First of all, the roots of fruit trees have stripes. First of all, we should pay attention to whether there are pests and diseases in the tree. It is the root nutrition that can't be transported to the treetops and branches and leaves normally, which leads to excess nutrition in the heel, so there will be stripes. At this time, it is necessary to find pests and diseases in time and get rid of the diseases. If the wound is too big, one or two branches should be left to bridge the upper part of the wound to alleviate the nutritional needs of the upper part.
Second, if there are no pests and diseases on the tree, it means that the pruning was too heavy last winter, which led to the failure of normal consumption of nutrients in the upper part and the branches at the roots will fall off. At this time, the root branches should be removed in time, and the upper branches should be twisted, pulled and looped, so as to strengthen summer management and make the new branches bear fruit as soon as possible. Winter management can reduce the pruning amount and alleviate the tree potential. Don't pick all the new ones, it will damage the roots of fruit trees, or pick another one next year.
Third, if the above two items are excluded, we should consider whether the tree is overweight. Some fruit farmers use the method of cutting trees around to increase the flower quantity and yield in the coming year, which leads to the failure of root nutrition to be transported to branches normally, so as to alleviate the tree potential and increase the flower quantity! In this way, the heel will take a risk. At this time, you can leave him alone and let him grow. Just remove it when managing fruit trees in winter. Of course, it is best not to circumcise trees, because this will promote the senescence of fruit trees, reduce the ability of fruit trees to resist pests and diseases, and turn strong trees into weak trees! The correct way is to circumcise the fruiting branches to increase the amount of flowers. After two years of fruiting, the branches will weaken, just go back to the moon or cut off the newer branches!
4. Dwarf seedlings also have long roots, mainly because the roots of dwarf seedlings are developed, but there are grafted branches at the grafting place, which inhibits growth. This grafted branch inhibits nutrient transport of root system for a long time, which leads to fruit tree weakness and dwarfs the fruit tree. Therefore, the excess nutrition in the roots will be taken off, and it is ok to dispose of it in time!
The above four points, I hope to solve everyone's confusion, Apple management problems, we can pay attention to private letters and communicate with each other! Thank you for your support!
