A Detailed Guide to the Latest Management Points for the Winter Jujube Ripening Period
Right now it is the winter jujube ripening and marketing season. Although at this time the winter jujube's demand for nutrients and water is not as great as in the earlier stage, it is still the most critical period, because management during the ripening stage directly affects the quality and yield of the fruit. So what should be done during the winter jujube ripening period? Let's take a look together.
1. Improve fruit surface smoothness
The smoothness of the winter jujube fruit surface is affected by temperature, light and moisture. In addition, spraying pesticides at too high a concentration can also affect fruit surface smoothness. Chelated titanium fertilizer can be used to improve the fruit's stress resistance, reduce the effects of pesticides and improve fruit surface smoothness. In addition, timely cultivating and loosening the soil, weeding and propping up branches should also be carried out. The main winter jujube production areas in China are in the north. After the rainfall in late summer and early autumn, the soil becomes severely compacted, so timely cultivating and loosening the soil and weeding are needed to improve soil permeability, increase root absorption capacity and improve fruit quality and yield. When the fruit trees bear a large number of fruits, propping up the branches can prevent the jujube trees from being overloaded and breaking the branches.
2. Strengthen fertilizer and water management
During the stage from color change to ripening of winter jujube, its demand for fertilizer and water is not as great as during the fruit swelling stage, but sufficient water should still be ensured, and nutrients needed for normal growth should also be supplemented in a timely manner. At this time, fertilization mainly includes base fertilizer and foliar fertilizer. The base fertilizer is mainly high-potassium fertilizer, which promotes fruit swelling and color change, while the foliar fertilizer can be sprayed with chelated titanium fertilizer and monopotassium phosphate, which can increase the sweetness of the fruit.
3. Prevent and control pests and diseases
During the ripening period, pest and disease control should not be taken lightly either. At this time, common pests and diseases include red spider mite, fruit borer, blind plant bug, fruit shrinkage disease, anthracnose, brown spot disease and so on. Commonly used control agents include those for red spider mite, fruit borer, blind plant bug, fruit shrinkage disease, anthracnose, brown spot disease and so on. When controlling pests, pesticides should be used alternately to avoid resistance.
4. Guard against natural disasters
During the winter jujube ripening period, natural disasters should be guarded against. At this time, temperatures drop sharply and severe weather is likely to occur, so changes in the weather should be monitored in a timely manner. When encountering natural disasters such as strong winds, heavy rain and hail, preventive measures should be taken promptly to minimize the damage caused by natural disasters to the jujube trees.
The above is an introduction to the key management points for the winter jujube ripening period. We hope it can help you. If you want to learn more related knowledge, please stay tuned to us.
