about 40 berries.
The above methods on how to increase the fruiting rate of Jufeng grapes, I hope they can help you.
