In apple production, many fruit growers cannot correctly grasp the basic method of twisting the apple tree, resulting in many branches being twisted or have no effect. Therefore, it is recommended that the majority of fruit growers must take appropriate measures to ensure that the tipping techniques of apple trees are properly handled and the following key steps are taken care of:
First, the concept of twisting
Twisting refers to a method in which the new shoot that grows upright and prosperous during the growing season is twisted and twisted about half a centimeter around the base of the shoot, so that the new shoot can be stretched out and then hanged.
Second, the best time for apple tree twisting
Combined with the climatic characteristics of Zhaoyang District and the biological characteristics of apple trees, the best time for the twisting of apple trees in our region is from mid-late to late-June.
Third, the role of twist tip
(a) Control the secondary shoots and erect shoots on the back of the main branch and compete for new shoots.
(b) Accumulation of nutrients to promote flower bud differentiation.
Fourth, pay attention to matters
(A) When the new shoot grows to about 2O-25 centimeters, it begins to twist when it is semi-lignified.
(b) Do not look at the tip to twist and twist the tip to death.
(3) Be sure to twist about 5 centimeters around the base and twist half a turn by hand.
(D) twist the shoots when the branches twist half a circle, so that the new shoots can be extended to the sagging, and should not twist a circle or a few turns to twist branches.
(5) When twisting the tip, only the xylem is injured and the phloem is not injured, which is usually said to not damage the skin.
