The latest apple bag picking time and key points of management after bag removal

Apple bagging technology is very mature in our country, and it is used in many areas, but some fruit growers are not very proficient in apple bagging technology, such as apple bag picking time and post-harvest management, and so on. So today, let's learn about apple bag picking time and bag picking management.

The best time to pick the bag of apple

Different regional climate, different nature of soil, different apple varieties and other factors will affect the apple bag picking time to a certain extent. If the yellowish green variety uses a single-layer bag, the bag can be removed during harvest; if it is a red variety and single-layer bag, the bag can be removed one month before harvest. First, the bag body is torn open in the shape of an umbrella, covering the fruit to prevent direct sunlight on the fruit surface. Take off all the bags after 7 days and 10 days, which can prevent sunburn and accelerate fruit coloring. If it is a red variety and uses a double-layer bag, generally remove the bag 30-35 days before harvest, first remove the outer bag, and then remove the inner bag after 4-5 sunny days. The best time to pick bags in a day is from 9 a.m. to 11:00, and from 3 p.m. to 5 p.m., when picking bags, you must avoid the strongest sunlight at noon to avoid sunburn.

Management after bag removal

1. Autumn scissors

The growth of apple trees needs a good light environment, so pruning throughout the year is very important. As far as autumn pruning is concerned, it can not only increase the light, but also improve the quality of apple trees. Autumn shears should make reasonable use of the light gap between branches and branches, so that the light can be evenly illuminated on each branch.

2. Pick leaves properly

The purpose of this practice is to increase the light area of the fruit, and it is generally better to pick leaves in September, whether it is the fruit on the crown or the fruit in the lower part of the crown.

3. Turning fruit and padding fruit

The purpose of this practice is to color the fruit evenly, generally turning the fruit once within a week after picking the bag, but do not twist the fruit too hard, causing the fruit to fall off.

4. Laying reflective film

The main purpose of laying reflective film is to make the fruit in the sunken part and the lower part of the crown and the north of the crown also be exposed to light, so as to increase the rate of full red fruit.

5. Spraying plant growth regulators

Many fruit growers will spray plant growth regulators, the benefit of which is to prevent pre-harvest fruit drop, promote color change, and increase fruit coloring.

For bagged apples, picking the bag is also very critical, if you remove the bag too early or too late will lead to poor quality of the apple.
