Bagging pomegranates can improve quality, increase yield, prevent pests and diseases, raise the rate of premium fruit, reduce mechanical damage during harvesting and transport, and keep the fruit surface clean.
Choosing bags for pomegranate bagging:Generally, bagging bags are divided into paper fruit bags and plastic film fruit bags.
Paper bags have good air permeability, and bagging can be done right after fruit set. After bagging, there is no need to spray insecticides on the tree again. The fruit ripens early, has good color, and has excellent quality. Its disadvantages are that it can be damaged, the cost is high, and the cost is high. After the fruit ripens, it must be harvested in time. If delayed, the fruit surface is prone to aging, affecting the appearance quality and marketability.
Plastic film bags have the advantages of low price, easy operation, can delay harvest for a relatively long time (about 30 days), do not cause the fruit surface to age, and greatly increase yield. Their disadvantages are that due to poor air permeability, early use will affect fruit development, so they can only be used starting in mid-to-late July. Since there is no protection in the early stage, pest and disease control should be carried out according to bare-fruit management in the early stage; due to poor air permeability, fruit coloring is poor, affecting the appearance color, and market competitiveness is not strong.
In addition, because harvesting is too late, the tree's post-harvest recovery period is noticeably shortened, and before overwintering the tree lacks nutrients, reducing the tree's cold resistance for overwintering and worsening winter freeze damage to the tree.
Pomegranate bagging time and operation methods:
When using paper bags, bagging should be done after mid-June (after the fruit completes the color-change period). When using paper bags, earlier is better than later. Generally, after bagging, thanks to the protection of the paper bag, pomegranates can be spared from insect damage. There are many varieties of paper bags used on pomegranates, but in practice, we think white wax paper bags are best, while the effect of double-layer bags and colored bags is poorer.
The method of using wax paper bags for bagging is:
1. Open the paper bag, insert a clenched left fist into the bag, extend the thumb and little finger (pointing toward the two bottom corners of the bag), then gently press the fruit bag with the right hand to make the bag puff out round.
2. Put the fruit bag over the fruit, making sure the fruit is suspended inside the bag and does not touch the fruit (be careful to prevent the fruit bag from touching the fruit, which can cause sunscald). If the fruit is set on a leafy spur, the fruiting branch should also be put into the bag together when bagging.
Because plastic film bags are not breathable and the temperature inside the bag is high, using them too early can easily cause sunscald and also affect fruit growth. Experiments have shown that plastic film bags are best used in early-to-mid August. To avoid pest and disease damage, pesticide control should also be used before bagging (the same method and chemicals as for paper bagging). There are many varieties of plastic film bags, but those with good toughness and good light transmission are best. Do not buy poor-quality fruit bags just to save money; this kind of bag does not withstand wind and rain, has a high damage rate, and affects the result.
Management methods after pomegranate bagging:
1. Promptly clear away dead branches and stem thorns around the fruit bags. Pomegranate branches are dense and bear stem thorns. After the fruit is bagged, because the fruit enlarges and hangs down with the branch, it is easy to damage the fruit bag and injure the fruit, so it should be checked frequently and handled promptly to ensure the integrity of the fruit bag and the fruit.
2. Pay attention to pest and disease control. Bagging can effectively control the damage of fruit borers to the fruit, but scale insects (pomegranate felt scale) will become more damaging because of the protection of the fruit bag. Therefore, in orchards planned for bagging, lime sulfur mixture should be applied well in early spring to control their occurrence.
