Apple tree wintering management mo relax

The management of apple harvesting consequences must not be relaxed. If left unchecked, the tree will be weak and the fruit trees will not survive the winter, which will inevitably affect the yield and quality of the fruit trees in the coming year.

        Re-application of base fertilizer

        The application of autumn-based base fertilizer can increase the fruit setting rate of apple trees by more than 10%, and the yield and quality are also significantly improved. Mainly organic fertilizer, with a certain amount of available nitrogen, phosphorus, potassium and trace element fertilizers, can be combined with soil and support; late-effect fertilizer and quick-acting fertilizer combined.

        Plastic trim

        Different apple varieties have different germination and branching power. For varieties with strong sprouting power and strong branching ability, the crown of the tree is easy to be closed, the amount of pruning is large, and the cutting is necessary to reduce the cuts to improve the lighting conditions. On the contrary, the germination force or the branching ability is not strong, the amount of pruning should be controlled, otherwise there will be a phenomenon of shrinking the crown and bare branches.

        Qingyuan

        The dead leaves, dead fruits, and fruit falling in the orchard are burned intensively. Combine winter shears to remove diseased branches and insect branches, scrape off coarse and old bark to reduce or eliminate wintering pests and diseases.

        Pest control

        1. Scratch the skin: scrape off the diseased skin of rot disease, dry rot and other diseases of the branches, and then apply "protection tree generals" to kill the bacteria and die.

        2. Whitening the branches: Whitening the branches of the fruit trees with the "General Tree Protection" + stone sulfur mixture to prevent pests and diseases and daily burning, and protect the tree body.

3. Spray disinfection: In the dormant period, the whole garden will be sprayed with “protecting tree generals” to keep warm and antifreeze, eliminate wintering pests and diseases, protect flower buds, and make fruit trees survive in winter.

        The management of apple trees in winter directly affects the production in the coming year. Do a good job in the wintering management of the orchard, improve the nutrition of the tree, supplement the energy, do the trimming, heat preservation and antifreeze, and make the fruit trees survive the winter.
