How to manage grapes after harvest

At present, early maturing grapes have already been harvested, medium-maturing varieties will come to an end, and grape harvesting must pay attention to “post-harvest” management. If negligence management results in annual decline in production. If managed properly, it will not only reduce the damage that the cold winter brings to fruit trees, but also lay a foundation for the high yields in the coming year. There are comparisons to identify, I gave several agro-industry companies to do technical guidance, including a business owner, do not pay attention to post-harvest management, that the fruit is harvested, the orchard can give up management. As a result, the grape leaves fall early, the organic nutrient storage is low, the flower buds are poorly differentiated, the grapes are not germinated this year, and the spikes are small and the yield is low. Last year, 100,000 bags were bagged, only 60,000 were bagged this year, and the output fell by 40%. about. Our company attaches great importance to post-harvest management of grapes, and its output has increased year by year. Last year, our company had about 20,000 bags of grapes and 60,000 bags this year. Here I share with you the management methods of grapes after harvest:

Picking timely nutrition

Because the results of the consumption of a large number of nutrients, nutrition should be added as soon as possible after fruit picking, promote its early restoration of tree vigor, enhance the role of leaves to create carbohydrates, promote photosynthetic efficiency, extend the life of the leaves, to ensure that there is sufficient nutrient supply flower bud differentiation and Storage of tree nutrients. Spray 0.2% urea water + 0.2% potassium dihydrogen phosphate mixture once every 10 days and spray 2 or 3 times. In addition, organic fertilizer is applied once more, and 2000 kg of chicken manure and sheep manure are applied per acre, and trace element iron, zinc, and biological bacterial fertilizer are added.

Timely control of nutrient consumption

After the grapes are harvested, all growth points are removed, nutrient consumption is controlled, and nutrient backflow is promoted. Cut thin and weak branches, pests and branches, useless branches, overlord branches, and branches that have not been lignified.

Timely eradication of pathogens

The underground spraying to eradicate the source of the disease will cause the diseased fruit to fall on the ground when the fruit is harvested, which will cause the bacteria to remain in the soil and re-infect under the appropriate environmental conditions. Therefore, it is necessary to spray under the trees to eliminate the source of the disease. If the downy mild disease is severe, you can choose 40% Baobei Fumei Double, dilute the concentration 1000 to 1500 times; Gray mold can seriously choose 1000 times the liquid 40% pyrimethanil; serious acid rot can be used 80% of the necessary 400 Double spray the ground.

Shallow cultivation grass breathable moisturizing

After harvesting, the grapes were stepped down several times under the fruit trees, soil compaction, poor air permeability, and impeded root respiration. Under the tree weeding soil, remove the compaction, improve the permeability of the soil. It can also cover the grass under the tree. After the weeds rot, it can improve the granule structure of the soil and increase the organic matter content of the soil.
