New peach tree bagging technique: bag one month after flowering, and later-stage management is very important

For the bagging method for peach trees, first of all it is best to use paper bags, which require good permeability, sufficient light-blocking and water-absorbing properties, and an even coating inside of low-toxicity, low-residue fungicides that are harmless to the fruit. When bagging, first open the bottom of the paper bag, then carefully insert it from the bottom of the young peach. When inserting, do not injure the peach body and do not break the fruit stalk. Place the young peach in the center of the paper bag and do not let the young peach touch the paper bag. Note that every fruit must be properly bagged to prevent omissions.

1. Bagging time

Peach trees are generally bagged one month after the peach tree flowers. The best bagging time for peach trees is when the peach tree enters the hard pit stage at the second physiological fruit drop. Before bagging, the orchard needs to be thoroughly disinfected, and bagging can be done once the liquid has completely air-dried. We can use agents such as thiophanate-methyl for disinfection. Note that bagging cannot be done on foggy days; this is to prevent rain from washing away the liquid and making it ineffective.

2. Benefits of bagging

Bagging helps the fruit expand and increases fruit yield. Reasonable bagging helps enhance quality, making the flesh more tender and tasty and the fruit surface smooth and glossy. It helps reduce the occurrence of fruit cracking in some varieties prone to cracking. Bagging also helps reduce the incidence of various pests and diseases, such as peach fruit borer, scab, and so on.

3. Bagging method

1. Bag selection

The choice of bag is very important, and there are certain requirements for its material. Plastic has very poor permeability and cannot drain water, thereby increasing the rate of rotten fruit and the incidence of disease. It is best to use paper bags for bagging. Paper bags require good permeability, an even coating inside of low-toxicity fungicides that are harmless to the fruit, sufficient light-blocking and water-absorbing properties, and low residue.

2. How to bag

When bagging, first open the bottom of the paper bag, then carefully insert it from the bottom of the young peach. When inserting, be careful not to injure the young peach, otherwise the young peach will have a wound and cannot continue to grow. Also note that the fruit stalk cannot be broken. Carefully place the young peach in the center of the paper bag to prevent the young peach from touching the paper bag. Every fruit must be properly bagged to prevent omissions.

3. Remove bags at the right time

Removing bags at the right time can effectively improve fruit quality. Generally, bags are removed twice. When the fruit develops normally, remove the outer bag of the paper bag at about three weeks before, and then remove the inner bag after about one week. Note that bags should not be removed on sunny days, to prevent the fruit from being unable to adapt to sunlight and developing sunscald. After removing the bags, remove the shading leaves around the fruit, which helps the fruit tree color and ensures even fruit color.
