Kiwifruit frostbite after clever handling
Strengthen orchard management After kiwifruit trees have been frozen, they should promote recovery of tree vigor and strengthen soil fertilizer and water management. Spraying quick-acting nutrient solution, applying organic and inorganic quick-acting fertilizers, timely filling water, restoring tree vigor, and prompting early spring new shoots.
After pest control of the kiwifruit tree is carried out, the tree's ability to resist pests and diseases will be reduced, and secondary diseases will occur easily. The frozen branches should be cut off promptly, and the cuts should be closed with 50 times oil emulsion, and 5 bumei before germination. The lime sulfur agent prevents, particularly strengthens, the prevention and treatment of kiwifruit bacterial ulcer disease.
Seedlings and saplings that are severely affected by freezing should be quickly replanted, regrafted or replenished as soon as possible. After the emergence of new shoots, 2 to 3 shoots will be left, and the rest will be cut off. Multiple main branches will be placed in the freezer. Gradually grafted varieties, strengthen the management of the year. The partially frozen trees on the ground, before the injury, removed the above-ground parts from the base of the trunk, sprouted vigorously and sprouted, and the summer highs (about 1 meter) were grafted to achieve the germination of the year, grafting of the year, and the shelves of the year.
The first result tree, which bridges the lightest freezing injury, is used to bridge the frost damage site of the main trunk and restore the tree vigor before or during the period from July to August.
