Pruning technology of big cherry tree in summer bud pruning method is to remove all the strong and luxuriant branches and slender branches near the competitive buds on the main branches, side branches and main branches, and cut the buds at the leaf opening stage. Cut off two buds, leaving one bud, and cut off pests and diseases, waste buds and reduce long fruit branches. By removing buds, useless new buds can be reduced, and nutrition can be concentrated, so that the remaining branches are more comprehensive and full, and the leaves and flower buds are full. It can also improve the canopy lighting conditions and greatly reduce the workload and damage caused by summer pruning.
Twisted branches are mainly long branches that are easy to make a fire on branches or main side branches, such as twisted branches. When the new shoots are semi-lignified, cut off the competitive branches near the main branches and side branches, as well as the strong long branches and upright branches that have room to become side branches or medium and large fruit branches. The twigs are mainly the dense branches on the main lateral branches and fruit branches. Generally, you can keep some fruit branches and don't have too many sparse fruit branches. In the high temperature period, the new shoots with free growth characteristics change their growth direction by taking branches. Tapping easily leads to excessive secondary branches and closed crown. Now, in addition to the shaping of saplings, it is necessary to pick the extension branches of main branches and side branches, and generally do not pick new branches when pruning in summer.
The bare branches with space left on the main branches can be cut with 1~2 knots at the base, which can cultivate small and medium-sized fruit branches. Long fruit branches or long fruit branches can eliminate the apical advantage and promote the formation of short fruit branches. The long position allows the maximum number of buds to stay on the branches and relieves the growth potential of new buds next year. The above is the summer pruning method of cherry introduction. If farmers want to plant high-yield cherries, they must pay attention to the reasonable pruning of fruits, strengthen field management and effectively avoid the occurrence of pests and diseases.
