Why should fruit trees be careful when carving buds? Which bud should be engraved and which bud should not be engraved? Without the guidance of technicians, some fruit farmers carved the fruit trees in a mess. They don't know which bud is better to carve. In the end, it backfired. The carved shoots not only failed to blossom and bear fruit, but also grew many bare branches. Therefore, fruit trees will randomly pull out the messy branches of trees, which will not only affect the growth and lighting of trees, but also waste nutrients, bring trouble to pruning and shaping, and delay the fruiting period.

Basic knowledge of bud carving

According to the growth law of fruit trees, there are generally two periods suitable for bud cutting. One is the time to make long strips, that is, the time to make long branches. At this time, carve as soon as possible, preferably around the vernal equinox, that is, in mid-March. Cutting long branches early can increase the number of branches of young trees and expand the crown. The other period is around Tomb-Sweeping Day, but the specific germination time should be flexibly adjusted according to different phenological periods in different regions, and it cannot be generalized.

Before cutting buds, we should choose a special cutting knife or saw blade to cut buds, and often disinfect them to avoid infecting fruit trees. When selecting the bud cutting saw with large and medium serrations, the serrations of the small steel saw blade are too small, which easily affects the operation. If the workload is heavy, you can use "substitute bud cutting" 1:50 times solution to spray on the corresponding position of branches, which saves manpower, time and efficiency.

When cutting the flower bud, according to the position of the flower bud on the branch, cut off the cortex before and after the flower bud horizontally or vertically with a sterilized small steel saw blade or knife. Dry and newly planted seedlings should be cut early and then cut, and the cortex should be cut to xylem before germination to intercept nutrients and promote growth. Cut the cortex before germination, so that the wound can reach the xylem, thus intercepting nutrients, promoting the growth of short branches and forming flower buds more easily. At the same time, in order to inhibit the growth of back buds, the cortex can also be cut after buds, so that the phloem can be cut to the depth of xylem.

Places with dense germination should be properly separated. Don't dig up every bud. Generally follow the principle of "one every two minutes"; In the place where the buds grow sparsely, the spacing of cutting buds should be smaller to lengthen the branches and expand the crown. For example, the first to fourth buds under the extension branches of the central trunk grow vigorously, so the second, third and fourth buds can easily form competitive buds. Therefore, it is necessary to carve behind these three buds to weaken their growth and balance the tree structure.

Annual branches shall not be carved within the range of base 10 cm, branches 15 cm, the middle and both sides of anticline, and the back of bud. This will help to disperse and slow down the growth and promote the growth of short branches. If combined with ring cutting, it is easy to form flower buds and make fruit trees blossom and bear more fruits. Cut more buds on the main branches, but pay attention to the spacing of buds. Generally speaking, the amount of cutting buds accounts for about half of the total number of buds, so as to promote the number of branches, control the thickening of branches and form long-term fruiting branches.
