Compared to the small experiences of grape harvesting for most people, the editor of this site will introduce to everyone next.
Points to Consider When Harvesting Grapes
Grape picking is a simple method of picking grapes from trees, but in reality, the process of grape picking and the things to pay attention to are not just such a simple action. Moreover, different varieties planted in different environments have different harvest times and different things to pay attention to. Next, you can turn to the content to get the answer, not the question.
Hharvest Time
Firstly, we need to determine what kind of grapes we are planting, when they ripen, and whether there have been changes in the current environment to calculate the approximate ripeness. Generally speaking, harvesting too early is not ripe enough and the taste is not good. However, if long-term storage or transportation is needed, harvesting can be done half a month before maturity, using physiological maturation to prevent spoilage during the process. Grapes that do not need to be transported should be harvested at the appropriate maturity stage to ensure taste and reduce acidity. Then there is the specific pickup time. Generally, it can be picked from after the dew dries to before 12 p.m. when the sunlight is not too strong, and from 3 p.m. to dusk, to avoid the strongest sunlight and water loss. Picking at night when the temperature is low can prevent oxidation and save better.
Harvesting Method
Generally, one hand holds the whole cluster, and the other hand cuts it about one centimeter away from the diseased branch. After cutting, if there is a bagged medicine, cut off the cap, and carefully check for diseased fruits or diseased peduncles. If any, cut it about one centimeter away from the healthy part. Then gently put it into the picking frame. Generally, a frame should be filled to about two-thirds. Try to place it alternately, not aligned and squeezed. The bottom of the box is usually filled with clean newspaper or clean straw or carton shell to prevent injury.
Precautions
1. Trees or fruits should not be damaged artificially.
2. Slightly yellow fruit stems are a sign of maturity, and too clean can delay the harvest.
3. Harvesting tools must be soaked in a disinfectant to avoid the spread of diseases.
4. Pesticides should not be sprayed in the first half of the month to avoid incomplete evaporation.
5. When picking fruits with water or other attached rotting leaves, be sure to wipe them with a clean cloth before storing.
6. When the maturity period is delayed for other reasons, do not rush to harvest. You can wait until the fruit ripens. Do not harvest in the rain or fog.
The above are the aspects to be considered when harvesting grapes, generally paying attention to the harvest time. There are also some small details. In order to save and transport grapes after harvest without reducing the quality of the grapes themselves, we must try our best to perfect the things we should pay attention to. Only in this way can we reduce losses.
The above is a comprehensive explanation of the precautions for grape harvesting, hoping it can help you.
