Different time and different methods of pruning will affect the peach tree's tree vigor, yield, quality, quality of the results, the rate of displacement of the resulting parts and the resulting length of life, and so on, so do not underestimate the winter cut peach.
Grasping the winter cutting time Peach winter cutting should be carried out from early December to late February. Pruning prematurely or too late will result in substantial loss of tree nutrients, affecting tree vigor, and adversely affecting flowering and fruit setting.
Pay attention to the characteristics of varieties Peach trees are divided into two categories of northern and southern varieties, and some northern varieties are prone to frost damage, so the southern varieties can generally start winter cutting in the early or late December, while the northern varieties are the most It is better to miss the coldest period in January, and it is better to perform the winter cut in the middle of February.
Pay attention to the method of winter shear peach tree is a typical stone fruit trees, the flower buds are pure flower buds, lateral, so the peach tree pruning mainly to the short cut, thinning and shearing supplement. In addition to the short-fruit-bunch branches of Peach trees growing year-round, all other branches were trimmed. The short fruit branch of the bouquet is thrown or sheared, and all kinds of backbone branches, extension branches, and upright competition branches under the clipping can be sheared. The result is too large, too long, too weak, and the result is that the branch group can be properly shrunk. .
Grasp the degree of pruning First, trim according to the cultivation area. In regions with low annual precipitation, the growth of peach twigs is small, and only heavy and short cuts can both produce good fruit and produce good shoots.
Second, pruning is based on the breed group. In the southern group, the tree posture is relatively relaxed and the growth potential is relatively moderate. Generally, the degree of truncation should be heavier when pruning, and the results of medium and long fruiting branches should be left. Northern tree species are more erect and have more vigorous growth potential. Lighter, should stay in the middle, short fruit branches and short fruit branch results.
Third, pruning is based on the type of shoot. For extension branches, the degree of pruning should be based on the principle of multiple branches and no baldness at the base. Generally, after various types of extended branches are trimmed shortly, the lateral buds on them are germinated one after another, and the long fruiting branches, middle fruiting branches, and short fruiting branches grow from top to bottom. Only the most basic 5 cm buds do not germinate and become buds and shoots. The most appropriate for the short cut. For leggy branches, except for the cultivation of lateral branches, lateral branches and medial branches, and the cultivation of branches in bald parts of the crown, the remaining legumes were all removed from the base.
For the leggy result branch, it should generally be short cut, let it knot 3 to 4 fruits, and grow a number of long, medium and short fruit branches, will be cultivated into the result group or the result of the branch group, can be many years of continuous results. For long fruiting branches, the fruit should generally be heavier than the shorter ones, so that they will have 2 to 3 fruits and grow 2 to 3 fruiting branches, and they will be cultivated into fruiting branches for 2 to 3 years. . For the fruiting twigs, they should generally be heavier than the long fruiting twigs to make them 1-2 fruit and issue 1 or 2 fruiting branches to maintain the results for 2 to 3 years. For short-fruit branches, they should generally be heavier than the middle-fruit branches to make them tie one fruit, or to avoid the result of the year, and grow one fruit branch to maintain the results for 1 to 2 years or longer.
For short fruit-like branches, it cannot be short. Such fruit branches in northern cultivars can produce good fruit, while fruit cultivars in southern cultivars generally should be removed from the base. For the secondary shoot, born in the lower part of the extension branch, the result can be shortened, while the secondary shoot, which was born in the leggy branch and the leggy fruit branch, was cut off with trimming.
