The old plastic surgery is straight, and the blind joint is not removed. Generally, it takes two years to form, with no taper and poor load. In this way, it is easy to stagger, so scaffolding is needed for cultivation. Its advantages are fast molding, good ventilation and light transmission, high yield, good quality and good coloring. However, this pruning method is a combination of centripetal advantage and top strength, and it is difficult to restrain the top advantage and achieve balance. With the growth of tree age, the lower branches are easy to weaken, the fruit is small, the quality is poor, and the maturity is prolonged. Discontinuous branching group is easy to bare legs in the lower part.
How to balance the trunk shape of peach trees? The following four methods can basically be solved.
First, the curve rises.
It can grow upward through artificial small bends with short cutting in winter and coring in summer, which obviously inhibits the advantages of the top end, makes the middle and lower parts stronger, increases the taper and increases the load, and will not be staggered even without shed cultivation. In the process of shearing and plastic surgery in winter, we can't leave the autumn skills of bone cultivation to prevent blind joints. If the upper part 1.5~2 feet is thin, there will be no bearing branches left, and if the upper part is thick the next year, there will be a load.
Second, the upper grasp is flat (bud), the lower grasp is full (bud), and the middle is not fine (bud).
It mainly uses the heterogeneity of buds to balance the potential of trees up and down. Cutting in winter, try to choose withered buds to update branches. When cutting in summer, it is difficult to see the buds in the axils of upper, middle and lower leaves sprout strong branches. Therefore, the new shoots of strong branches are re-cored or shortened, leaving 2-3 inches of buds in the upper part, 3-4 inches of buds in the middle part and 4-6 inches of natural buds in the lower part, and they become good branches. The shorter the pile, the weaker the tension, and the longer the pile, the stronger the tension, which is a good way to control the up and down.
Heading in March and September will reduce the storage nutrition of the corresponding roots and weaken the top advantage of the next year.
As we all know, when autumn shoots stop growing and enter the storage nutrition stage, the best effect is to lose their heads 10 days before stopping growing. Without branches and leaves, there will be fewer root storage camps and the top advantage will be obviously weakened.
Fourth, according to the size of space, the lower part is reserved for thickening and fruiting branches.
Some peach farmers call it selling branches. The longer and larger the branches are, the faster the lower trunk thickens, which is beneficial to the increase of taper and load and the balance of up-and-down growth. However, the angle should not be too small, with 85~90 degrees as appropriate, and it is more reasonable to keep it in the next year.
The four methods are indispensable, which can make your peach tree basically balanced up and down, the taper is getting bigger and bigger and the load is getting bigger and bigger. You can cultivate with scaffolding, or you can cultivate without scaffolding at all, which can achieve high yield, high quality and stable yield every year.
