Pear bagging time, pear bagging time and method

Pears should be bagged after the end of fruit thinning in early to mid-May, and the bagging time should be 9:00 a.m. to 11:00 a.m. and 2:00 p.m. to 6:00 p.m. on sunny days.

The biggest benefit of fruit bagging is to improve the appearance quality and reduce pesticide residues, and the improved appearance quality is highlighted in the surface smoothness and comprehensive coloring.

The earlier the bagging time, the better the appearance and quality of the bagging fruit. However, if the bagging is too early (before physiological fruit drop), fruit will fall in the bag, which will increase production costs and reduce the quality of the pulp. Therefore, it depends on the fruit variety and cultivation.

Insecticides and fungicides should be sprayed once before bagging to eliminate pests and diseases and protect the fruit. Insecticides can be selected trichlorfon, pyrethroids, etc., and fungicides can be selected methyl tobuzin.

1.What is pear bagging?

Pear bagging is a fruit tree management technique that is suitable for fruit trees such as peach, persimmon, and grapefruit. Bagging protects the fruit from pests and sun and rain, facilitates the growth and development of the fruit, and also improves the quality of the peel.

2.Bagging time.

The time for pear bagging is generally 20 to 30 days after the flowering of the fruit tree, after the fruit has become large. In order to protect the fruit, the earlier the bagging time, the better, but if the bagging is too early, it will affect the self-repair ability and self-defense ability of the fruit, which is not conducive to the healthy development of the fruit.

3.Bagging steps.

The steps for pear bagging are as follows:

1.Choose a transparent polyethylene bag or paper bag, the length of the bag should exceed the length of the fruit, and the bottom of the bag should be left open to facilitate the drainage of the fruit.

2.Put the bag over the fruit and fix the mouth of the bag on the fruit branch to avoid the fruit moving or the bag from falling.

3.Pay attention to leave a gap between the fruit and the bag, so as not to cling to the fruit and affect the normal growth of the fruit.

4.Bagging precautions.

There are the following things to pay attention to when bagging pears::

1.Choose ripe fruit bagging to prevent bagging before the fruit is ripe, otherwise the fruit will not grow normally and affect the quality.

2.Clean the surface of the fruit before bagging to prevent substances such as soil and bacteria from entering the bag and affecting the quality of the fruit.

3.After bagging, it needs to be checked regularly to avoid the adhesion between the fruit and the bag, which will affect the normal growth of the fruit.

5.Bagging effect.

Pear bagging can prevent the fruit from being eroded by sun, rain and insect pests, and promote the normal growth and development of the fruit. At the same time, bagging can also improve the quality of the peel, so that the fruit can better stay fresh and last longer.

6.Precautions for bagging.

The following precautions should be paid attention to during the pear bagging process:

1.When bagging, be sure to tighten the bag to avoid gaps between the bag and the fruit, which will affect the effect.

2.Pear bagging is generally done 20 to 30 days after the fruit tree has flowered.

3.When bagging, it is necessary to select healthy and ripe fruits for bagging to prevent affecting the quality of fruits.

7.Conclusion.

Pear bagging can prevent the fruit from being eroded by sun, rain and insect pests, improve the quality of the peel, and increase the commodity value of the fruit. In order to ensure the effect, it is necessary to pay attention to the timing of bagging, the selection of bags, the selection of fruits and regular inspections.

The time of pear tree bagging is generally 15-40 days after flowering, when the young fruits grow to the size of soybean grains or from the end of May to mid to early June.

For pear tree bagging, it is also necessary to pay attention to the flexibility of the bagging time according to the variety and the early and late maturity period. For example, it is recommended that the bagging be completed in mid to late May for early-maturing varieties, and the bagging should be completed in mid to early June for late-maturing varieties, and for example, the bagging of early-maturing crown varieties should be completed by the end of May.

The late-ripening pears generally start to be bagged in early June, and the pears generally need to be bagged twice, the first time in mid to late May, the first time in mid to late May, and the second in mid to late June. In addition, the bagging time of pear trees should be sooner rather than later, if the bagging is too late, it is easy to aggravate the problem of increasing rust on the fruit surface.

Pear tree bagging technology:

1. Before bagging, it is necessary to reasonably thin flowers and fruits

When the pear tree thins the flowers and fruits, it is necessary to improve the yield and quality of the fruit tree, and it should be determined according to the pear tree variety, tree potential, fruiting amount, etc., and the fruit should be thinned early if there are many flowers, many fruits, and the weak tree should be thinned early, and vice versa. Before bagging, it is necessary to determine the reasonable load, and the amount of fruit should be increased by 15-20 compared with the actual load, so that there is room for choice when bagging.

2. Pest control before bagging

Before bagging pear trees, it is the initial infestation and disease stage of pests and diseases. Generally, spraying is required before bagging to prevent the occurrence of common pests and diseases such as scab and ring disease. Generally, choose to spray 1-2 times of insecticidal and bactericidal mixtures with low toxicity, less residue and good efficacy, focusing on spraying the fruit surface to kill the fungus and insects on the fruit surface.

<> pear, the bagging time is within 20 mm of the fruit transverse diameter, which is generally carried out 15-45 days after falling or swimming in the flowers, after fruit thinning and before the grinding section of the rust spots at the fruit point. Pear bagging can be carried out at 9-11 a.m. or 3-6 p.m., fruit bags with good shading, wind and rain after not breaking, no waxing is better, but also pay attention to dew and medicine can not be bagged when dry.
