Key points of maturity Management of Dongzao Jujube

Now it is the period of maturity and listing of winter jujube, although the demand for nutrients and water of winter jujube is not as large as in the previous period, but it is also the most critical period, and the management of ripening period directly affects the quality and yield of fruit. So what should be done during the mature period of winter jujube? Let's take a look.

1. Improve the finish of fruit surface.

The fruit surface finish of Dongzao jujube is affected by temperature, light and water. In addition, excessive spraying concentration will also affect the fruit surface finish. Chelating titanium fertilizer can be used to improve fruit stress resistance, reduce the effect of chemicals, and improve fruit surface finish. In addition, it is necessary to loosen the soil in time, weed and support branches. The main producing area of winter jujube in China is the north. After the rainfall in late summer and early autumn, the soil consolidation is more serious, so it is necessary to loosen the soil in time, weed, improve soil permeability, increase root absorption capacity, and improve fruit quality and yield. When the fruit tree has a large number of fruit, it can prevent the jujube tree from overloading and breaking the branches through supporting branches.

2. Strengthen fertilizer and water

In the stage of winter jujube changing color to maturity, its demand for fertilizer and water is not as much as that in the fruit expansion period, but it should also ensure sufficient water and replenish the nutrients needed for normal growth in time. At this time, there are mainly two kinds of fertilization: base fertilizer and foliar fertilizer, the base fertilizer is mainly high potassium fertilizer, which makes the fruit expand and change color, while the foliar fertilizer can spray chelated titanium fertilizer and potassium dihydrogen phosphate, which can increase the sweetness of the fruit.

3. prevention and control of diseases and insect pests

In the mature period, the prevention and control of diseases and insect pests should not be taken lightly. At this time, the common diseases and insect pests are red spiders, heart-eating insects, blind bugs, fruit shrinkage, anthrax, brown spot and so on. The commonly used control agents are red spiders, heart-eating insects, bug bugs, fruit shrinking disease, anthrax, brown spot and so on.

4. Guard against natural disasters

In the mature period of winter jujube, it is necessary to guard against natural disasters, when the temperature drops suddenly and is prone to bad weather, so we should pay attention to the changes of the weather in time and take preventive measures in time when we encounter natural disasters such as strong wind, rainstorm, hail and so on. minimize the damage caused by natural disasters to jujube trees.

The above is the main points of winter jujube mature management, hope to help you, want to know more related knowledge, please pay attention to us.
