What are the causes of rotten fruit in red jujube and what are the control measures?

Red jujube has the effect of nourishing qi and replenishing blood, so it is deeply supported by girlfriends in the market, and quite a lot of people grow it. Now it is exactly the red jujube ripening season, but some farmers report that red jujube has rotten fruit, causing relatively large losses. So what are the causes of red jujube rotten fruit? Follow the editor and take a look.

I. Causes of red jujube rotten fruit

1. Fruit cracking

When red jujube cracks, cracks appear on the fruit surface, and pathogens take the opportunity to invade, causing the fruit to be infected by pathogens and rot.

2. Damage

During fruit harvest, improper harvesting by fruit farmers, unsuitable harvest time, or mechanical damage during transport will all lead to rotten fruit during the storage and transport of red jujube.

3. Alcoholic softening

During storage, jujube fruit undergoes alcoholic fermentation and becomes soft, eventually becoming moldy and rotten, mainly caused by an improper storage environment.

II. Control measures

1. During planting management, comprehensive measures should be adopted to reduce the occurrence of fruit cracking and lower the degree of rotten fruit. 20-25 days before red jujube ripens, use 1 tube of jujube anti-cracking and anti-rot agent, mix with 25 kg of water, and spray the whole tree until water drips from the leaves. Repeat once after a week, which can effectively reduce fruit cracking and effectively prevent rotten fruit.

2. Harvesting must be scientific and reasonable, grasp the correct harvest time, and storage and transport must also be reasonable to reduce the occurrence of rotten fruit as much as possible. During harvest, use manual picking as much as possible, use the beating harvest method less, and promote the chemical harvest method. The picking basket must be well padded, and the fruit after picking must be prevented from bumping and pressure damage to reduce mechanical damage. Fruit found to be damaged should be removed promptly.

3. The humidity of the storage environment must be suitable, so as to avoid excessive humidity causing rotten fruit and to prevent alcoholic softening. When the humidity of the storage environment is relatively high, rotten fruit is extremely serious. Before storage, the environment needs to be cleaned thoroughly, and if conditions permit, it can be disinfected once. During storage, it needs to be kept relatively dry.
