Abstract
The invention discloses a pummelo low-position multi-head seeding changing and single-axle hierarchic excellent quality prolificacy technique. The technique comprises the steps of firstly selecting a branch that has strong growth vigour and is in the centre as a centre axis, cutting the branch at a position of 50-100cm, extracting the tip of the branch and then culturing the branch to be a central branch, selecting 2-3 different azimuths at the lower section of the central axis, preferably the staggered branches to cut, and culturing to be a first layer of main branches, culturing the tree crowns in a single-axle hierarchic manner, directionally and artificially inducing for formation by means of bud picking, core picking and traction, deliberately maintaining the middle and short branches in the tree crowns as much as possible, and culturing to be the braches bearing fruits, and finally accelerating to bloom early and to bear more fruits. The invention uses ready limbs of a tree as skeletons, changes the seeding for multiple heads at low position and shortens the replacement cycle. The tree crown recovers quickly and bears fruits early. The invention uses a single-axle hierarchic manner and the central branch has obvious advantages. The main branches are distributed hierarchically, and the master-slave relation is definite. The technique avoids the competition among multiple heads and accords with biological law of pummelo tree.
Description
Technical field
The present invention relates to the culture technique of a planting fruit-trees, relate in particular to a kind of sweet shaddock low level bull and change kind and single shaft layer-stepping high grade producing technology.
Background technology
The honey shaddock is a fruit variety of China, and still, for a long time, people confuse the cultivation management of sweet shaddock with cultivation management in common orange tree.Because the grapefruit height is big, requires the structure proportioning of skeleton branch will have levels and distance, could satisfy the requirement as a result of grapefruit.Grapefruit mainly is in leaning on, the brachyplast result of bottom, and grapefruit all is to set based on the clump shape in the past, cause the tree crown branch to be distributed in the same aspect at top slightly, in having caused, bottom brachyplast depauperation and can't the result, even because of interior thorax withered, malnutritive and dead, cause bearing basal shoot quantity to reduce, directly influenced the output of shaddock.And prior art adopts the high-grafting way when usually inferior fruit tree being carried out breed improvement more, and after the changing-over, a plurality of ends of the branch are competed simultaneously, advance side by side, and the growth of clump shape, leaf curtain layer focuses mostly on same plane, and the tree bough is many, and outer empty in close, output is humble.
Summary of the invention
The objective of the invention is to change kind and single shaft layer-stepping high grade producing technology for the sweet shaddock low level bull that overcomes the deficiencies in the prior art and provide a kind of output to improve a lot.Its concrete grammar is:
1, the low level bull is changed kind: select growing way stronger, the branch that the position is placed in the middle, as central shaft, carry out cut-grafting at the 50-100cm place, take out and cultivate after a while for the center branch, at the central shaft hypomere, select 2-3 different azimuth, branch of giving birth to preferably straggly carries out cut-grafting, cultivates to be the ground floor major branch, if former trunk is too high, below 100cm, there is not branch, can adopt the two bud cut-graftings of central shaft, and can be on trunk side grafting 1-2 bud, take out after a while, it is the center branch that one on the central shaft strong bud is cultivated, the branch that side grafting is extracted out on another bud and its underpart trunk is cultivated into major branch, if when the following major branch number of 100cm can not reach 2-3, can take the center branch is in time plucked core or cutting back, from the mitogenetic side shoot of center branch, replenish and cultivate not enough major branch, so just can finish the selection cultivation of ground floor major branch at lower position.
2, single shaft layer-stepping tree crown is cultivated: change first and second year after planting, it is the key that single shaft layer-stepping tree crown is cultivated, at first, should center branch and the apolegamy of ground floor major branch is suitable, and adopt bud picking, pluck core, means post-directed training such as support is drawn, traction, second and third year, continue to adopt artificial induction's means that are shaped, adjust major branch angle and orientation, coordinate the balanced growth of each skeleton branch, meanwhile, in the tree crown the middle brachyplast that gives birth to hold as far as possible and stay, and cultivate and to be bearing basal shoot, impel precocity flower, many results;
Along with the increase of the age of tree and the needs of cultivation condition, can be apart from ground floor major branch 80-100cm place, cultivate 2 boughs again as second layer major branch, but should notice that second layer major branch can not overlap with the ground floor major branch, its growing way and mitogenetic angle can not be greater than the ground floor major branches.
The advantage that adopts the present invention's honey shaddock low level bull to change kind and the original grapefruit of single shaft layer-stepping high grade producing technique improvement is:
A, the limb of utilizing tree to be embodied as are skeleton, and the update cycle has been shortened in the changing-over of low level bull, that tree crown recovers is fast, the result early.
B, employing artificial induction shaping technique make tree body skeleton branch according to the cultivation requirement, and it is more reasonable to distribute, and growth is more coordinated.
C, single shaft layering, the center branch accounts for clear superiority, and each major branch is distributed with level, and master slave relation is clear and definite, avoids the bull competition, and close unrest is unordered.
D, conform with the biology rule of grapefruit self.
By to the transformation in 600 mu of shaddock inferior gardens and the demonstration of this technology, now obtained tangible benefit.Comparison is according to shifting to an earlier date the 1-2 annual bearing, and per mu yield is brought up to more than 2000 kilograms for 500 kilograms by original less than.
Embodiment
Embodiment 1, follows these steps to carry out:
(1) the low level bull is changed kind: select growing way stronger, the branch that the position is placed in the middle, as central shaft, carry out cut-grafting at the 50cm place, take out and cultivate after a while for the center branch, at the central shaft hypomere, select 2-3 different azimuth, branch of giving birth to preferably straggly carries out cut-grafting, cultivates to be the ground floor major branch, if former trunk is too high, below 100cm, there is not branch, can adopt the two bud cut-graftings of central shaft, and can be on trunk side grafting 1-2 bud, take out after a while, it is the center branch that one on the central shaft strong bud is cultivated, the branch that side grafting is extracted out on another bud and its underpart trunk is cultivated into major branch, if when the following major branch number of 100cm can not reach 2-3, can take the center branch is in time plucked core or cutting back, from the mitogenetic side shoot of center branch, replenish and cultivate not enough major branch, so just can finish the selection cultivation of ground floor major branch at lower position.
