What are the mistakes of summer pruning fruit trees?

The right thing to do is:

Should be in late may and early June spring shoots stop growing, the tree according to the situation appropriate cut ring ring (cut), ring (ring) cutting cutting thin tip again after a week, so can not only make full use of sunlight, food-making without article contribute to risk, affect the formation of flower bud.The amount of thinning should be based on the projected area under the tree, and the shadow coefficient of the thinning is generally about 30%.

Thinning objects:

The outer two branches above the head, the inner bore of the thin branch, the back and the cut of the long branch, the branch of the branch and the branch of no space growth.

It is not scientific to pull a branch.

Many fruit farmers in spring to the fruit trees to open the Angle, resulting in the back of a strip, the flower effect is poor.The new tip that is not good to the Angle, should be used in the semi-lignification to take the branch, so as to slow its growth.The Angle of the main lateral branch should be opened in the autumn, in case of the back.

Twist pin shall

Some fruit farmers, no matter how many twigs on the back, increased the amount of branches, and affected the light.Back space larger place, long to more than 35 cm, such as new tip in half lignification (centers to 5 ~ 8 cm) high twist pin, back can make full use of the advantage into flower as a result, and will not affect the light.The same principal twig should not be too much, should be according to the tree body size twist 3-5, the rest of the rest.

A short cut is overweight

The short cut (heavy lifting) will cause the branches to grow again, causing the tree to be more light and less effective.In the production, the short cut should be used sparingly, but only after the thinning of the branches, the leaves of the leafy branches on the branch should be left 3-5 large leaves.

Improper handling of fruit stand.

Some fruit farmers to the fruit-table top cut off one, some pick the heart, some simply remove.These practices violate the rules of the nearby supply of nutrients, causing less nutrients to be produced around the fruit and affecting the growth of the fruit.The correct way is: shake off the top of the fruit table, do not cut off the heart, the supply of nutrients nearby.
