Key Technical Points for Orchard Management After Grape Harvest
As China's science and technology become more and more advanced, planting techniques are also becoming more and more perfected, and grape cultivation has already been covered on a large scale. Grapes can be planted at almost any time of the year, which seems to be a good phenomenon for the market and for growers. However, with the development of grape cultivation techniques, problems also emerge one after another. For example, how to manage the orchard well after harvest is a problem that needs to be solved. Below, the editor will talk with everyone about how to manage the orchard after harvest.
1. Water and Fertilizer Management
After harvest, watering should be done in time, because watering can increase the growth rate of the tree body, quickly restore the nutrients and water lost during harvest, and speed up the tree's metabolism. It can also prevent grapes from cracking due to lack of water, but watering should not be excessive, because excess will cause the tree body to age and make it prone to pests and diseases. When topdressing, fertilizer should be applied according to the tree's fertilizer deficiency. Plots with sufficient base fertilizer may not need topdressing, and the same applies to tree bodies such as strong trees and large mature trees. When fertilizing, pay attention to the amount. Do not apply a large amount, to prevent the roots from being burned. Follow the principle of “apply more, but a small amount each time.”
2. Improve Air and Light Permeability
After several months of growth and fruiting and then harvest, the tree body is very tired, just like being pregnant for ten months, which causes great harm to a woman's body. The tree body should be cleared in time, the new buds of secondary shoots should be removed in time, old and aged branches that cannot bloom and bear fruit should be removed except for branches needed for vegetative growth, and the rest should also be completely removed. The main purpose of this is to prevent the orchard from being in a shaded and lightless environment, allow the fruiting branches of the fruit trees to have sufficient sunlight, increase the rate of flower bud differentiation, and reduce the loss of nutrients. Good ventilation and light transmission can provide a healthy growing environment for the tree body and roots.
3. Soil Plowing
Plowing the soil after harvest is very important. After harvest, the grass material in the orchard that preserves water and fertilizer should be removed in time, and the soil should be deeply plowed. The depth of plowing must not be less than 30 cm. Many friends worry that deep plowing will affect the roots, but this is not the case. After a year of growth, the tree roots have already grown into the deeper soil layers. Most of the roots in the surface layer are secondary roots and do not have much effect on grape growth, and deep plowing can also improve root vitality. However, attention should also be paid to the depth. It must not exceed 40 cm. Enhancing the permeability of the soil is beneficial to growth and flowering and fruiting in the coming year.
4. Pest and Disease Control
Pest and disease control is work that needs to be done throughout the entire growth process of grapes. It is just that the pests and diseases that occur after harvest are different from those during the growth period. The main pests and diseases that occur after harvest include brown spot disease and longhorn beetles, etc. These pests and diseases mainly harm the leaves of the tree body, and leaves are the key to ensuring nutrient accumulation. Therefore, we mainly need to do a good job in protecting the leaves and use various agents for control. For example, Bordeaux mixture and various insecticides, etc. Be careful not to carry out treatment in high-temperature and dry weather, to prevent harm to the tree body.
The above are the orchard management methods after grape harvest. Many friends generally neglect orchard management after harvest. Then it causes a great impact on flowering, fruiting and yield in the coming year. Although growing grapes has certain economic benefits, it requires enough time and patience to manage the orchard. Otherwise, all efforts will be wasted. That is all for today's introduction. If you want to learn more exciting information, please continue to follow us!
