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 long temperate zone deciduous fruit tree of a kind of life-span.In process of production, some apple tree major branch lazy weight often in the apple orchard of growing up, apple tree major branch growth potential difference is big, or apple tree major branch spatial distribution is inhomogeneous or the dried elongated shoot growth potential in apple tree center is weak.The plant of apple tree major branch lazy weight does not have enough fruit bearing shoot amounts, causes to yield poorly.Apple tree major branch growth potential difference is big, causes the nutrition supply between major branch unbalanced, causes the apple mass discrepancy big, can influence the growth potential that do at the center simultaneously.Apple tree major branch spatial distribution is inhomogeneous, reduces effective result space, causes to yield poorly.The dried elongated shoot growth potential in apple tree center is weak, can influence the equilibrium growth of whole plant, causes that apple production is low, mass discrepancy is big.Pruning method for updating with routine, upgrade apple tree major branch lazy weight, apple tree major branch growth potential difference is big, apple tree major branch spatial distribution bad apple inhomogeneous, that the dried elongated shoot growth potential in apple tree center is weak is tree-like, the trunk shape that is difficult to form standard is tree-like.The employing branches of tall trees bull grafting update mode that has at present, but have grafting cost height, the shaping operating difficulties forms the tree-like problems such as time length of standard trunk shape.

Summary of the invention

Problem at above-mentioned existence, the purpose of this invention is to provide a kind ofly at the tree-like complete crown update method of bad apple that apple tree major branch lazy weight, apple tree major branch growth potential difference are big, apple tree major branch spatial distribution is inhomogeneous or the dried elongated shoot growth potential in apple tree center is weak, it is tree-like and recover tree bulk-growth 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 was except whole major branches, and it is high 1.2～2.7 meters to stay the center to do, and the major branch saw kerf is close to the center and is done, and does not stay the branch stake, and the center is done the top saw kerf and become miter angle, and saw kerf is coated with white glue with vinyl and mixes the universal bactericide;

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

3, the twig that germinates below 1 meter is done at the center of erasing between the budding period;

Spreading angle to 80 when 4, new major branch grows to 25～35 ㎝～90 degree, when major branch grows to 60～70 ㎝, arrange 15～30 on the good major branch selected and remain by spiral escalation, and with fixing spreading angle to 80～90 degree of rope, the center is done the top and is selected and remain healthy and strong, the upright branch of a growth as the dried elongated shoot in center.

Employing the present invention is simple and easy to do, and is can regeneration standard trunk shape apple tree-like through 3 years, realizes that tree body complete crown upgrades and recover tree bulk-growth gesture, and significantly promotes output, the quality level of apple.

Embodiment

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

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

3, the twig that trunk germinates below 1 meter of erasing between the budding period;

When 4, 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 ㎝, do high and dried thick difference according to the age of tree, center, arrange 15～30 on the good major branch selected and remain by spiral escalation, and with fixing spreading angle to 80～90 degree of rope, the center do the top select and remain a growth healthy and strong, upright as the dried elongated shoot in center.The winter dormancy phase, to major branch angle less than 80～90 degree, draw 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 is carried out rich water and extermination of disease and insect pest management.

Claims

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

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

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

(3) twig that germinates below 1 meter is done at the center of erasing between the budding period;

Spreading angle to 80 when (4) new major branch grows to 25～35 ㎝～90 degree, when major branch grows to 60～70 ㎝, arrange 15～30 on the good major branch selected and remain by spiral escalation, and with fixing spreading angle to 80～90 degree of rope, the center is done the top and is selected and remain healthy and strong, the upright branch of a growth as the dried elongated shoot in center.
