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

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

I. Causes of rotten fruit in red jujube

1. Fruit cracking

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

2. Occurrence of damage

During fruit harvesting, improper harvesting by fruit farmers, unsuitable harvesting time, or mechanical damage during transportation can all lead to rotten fruit during the storage and transportation 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, dilute with 25 kg of water, and spray the whole tree until the leaves drip, then repeat once after a week. This can effectively reduce fruit cracking and effectively prevent rotten fruit.

2. Harvesting must be scientific and reasonable, with the correct harvesting time grasped, and storage and transportation must also be reasonable to reduce the occurrence of rotten fruit as much as possible. During harvesting, manual picking should be used as much as possible, less use should be made of the beating harvesting method, and the chemical harvesting method should be promoted. The picking basket must be well padded, and the fruit after picking must be prevented from bumping and compression damage to reduce mechanical damage. Any fruit found to be damaged should be removed in time.

3. The humidity of the storage environment must be appropriate, so as to avoid excessive humidity causing rotten fruit and to prevent the occurrence of alcoholic softening. When the humidity of the storage environment is relatively high, the rotten fruit phenomenon 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.
