Description

Technical Field

[0001] The invention relates to the technical field of fruit tree cultivation, in particular to a method for cultivating kumquat hedge wall type layered fruit-hanging trees. Background Art

[0002] In fruit tree cultivation and production, there are many commonly used tree shapes. Depending on the type and variety of fruit trees, the natural environment of the planting site, the planting distance, the planting method, the management level, etc., the tree shapes adopted are also different. The common tree structures in production and the commonly used tree shapes of major fruit trees are: central trunk shape, non-central trunk shape, hedge shape, trellis shape and other types. Generally speaking, in order for the fruit trees to eventually form a better fruit-bearing tree shape, it is generally necessary for the planting staff to pay attention to the growth of the fruit trees at all times and prune the fruit trees in time to keep the fruit trees in a better fruit-bearing tree shape. In this process, the experience requirements of the planting staff are relatively high, and the pruned fruit-bearing tree shape will be inconsistent due to the growth form of the fruit trees. Kumquat pruning and branch management have become bottleneck problems restricting standardized production. Summary of the invention

[0003] In order to solve the technical problem in the prior art that the growth forms of fruit-bearing trees are different and not uniform, the present invention provides a method for cultivating kumquat hedge wall-type layered fruit-bearing trees.

[0004] In order to realize the above technical scheme, the present invention provides a method for cultivating a golden orange hedge wall-type layered fruit-bearing tree, comprising the steps of:

[0005] S1: Seedling selection: Choose 2-3 year old container seedlings or strong seedlings with soil balls, with a trunk diameter greater than 1 cm at 10 cm above the grafting point;

[0006] S2: Setting of columns: Before planting, columns and four layers of iron wires were set up. A column was set up every 5m in the longitudinal direction and every 2.5m in the horizontal direction. The column was 3.2m high and buried 0.6m in the soil. Four layers of iron wires were pulled between each column. From bottom to top, the first layer of iron wires was 0.7m away from the ground. Then, a layer of iron wires was set up every 0.4m, for a total of four layers. After the setting was completed, 5 seedlings were evenly planted between every two columns.

[0007] S3: Planting of seedlings: After selecting the seedlings, plant them before spring buds. Before planting, fill the planting ditch with organic fertilizer in advance, and plant them according to the spacing of 1m between plants and 2.5m between rows. After planting, when the top of the strong seedlings is about 5cm away from the first wire, prune them to promote branching. After pruning, set up a support pole. After the branches are formed, tie the central trunk to the support pole to make it grow upright. When the two side branches grow to about 35cm, pinch them to promote the germination of the second-level side branches. When they are mature, pull the branches and tie them to the wires on both sides to make them grow horizontally. After setting four layers in each layer, pinch the tops to control the growth of the trees.

[0008] S4: Management during the growth of lateral branches: After pulling the branches, the lateral branches grow horizontally. When the secondary lateral branches have a certain length, pull the branches to make them grow vertically with the lateral branches. Leave 3 tertiary lateral branches evenly on the secondary lateral branches, and leave 2 fruiting branches on the tertiary lateral branches. When the length of the lateral branches reaches 0.5m, pinch the tops to control the growth of the lateral branches.

[0009] S5: In the early spring of the second year, uniform pruning is carried out, bud fertilizer is applied, and the third-level side branches are shortened to promote branching, leaving two branches that promote branching, and cutting off the excess branches;

[0010] S6: At the end of the third year, the cultivation of hedge-style layered fruit-bearing tree shape is completed, the tree height is controlled at 2m, the width of the hedge-style fruit-bearing layer is 0.8m~1.2m, there are 2 side branches every 40cm on the central trunk, 5 secondary side branches are evenly distributed on the side branches, 3 tertiary side branches are left on the secondary side branches, and two fruiting mother branches are left on the tertiary side branches. The branches are distributed in a hedge-style.

[0011] Further, in step S3, each kumquat tree is provided with a total of four layers of side branches, each layer of side branches has two sections of side branches, and the whole tree has a total of 8 side branches. Each side branch has 5 secondary side branches evenly grown on both sides of the side branch, and the whole tree has a total of 40 secondary side branches.

[0012] Furthermore, when new shoots grow on the secondary side branches, leave 3 tertiary side branches on each secondary side branch so that the tertiary side branches grow evenly on the secondary side branches, and the whole tree has a total of 120 tertiary side branches.

[0013] Furthermore, when new shoots grow on the tertiary side branches, leave 2 fruiting mother branches on each tertiary side branch so that the fruiting mother branches grow evenly on the tertiary side branches. The whole tree has a total of 240 fruiting mother branches, each of which can have 1.5 fruits, ensuring that the whole tree can produce 360 ​​fruits.

[0014] Furthermore, in step S2, the row spacing can be selected as 3 meters and 3.5 meters according to the mechanized farming mode.

[0015] Further, in step S4, after pulling the branches, the branches are tied to make the side branches grow horizontally, and the positions of the secondary side branches sprouting on the side branches are controlled by bud carving or germination to ensure uniform growth of the secondary side branches, while controlling the number of secondary side branches on each side branch to 5.

[0016] Furthermore, in the hot summer and autumn seasons, spray 25 mg / L GA3 on the branches and tips of young trees when they are 80% mature, and apply high-nitrogen fertilizer.

[0017] Furthermore, the columns are cement columns or galvanized steel pipe columns.

[0018] Furthermore, the combinations of the number of secondary side branches, tertiary side branches and fruiting mother branches include: 8 secondary side branches, 24 tertiary side branches, and 72 fruiting mother branches per layer; or 10 secondary side branches, 20 tertiary side branches, and 60 fruiting mother branches.

[0019] In summary, the present invention has the following beneficial effects compared with the prior art:

[0020] The tree shape obtained by the method for cultivating a kumquat hedge-type layered fruit-bearing tree shape provided by the present invention can greatly simplify the technical difficulty of pruning and realize the digital management of kumquat branches, tips and fruits. At the same time, the space occupied by the tree body is saved, which is convenient for mechanical management and improves labor efficiency. In addition, the fruit-bearing branches of the tree shape are evenly distributed on both sides, which is convenient for fruit picking, and the photosynthetic efficiency of the layered fruit-bearing method is uniform, the difference in fruit quality is small, and the fruit commodity rate is high.

[0021] The tree shape obtained by the cultivation method provided by the present invention has a crown height of about 2.2m, and a width of the fruit-hanging layer of the hedge wall of 0.8m-1.2m; there is no branch below the central trunk 70cm, and there are 2 branches every 40cm on average above 70cm, about 50cm long, evenly distributed on both sides of the central branch and fixed on the wire, so that it grows horizontally, and each side branch leaves 5 secondary side branches, each secondary side branch leaves 3 tertiary side branches, and 2 fruit-bearing mother branches are left on the tertiary side branches. This tree shape needs to be managed from the seedling, and it can be formed in 2 years, and a certain yield can be achieved in the third year. After artificial topping, bud touching or short cutting, the remaining fruit-bearing branches can be controlled, and the expected yield can be controlled. At the same time, due to the refined management of the branches in the early stage, the remaining branches of the whole tree can be quantified, and the pattern of the whole tree is finalized, which reduces the difficulty of promotion and is more conducive to standardized production. This tree shape greatly reduces the tree diameter, so that the tree shape changes from a round shape to a hedge wall shape, saves the space occupied by the tree body, is convenient for mechanical management, and improves labor efficiency. In addition, the fruiting branches of this tree shape are artificially fixed to grow in a direction perpendicular to the side branches. The fruiting branches do not cross, resulting in less mechanical damage and easy picking. The layered fruiting method has uniform photosynthetic efficiency, small differences in fruit quality, and a high commercial rate of fruit. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form can also include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0030] See also Figure 1 to Figure 2 As shown, the present invention provides a method for cultivating a golden mandarin orange hedge wall-type layered fruit-bearing tree, comprising the steps of:

[0031] S1: Seedling selection

[0032] Traditional kumquat seedlings, whether bare-root seedlings or container seedlings, generally require 1 main trunk and 3 branches. When cultivating fan-shaped layered fruit-bearing trees, a main trunk is required to grow upward, and no branches are required on the main trunk, so a single-stem seedling is sufficient. Therefore, the seedlings used only need to have a trunk diameter of more than 1 cm (strong seedlings) 10 cm above the grafting point and a height of more than 80 cm, that is to say, only 2-3 year-old container seedlings or seedlings with soil balls with a trunk diameter of more than 1 cm 10 cm above the grafting point (about 10 cm from the ground) are required. According to actual operating experience, 2-3 year-old container seedlings or seedlings with soil balls with a trunk diameter of more than 1 cm 10 cm above the grafting point are selected because seedlings at this stage are easier to survive during the tree cultivation (planting) process; and the tree shape of this year is still in the development stage, and after artificial intervention, the tree shape can be changed to what people need.

[0033] S2: Column Setting

[0034] Before planting, the column and four layers of iron wire are set, and a column is set every 5m in the vertical direction and every 2.5m in the horizontal direction. The column is 3.2m high and buried in the soil for 0.6m. Four layers of iron wire are pulled between each column. From bottom to top, the first layer of iron wire is 0.7m away from the ground, and then a layer of iron wire is set every 0.4m, and four layers are set in total. The column can not only be set with iron wire to prepare for branch binding, but also can be set with a rain shelter to shade and shelter kumquat when necessary. After setting, seedling planting can be carried out, and 5 seedlings are evenly planted between every two columns. In the actual operation process, the vertical spacing distance of the column, the horizontal spacing distance and the column height are determined according to multiple cultivation experiences. According to the vertical spacing distance of the present invention, the horizontal spacing distance of the column is every 5m, the horizontal spacing distance of the column is every 2.5m and the column height is 3.2m, and the best fruit tree shape described in the present invention can be cultivated. Similarly, the wire spacing of each layer is also the same. In addition, the buried depth of the column may not be limited to 0.6m as described in the present invention. When encountering relatively soft soil, the buried depth may be appropriately increased; when encountering relatively tight soil, the buried depth may be appropriately reduced. The buried depth value provided by the present invention is determined based on many years of fruit tree cultivation experience and is an average value.

[0035] As a preferred embodiment, the columns are cement columns or galvanized steel pipe columns. That is to say, if it is necessary to fix the columns in a certain place for a long time to cultivate the shape of fruit trees and there is plenty of time, cement columns with a long service life are selected. When a large number of fruit trees need to be cultivated in time due to production needs, prefabricated galvanized steel pipes are selected, and the columns can be quickly erected and the cultivation of fruit tree shapes can be started. Of course, galvanized steel pipes can also be used to cultivate the tree shape first, and the columns can be gradually replaced during the tree shape cultivation process.

[0036] S3: Planting of seedlings

[0037] After selecting the seedlings, the seedlings are planted, and the period is selected before the spring buds. Before planting, organic fertilizer is buried in the planting ditch in advance, and the plants are planted according to the spacing of 1m in the plant and 2.5m in the row. Planting can provide a larger space for the plant growth of plants, and is conducive to the better photosynthesis of the plant body. During the planting process, the spacing of the plant and the row are smaller, which is not conducive to the growth of the seedlings, and the spacing of the plant and the row are larger, which reduces the cultivation quantity of the seedlings. In the present invention, it is preferred that the spacing of the plant is 1m and the row is 2.5m for planting, and the influence between the adjacent seedlings is less at this time, and the nutrients provided by the soil in the adjacent area are also conducive to the growth of the seedlings. And when the seedlings grow up, it is also conducive to the staff to walk between the seedlings and implement further operations. Of course, if machinery is used to cultivate the seedlings, the row spacing can be changed according to actual needs.

[0038] After transplanting, when the top of the strong seedling is about 5 cm away from the first wire, prune it to promote branching. After pruning, erect a support pole. After it branches, tie the central trunk to the support pole to make it grow upright. When the two side branches grow to about 35 cm, pinch them to promote the germination of secondary side branches. When they are mature, pull the branches and tie them to the wires on both sides to make them grow horizontally. After setting up four layers in this way, pinch the branches to control the growth of the trees.

[0039] As a preferred embodiment, depending on the planting area and soil environment, the row spacing of 2.5 meters described in the present invention can be selected to be 3 meters or 3.5 meters according to the mechanized farming mode.

[0040] S4: Management during lateral growth

[0041] After pulling the branches, the side branches grow horizontally. When necessary, buds or medicine are applied to accelerate germination, leaving a secondary side branch about every 10 cm, evenly distributed on both sides of the side branches. When the secondary side branches have a certain length, pull the branches to make them grow vertically with the side branches, and leave 3 tertiary side branches evenly on the secondary side branches, and leave 2 fruiting branches on the tertiary side branches. When the length of the side branches reaches about 50 cm, pinch the tops to control their growth. In other words, removing the broken branches, diseased branches and excess fruit branches can concentrate the nutrients of the fruit trees on some fruit branches to ensure the quality of the fruit. The number of side branches to be removed provided by the present invention is summarized based on actual experience, and the pruning of side branches of different grades can be implemented according to the method provided by the present invention, which can ensure the quality and quantity of the fruits of the fruit trees.

[0042] As a preferred method, according to the actual situation of the fruit branches, the number of secondary side branches, tertiary side branches and fruiting mother branches can be diversified, such as 8 secondary side branches, 24 tertiary side branches, and 72 fruiting mother branches per layer. Or 10 secondary side branches, 20 tertiary side branches, 60 fruiting mother branches, etc. S5: In the early spring of the second year, uniform pruning, bud fertilizer, and tertiary side branches are cut short to promote their branching, leaving two branches that promote branching, and the rest of the branches are cut off in time.

[0043] S6: At the end of the third year, the cultivation of hedge-style layered fruit-bearing tree shape is completed, the tree height is controlled at about 2m, the width of the hedge-style fruit-bearing layer is 0.8m to 1.2m, there are 2 side branches every 40cm on the central trunk on average, 5 secondary side branches are evenly distributed on the side branches, 3 tertiary side branches are left on the secondary side branches, and two fruiting mother branches are left on the tertiary side branches. The branches are distributed in a hedge-style.

[0044] Kumquat is different from other citrus varieties in that its main fruiting branches are the spring shoots that grow in the current year. In winter, it can be pruned short so that the remaining fruiting branches can be controlled, achieving the expected controllable yield. This tree shape greatly simplifies the technical difficulty of pruning and realizes the digital management of kumquat branches, shoots, and fruits. At the same time, it saves the space occupied by the tree, facilitates mechanical management, and improves labor efficiency. In addition, the fruiting branches of this tree shape are evenly distributed on both sides, which is convenient for fruit picking. The layered fruiting method has uniform photosynthetic efficiency, small differences in fruit quality, and a high fruit commercial rate.

[0045] The method for cultivating kumquat hedge-wall-type layered fruit-bearing tree shape provided by the present invention can roughly evaluate the number of fruits, and the accuracy of the number of fruits reaches more than 90%; therefore, the estimation of the number of fruits produced in the orchard and the estimation and control of the area occupied by the fruit trees can be achieved through the digital management method. The method for digital management of kumquat is as follows:

[0046] (1) Side branches and secondary side branches

[0047] like Figure 3 As shown, each kumquat tree has four layers of side branches, each layer has two side branches on the left and right, and the whole tree has a total of 8 side branches. Each side branch has 5 secondary side branches evenly growing on both sides of the side branch, and the whole tree has a total of 40 secondary side branches. When the secondary side branches have a suitable length, pull the branches to make them grow vertically with the side branches.

[0048] (2) Third-level side branches

[0049] like Figure 4 As shown, when new shoots grow on the secondary side branches, 3 tertiary side branches are left on the secondary side branches, growing evenly on the secondary side branches, and the whole tree has a total of 120 tertiary side branches.

[0050] (3) Fruiting mother branch

[0051] like Figure 5 As shown, when new shoots grow on the tertiary side branches, leave 2 fruiting mother branches on the tertiary side branches and grow evenly on the tertiary side branches. The whole tree has a total of 240 fruiting mother branches, and each fruiting mother branch can have 1.5 fruits, so the whole tree can produce 360 ​​fruits, that is, the expected yield can be obtained, and digital management of the yield can be realized.

[0052] (4) Summary

[0053] The kumquat hedge-wall-style layered fruit-bearing tree has two side branches when it is 0.7m above the ground, which is one layer. Then the next layer is separated every 0.4m, for a total of 4 layers. When each side branch has a suitable length, tie the branch to make it grow horizontally. When it is about 0.5m long, pinch it to control its growth. Use bud carving or germination to control the position of the secondary side branches that sprout on it to make it uniform. The number of secondary side branches on each side branch is controlled to be 5. When the secondary side branches have a certain length, pull the branches to make them grow vertically with the side branches, that is, "extend outward". When new shoots grow on the secondary side branches, leave 3 tertiary side branches on the secondary side branches, and grow evenly on the secondary side branches. When new shoots grow on the tertiary side branches, leave two fruiting mother branches. Therefore, the number of side branches left at each step is very clear, and its expected yield can be calculated, which is an important part of realizing digital management.

[0054] As a preferred option, kumquat is prone to flowering when exposed to high temperature and drought, which is not conducive to the growth of branches and shoots. Young trees can be sprayed with 25mg / L GA3 when the branches and shoots are 80% mature in the high temperature season of summer and autumn, and high-nitrogen fertilizer can be applied to promote branch sprouting and reduce flowering.

[0055] The following is a series of data obtained by actually using the method for cultivating the golden orange hedge wall-type layered fruit-bearing tree shape provided by the present invention:

[0056] At the kumquat demonstration base in Tanxia Town, Lingchuan County, Guilin City, Guangxi Province, the average fence thickness of the fence-type fan-shaped layered tree transformed according to the method of the present invention in 2023 was 126.0±5.0cm, and the shoots of each layer were basically consistent. In 2024, three layers of fruits were formed, basically forming a fence-type fan-shaped layered tree.

[0057] Compared with the traditional natural round-head tree shape, the hedge-wall fan-shaped layered tree shape of the present invention is convenient to manage, greatly simplifies the pruning process, and improves labor efficiency; it increases the commercial fruit rate, reduces fruit supporting work, and can ensure that the liquid of mechanical pesticides can enter the interior of the tree crown, thereby improving the prevention and control effect of diseases and pests.

[0058] At the same planting location and the same water and fertilizer management mode, the light intensity and fruit quality of the conventional natural round-headed Crisp Honey Kumquat and the hedge-wall-type layered fruit-hanging tree shape of the present invention were measured.

[0059] Under the same planting conditions, the light intensity of the 1st, 2nd and 3rd layers of the hedge-type layered fruit-bearing tree shape of the present invention was measured, which were 117.22±8.22 (*1000lux), 118.32±12.32 (*1000lux), 124.24±5.46 (*1000lux) and 124.26±4.76 (*1000lux), respectively, and the light intensity of each layer was not much different; while for the natural round head shape, it was measured that the external light intensity was 118.76±4.54 (*1000lux), and the internal light intensity was 67.16±27.66 (*1000lux), which was only 56% of the external light intensity, and the difference was large, reflecting the high light efficiency of the tree shape of the present invention.

[0060] The fruit quality of the first, second and third layers of the hedge-wall layered fruit-bearing tree of the present invention was analyzed, and the data showed that the soluble solids of the fruits of the first, second and third layers were 17.9±1.7(%), 18.35±1.35(%) and 18.75±0.95(%), respectively, and the titratable acid was , respectively, which was not much different. The soluble solids of the middle upper part and the middle lower part of the conventional natural round head shape were 18.4±0.3(%) and 16.8±1.8(%), respectively, and the titratable acid content was , which was quite different, indicating that the fruit quality consistency and commercial rate of the present tree shape were high.

[0061] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
