At the same time, the pruning of fruit trees is also the guarantee of fruit tree harvest.
In order to fruit trees can achieve early fruit, early yield, yield stable yield.
Today we come together to learn what time to prune apple trees and how to prune.
Apple tree pruning time apple tree growth rate is relatively slow, so it is not easy to grow new branches, especially after the results of the tree, the pruning should pay extra attention to, generally in the winter after the fall of the leaves in the spring before the germination of pruning, in the apple tree is completely into the stage of non-growth pruning, can reduce the other diseased and dead branches, dead branches to consume the plant's nutrient needs, and also does not affect the apple tree! Winter and the next year's germination, on the contrary, can also make the branch insulation, and promote branch bud differentiation.
Apple tree pruning method apple tree trimming young shoots apple tree pruning techniques, the general apple varieties of branches in the back of the buds are not easy to sprout, especially slow to put the branch is often "bare legs branch".
In order to promote the need for branching parts of sprouting twigs, reduce the bare legs, should be at the end of March to the beginning of April, in need of sprouting buds to do above or in front of the 0.5 cm with a sharp knife or a small saw blade to wound the xylem 1/4-1/3.
With this will be the center of the main branch of the competition, the buds, the main branch and the auxiliary branch of the back of the buds to key, so as not to sprouting twigs, waste of nutrients, disruptive tree shape.
Apple tree hat pruning apple tree pruning techniques, in mid to late August, the apple tree auxiliary branches on the new shoots, in the spring and fall shoots at the junction of the blind joints hat cut, but also can be - some of the over-exuberant perennial slow release branches in the junction of the first and second year of life hat pruning, Marshal system apple is not suitable for hat.
Specific operation, should grasp the following method: strong auxiliary branch head and large side branch head all cap treatment, and some of the weaker long put branches and mediocre branches are selected to wear a dead cap.
Additionally, all levels of backbone branches and extension of the head is generally not suitable for cap pruning.
Apple tree pruning pruning apple tree pruning techniques, around mid-September, on the inside of the ineffective branches, overlapping branches, cross branches, long branches, competing branches and other thinning and retraction, in order to clean up the inside of the branch and the current year's branches as the focus of the pruning should not be too much.
And in the fruit harvest 15 to 20 days before, the tree on the upper part of the dense branches, trailing skirt branches and peripheral clusters of branches, according to the situation with the leaf retraction or thinning.
The diameter of the thinning and retraction cuts in this period should not exceed 3 centimeters.
Apple tree common pruning apple tree pruning techniques, for too prosperous age of the tree does not bear fruit, can be delayed until after the germination of the winter shearing, in order to ease the tree.
The more prosperous trees in addition to the backbone branches winter shearing, other branches are delayed until after germination, in order to ease the branch potential.
Entering the fruiting period of the tree according to the target yield, such as the amount of flowers is too much, can be cut off part of the middle and long flowering branches, scaling down the string of flowering branches, or thinning out the weak and short flowering branches, in order to reduce the amount of flowering branches, to increase the number of preparatory branches.
Apple tree pruning precautions want apple trees to bear more and bigger fruit, generally only in the winter pruning is not enough, but also in the fruit in time to comb the fruit, you can overgrowth of dense removal, otherwise it will affect the growth of the apple tree, resulting in most of the fruit are growing smaller, and will reduce the yield.
