One, improperly targeted ringing Suitable for girdling should be a tree with strong callus ability, flowering difficulties, age-incompetent results, and strong growth potential. Must not be irrespective of species and tree vigor. Second, improper ringing time Appropriate circumcision period is from late May to early June, when fruit bud physiological differentiation begins. Early circumcision, affecting the normal growth of new shoots, circumcision too late (after July), when the wound is difficult to heal, easy to die. The circumcision was too early and the effect of flower promotion was poor. III. Improper circumcision The girdling should be carried out on the smooth part of the central stem that is 15 to 30 centimeters from the central stem or lateral branches, and must not be girdled on the trunk to prevent the extreme weakness of the tree vigor, resulting in adverse consequences such as low yield, poor quality, and short economic life. IV. Irregularities After girdling, attention must be paid to alignment and stripping. Do not make it misaligned. Make sure that the width of the strip is consistent and that the incision cannot be burred to facilitate wound healing. Five, knife wounds too deep When circumcision can not be exerted too much force, it is required to cut only the phloem, not to damage the formation layer and xylem, in order to facilitate the healing of the wound, to avoid the formation of a black injury ring in the branches after injury to the xylem, affecting the firmness of the tree skeleton structure. 6. Exfoliate too wide The appropriate girdling width is 1/15 to 1/10 of the diameter of the stripped part of the stripped part, and the maximum width is not more than 5 mm, rather narrower than wide. Seven, multiple ringing Only one ring can be circumscribed on the main branch or lateral branch. It is not possible to circumcise both the lateral branch and the circumscribing mother branch, and it is impossible to excuse two or more legs simultaneously on one branch. For trees or branches that are still more prosperous after girdling, it is advisable that at the beginning of July, when at least 1/2 of the first circumcision wound has healed, perform a second time at 3 to 5 cm below the last excision. Gingival peeling and peeling should be narrower than the first peeling. Eight, the amount of peeling is too large The amount of peeling of each tree should be determined according to its growth potential, and should not exceed 2/3 to 1/2 of the total number of stem branches of the whole tree, leaving some branches without girdling, so that the root system can still obtain a small amount of photosynthetic products, so as to avoid Excessively weakened tree vigor, resulting in premature decline of tree vigor. Nine, after peeling the applicator Some growers are concerned about the infection of rot bacteria in the girdling area. Therefore, some drugs such as Formamide and Aspen are coated on the excision area, resulting in dead trees (branches). The excision wounds should not be randomly coated to facilitate the smooth healing of the wound. Tenth, improper management after stripping After girdling, if the peeling does not heal within one month, use plastic film dressing to promote the rapid healing of the wound; after girdling, the management of fertilizer and water in the orchard should be strengthened, and 2-3 times in the growth period plus spray 0.4% to 0.5% The urea solution and 0.2% to 0.4% of potassium dihydrogen phosphate, in order to supplement the tree nutrition; when the amount of flowers is large, the next year flowering period should be strictly sparse, so that the tree is a reasonable load to maintain its strong tree vigor.

Fruit trees erroneous zone
In May and June, the yew was applied to fruit trees with low yield and prolonged growth, and the photosynthate produced by the leaves was used more for the formation of flower buds by truncating the nutrient transport channels in the branches. However, if such measures are taken improperly, it will result in debilitating tree vigor, which will reduce the resistance of the tree to disease and stress, and lead to the occurrence of diseases such as rot disease. For girdling of fruit trees, trees should be used to avoid the following errors.
