The reason why the latest jujube trees blossom and fail to bear fruit

Sometimes some growers will find that the jujube trees grow well and have luxuriant branches, but when they bloom, they will not bear fruit, or bear very little fruit. What is the reason for this phenomenon? In fact, there are many reasons why jujube trees bloom and fail to bear fruit. Next we will introduce various reasons, as well as specific prevention and control methods.

First, reasons

The most common reason is that the tree is too prosperous, which is likely to be overnutrition, too exuberant growth, too exuberant branches and leaves, which will lead to jujube consumption of too much nutrition, difficult to enter reproductive growth, or no nutritional support after entering reproductive growth. The second reason may be the hot and dry weather, which may affect the survival of pollen and the success rate of pollination if we encounter high temperature and drought during flowering and fruiting. Third, it may be due to inadequate preparation of pollination trees, it will lead to poor pollination, unable to bear fruit. In the end, it may be because it rains and blossoms and meets a rainy day, the pollen absorbs water and splits, and death cannot be fertilized.

II. Prevention and control methods

1. Controlled growth

In the early stage, we should pay attention to trunk shaping, and after determining a good tree shape, we can prune the branches that disturb the tree shape at any time, excess consumption of nutritious branches, and appropriate coring of some branches. This can control vegetative growth. Then fertilize in the early stage, control the individual use of nitrogen fertilizer, it is best to apply farm manure, and do not apply too much nitrogen fertilizer.

two。 High temperature and drought

Jujube flowering from May to July, in many places is the hot season, this time is high temperature, but there may be drought, there may be rain. If there is a drought, you can water it after cooling in the evening. Sticking to it every day will relieve some of the drought, or spray water to increase the humidity of the air. Pay attention to the weather, collect pollen before rain, and pollinate artificially after rain.

3. Pollination tree

Jujube trees are monoecious and self-pollinated, but some varieties also need pollination trees in order to increase fruit rate and ensure fruit. Sometimes some growth regulators can be used to regulate growth. Protect the flowers and promote the fruit. For example, gibberellin, sprayed after flowering, can bear fruit without pollination.

Jujube flowering does not bear fruit, it is affected by its own factors, but also by some other environmental factors. However, no matter what kind of factors, we should do a good job in these management, and improve the growth conditions and growth potential of jujube trees.
