Matters needing attention in grape harvest

Grape harvesting sounds like simply picking grapes from the tree, but in fact, there is more than one simple action in the process of grape harvesting and things to pay attention to. And different varieties are planted in different environments, the harvest time is different, the things to pay attention to are also different. Next, you can look for answers in the content instead of questions.

1. Harvest time

First of all, we need to determine what kind of grape we are currently growing, when it is mature, and whether the planting has changed in the current environment to calculate the approximate maturity. In general, the harvest is not mature enough and the taste is not good, but if it needs to be stored for a long time or transported for a long time, it can be harvested in the first half of the mature period. The use of physiological ripening can prevent corruption and deterioration in the process. The grapes that do not need to be transported are harvested at the right ripening period, which ensures that the taste reduces the acidity. Then there is the specific picking time, usually in low sunny weather, and after the dew on the grass dries, you can start picking until before 12:00, and then come out after three o'clock in the afternoon until evening, to avoid the strongest sun and avoid loss of water. The lower picking temperature at night can avoid oxidation consumption. Better to keep it fresh.

II. Harvesting methods

Usually hold the whole ear in one hand and cut it off one centimeter from the diseased branch with the other. After cutting, if there is bagging medicine to cut off the condom, check carefully whether there is diseased fruit or spikelet stalk, and if so, cut off the healthy part 1 centimeter in the whole place. Then gently put it into the picking box, generally a frame to about 2/3 is good, as far as possible staggered, do not align and squeeze. The bottom of the frame is usually laid, which can be covered with clean newspaper or clean straw or carton shell. To prevent injuries.

Matters needing attention

1. Do not cause mechanical damage to the tree or fruit during harvest.

two。 A slight yellowing of the pedicel is a sign of maturity, and too green can delay harvest.

3. Harvesting utensils must be soaked and disinfected with liquid medicine to avoid spreading diseases.

4. Do not spray pesticides in the first half of the month to avoid volatilization.

5. If there is water or other rotten leaves on the picked fruit, be sure to wipe it clean with a clean cloth before storing it.

6. In the case of delayed ripening due to other reasons, do not rush to harvest. You can wait until the fruit is visible and ripe. Don't harvest in rainy days and foggy days.

These are the aspects that should be paid attention to in grape harvesting, and we should generally pay attention to the time and mode of grape harvest. Then there are some small details, in order to preserve and transport the grapes after harvest without reducing the quality of the grapes, so we have to perfect the things we should pay attention to as much as possible. Only in this way can we reduce our losses.
