Management of grape orchard after harvest

With the development of science and technology in our country, the planting technology is becoming more and more perfect, and the cultivation of grape has been covered on a large scale. Grapes can be grown almost at any time of the year, which seems to be a good sign for markets and growers. However, with the development of grape planting technology, problems emerge one after another. For example, how to manage the orchard after harvest is a problem that needs to be solved. Next, the editor will talk to you about how to manage the orchard after harvest.

1. Water and fertilizer management

It should be watered in time after harvest, because watering can improve the growth rate of the tree, quickly restore the nutrients and water lost during harvest, and accelerate the metabolism of the tree. It can also prevent grapes from cracking due to lack of water, but watering should not be excessive, because excessive watering will make the trees aging and prone to diseases and insect pests. Topdressing needs to be fertilized according to the lack of fertilizer in the tree body, and the land with sufficient base fertilizer can be used without topdressing, as well as strong trees, adult trees and so on. Pay attention to the amount of fertilizer, do not apply a large amount, to prevent the root from being burned out, follow the principle of "more and a small amount".

2. Improve permeability

After several months of growth and fruit harvest, it is very tiring for the tree, which is equivalent to being pregnant in October, which is very harmful to women's body. To dredge the tree in time, wipe off the new buds of the secondary shoots in time, remove the aged branches that cannot blossom and bear fruit, remove the branches that need to be used as vegetative growth, and remove all the rest. The main purpose of this is to prevent the orchard from being in a shady environment, so that the fruit branches of fruit trees have enough sunlight, improve the rate of flower bud differentiation and reduce nutrient loss. Good ventilation and light transmission can provide a healthy growth environment for trees and roots.

3. Soil ploughing

Ploughing the soil after harvest is very important. After harvest, the forage of water and fertilizer conservation in the orchard should be removed in time, and the soil should be deeply ploughed. The depth of ploughing should not be less than 30 centimeters, and many friends are worried that deep ploughing will have an impact on the roots, but in fact, after a year of growth, the roots have grown into the underlying soil. The surface roots are mostly accessory roots, which do not have much effect on the growth of grapes, and deep ploughing can also improve the vitality of the roots. But also need to pay attention to the depth, not more than 40 cm, enhance the permeability of the soil, conducive to the growth and flowering and fruiting in the coming year.

4. Pest control

Pest control is a work that needs to be done in the whole process of grape growth. It is just that the diseases and insect pests produced after harvest are different from those when they are born, and the diseases and insect pests that will be produced after harvest are mainly brown spot and longicorn beetles. These diseases and insect pests are mainly harmful to the leaves of trees, but leaves are the key to ensure the accumulation of nutrients. Therefore, we should mainly do a good job in the protection of leaves and use a variety of chemicals for prevention and control. For example, Bordeaux liquid and a variety of pesticides, be careful not to carry out in hot and dry weather to prevent damage to the tree.

The above is the orchard management method after the grape harvest, and many friends generally ignore the orchard management after harvest. Then it has a great impact on the 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, it will be in vain. That's all for today's introduction. If you want to know more wonderful information, please continue to follow us!
