Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plant trellis cultivation, in particular to a fruit tree trellis cultivation method. BACKGROUND

[0002] Trellis cultivation is a modern cultivation mode that guides plant growth by setting up a support system, especially suitable for fruit tree management. This technology optimizes light distribution, ventilation conditions and space utilization by fixing branches at a specific angle on the shelf surface, thereby significantly improving fruit quality and yield.

[0003] Among them, traditional planting modes such as 2D single-plane tree shape have been widely used, but the plant spacing is larger, resulting in lower planting density per unit area and limited land utilization. Various high-density cultivation modes have been explored at home and abroad, such as V-shaped shelves, Y-shaped shelves, etc., but these modes still have problems such as complex tree shape control and insufficient mechanical adaptability. SUMMARY

[0004] One of the purposes of the present application is to provide a fruit tree trellis cultivation method that is convenient for mechanized operation, simple to manage, and suitable for modern high-density labor-saving cultivation technology requirements.

[0005] The technical solution of the present application is as follows:

[0007] S100: erecting double-row V-shaped trellis;

[0008] S200: setting steel wire mesh on the V-shaped trellis;

[0009] S300: planting double-row seedlings, and horizontally binding the first-order lateral branches of each seedling to the steel wire mesh to form a fruit wall for each row of seedlings;

[0010] S400: shaping in the first year;

[0011] S500: shaping in the second year;

[0012] S600: shaping in the third year;

[0013] S700: shaping in the fourth year;

[0014] S800: completing trellis cultivation in the fifth year.

[0015] Further, step S100 comprises:

[0016] S110: burying two cement columns opposite to each other at the head of the row, adjusting the angle to form a V-shaped trellis;

[0017] S120: Use ground anchors and balance rods to fix the water column, and then add anti-sinking plates;

[0018] S130: Lay the V-shaped grids evenly along the row with a spacing of 8.4m, and build a set of fixed structures at the end of the row.

[0019] Furthermore, step S200 includes:

[0020] S210: Pull 18 steel wires at the same level along the concrete columns on the same side of each V-shaped grid, with 9 wires in each row. Each steel wire is fixed to the V-shaped grid with a clamp.

[0021] The distance between the first steel wire and the ridge surface is 50 cm, and the distance between each steel wire above is 33 cm. Each steel wire is tightened with a tensioner to form two steel wire mesh surfaces on both sides of the V-shaped grid;

[0022] S220: After the wire mesh is constructed, vertically tie a bamboo pole every 1.2m on the same side of the wire mesh. Each bamboo pole is fixed to each steel wire with a clamp.

[0023] Step S300 includes:

[0024] When planting seedlings, the trunk must be parallel to the bamboo pole and tied to the bamboo pole. The seedling height must be above 1.5 meters and the number of branches greater than 30 centimeters in length must be greater than or equal to 4.

[0025] Furthermore, step S400 includes:

[0026] S410: Planting and pruning: After the seedlings are planted, branches damaged during transportation, diseased and insect-infested branches are pruned, and the stumps are left at 2 cm.

[0027] S420: First-level side branch binding: After the seedlings have grown, select the first-level side branches near the wire mesh surface for binding. Select the left and right first-level side branches on the main trunk, 5 cm above and below the wire, and growing horizontally along the wire.

[0028] S430: Pruning of extra first-level side branches on the main trunk: After tying the first-level side branches, cut off the extra side branches on the main trunk from the base;

[0029] S440: Main trunk bud removal: When new buds grow to about 10 cm in spring, remove all side buds on the main trunk that do not need to be tied;

[0030] S450: Main trunk selection and binding: After the long branches stop growing in summer, the main trunk is selected and bound;

[0031] From the end of July to the beginning of August, when the central leader grows to more than 30cm, first select the top of the main trunk extension, that is, cut off the thin and weak first-level side branches within 30cm of the main trunk, leaving a strong and best-growing branch as the central leader;

[0032] After selecting the main trunk tip, use a branch tying machine to tie the main trunk to the bamboo pole.

[0033] Furthermore, step S500 includes:

[0034] S510: Cultivate side branches: Before spring bud break, for those side branches not tied to the steel wire on the main trunk, cut all the buds 5 cm above and below the steel wire or apply a branching agent to promote branching;

[0035] From the end of May to the beginning of June, tie up the first-level side branches that are not tied near the wire and have grown to 30 cm;

[0036] Pinch off the newly grown buds on the tied side branches that are 10-15 cm long to promote flowering;

[0037] S520: Trunk processing: Refer to step S450 to perform trunk head selection and binding;

[0038] S530: Pruning: Perform pre-flowering pruning and summer pruning;

[0039] Pruning before flowering: Prune the fruiting branches on the tied primary side branches that are longer than 30 cm and cut them back to within 30 cm. If there are flower buds, leave 3 flower buds for cutting back. If there are no flower buds, leave 3 visible buds for cutting back.

[0040] Summer pruning: Summer pruning begins when the summer solstice arrives. During summer pruning, the back branches on the tied first-level side branches will be cut short to 8 leaves on fruit-bearing branches and 3 leaves on fruitless branches, and the rest will be pruned.

[0041] Furthermore, the step S600 includes:

[0042] S610: Side branch processing: For main branches with insufficient side branches, refer to step S500 to perform the stimulating branch and primary side branch binding operation;

[0043] For the tied primary side branches, refer to step S500 to perform topping, summer pruning, and pre-flowering pruning operations to promote the growth of short branches;

[0044] S620: Main branch processing: refer to step S450 to perform head selection and binding operations.

[0045] Furthermore, the step S700 includes:

[0046] S710: Side branch processing: For the main trunk position with less than 18 bound side branches, refer to step S500 to perform the triggering branch and primary side branch binding operation;

[0047] For seedlings that have already met the requirements of 18 side branches, it is only necessary to refer to the pruning operation in step S530 to maintain small short branches for fruiting.

[0048] S720: trunk processing: if the trunk has reached 3m, bend the trunk and bind it to the 9th steel wire, so that it acts as a first-order branch;

[0049] If the trunk has not reached 3m, continue to refer to step S450 for selection and binding.

[0050] Further, in step S110, the angle between the two cement columns constituting the V-shaped frame is 24°.

[0051] Further, in step S300, the fruit trees planted are apple trees, which have been cultivated for 5 years, with a tree height of 3.2m, 18 first-order branches, and 7-10 fruiting short branches on each first-order branch, forming a fruiting branch group.

[0052] And the fruiting branch group grows in a fishbone shape on the first-order branch, with each fruiting short branch being less than 30cm long.

[0053] Further, the operation of S510 is as follows: at 0.5-1.0cm above the bud, use a single-edged blade or bud carving knife to make 1 / 2-2 / 3 turns around the trunk and carve to the xylem; the bud carving time must be completed before the bud sprouts.

[0054] The operation of applying the fruiting element is as follows: dip a cotton swab in the fruiting element and apply it to the bud tip.

[0055] The beneficial effects of the present application are:

[0056] 1. Significant synergistic effect, greatly improving yield:

[0057] High-density planting: the plant spacing can be reduced to 0.6cm, and the planting density is increased to 317 plants per mu, greatly utilizing the planting space (spindle-shaped plant spacing 1.2m, 159 plants per mu).

[0058] High yield and stable yield: the yield per mu during the high-yield period can reach 9 tons, which is 1.5-1.8 times that of conventional high-spindle tree shape. The single-branch fruiting ability is strong, the fruiting sites are evenly distributed, the size year phenomenon is not obvious, and sustained high yield and stable yield are achieved.

[0059] 2. Improve fruit quality and commodity rate:

[0060] Optimize the light environment: the 2D+V double-plane structure and the frame design significantly improve the light interception rate, which is more than 50% higher than that of traditional tree shapes such as high spindle tree shape, and the light can pass through the center of the tree canopy, promoting uniform fruit ripening.

[0061] Increase the rate of goods: the fruit in the wire mesh surface in line, full, uniform illumination, significantly improve the internal quality of fruit (such as sugar content, color) and appearance consistency. The plane structure greatly facilitates the bagging, picking and other fine operation, reduces the fruit damage, directly improves the rate of commodity fruit.

[0062] 3, improve land utilization: through the plant spacing is reduced to 0.6 cm and the unique double plane upward growth structure, more fruit trees (317 plants per mu) are accommodated in unit land area, the space utilization is maximized, the land resource utilization efficiency is significantly improved, and the unit area yield is maximized.

[0063] 4, reduce labor management cost:

[0064] Easy to operate: the tree structure is simplified, and the whole tree has only 18 first order lateral branches. The double plane structure is suitable for mechanized picking, pruning and other operations, and the operation efficiency is greatly improved.

[0065] Pruning simplification: only the small fruiting branch group on the first order lateral branch needs to be pruned, the operation is simple and labor-saving, the tree height is controlled reasonably, the manual operation is facilitated, and the labor cost is reduced.

[0066] Reducing fertilizer input: pruning the overgrown branches, diseased branches and the like in summer, effectively reducing the nitrogen consumption of the tree body, so that the nutrients are concentrated to supply flowers and fruits, and the nutrient input is indirectly reduced.

[0067] 5, easy to standardize, promote industrial upgrading: the geometric configuration of double plane + grid is simple and regular, and the tree shape standardization is easy to realize. The tree structure is simple (first order lateral branch + fruiting branch group), which is suitable for mechanical operation, so that the whole set of cultivation technology is simple and easy to learn, and is easy to standardize, which lays a solid foundation for realizing the modern orchard management of standardization, mechanization and intensification. BRIEF DESCRIPTION OF DRAWINGS

[0068] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0070] Figure 2 It is a schematic diagram of binding after the seedling survival. DETAILED DESCRIPTION

[0071] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are involved in the protection scope of the present application.

[0072] As Figure 1-2 As shown, the present application provides a fruit tree trellis cultivation method, mainly applied to, but not limited to, apple tree cultivation, through V-shaped trellis structure design, precise shape control of steel wire mesh surface, four-year systematic shaping and supporting dynamic management, realizing efficient light energy utilization, early fruiting, yield, quality improvement and mechanization adaptation of apple trees, especially suitable for large-scale dwarfing and dense planting orchard application. Specifically, the steps include:

[0073] S100: erecting double-row V-shaped trellis;

[0074] Step S100 includes:

[0075] S110: burying two cement columns opposite to each other at the head of the row, adjusting the angle to form a V-shaped trellis;

[0076] S120: fixing the water column with ground anchors and balance bars, and then adding a sinking prevention plate;

[0077] S130: evenly laying each V-shaped trellis along the row with a spacing of 8.4m, and building a set of fixed structure at the end of the row.

[0078] It should be noted here that the V-shaped trellis at the head and end of the row needs to be installed with a sinking prevention plate, so the steel wire mesh surface needs to be inspected and adjusted to maintain the same spacing between each steel wire as when installed. The reinforcement design at the head and end of the row combined with regular inspection prevents the V-shaped trellis from deforming due to load (fruit weight) or soil settlement, prolonging the service life of the facility.

[0079] The design of V-shaped double-row trellis can form two inclined result walls, allowing the tree canopy to be layered and lighted, reducing mutual shading of branches and leaves, increasing light receiving area and improving photosynthetic efficiency.

[0080] S200: setting up a steel wire mesh surface on the V-shaped trellis;

[0081] Step S200 includes:

[0082] S210: along the same side of the cement column of each V-shaped trellis, 18 steel wires are pulled at the same horizontal height, 9 wires per row, and each steel wire is fixed to the V-shaped trellis by a clamping piece;

[0083] The distance between the first steel wire and the ridge is 50cm, and the distance between each steel wire is 33cm, and each steel wire is tightened with a wire tightener, forming two steel wire mesh surfaces on both sides of the V-shaped trellis;

[0084] S220: After the construction of the steel wire mesh surface, a bamboo pole is vertically bound every 1.2m on the same side of the steel wire mesh surface, and each bamboo pole is fixed to each steel wire by a clamping piece.

[0085] The layered distribution of 18 steel wires can precisely control the spatial positioning of branches. Combined with the vertical support of bamboo poles, it can achieve a three-dimensional fruiting surface, maintain the balance between the tree's nutritional growth and reproductive growth, and increase the yield per unit area.

[0086] S300: Planting double rows of seedlings, horizontally tying the primary side branches of each seedling to the wire mesh surface, so that each row of seedlings forms a fruiting wall;

[0087] When planting the seedlings, the trunk must be parallel to the bamboo pole and tied to the bamboo pole. The seedling height must be above 1.5 meters and the number of branches greater than 30 centimeters in length must be greater than or equal to 4.

[0088] S400: Plastic surgery in the first year;

[0089] Step S400 includes:

[0090] S410: Planting and pruning: After the seedlings are planted, branches damaged during transportation, diseased and insect-infested branches are pruned, and the stumps are left at 2 cm.

[0091] S420: First-level side branch binding: After the seedlings have grown, select the first-level side branches near the wire mesh surface for binding. Select the left and right first-level side branches on the main trunk, 5 cm above and below the wire, and growing horizontally along the wire.

[0092] S430: Pruning of extra first-level side branches on the main trunk: After tying the first-level side branches, cut off the extra side branches on the main trunk from the base;

[0093] S440: Main trunk bud removal: When new buds grow to about 10 cm in spring, remove all side buds on the main trunk that do not need to be tied;

[0094] S450: Main trunk selection and binding: After the long branches stop growing in summer, the main trunk is selected and bound;

[0095] From the end of July to the beginning of August, when the central leader grows to more than 30cm, first select the top of the main trunk extension, that is, cut off the thin and weak first-level side branches within 30cm of the main trunk, leaving a strong and best-growing branch as the central leader;

[0096] After selecting the main trunk tip, use a branch tying machine to tie the main trunk to the bamboo pole.

[0097] S500: Plastic surgery in the second year;

[0098] Step S500 includes:

[0099] S510: Cultivate side branches: Before spring bud break, for side branches not tied to the main stem wire, cut all buds 5 cm above and below the wire, or apply a branching agent to the empty parts of the primary side branches to promote branching;

[0100] From the end of May to the beginning of June, tie up the first-level side branches that are not tied near the wire and have grown to 30 cm;

[0101] Pinch off the newly grown buds on the tied side branches that are 10-15 cm long to promote flowering;

[0102] The above-mentioned bud carving operation is as follows: Use a single-sided blade or a bud carving knife to circle the trunk 1 / 2 to 2 / 3 of the way 0.5 to 1.0 cm above the bud, and carve into the wood. The bud carving time must be completed before the bud germinates.

[0103] The operation of applying the hair-branching agent is as follows: dip a cotton swab in the hair-branching agent and apply it to the tip of the bud. Commonly used hair-branching agents are thiadiazole and 6ba (6-benzylaminopurine).

[0104] Operations such as carving buds in empty areas / using branching agents to promote branching, extending side branches to fill in the gaps, and using upper branch groups to make up for the deficiencies in the lower layers ensure that there are no gaps in the fruiting wall and maintain long-term stable production.

[0105] S520: Trunk processing: Refer to step S450 to perform trunk head selection and binding;

[0106] S530: Pruning: Perform pre-flowering pruning and summer pruning;

[0107] Pruning before flowering: Prune the fruiting branches on the tied primary side branches that are longer than 30 cm and cut them back to within 30 cm. If there are flower buds, leave 3 flower buds for cutting back. If there are no flower buds, leave 3 visible buds for cutting back.

[0108] Summer pruning: Summer pruning begins when the summer solstice arrives. During summer pruning, the back branches on the tied first-level side branches will be cut short to 8 leaves on fruit-bearing branches and 3 leaves on fruitless branches, and the rest will be pruned.

[0109] Summer pruning combined with growth regulators can force short branches to bloom and avoid excessive growth, thus achieving early fruiting under dwarfing and dense planting (forming in 3 years and high yield in 4 years).

[0110] S600: Plastic surgery in the third year;

[0111] Step S600 includes:

[0112] S610: Side branch processing: For main branches with insufficient side branches, refer to step S500 to perform the stimulating branch and primary side branch binding operation;

[0113] For the tied primary side branches, refer to step S500 to perform topping, summer pruning, and pre-flowering pruning operations to promote the growth of short branches;

[0114] S620: Main branch processing: refer to step S450 to perform head selection and binding operations.

[0115] S700: Pruning in the fourth year;

[0116] Step S700 includes:

[0117] S710: Side branch treatment: for the trunk part with less than 18 bound side branches, the branch inducing and first level side branch binding operation is performed according to step S500;

[0118] For the seedling with 18 side branches, only the pruning operation according to step S530 is needed to maintain the short fruiting branches.

[0119] S720: Trunk treatment: if the trunk has reached 3 m, the trunk is bent and bound to the 9th steel wire to serve as a first level bound side branch;

[0120] If the trunk has not reached 3 m, the selection and binding according to step S450 are continued. The bending of the trunk or the breaking of the trunk by wind can be avoided, and the overall wind resistance is enhanced, especially when the 3 m high trunk is bent and bound to the 9th steel wire.

[0121] S800: Complete the trellis cultivation in the fifth year.

[0122] In step S110, the included angle between the two cement columns constituting the V-shaped trellis is 24°.

[0123] In step S300, the fruit trees selected for planting are apple trees. After 5 years of cultivation, the apple trees have a height of 3.2 m, 18 first level side branches, and 7-10 fruiting short branches on each first level side branch, forming a fruiting branch group.

[0124] The fruiting branch group on the first level side branch has a fishbone shape or bifurcated structure, which refers to the structure formed by the radial arrangement of the fruiting branch group on the first level side branch, and the arrangement growth is performed, with each fruiting short branch having a length of less than 30 cm.

[0125] The embodiment also uses the following supporting technologies:

[0126] 1. When binding the first level side branches near the steel wire, try to select two branches above and below the steel wire, and the branches grow horizontally along the steel wire.

[0127] 2. When cultivating the fruiting branch group on the first level side branch, try to select the lateral buds to make the fruiting short branches on the first level side branch grow alternately and form a fishbone arrangement.

[0128] The fruit is evenly distributed, the ventilation and light transmission are reduced, and the color and sugar degrees are improved.

[0129] 3. When the appropriate first level side branches cannot be selected for binding near the steel wire, the adjacent side branches can be extended to fill the empty space.

[0130] 4. When there are too few fruiting branches on the lower-level side branches, the length of the upper-level fruiting branches can be slightly extended to make up for the lack of space in the lower-level fruiting branches.

[0131] 5. In order to maintain the length of the fruiting branches on the primary side branches within 30 cm, in addition to pruning, it is also necessary to spray plant growth regulators to stop their growth at the appropriate time.

[0132] This embodiment rapidly cultivates a fishbone-shaped fruiting system with 18 primary branches through annual binding, bud carving, pinching, pruning, and hormone regulation, shortening the traditional apple tree formation cycle. Combining growth hormones with pruning regulates the balance between vegetative and reproductive growth, reducing the frequency of manual pruning. The double-row V-shaped fruiting wall facilitates mechanized operations (spraying and harvesting), which can be efficiently carried out through the V-shaped channel, reducing labor intensity.

[0133] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
