Winter pruning of Apricot trees in Aging period

During the aging period, the growth of the elongated branches of apricot trees became weaker, the new shoots became shorter, the backbone branches began to droop, the interior of the crown became bald, and the yield and quality decreased.

Pruning is mainly to renew backbone branches and branch groups, strengthen and restore tree potential, and prolong the years of economic fruit. It is necessary to change the head of the upper dorsal branch with a small angle and strong growth in the middle and lower part, or retract in the more erect branches to promote the germination and renewal of hidden buds. The upright branches and erect branches with proper position should be cultured into backbone branches and fruiting branches, which can be cultivated by means of drawing branches, cutting short branches, coring in summer and so on. For the fruiting branch group and the fruiting branch, in line with the principle of removing the weak and staying strong, the strong branches and buds were selected for renewal. Pruning causes the wound to smear the healing anticorrosive film in time to protect the growth of wound healing tissue and prevent bacteria from infecting the wound.

Spray the tree protection general in time after pruning, control the breeding and spread of airborne virus, protect plant tree self-defense reaction instinct, destroy harmful bacteria to the source, penetrate and eliminate the virus, and close the path of virus replication and transmission. Improve plant self-immunity. To prevent the harm of adverse climate (frost, sun exposure, hail, overcast and rain) to sub-healthy plants. Reduce the recurrence and recovery rate of the disease. Improve plant growth and fruit growth health index.
