Rowing loose soil
It is one of the effective ways to improve the yield and quality of winter jujube in the late stage, so as to timely preserve the loose soil and maintain a suitable moisture in the jujube soil. Generally, jujube gardens should timely draw loose soil, enhance the ability of roots to absorb water and maintain nutrients, and maximize the quality of winter jujube. In the plots where the soil in the jujube garden is particularly bad, it is still necessary to pour the water once in time.
Prevent wind and rain damage
During the period before the harvest of winter jujube, if there is heavy wind and heavy rain, it often causes jujube, and in severe years, it even causes the production to be rejected. Always pay attention to the weather forecast and take preventive measures as soon as possible to reduce the wind and rain hazard. For the winter jujube trees with more results, the rod-fixing work should be further done. For the backbone branches or large branch groups with more results, the tree body fixation should be strengthened by measures such as pulling branches and struts, and the jujube caused by the strong wind can be reduced.
Scientific disease prevention
The diseases that occur before the harvest of winter jujube include round rot, soft rot, black spot, and fruit shrinkage. In the years when the rain is heavy, there is a phenomenon of cracking fruit in the white ripening period, and attention should be paid to prevention. Chemical pesticides should generally not be used at this time. In the case of diseased gardens, the rot fruits on the trees are removed early, and the dead fruits are collected, and the diseased leaves and leaves on the ground are removed to reduce the mutual infection of the bacteria.
The jujube gardens with particularly serious diseases can use pollution-free pesticides based on biological agents. Prevention and control of winter jujube fruit cracking, maintaining proper soil moisture is the key. The main technical measure is to timely ensure the protection; if the soil is in poor condition, it should be watered in time. Production practices have shown that rainfall can cause different degrees of late cracking, but watering does not occur.
Picking at the right time
To ensure the quality of winter jujube to ensure the flavor and commodity value of winter jujube, we must do timely harvest, do not pick it too early. The specific picking time should be reasonably determined according to the purpose of picking: the winter jujube directly sold in the market is preferably harvested at a timely time in the semi-red period; the winter jujube prepared for storage and preservation can be picked up in advance when there is about one-third of the redness.
In order to prolong storage time and improve storage quality, it is necessary to promote picking with fruit handle; grading picking, reduce post-harvest sorting, reduce winter jujube bumping, and improve picking quality; and try to pick it up with transportation, with timely listing, or Library.

Medical sterile adhesive Hydrocolloid Dressing for wounds also make an excellent protective layer for recently healed wounds, or for partly healed wounds with granulation tissue that needs protection from surface trauma. Furthermore, a emergency hydrocolloid medical supply blood wound dressing can mold around the wound and provide insulation so that the body doesn't need to use as much energy to heal the wound.
Generally, hydrocolloid surgical Dressing last from 3 to 7 days. Sometimes a hydrocolloid dressing Wet healing starts coming up at the edges earlier. If so, it needs to be changed earlier.
