Apple bagging methods and steps, apple bagging techniques

The apple bagging method and steps are as follows:

Tools Raw materials: high-quality fruit bags.

1. Choose high-quality fruit bags, in order to ensure fruit quality, you can pick deformed fruits, diseased fruits and densely grown fruits. Stretch the bag open. Of course, gestures can be chosen at will. Ventilation holes are kept at the bottom of the fruit bag.

2. Pay attention to the opening of the fruit bag, cross the front and back, and wrap tightly. The stalk is placed in the gap between the mouth of the bag. Remember, there should be no gaps between the stalk and the mouth of the bag.

3. Dock on both sides and pinch hard.

4. Pinch the middle position of the left side with the left hand, move the right hand to the right side and fold back and pinch tightly. Pinch where your right hand is folded back, and your left hand is also folded back and pinched.

5. Fold the left and right sides to the rear and pinch hard. The key to this step is how to tighten the mouth of the bag, and now it is used to tighten it by folding back on both sides and pinching it.

The apple bagging method and steps are as follows:1. Open the mouth of the bag first, enter the bag with your hand to open the air hole, and hold the bottom of the bag with the other hand to make the bag into a lantern shape.

2. Hold the middle two sides of the bag with both hands, so that the fruit can safely enter the bag and lift up, so that the fruit stalk is sandwiched at the bottom of the middle crack.

3. Press one side with iron wire on the other side, fold and press the crack tightly and combine it with the front and pinch it with your right hand.

4. The left hand will catch the side of the wire, press the wire backwards, the upper mouth of the original bag should be flat, the left hand pinched tightly, and then use the right hand to fold the remaining right side to the left, so that the upper mouth of the whole bag folded is parallel.

5. Finally, the wire can be folded forward and semi-compacted.

Apple bagging in the local stove every spring and summer, choose a waterproof paper bag, and stretch it out, and then put it on the apple, after the bagging to use the wire to tie the bag tightly, to avoid the paper bag falling, affecting the quality of the fruit, a week before the apple picking, to remove the paper bag, so that the apple is better colored. Tongji.

1. Bagging method

The apple flowering period is in March every year, one month after the end of the flowering period, you can carry out the bagging, the paper bag is opened with the palm of your hand, and then put on the apple, and after bagging, the bag mouth should be folded from the outside to the inside, and the wire of the bag mouth should be used to tie it tightly and fix it on the fruit stalk.

2. Bag removal method

Apples are bagged when they are grown, and the bags are removed a week before the fruit is harvested to facilitate apple coloring. And when removing the bag, the outer paper bag should be removed first, and the inner paper bag should be removed after waiting for three to five days, so as not to prevent the fruit from being unable to adapt to the environment and affecting the quality.

3. Precautions

When bagging apples, it is not advisable to make the fruit touch the paper bag, nor can the paper bag be attached to the fruit, so as not to affect the development and growth of the apple.

<> bagging is an important measure to improve the quality of apples, but there are still problems in the production of non-standard bagging technology and uneven quality of bagging fruits. Let's introduce the key points of the new technology of apple bagging and talk about the methods and steps of apple bagging for reference.

Practical experience has shown that not all apple orchards are suitable for bagging. Under normal circumstances, the bagging should choose a plum blight-free tree with reasonable distribution of backbone branches, ventilation and light transmission, and strong tree strength.

In orchards with closed canopy and high density, the mutual shading of paper bags was serious, which aggravated the occurrence of leaf spot and affected the formation of flower buds. Trees with moderate and weak growth tend to have better fruit coloring under natural conditions, but they are poorly colored after bagging.

The best bagging time varies from region to region and for different apple varieties. It has been proven that 45 days after the flowering is the best time to implement bagging is the best time.

In Pingliang area, Gansu Province, generally in early June began to bag, the end of the month, the specific bagging time should be 8 11 o'clock and 15 17 o'clock, rainy weather, noon (11 15 o'clock), dew can not be implemented.

At present, there are many types of fruit bags on the market, and the quality is uneven due to the lack of national unified standards and effective management systems for fruit bag production.

According to the side width test should choose reliable quality double-layer wood pulp paper bags, paper bags are required to be all wood pulp paper, high mechanical strength, wind, sun, rain after no brittleness, no deformation, shading, breathability, waterproof, antibacterial, insect resistance, in line with national or local standards requirements.

When bagging the bag, open the bag body, hold up the bottom of the bag, and open the vents of the two feet at the bottom of the bag to reduce the humidity and temperature in the bag and prevent sunburn and rust.

Young fruits should be suspended in paper bags**, otherwise it is easy to cause the bag body to rub against the fruit surface, Tsubaki elephant thorn fruit, liquid medicine and fungal and insect secretions to pollute the fruit surface.

Do not touch the fruit surface with your hands when bagging, and do not pull the fruit to prevent straining the base of the fruit stalk, causing fruit drop or slow fruit growth. After the bagging is over, the bundle should be appropriate, too tight will hurt the fruit stalk, too loose will cause pests to enter.

The correct way to bagging apples is as follows:

1. Choose the right bagging. You can choose a professional apple bag that is breathable, permeable and suitable for the caliber, or you can use a homemade transparent plastic bag. Gently remove the apples until they are fully ripe and do not damage them.

Place the apples in a clean, dry apple bag and secure the opening of the bag to the bottom of the apples, making sure the bag completely covers the apples and trying to avoid excess air inside the bag.

2. For re-bagged apples, remove the old bags and the dust and debris attached to the surface of the apples first, and then bagging them to ensure the best results. Finally, place the apples in a ventilated, dry, protected from direct sunlight and high temperatures, and can be placed in a cool room or in a well-ventilated pantry.

3. The process of bagging requires care and patience, and the special letter is for large-scale orchards, which requires a lot of manpower and time investment. However, in the long run, apple bagging can save on growing costs and improve yield and quality. By bagging, the surface of the apple can create a relatively closed environment.

4. In this environment, the water inside the fruit is not easy to evaporate, and the flesh is not easily affected by external gases, dust, insect pests and other factors, so that apples can survive and ripen under extreme climatic conditions.

5. In addition, the correct bagging can also make the characteristics of apples more prominent. For example, if you choose a clear plastic bag for bagging, the apples will receive sunlight well when they are ripe, resulting in a more ruddy, full-bodied color and a better taste. At the same time, because the apples are wrapped in bags, the possibility of mechanical damage to the fruit is reduced, so the apples can effectively reduce wear and tear during transportation and storage.

6. In short, apple bagging is a relatively simple and convenient way to preserve apples and prevent insects. In the long run, bagging can improve yield and quality, save on production costs, and provide a better food experience for disliked consumers. While the bagging process can be time-consuming and labor-intensive, it is worth the investment in the long term for both growers and consumers.

<> first put your hand into the bag to open the bag, so that the bottom air hole opens, and then put the young fruit from the mouth of the bag into the bag, and then fold the bag mouth from both sides to the fruit stalk, and the mouth of the bag can be tied tightly with nylon thread. Different varieties of apples have different bagging times, among which the early red varieties are bagged from the end of May to the beginning of June. After bagging, the phenomenon of bagging loosening should be dealt with in time, reduce the amount of nitrogen fertilizer, control the growth of fruit trees, and remove the inner bag to avoid the high temperature period.

First, the fastest way to bag apple bags

Apple bagging generally follows the principle of first setting the apples on the tree, then setting the apples under the tree, first putting the apples inside, and then putting the apples on the outside, first put your hand into the bag to open the bag, so that the bottom pores are opened, and then put the young fruits into the bag from the mouth of the bag, and then fold the bag mouth from both sides to the fruit stalk, so that the young fruits are suspended in the bag, do not stick to the bag wall, prevent sunburn, and finally tie it tightly with nylon thread at the mouth of the bag.

Second, the time of apple bagging

1. Yellow-green variety.

Generally, it is chosen to carry out bagging and renting 10-15 days after the flowers fall.

2. Early maturing red varieties.

Generally, bagging is carried out from the end of May to the beginning of June, and 30 days after the flowers fall is the best time. For varieties with severe physiological fruit drop, bagging should be carried out after the end of fruit drop.

3. Late-maturing red varieties.

Bagging is generally carried out after the flowers, and the best time for bagging is from June 5 to June 20.

3. Precautions for bagging

1. Conduct regular inspections after bagging, and find that the bagging is loosened, hanging bags, leakage bags and other phenomena should be dealt with in time.

2. The high temperature and high humidity environment in summer is easy to make the autumn shoots grow vigorously and compete with the fruiting branches for nutrients. Therefore, after the fruit trees are bagged, it is necessary to control the application of nitrogen fertilizer and control the growth of fruit trees.

3. When unpacking the bag, you must first remove the outer bag, after an interval of 3-5 days, and then lift the inner bag, avoid the high temperature time at noon to lift the inner bag, otherwise in case of strong sunshine weather, the fruit surface will be seriously sunburned, the fruit surface will be ugly, and the commodity rate will be reduced.

The fastest way to bag apples is to stretch the paper bag open, open the air permeable hole on the paper bag grinding height, and stick the apple handle in the gap between the bag mouth, and align and pinch it tightly on both sides to ensure that the apple is in the middle of the bag, the specific steps are as follows:

Tools Raw materials: special paper bags, apples.

1. Open the mouth of the paper bag, put your hand into the paper bag to open the air hole, and hold the bottom of the bag with the other hand to make the paper bag into a lantern shape.

2. Hold the middle two sides of the paper bag with both hands, and wait for the apples to enter the bag safely and lift it up, so that the fruit stalk is sandwiched at the bottom of the middle crack.

3. Press one side of the wire on the other side, fold and press the crack tightly, and pinch it with the right hand when it is combined with the front blind ulnar surface.

4. The left hand will have one side of the wire, press the wire backwards, the upper mouth of the original bag should be flat, the left hand should be pinched, and then the remaining right side will be folded with the right hand to the left, so that the upper mouth of the whole bag folded is parallel.

5. Finally, fold the wire loose ruler forward in half and compact.

1. Sterilization in advance: Be sure to spray a fungicide for the fruit before wrapping the bag for apples. 2. Strict vegetables and fruits:

Remove stunted and injured apples before bagging. 3. Calcium supplementation before the set: spray calcium-rich liquid fertilizer for apples at least 2-3 times.

4. Reasonable bagging: put the film bag on the apple, and then seal the bag tightly.

1. Sterilization in advance

Before the apple film bag, it is necessary to carry out thorough sterilization and insecticide, the flowering period of the plant to the bagging belongs to the sensitive period of fruit infection, ring disease, anthracnose, etc. will invade the fruit and hide during this period, so the fungicide must be sprayed before bagging.

2. Strict vegetables and fruits:

When setting the fruit for the apple, keep a central fruit and the fruit with a long fruit stalk every 20-25 cm, and remove the stunted and injured fruits in time, and strictly control the amount of fruit retained, which is conducive to the concentration of nutrients after the film bag.

3. Calcium supplementation before set

Because the apples after the film bag have been in a dark and humid microenvironment for a long time, the absorption capacity of calcium is particularly poor, so it is necessary to spray calcium-rich liquid fertilizer before bagging, at least 2-3 times.

4. Reasonable bagging

When wrapping the bag for apples, first put the bag on the fruit, and then seal the bag tightly, pay attention not to stick to the young fruit, so as not to cause rough peel and cause fruit rust, and the leeward side of the crown and the lower part of the crown should be dominated by paper bags.
