How to prevent jujube fruit drop? These practical tips you need to know

Recently, many areas have had excessive rain, and many jujube trees drop a large amount of leaves and fruit during the young fruit stage, causing serious yield reduction. The jujube trees of a certain Fan in Sanfen Village, Nanhuangqin Village, Duancun Township, Xian County, Cangzhou City, are still green with lush branches and leaves, and the developing jujube fruits bend the branches. Even the seedless jujube, which normally has serious pre-harvest fruit drop, has not turned red or dropped this year and is growing well. Fan's specific methods are:

Take measures suited to local conditions according to this year's climate characteristics. Since June this year, there has been a lot of rain and high field humidity, which is suitable for small jujube fruit set. One jujube bearing shoot can grow dozens, even hundreds, of small jujubes. However, because there are many flowers and many jujubes, the tree's nutrient consumption is large. In addition, with more rain, the tree's transpiration is high, causing severe nutrient deficiency in the tree, and the leaves have been yellow ever since the trunk girdling. In response to this situation, he fertilized the jujube trees in time and combined it with foliar spraying to promptly supplement nutrients to the jujube trees, restore tree vigor, and avoid young fruit drop.

During the growth and development of jujube fruit, there is often more rain, and diseases occur early and severely. For this reason, this year Fan carried out disease control in advance, starting to use fungicides in June, and sprayed a protective agent again every half a month to prevent disease invasion, achieving good results. The agents he chose were imported thiophanate-methyl and Shanghai-produced fruit rot fungicide.
