1. Key points of pruning management technology after blueberry harvesting 1. The branching point must be selected correctly for pruning blueberries after harvesting. When pruning blueberry trees, look from the bottom up from the base to find the branching point of the main branch. Cut back each main branch 40 cm from the ground. If there are no sturdy spring shoots that can be selected within a close distance above and below the cut of the main branch, simply find an outer bud point on the main branch to shorten the main trunk. If there are relatively sturdy spring shoots within a close distance of 5-8 cm above and below the cut of the main branch, then keep the spring shoots on the main branch at a length of 5-15 cm beroende på situationen och välj sedan en yttre knopppunkt för att förkorta fjäderskotten .
Note: Only the thick spring shoots closest to the bifurcation can be retained on the main branch. Only 2-3 spring shoots can be retained on each main branch. Moreover, when pruning the spring shoots, it is recommended to keep very thick spring shoots long, and pay attention to shortening the relatively weak spring shoots.
2. Pruning after blueberry harvest must leave enough green leaves. When pruning a blueberry tree, 10-15 cut points should be left according to the age of the tree. Generally, dozens of green leaves that can photosynthesize must be left on the tree after pruning. After shortening the main branches and leaving enough branch points, Alla tunna och svaga grenar på blåbärträdet som växer för mycket, för täta, för svaga och för gamla, såväl som de som växer i orimliga positioner och påverkar trädets form, ventilation och belysning, bör vara direkt avstängda .}
3. When harvesting and pruning blueberries, the auxiliary branches at the bottom must be handled properly. After pruning the main branches of blueberries, all the remaining young and tender upright new shoots should be pinched and topped to remove the growth advantage of the top of the tender shoots and promote the germination of the lower buds. For blueberry trees with weak tree vigor during pruning or with few leaves on the tree after pruning, wait until the main branches are pruned in spring, first keep the thin and weak branches at the bottom, let it use the photosynthesis of green leaves to produce nutrients for the tree body and promote germination. When the new shoots that sprout next grow to 10 to 20 centimeters and have the ability to photosynthesize, then cut off all the thin och trasiga grenar och löv i botten reserverade i det tidiga skedet .
För blåttbärträd som är kraftfulla under beskärning eller har gott om gröna blad efter beskärning, kan du antingen direkt stänga av alla krypande, tunna och trasiga grenar som växer horisontellt i botten, eller så kan du reservera dem för användning för 2-3 veckor och sedan klippa av dem alla
