At present, it is in the season of kiwi flower bud germination, and it is already clear which ones are flower buds and which are leaf buds. Therefore, one of the most important tasks of pruning kiwi trees in this season is to wipe buds. Why wipe buds The so-called wiping buds is a management technique commonly used in the shaping and trimming of fruit trees in spring and summer. It is the method of wiping and growing buds, overlapping buds, wound buds, dense buds and sprout buds by hand. Sprouting kiwifruit can serve two purposes. On the one hand, it is possible to control the number of buds, because under normal circumstances, kiwifruit has a large number of buds during spring buds. If the number of buds is not controlled, as the buds grow, the tree will appear closed after the leaves unfold, and it will also cause nutrition It consumes a lot and weakens the tree vigor; on the other hand, it can be weakened and stay strong, because the quality of the buds is inconsistent, and the growth trend after the spring buds are also inconsistent, so we must choose good quality buds to lay the foundation for high quality and high yield. How to wipe buds Grasp the bud germination time: The bud germination time of kiwifruit should be done when the quality of the buds can be clearly identified. Wipe the bud too early, the quality of the buds cannot be confirmed, and wipe the bud too late, the nutrients are ineffective and consume too much. Generally, when 80% of the buds of the crown grow to 3 to 5 cm, the buds begin to be wiped. Grasp the erasure object: The general erasure object is mainly the buds of the back, weak buds, deformed buds, no buds or few buds. For the opposite buds, whorl buds, cluster buds, adjacent buds, dense buds, etc., one bud can be selected. Wipe off the vegetative shoots on the top of the mother branch, and the extra long shoots on the main vine or the inner bore. Grasp the method of wiping buds: Kiwis of different tree ages will have different methods of wiping buds. Generally, for mature kiwifruit trees that bear fruit, the robust result mother branch can erase 10-12 buds per branch after the extra dense dense weak buds, the middle result bearing 8-10 buds, and the weak bearing mother branch 4-6 2 to 4 buds are left for buds and weak short branches, and 1 to 2 buds are left for shoots. Follow the principles of going down (back down), staying up (back up), weak and strong, and dense and thin. Grasp the requirements for wiping buds: On wiping buds, we must pay attention to three requirements. One is to pay attention to the fact that it can not be wiped off at one time in the case of the cold spring and diseases and insect pests. It needs to leave a certain amount of room, at least 20% for spare; second, the inner bore, the result of the bud germination of the main vine on the base of the mother branch Late, plus these parts should be cultivated to prepare new branches, so it is not recommended to wipe the buds, and then choose to erase when they germinate into young branches; third, due to the formation of the climate or the size of the year, the result is that the mother branch has more nutrient branches, except for erasing Except for the dense and weak branches, all the rest are kept to ensure the normal growth of the tree.
