Embodiment 3
One apple orchard of Yuncheng Linyi, top fruit sprayer is tall and big in garden, interior thorax covers that close, tree vigo(u)r is partially prosperous.
Shearing procedure:
Before Winter Solstice in winter, for the fruit tree of upward prosperous length in garden, first on trunk, one at 2.5-3m is selected from the bottom up
A major branch is top layer's major branch, as shown in Figure 1, selecting top layer's major branch up on the trunk, and is located at top layer's major branch
One sprig of contraposition is sawed obliquely on the attachment region top of this sprig as undercut, is carried out trimming and is fallen head;Fall head saw mouth
Section part smears consolidant;
The sprig can restrain the growth of lower part major branch, and sprig can be trimmed as needed in growth course, or
Person carries out drawing branch layout, and then is trained medium-sized fruitful branch.
The method for staying sprig to restrain can also be used for needs, side shoot close, that light transmittance is poor is covered in trimming, to open light
According to stable tree vigo(u)r.
Trimming current year, after all trimmings tree vigo(u)r growth balance, tree vigo(u)r it is mad it is prosperous be effectively controlled, fruiting rate and fruit obtain
To raising, effect is very ideal.
The present invention can be used for the various big tree-like fruit trees of hat, be a kind of dynamic pruning method.The present invention falls position and the height of head
The selection of degree, according to the planting density in orchard, tree body height, tree crown space is different and selects the different positions that falls, to reach
Natural equilibrium is suited measures to differing conditions in terms of time, adaptation to local conditions, the effect assumed a posture with branch, is fallen a position and be can be high or low, unrestricted;
When the present invention is used for winter pruning, winter, which falls head, has growth trend to help gesture function, but winter should select a good opportunity and move, and avoid in the bitter winter
Weather.
When falling head trimming for autumn band leaf, have the function of that cutting gesture delays gesture.
The present invention uses oblique undercut, increases wound section, to weaken based on the growing way of sprig, make sprig development by
Limit, is easy to be trained medium-sized fruit-bearing shoot cluster.The sprig is located at positioned at the 90-270 degree orientation of top layer's major branch, is preferably placed at most
The contraposition of upper layer major branch.
Selection for sprig will first choose top layer's major branch, and suitable sprig is found in the upper surface of top layer's major branch,
As staying branch;Sprig cannot be Chong Die with lower layer's major branch, to reach preferable illumination and growth.
The present invention falls head saw mouth section part and smears consolidant, helps wound healing.
The present invention stays branch to restrain, and avoids disposably falling head saw except caused wound rots, so as to cause each master under wound
The production impetus of branch stablizes tree vigo(u)r relatively, avoids directly falling head and causes to rebound.Sprig is left as containing, on the one hand, can inhale
Excessive nutrient water is received, is played a role in the drainage, on the other hand, the excessive growth caused by trimming of other growth sites is prevented, prevents from carrying on the back
The growth of upper branch.
