Fruit trees need high yield and summer shear

Core Tip: Summer shear has a very important role in fruit trees, not only can improve light, promote fruit tree growth, but also promote the formation of fruit tree buds, improve the accumulation of nutrients, lay a good foundation for high quality and high yield in the coming year. So, what are the methods for cutting fruit trees in summer? What should you watch out for when pruning fruit trees in summer?

A. Common methods for fruit trees in summer

The picking up of the heart is generally conducted from August to September. The method is to cut the shoots of the new shoots, leaving 20 cm long, and wait for the second shoot to germinate, and then leave the shoots for 20 cm. Saplings can be nailed to the branches.

The tip of the twist tip can be synchronized with the picking by bending the semi-lignified branches (20-30 cm long) in a direction opposite to their growth direction. It should be noted that the speed of the tip is slow, pay attention to the degree of toughness of the shoots to prevent twitching. This method can control the shoots of new shoots and increase the accumulation of photosynthetic products in the tree.

Curved branches and branches are generally carried out in July and August, so that Xinwang branches can grow downwards or leftwards and rightwards by external forces. They can also be tied to their own branches or to other branch shoots, so that they can change their growth direction. Branches in a circle, but can not be broken.

Ring circumcision, ring cutting, and peeling the skin peel off the phloem of the branch, known as girdling. Only a part of the bast was cut, and those who did not peel were called cuts. The peeled bark is inverted upside-down and then embedded in the original stripping site, and the bandage is healed and called inverted. These measures are all taken in the growing season for the overgrown branches.

The elimination of the long branches by removing the long branches can not only improve the ventilation and light transmission performance of the fruit trees, increase the light, but also strengthen the photosynthesis, reduce the unnecessary consumption of nutrients, and increase the accumulation of tree camps. Note that the cuts should be leveled, leaving no posts and new branches.

The root-broken roots are generally taken from August to September. The method is to use the trunk as the center, open 50 cm deep and 20-centimeter-wide semi-enclosed ditch at the radius of 1/3 of the crown, cut the lateral roots, cut the net roots, and cut the roots to make the joints smooth. Leveling must not damage the main root of fruit trees. The root can be removed by cutting the aged lateral roots and hairy roots.

Deleaching is generally carried out in September. The method is to eliminate dense leaves. Care should be taken to remove the leaves from the fruit trees. De-leaching can improve the illumination of the inside of the crown and the fruit, promote the formation of flower buds, enhance the color of the fruit, and help the fruit tree enter hibernation early.

B, fruit trees summer cut "five taboos"

A bogey straying too early and too heavy too early and too heavy will result in re-emergence of leafy squid, affecting flower bud formation, at the same time reducing photosynthetic accumulation and affecting tree growth. Sparse growth should be performed after the spring shoot is stopped. The sparse amount is about 30% light transmittance under the tree.

The second avoidance of the branch open angle early pull branch open angle will lead to the back of the bar and flowering effect is poor. For the new shoots to be used, the branches can be taken when the wood is half-wooded; the main side branches with the small angle should be opened in the autumn.

Third, avoid the contiguous torsion of the tip of the connecting rod, which affects the illumination. In the same main branch, there are usually 3 to 5 tips for twisting. The advantage of flowering on the back can be used, and the rest should be removed.

4 bogey heavy heart-picked to pick up the heart will lead to re-growth, poor light transmission, poor flowering, should be used as little as possible.

Five bogey evacuation fruit Taiwan auxiliary tip sparse fruit Taiwan auxiliary tip will affect the fruit enlargement, should throw fruit deputy tip, in order to facilitate the supply of nutrients nearest the fruit.

C, fruit trees summer shear matters needing attention

When you cut in the summer, you must vary from tree to tree, and you can't be stereotyped. For example, walnut trees cannot be pruned in summer, and wounds can cause wounds during the growing season, which further weakens the tree vigor and is not beneficial to the growth results of the year or the following year. Grapes are pruned before they are buried in the cold in the autumn.

Summer pruning is usually carried out during the growing period of fruit trees or long-standing branches and leaves, so if you miss a suitable time, it will affect its effect, and sometimes it will have an adverse effect. If new shoots are already lignified, it is difficult to carry out twisting.

Summer pruning is based on the principle of hands-on, dynamic shearing and immovable sawing. It is not possible to go to large branches. It is necessary to leave large branches for winter cutting and remove them. Otherwise, large wounds are caused, which can easily cause rot disease, or give worms and gudgeon insects. Caused living places, resulting in major pests and diseases.
