Why is bordeaux cracked now? How to deal with the cracked jujube?

The main reason of jujube cracking near maturity is that it was knocked down by heavy rain after high temperature drying, which led to the fruit absorbing a lot of water in a short time and cracking the epidermis. This is a physiological phenomenon. In order to prevent this from happening, we can: 1 in the near future, and do a good job of ditching and drainage around the tree; 2. Cover jujube roots with film. The purpose of this is to reduce the infiltration of rainwater, so that the roots do not absorb a lot of water in a short time. In addition, attention should be paid to strengthening the ventilation and light transmission of plants when pruning in the future, and some calcium-supplementing fertilizers such as calcium superphosphate should be applied to jujube orchards lacking calcium, which can also reduce the occurrence of fruit cracking.
