Seeing fruitful harvests of mature winter jujube fruits, many people have relaxed their management. Not surprisingly, this period of time before the maturity of winter jujube is a critical period. Management is not good, and management in advance will be wasted. In management, we must grasp the following points:
1. Loose soil protection. Timely scratching loose soil, spray 800 times the new high-fat film, so that the jujube garden soil to maintain a suitable moisture, prevent cracking, improve the yield and quality of late winter jujube.
2. Prevent wind and rain hazards. Winter jujube enters the mature period to the pre-harvest period. If it encounters heavy winds and heavy rains, it often results in falling dates. In severe years, even when there are no yields, it is necessary to pay close attention to the weather forecast and take preventive measures as soon as possible.
3. Pre-harvest disease prevention and control. The jujube is susceptible to disease in the mature period to the pre-harvest period. Especially in the rainy years, there are cracking phenomena in the white mature stage. The use of tree maintenance general + strong fruit to spray the plant surface can effectively prevent viral infection. , sterilization, while preventing fruit drop, cracked fruit.
4 timely picking. In order to ensure the flavor and commercial value of winter jujube, we must do timely harvest and do not pick it up prematurely. At the same time as early as the removal of the disease, pick up the ground and stale fruit, remove the sick leaves, leaves, reduce the chance of mutual infection of the bacteria.
