After the early-maturing apples such as Mei Ba, Jura, etc., many fruit farmers think that they can breathe a sigh of relief. In fact, this concept is not allowed. The fruit trees are the same as people. The “post-natal†is very weak, and it also needs to “complement the bodyâ€. Strengthen management:
Pest control In this year, some apples in the fruit area have rainy weather when harvested, but the harvesting period can not spray, creating conditions for the occurrence of pests and diseases. In this period, we must first check the rot, dry rot and beetle, red spider When the occurrence of pests and diseases occurs, timely prevention and control.
Supplementary nutrition after apple harvest, should be timely supplemented with nutrition. It can be dried with foliar fertilizer, or combined with prevention and treatment of early defoliation and red spider, etc.
There are some differences in the management of late management of early-maturing apples and late-ripening apples. The growth characteristics of mid-early ripe apples are spring shoots, weak summer shoots, and autumn shoots. After the apples are harvested, the burden on the trees is reduced, but in addition to the rainy autumn, from mid-August to mid-September, the autumn shoots are prosperous. If left unchecked, the 30~50 cm erect branches can grow to 1.5 meters or even 2 meters. Exceeding the thick thumb, causing too much nutrient consumption, causing serious problems in the next year, and the tree is weak.
1. For the main branch that is too low from the ground, the mopping branches on the main branch, and the large branches on the middle and upper part of the severely closed overlapping branches should be removed early, which is beneficial to the control of the crown and stable flowering, and is in the process of In the autumn shoot growth period, the wounds heal quickly, which is conducive to the safe wintering of the fruit trees.
2. For the branches on the back, the strong branches do not move. The Wangzhi, which is used for the main and side branches, starts from the base and turns the branches, weakening its prosperity, and the virtual branches are turned, but the base does not move, so that it rejuvenates. .
3, do not prematurely evacuate the pinning branch, and decide whether to use it or to use it in late September. For other branches on the back of the main branch, if the main and side branches are not used for production, they will be removed.
The branching of the branch with a long length of the new branch that has not been completed in the previous stage and the main bare belt has to be grasped, because it is in the early stage of the growth of the autumn shoots, the shape is fast and the healing is fast.
Autumn Shiji Fertilizer entered September, and the autumn shoots stopped growing. The fruit trees entered the third peak of root development. Fertilization in this period was beneficial to the accumulation of nutrients and to the healing of root wounds in fertilization.
