Management measures before and after harvesting of winter jujube in greenhouse

The winter jujubes in the cold sheds have gradually entered the maturity stage, and the jujube farmers cannot relax and manage the jujube garden before and after harvesting. Management measures should be done well.

Draw the loose soil and protect it at the right time

It is one of the effective ways to improve the yield and quality of winter jujube in the timely manner by arranging the loose soil in time and maintaining a suitable moisture in the jujube soil. Generally, jujube gardens should timely draw loose soil, enhance the ability of roots to absorb water and nutrients, and maximize the quality of winter jujube.

Prevent wind and rain damage

During the period before the harvest of winter jujube, if it encounters heavy wind and heavy rain, it often causes jujube to be dropped. The jujube farmers should always pay attention to the weather forecast, take precautionary measures early to reduce the wind and rain hazard, and further improve the winter jujube trees with more results. For the backbone branches or large branch groups with more results, strengthen the tree body by measures such as pulling branches and struts, and reduce the jujube caused by strong winds.

Scientific prevention and control of pre-harvest diseases of winter jujube

The diseases that occur before the harvest of winter jujube include round rot, soft rot, black spot, shrinkage disease, etc. In the white ripe period, when there is a lot of rain, there is a phenomenon of fruit cracking.

For the various diseases that will occur in the winter jujube before and after the harvest, it is necessary to pay attention to prevention at this time, and generally cannot use chemical pesticides. For diseased orchards, the rot fruits on the trees should be removed early, and the dead fruits should be picked up, and the diseased leaves and leaves on the ground should be 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. (Han Wei)
