Abstract

The invention provides a full crown regenerating method of a defected apple tree form. The method comprises the following steps of: 1, sawing off all the main branches 25-35 days before sprouting in the period of dormancy of apple tree, remaining the central trunk by the height of 1.2-2.7 m, wherein the saw bite of the main branch is close to the central trunk, the saw bite at the top end of the central trunk is at an angle of 45 degrees, and the saw bit is coated with a white emulsion mixed with a broad spectrum bactericide; 2, spraying lime sulfur mixture having a baume degree being 7-10 to the central trunk; 3, removing branch buds sprouting within 1m of the central trunk in the sprouting period; 4, when the new main branches grow up to 25-35cm, opening by an angle of 80-90 degrees, and when the main branches grow up to 60-70cm, selectively remaining 15-30 good main branches and fixing the opening angle in the range of 80-90 degrees by a rope; and selecting a strong, vertical branch as the extension branch of the central trunk at the top end of the central trunk. The full crown regenerating method is simple and feasible; with the method, standard trunk tree form can be obtained in 3 years; full crown regeneration of the tree body and the recovery of tree body growth vigor can be realized; as a result, the yield and the quality level of apples can be obviously improved.

Description

The tree-like complete crown update method of bad apple

Technical field

The present invention relates to the tree-like update method of a kind of bad apple.

Background technology

Apple is longer temperate zone deciduous fruit tree of a kind of life-span.In process of production, often some apple tree major branch lazy weight of growing up in apple orchard, apple tree major branch growth potential difference is large, or apple tree major branch spatial distribution is uneven or apple tree center dry elongated shoot growth potential is weak.The plant of apple tree major branch lazy weight, does not have enough fruit bearing shoot amounts, causes and yield poorly.Apple tree major branch growth potential difference is large, causes the nutrition supply between major branch unbalanced, causes fruit quality difference large, can affect the growth potential that center is dry simultaneously.Apple tree major branch spatial distribution is uneven, reduces effective result space, causes and yield poorly.Apple tree center dry elongated shoot growth potential is weak, can affect the uniform growth of whole plant, causes that apple production is low, mass discrepancy is large.By the method that the pruning of routine upgrades, renewal apple tree major branch lazy weight, the bad apple that apple tree major branch growth potential difference is large, apple tree major branch spatial distribution is uneven, apple tree center dry elongated shoot growth potential is weak are tree-like, and the trunk shape being difficult to formation standard is tree-like.The employing branches of tall trees bull grafting update mode had at present, but it is high to there is grafting cost, shaping operation difficulty, forms the problems such as the tree-like time length of standard trunk shape.

Summary of the invention

For above-mentioned Problems existing, the object of this invention is to provide a kind of complete crown update method tree-like for apple tree major branch lazy weight, apple tree major branch growth potential difference is large, apple tree major branch spatial distribution is uneven or apple tree center dry elongated shoot growth potential is weak bad apple, it is tree-like and recover Growth status gesture that the present invention can form the trunk shape of standard fast.

The present invention is achieved in that

1, before apple resting stage rudiment 25 ~ 35 days, saw, except whole major branch, stayed center to do high 1.2 ~ 2.7 meters, and major branch saw kerf is close to center and is done, and do not stay branch stake, center is done top saw kerf and become miter angle, and saw kerf is coated with white glue with vinyl and mixes universal bactericide;

2, the lime sulfur of spray 7 ~ 10 ripple magnesium degree is done at center;

3, between the budding period, the twig of less than 1 meter germinating is done at the center of erasing;

4, spreading angle to 80 ~ 90 degree when new major branch grows to 25 ~ 35 ㎝, when major branch grows to 60 ~ 70 ㎝, 15 ~ 30, excellent major branch of selecting and remain is arranged by spiral escalation, and with fixing spreading angle to 80 ~ 90 degree of rope, center is done top and to be selected and remain the elongated shoot that a robust growth, upright branch do as center.

Employing the present invention is simple and easy to do, gets final product regeneration standard trunk shape apple tree-like through 3 years, realizes tree body complete crown and upgrades and recover Growth status gesture, and the remarkable Yield and quality level promoting apple.

Embodiment

1, before apple resting stage rudiment 25 ~ 35 days, stay center to do high 1.2 ~ 2.7 meters, center was done top saw kerf and is become miter angle, and in trunk straight place, saw removes; Saw is except whole major branch, and major branch saw kerf is close to center and is done, and does not stay branch stake; Saw kerf painting white glue with vinyl is mixed universal bactericide and is protected.

2, the lime sulfur of spray 7 ~ 10 ripple magnesium degree is done at center, prevention and elimination of disease and pests;

The twig of less than 1 meter, trunk of 3, erasing between budding period germinating;

4, when new major branch grows to 25 ~ 35 ㎝, with biapiculate bamboo tooth pick support branch, spreading angle to 80 ~ 90 degree, when major branch grows to 60 ~ 70 ㎝, height and dry thick difference is done according to the age of tree, center, to select and remain 15 ~ 30, excellent major branch by spiral escalation arrangement, and with fixing spreading angle to 80 ~ 90 degree of rope, center is done top and to be selected and remain the elongated shoot that a robust growth, upright branch do as center.The winter dormancy phase, to major branch angle less than 80 ~ 90 degree, carry out drawing to this angle with the rope made of hemp or cloth.

5, field management is according to the Routine Management program in apple orchard, and science carries out rich water and extermination of disease and insect pest management.

Claims

1. the tree-like complete crown update method of bad apple, is characterized in that step is as follows:
