What is the role of fruit bagging (the benefits of fruit on the tree needing net bags)

Fruit bagging is a very common operation method with many advantages. It can ultimately improve the quality of fruits, increase yields, and increase farmers' income . Specifically, the main functions of fruit bagging are as follows.

Advantages and functions of fruit bagging

1. Reduce pesticide residues . After bagging, the fruits are isolated from the outside world, and the fruits will not be contaminated when spraying pesticides and fertilizers.

2. Improve the quality of the fruit . After the fruit is bagged, the growth of the fruit is not affected by the external environment, so the quality is better.

3. Reduce the risk of pests . Bagging fruits can prevent the invasion of most pests.

4. Reduce the impact of natural disasters . After bagging, rainy weather, strong sunlight and other natural weather conditions will not affect the fruit.

Taking grape bagging as an example, its advantages include :

① Improve the smoothness of the fruit surface

②Reduce fruit diseases and pests

③ Improve fruit coloring

④Reduce the number of times pesticides are used

⑤Reduce pesticide residues in fruits

⑥Reduce bird damage

How to bag fruit

1. Bagging should be done on a sunny day .

2. Before bagging, remove the excess leaves on the fruit stalk or base of the bunch.

3. Before bagging, spray the fruit all over with insecticides and fungicides allowed for use in pollution-free food. Wait until the liquid medicine dries before bagging. The fruit that was sprayed should be bagged on the same day.

4. Bananas are bagged 15-20 days after buds break. Longan and litchi are bagged after fruit thinning. Pears and peaches are bagged about 30 days after flowering. Mangoes are bagged 45-60 days before harvest. Loquats are bagged about 30 days after flowering, after fruit thinning and fruit set. Grapefruit and tangerines are bagged from mid-May to early June.

Fertilizer and water management after fruit bagging

In bagged orchards, fertilizer and water management and leaf protection should be strengthened to maintain long-lasting and healthy tree growth and meet the needs of fruit growth.

Since the calcium content in the fruit of bag cultivation decreases, it is easy to suffer from bitter pit disease, etc., so spray 300-500 times of amino acid calcium or ammonia calcium or amino acid compound micro-fertilizer once a month from July to September.

Spray 500 10-6 rare earth once in late June, 40 days and 20 days before harvest, or spray photosynthetic micro-fertilizer, Nongjiawang and other micro-fertilizers in June, July and one month before harvest to increase the soluble solids content of bagged fruits.

During the fruit expansion period and before removing the bags, the fruit should be watered thoroughly to meet the water needs of the bagged fruits and prevent them from getting wet.
