In late May and early June, the main period of summer pruning of apple trees is to control the growth of new shoots and promote the formation of flower buds, which will lay a good foundation for the flowering results of the next year. The mistakes in the easy-to-appearance of apple trees in summer are listed below, reminding farmers to take precautions.
Sparsely too early and too many many fruit growers in the fruit trees after fruiting a large number of sparse shoots, so that the tree under the shadow coefficient more than 40%, so that not only cause the early stop length of squid squid sprouting again, affect the formation of flower buds, and because Sparse large number of leaves, reducing the formation of photosynthetic products, is not conducive to the robust growth of the tree. The correct course of action is to stop the growth period in late spring from late May to early June. According to the condition of the tree, it should be properly girdled. After girdling for a week, it should be used to make full use of the sun to make nutrients and not to promote the development. Bars, affect the formation of flower buds. The number of loosening should be based on the projected area under the tree, and the shadowing coefficient should generally be maintained at about 30% after thinning. The sparse objects were heads with more than two ridges in the periphery, thin branches with dense internal ridges, leggy twigs with back and cut edges, competing twigs on branches, and branches without space growth.
Many branches of fruit growers open branches in the spring, leading to strips on the back and poor flowering results. For new shoots that are not good for angles, they must be taken when they are semi-woody; open angles should be made for the main side branches that are small in angle to prevent backstrips from falling.
Some fruit growers with twisted shoots and no matter how many twisted shoots there are on the back branch, this practice has increased the amount of branches and also affected the light. When there is a large space on the back, when the new shoot grows to 35 cm or more, the high-twist tip is in the semi-lignified part (5 to 8 cm below the top of the center), which can fully utilize the advantages of flowering on the back, Does not affect the light. The same main branch twist should not be too much, should be based on the size of the tree tip 3 to 5, and the rest of all sparse.
Short cuts that are too heavy (short for heavy toppings) will lead to re-growth of branches, resulting in poorer light transmission and poor flowering. In the production, the short cut (re-spinning) should be used sparingly, and only the branches that cannot be flowered after the branching are feared to be short-cut, and the short-cut and then removed 3 to 5 leaves are effective.
Some fruit growers had improper handling of their shoots and some fruit growers cut one for the top of the fruit counter, some topping, and some simply removed. These practices violated the law of supply of nutrients nearby, resulting in less nutrients around the fruit and affecting fruit enlargement. The correct course of action is to dump the fruit shoots at the top of the table and not to cut it or pick it up in order to supply nutrients to the nearest place.
