Key points of winter pruning techniques for apricot trees in the aging stage
In the aging stage of apricot trees, the growth of each extension shoot weakens, new shoots become shorter, scaffold branches begin to droop, the interior of the canopy begins to become bare, and yield and quality decline.
Pruning mainly involves renewing scaffold branches and branch groups, strengthening and restoring tree vigor, and extending the economically productive years. Use the well-developed, vigorous shoots on the upper side of branches with a small angle in the middle and lower parts to renew the leader, or cut back to a relatively upright branch section to promote the sprouting of latent buds for renewal. For water sprouts and upright shoots in appropriate positions, cultivate them into scaffold branches and fruiting branch groups, which can be trained by methods such as bending branches, heading back, and summer pinching. For fruiting branch groups and fruiting branches, follow the principle of removing the weak and keeping the strong, and select vigorous branches and strong buds for renewal. Apply a wound healing and antiseptic film promptly to wounds caused by pruning, to protect the growth of wound healing tissue and prevent pathogens from infecting through the wounds.
After pruning is completed, spray Tree Guardian General promptly to control the breeding and spread of airborne viruses, protect the plant's innate self-defense response, destroy the nutrient sources of harmful pathogens, eliminate viruses through penetration, and block the pathways of virus replication and transmission. Improve the plant's own immunity. Prevent damage to sub-healthy plants from adverse climate disasters (frost, intense sun exposure, hail, rainy weather). Reduce the rate of disease recurrence and reactivation. Enhance the health index of plant growth and fruit growth.
