Dressing and shaping

Pruning apricot trees in winter is pruning in dormancy. The key point is to cut off the weak branches, dead branches and clustered branches. Thereby promoting the early formation of fruit buds. At the same time, rationally transform the tree shape, pay attention to the opening angle and maintain good lighting and ventilation conditions. Pay attention to protect the wound in time after pruning, and apply corresponding drugs to accelerate the wound healing and prevent the wound from cracking.

Removing fallen leaves, cutting off diseased branches, dead branches, pests and diseases, centralized burning and removing weeds around can prevent the source of disease and kill overwintering eggs. Remember to apply oil "healing film" to the wound in time to promote wound healing.

Heat preservation and antifreeze

Spraying apricot trunk and branches with "General Tree Protection" 100 times liquid can play the roles of sterilization, heat preservation and anti-freezing. It needs to be sprayed twice, once before the soil freezes and once in early spring.

Eliminate pests and diseases

Scraping gum disease

Gummosis is a common disease of apricot trees, which affects the yield and quality of fruits and even leads to the death of the whole apricot tree in severe cases. To prevent gummosis, clean the gums first, and then apply "General Shu" emulsion on the wound to make the diseased skin fall off quickly and prevent the invasion of germs. In order to eradicate gummosis, the cationic activator "Zhuhuawang No.2" can be applied to apricot trees in winter to control the growth and achieve the control effect.

Control the heart eater

Usually, the method of inserting poison string is used to control stem borers, and the effect is good. The specific operation is to sharpen one end of the stick, dip it in insecticide, and then insert it into the insect mouth, which can not only block the defecation passage of the stem borer, but also poison the pests deep in the tree.
