When is the best time to pick grapes?

When picking grapes, wear white gloves and pick ripe fruit ears, holding the bottom of the grapes with one hand and cutting off the stems with scissors with the other hand to avoid damaging the trees.

Don't wait until the grapes are ripe to pick grapes, the grapes are very sour, and they are not tasty and have no sweet taste, so it depends on the time.

The grapes should be harvested between September and October, when the foliage stops thinning the fruit with sugar, making it the best time to pick grapes. It lasts until mid-October, but there are also late-maturing varieties that are harvested in November. When picking, it should be carried out after the dew is dry in the morning, its water content is relatively large, and it should be handled gently and lightly to avoid the fruit falling.

If deformed fruits are found, the diseased and insect fruits should be cut off in time.

Precautions for grape picking

You can't stay in the vineyard of the farm for a long time, because the grapes are all greenhouses, and the sheds are built with sheds all around, and the sheds are sealed, and it is very hot inside, and if you stay for a long time, you will be prone to heat stroke, because it is not a good thing to pick grapes and suffer from heat stroke, so you must control the time.

If you pick grapes in the farm, you should also pick grapes in a civilized manner, don't pick grapes indiscriminately inside, picking grapes hard will damage other people's gardens, so we must respect the fruits of other people's labor, and we can't destroy other people's labor at will, so we should be careful when picking grapes, because grape grains are also easy to fall, and it is a pity to drop grape grains on the ground.

Before looking for a job, you can look for information on the Urumqi website or other Xinjiang websites, and the animal husbandry industry does not recruit inexperienced short-term workers, and it is most suitable to pick cotton in Shihezi urban area and the surrounding regimental farms, but at the end of September and October.

<>1. If traditional bagging is generally used, grape varieties should be bagged 10-15 days before harvesting, which is conducive to improving light transmission and air permeability conditions, and helping the fruit chain to rise and color.

2. The traditional bagging can not remove the fruit collapse bag at one time, first open the bottom and prop it up, in the shape of an umbrella, and then remove all of it when waiting for harvesting.

3. Management after grape bag picking: after grape bag picking to before harvesting, the main thing is to color the berries, and after picking the bag, the old leaves, diseased leaves, and residual leaves around the fruit ear should be removed, and the excess branches and secondary tips should be cut off, and the leaves within 20cm around the fruit ear should be removed. Generally, the lower part of the shelf surface has a sieve-like light and shadow, and a part of it is retained to shade the fruit ears, and at the same time, the foliar fertilizer of the sea food is applied to prevent the fruit from being sunburned, and at the same time, the ears can be turned in time to ensure the light and promote the rapid coloring of the fruit ears.

What is the general ripening season of grapes? If it is a grape that is cultivated out of season, it can be done all year round. Below, we introduce the ripening time of grapes in the open field, as well as the harvesting time, method and precautions for grapes.

1. What season do grapes generally ripen?

Grapes generally ripen in late summer and early autumn. The grapes are harvested around the end of August and the beginning of September, but depending on the grape variety, the ripening time is different, so the exact time of harvest depends on the grape variety.

Generally, harvesting too early will cause the grapes to be not ripe enough and have a bad taste, but if they need to be stored for a long time or transported for a long time, they can be harvested half a month before the ripening period, so that physiological post-ripening can be used to prevent the grapes from spoiling.

If they do not need to be transported or stored, they can be harvested when the grapes are just ripe, which preserves the taste and reduces the acidity.

2. Time requirements for grape picking.

You can choose to do it in a sunny day, and when the dew dries, you can harvest it until 12 o'clock.

After 3 o'clock in the afternoon, straight or wide stools can also be picked in the evening, so that you can avoid strong sunlight, avoid water loss, and pick at night due to the lower temperature can avoid oxidation consumption, can better keep fresh.

3. The specific method of grape picking.

When picking grapes, you can hold the whole ear with one hand, hold scissors in the other hand and leave 1cm at the branch to cut it, if there is a bag after cutting, the bag must be removed, carefully check whether the grapes have diseased fruits, diseased spikelet stalks, if there are all to cut off.

The picked grapes should be put into the picking box, generally a shirt of 2 3 can be packed in a box, try to stagger the place, do not align and squeeze. The bottom of the frame should be padded, which can be padded with clean newspaper or clean straw or cardboard box shell.

4. Precautions for grape picking.

1. Before harvesting, a slight lack of water is the most suitable for picking, so that the grapes taste sweeter and the quality will be better. If there is rain, it must be drained in time and take measures to avoid falling fruits.

2. Grape fruits must be harvested when they reach physiological maturity, and grapes generally used for storage, such as red grapes, can be harvested when the sugar content reaches 16-19 °, and table grapes can be harvested when the sugar content of table grapes such as seedless white reaches 20-25 °.

<> when the grapes are in the harvest period, after the grapes are harvested, the butyrylhydrazide solution can be sprayed to inhibit the growth of the grape branches; It is also necessary to spray foliar fertilizer in time to restore tree vigor and enhance the photosynthesis ability of leaves. At the same time, it is necessary to cultivate and weed, and carry out deep ploughing, which can not only retain water and fertilizer, but also promote the growth of new roots and shoots.

1. Grape harvest management

1. Control the branches.

After the grapes are harvested, the vine branches continue to spread and grow, depleting the nutrients of the tree. In order to prevent the grape branches from absorbing nutrients, a sprayable butyrylhydrazide solution inhibits its vigorous growth. At the same time, it is necessary to prune branches reasonably, leave more thick branches, and overly dense branches, weak branches, and diseased and insect branches should be thinned out as soon as possible.

2. Fertilization. After harvesting grapes, foliar fertilizer should be sprayed in time to restore the tree's potential and enhance the photosynthesis ability of the leaves. Every 10 days or so, a mixture of high-nitrogen water-soluble fertilizer and dipotassium phosphate can be sprayed.

It is necessary to apply a base fertilizer in autumn, and an acre of grape land needs to prepare more than 2,000 kg of soil miscellaneous fertilizer, circle fertilizer, compost and other organic fertilizers, and add 20kg of high phosphorus compound fertilizer, mix and ditch the application, and cover the soil in time after application.

3. Cultivating loose soil.

After harvesting the grapes, they should be cultivated and weeded in time, and deep ploughing should be carried out, which can maintain a certain degree of air permeability, water and fertilizer retention, and promote the growth of new roots and shoots.

4. Disease prevention and removal.

After picking grapes, 500 times of 50% gram wettable powder, 500 times of 65% zeb wettable powder, 1000 times of 70% methyl tobuzin wettable powder can be sprayed every 10 days, and other agents need to be sprayed alternately.

5. Reduce damage.

After harvesting the grapes, try not to cut off a lot of side shoots and old leaves, which will affect the growth and fruiting of the plants in the coming year. Generally, after harvesting, you can not pick the leaves, remove the tips less, and try to retain the strong branches and leaves.

6. Tidy up the orchard.

When harvesting grapes, the orchard will become dirty due to various operations, so it is necessary to clean the orchard in time after harvesting.

2. When is the season for harvesting and harvesting grapes?

1. When the grapes can be harvested.

Grapes can be harvested at the end of August and the beginning of September, but the grapes ripen at different times depending on the variety, so the specific harvest time of the grapes needs to be determined according to the grape variety.

2. Precautions when harvesting grapes.

1) When harvesting grapes, do not damage the trunk artificially.

2) When harvesting grapes, if the stems are too green, it is not ripe yet, and the harvest can be delayed for a while.

3) Supplies for harvesting grapes need to be soaked in medicinal solution before use.

4) When the grapes are about to be harvested, do not spray chemical fertilizers.

5) There should be no water or rotten leaves on the grapes, and the grapes should be wiped clean with a clean cloth before storage.

6) Generally, grapes should not be harvested on rainy and foggy days.

1. Picking method: Picking fresh table grapes should be light, holding scissors in one hand, pinching the fruit stalk with the other hand, and leaving centimeters to cut the ear stalk.

2. Varieties with short spikes or coarser spikes can be gently held with one hand, cut with a knife in the other hand, and gently placed in the fruit basket. The fruit basket should be shallow and can hold layers. Be careful not to scratch the fruit with scissors or rub the powder with your hands.

3. When manually picking wine grapes, the diseased and insect fruits should be removed, and the stool should be directly loaded into the transport box.

1. Picking method Picking table grapes should be light, hold scissors in one hand, pinch the ear stalk with the other hand, and leave the coarse sparrow cm spike stalk to cut the potato quietly.

2. Varieties with short spikes or large spikes can be gently held with one hand, cut with a knife in the other hand, and gently placed in the fruit basket. The fruit basket should be shallow and can hold layers. Be careful not to scratch the fruit with scissors or rub the powder with your hands.

3. When picking wine grapes, the manual stool picks the wine grapes and removes the diseased and insect fruits and puts them directly into the transport box.

Time of grape planting.

Grapes are best planted in autumn, allowing for early fruiting and high yields. Moreover, there is no need to delay the emergence of seedlings in spring, and the germination time is 20-30 days earlier than spring sowing.

Grape origin. Grapes are grape plants, mainly produced in the Northeast, Bohai Bay, Shacheng, Qingxu, Yinchuan and other sunny places.

Viticulture methods.

Grapes are perennial vine fruit trees. Choose high, fertile, deep sandy loam soil for planting. A frame needs to be set up to maintain a certain space and fruit shape.

It is advisable to graft seedlings with complete root system for 1-2 years. In planting, it is necessary to improve ventilation and light transmission, insist on large fertilizer and suitable water, and do not irrigate too frequently.

Key points of viticulture management.

1.Seedling management: After the grape seedlings are planted, they should be reasonably watered, fertilized and supplemented with nutrients according to the degree of drought.

Nitrogen fertilizer is the main fertilizer, combined with the use of organic fertilizer to bridge the stuffiness, timely weeding, to avoid damage to plant roots. 2.Growth Period Management:

Grapes are mainly nitrogen-based fertilizers, which need to be combined with phosphorus and potassium fertilizers. At this time, it is necessary to set up a scaffold and pull it to the scaffold to climb and grow, and at the same time pick the pits reasonably and water them according to the water demand. 3.

Fruit setting stage management: Nitrogen fertilizer should be applied in combination with phosphorus and potassium fertilizer in spring budding stage, and phosphorus and potassium fertilizer should be applied when grape seedlings bloom. It is necessary to reasonably thin flowers and fruits to reduce physiological fruit drop.

Finally, when the grapes grow to the size of soybeans, apply strong fruit fertilizer to achieve the purpose of strong fruit. 4.Post-harvest management:

After the grapes are harvested, the fields should be cleaned and disinfected to reduce pests and diseases, and the vines should be pruned like old branches to control pests and diseases. After composting, prepare for the next year's high yields.

Time of grape planting.

Grapes are best planted in the spring about half a month before most crops bud break, around March-April, but there are also September-Octobers. If planted in late March to early April in northern China, planted in autumn, it is best planted in September to October.

Viticulture methods and key points.

1. Soil. Grapes prefer sandy loam soils with good air permeability, so the choice of soil is very important, and the organic matter should be more than 2%, which helps to improve the yield and quality of grapes.

2. Planting. Grapes are generally planted in autumn with a distance of 2-3m between each plant. Before planting, cut the roots of the seedlings into about 20cm and soak them all day.

When planting, stretch the roots and then cover with soil. After planting, water them thoroughly, it is best to cover them with a thin plastic film. When planting, do not do not apply fertilizer directly, otherwise you are in danger of burning the roots.

Precautions for viticulture.

The first fertilizer is usually applied when the seedlings are sown and the second fertilizer is applied during the fruiting period of the grapes. At this time, it usually takes about three times for the grapes to bloom from bud break to flowering. It should be noted that the flowering period should be watered less often, and the fruiting period should vary according to the rainfall at that time.
