Jujube winter management does not relax

Recently, Lu Ping, an associate researcher at the College of Forestry, Northwest A & F University, reminded jujube farmers that the management of the jujube dormancy period is very important for the high yield and income of jujube trees in the coming year. Jujube farmers should manage this period well.

In the Qingyuan Garden, the litter, fallen fruit, diseased fruit, insect fruit, and weeds in the jujube garden should be removed in time and concentratedly burned or buried with manure.

Combining the prevention and control of plant diseases and insect pests with the overwintering and clearing of the garden, artificially capturing overwintering pests such as moths and sting moths on the trees, and scraping off the rough skin and warped skin from the trunk and the main branches, and centralized destruction.

Pruning adult trees reasonably. In winter, the long branches, thin branches, endogenous cross branches, diseased and insect branches, and senescent branches are mainly removed to maintain ventilation and light transmission in the crown and adjust the tree potential to ensure three-dimensional results. The old jujube tree can be truncated or retracted from the base of the main branch to promote the germination of new branches. Pruning can also eliminate a large number of pests such as green blind maggots and red spiders overwintering eggs. After winter shearing, spray the ground part of the tree with a protective agent to prevent disease and reduce frost damage.
