Description

Technical Field

[0001] The invention relates to the technical field of grape planting, in particular to a wine grape planting method. Background Art

[0002] Wine grapes are grapes used for winemaking. As a highly technology-intensive agricultural activity, the success of wine grape cultivation depends not only on the selection and cultivation of grape varieties, but also on the unique geographical environment and climatic conditions of the planting area. Globally, different regions provide incomparable environmental conditions for the growth of wine grapes due to their unique natural advantages, which may include suitable climate, fertile soil, sufficient sunshine and just the right amount of precipitation.

[0003] However, despite these natural advantages that bring unlimited possibilities to wine grape cultivation, traditional wine grape cultivation techniques often face a series of challenges. The slow formation of the trellis is one of the key factors restricting the efficiency of traditional wine grape cultivation. The trellis, that is, the supporting structure and growth form of the wine grape plant, has an important impact on the yield and quality of wine grapes. However, under traditional cultivation techniques, wine grape plants often take a long time to form an ideal trellis, which not only affects the lighting and ventilation conditions of wine grapes, but also limits the improvement of wine grape yield and quality.

[0004] In addition, the problem of taking the grapes off the shelves and burying them in the soil in winter to protect them from the cold is also an issue that cannot be ignored in traditional wine grape cultivation. In cold regions, in order to prevent the wine grape plants from freezing in winter, growers usually need to take the grapes off the shelves and bury them in the soil in autumn, which not only increases labor costs, but may also damage the root system of the wine grapes, thereby affecting the growth and yield of the next year. At the same time, frequent operations of taking the grapes off the shelves and putting them on the shelves also increase the risk of the wine grape plants being infected with pests and diseases, which is not conducive to improving the yield and quality of wine grapes. Summary of the invention

[0005] In view of this, the present invention aims to provide a wine grape planting method to help improve the yield and quality of wine grapes.

[0016] Furthermore, the fourth preset height ranges from 0.33m to 0.37m; and / or, when the vines are tied up, the vines are tied up in a T-shape using iron wire.

[0017] Furthermore, the membrane structure is covered on both sides of the seedlings so that the soil on both sides of the seedlings is covered under the membrane structure, including: leveling the land on both sides of the main vine after the vines are branched and buds are removed and the shoots of the main vine are cleared; laying the membrane structure along the roots of the main vine to both sides of the main vine; fixing the edges of the membrane structure to complete the covering of the membrane structure.

[0018] Furthermore, the depth of the grooves on both sides of the main vine is in the range of 0.10m-0.15m; and / or the width of the grooves on both sides of the main vine is in the range of 0.20m-0.40m.

[0019] Furthermore, the membrane structure is a layered structure woven from waterproof material, and the membrane structure has micropores for water to flow to the ground.

[0020] Furthermore, drainage holes are evenly arranged on the membrane structure located at the bottom of the groove.

[0021] Further, the first preset row spacing is in the range of 2.5m-3m; and / or, the first preset plant spacing is in the range of 0.68m-0.72m; and / or, the first preset height is in the range of 0.38m-0.42m; and / or, the second preset height is in the range of 0.45m-0.50m; and / or, the first preset length is in the range of 0.30m-0.35m; and / or, the second preset length is in the range of 0.1m-0.15m; and / or, the third preset height is in the range of 1m-1.2m.

[0022] Furthermore, the method also includes: when the height of the sprout grows to a fifth preset height, tying the second posture; when the height of the sprout grows to a sixth preset height, tying the third posture.

[0026] In addition, by pinching the main vine tip, it is beneficial to ensure the nutrient distribution during the growth of the seedlings, which is conducive to the fruiting of wine grapes. The branch vines are tied to a T-shaped frame with iron wire, which is convenient for the processing and operation of the frame, and is conducive to the implementation of the design. After removing the buds from the branch vines and the sprouts of the main vine, the land is leveled and the membrane structure is laid, which is conducive to ensuring the soil moisture when the sprouts on the branch vines grow and preventing the growth of weeds, which is conducive to the implementation of the design. By controlling the depth and width of the grooves on both sides of the main vine, it is helpful to drain water to the ground and help the growth of the main vine, which is conducive to the implementation of the design.

[0036] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0037] Embodiment 1

[0038] This embodiment relates to a wine grape planting method, which aims to improve the yield and quality of wine grapes by optimizing the wine grape planting steps.

[0039] The wine grape planting method in this embodiment is carried out step by step from the planting of wine grape seedlings to the production of wine grapes. Before the detailed introduction of the wine grape planting method in this embodiment, it is necessary to briefly introduce the related concepts involved. Wine grapes are grapes used for winemaking, which are different from ordinary edible grapes, so the emphasis in the planting process is different. The main vine is the main branch of the wine grape seedling located above the ground. Usually there is only one main vine. The branch vine is the side branch that grows from the sprouts growing outward from the main vine. Usually the number of branch vines needs to be determined according to the planting needs. The sprouts are other sprouts that grow again during the growth process after the main vine is pinched.

[0040] In terms of overall conception, Figure 1 As shown, the wine grape planting method in this embodiment comprises the following steps:

[0041] Step S1, planting wine grape seedlings according to a first preset row spacing and a first preset plant spacing.

[0042] Among them, in this step S1, before planting the wine grape seedlings, first dig pits according to the first preset row spacing and the first preset plant spacing, place the seedlings in the pits accordingly, and bury the roots of the seedlings under the ground, wherein the row spacing is the distance between adjacent rows of seedlings, and the plant spacing is the distance between adjacent seedlings in each row of seedlings. In this embodiment, the range of the first preset row spacing is 2.5m-3m, and the range of the first preset plant spacing is 0.68m-0.72m. In this embodiment, preferably, the first preset row spacing is 2.5m, and the first preset plant spacing is 0.7m. By planting the wine grape seedlings at fixed row spacing and plant spacing, it is beneficial to ensure that each seedling can obtain sufficient sunlight, which is beneficial to the growth of wine grapes.

[0043] Step S2: After the main vine of the seedling grows to a first preset height, the main vine is pinched to the tip, and two branch vines are retained and tied to form a T-shape.

[0044] Among them, in this step S2, when pinching the tip of the main vine, it is also necessary to control the height of the main vine according to the fourth preset height, and retain the two branch vines growing on the side of the main vine. When tying the branch vines, the branch vines are tied in a T-shaped posture with iron wire. In this embodiment, the first preset height ranges from 0.38m to 0.42m, and the fourth preset height ranges from 0.33m to 0.37m. Preferably, the first preset height is 0.4m, and the fourth preset height is 0.35m. By pinching the tip of the main vine, it is beneficial to ensure the nutrient distribution during the growth of the seedlings, which is helpful for the fruiting of wine grapes. Tying the branch vines in a T-shaped posture with iron wire is convenient for the processing and operation of the posture, which is conducive to the design implementation.

[0045] Step S3: In the winter of the first year of the growth of the seedlings, the length of the branch vines is trimmed to a first preset length, and cold-proof soil is buried at a second preset height.

[0046] Among them, in this step S3, the length of the branch vines is trimmed to facilitate subsequent growth. When pruning, the distribution of buds on the branches can be used to ensure that the branch vines of two adjacent grape trees are reasonably distributed on the frame surface. At the same time, in this step S3, when burying the anti-freeze soil, the branch vines are kept on the frame, and the frame is buried in the anti-freeze soil. In this embodiment, the first preset length ranges from 0.30m to 0.35m, and the second preset height ranges from 0.45m to 0.50m. Preferably, the first preset length is 0.3m, and the second preset height is 0.45m. After the seedlings are put on the frame and tied up, they are directly buried in the soil in winter for cold protection, which is beneficial to reduce the number of times the seedlings are put on and taken off the frame, and is beneficial to ensure the growth of the seedlings.

[0047] Step S4: In the spring of the second year of the growth of the seedlings, the branch vines are unearthed and grooves are formed on both sides of the main vines.

[0048] Among them, in this step S4, in the spring of the second year, when the branch vines are unearthed, a mechanical unearthing method is adopted to remove the cold-proof soil covering the seedlings until the branch vines and part of the main vines of the seedlings are exposed to the ground, and grooves are formed on both sides of the seedlings at the same time. The grooves on both sides sandwich the main vine in the middle to form a W-shaped groove, and the main vine is located in the middle raised part of the W-shaped groove. In this embodiment, the depth of the grooves on both sides of the main vine ranges from 0.10m to 0.15m, and the width of the grooves on both sides of the main vine ranges from 0.20m to 0.40m. Preferably, the depth of the grooves on both sides of the main vine is 0.15m, and the width of the grooves on both sides of the main vine is 0.4m. The setting of the grooves is convenient for drainage in the rainy season, and making the main vine located in the middle raised part helps to keep the roots of the main vine warm. By controlling the depth and width of the grooves on both sides of the main vine, it helps to drain water to the ground and helps the growth of the main vine, which is conducive to design implementation.

[0049] Step S5, covering the ground on both sides of the main vine with a membrane structure, so that the soil on both sides of the main vine is covered under the membrane structure.

[0050] Among them, in this step S5, the membrane structure is covered on both sides of the main vine, and the soil cover on both sides of the main vine can be set under the membrane structure to prevent water from directly contacting the ground. In the rainy season, it helps to prevent rainwater from directly impacting the ground and splashing back mud to pollute the fruit surface. At the same time, the membrane structure can use dark materials, which can retain a certain amount of heat after direct exposure to the sun, which is beneficial to increase the heat of the roots of seedlings at night and is beneficial to the growth of seedlings. The membrane structure is covered on the ground, which is beneficial to the growth of buds on the branch vines, ensuring soil moisture and preventing weed growth, which is helpful for design implementation. Specifically, in this embodiment, this step S5 also includes the following steps

[0051] Step S51, after dividing the vines and removing the buds and suckers of the main vines, level the land on both sides of the main vines.

[0052] Among them, in this step S51, after the land on both sides of the main vine is leveled, it is helpful to lay the membrane structure so that the membrane structure fits the ground better.

[0053] Step S52: laying a membrane structure along the root of the main vine to both sides of the main vine.

[0054] Among them, in this step S52, laying the membrane structure along the root of the main vine to both sides of the main vine helps to ensure that the membrane structure is provided on both sides of each main vine.

[0055] Step S53: fix the edge of the membrane structure to complete the covering of the membrane structure.

[0056] Among them, in this step S53, when fixing the edge of the membrane structure, the membrane structure can be first fixed to the ground by ground nails, and a layer of soil is laid on the edge of the membrane structure to bury the edge of the membrane structure in the ground to prevent the membrane structure from being lifted.

[0057] In the steps S51-S53, after removing the buds from the branch vines and clearing the suckers of the main vines, the land is leveled and a membrane structure is laid, which helps to ensure soil moisture when the buds on the branch vines grow, prevents the growth of weeds, and facilitates the implementation of the design.

[0058] It is worth mentioning that in step S5, the membrane structure in this embodiment is a layered structure woven from waterproof material, and the membrane structure has micropores for water to flow to the ground. The waterproof material is woven so that the membrane structure in this embodiment has micropores, and rainwater can flow to the ground through the micropores of the woven structure. For better drainage effect, drainage holes are evenly arranged on the membrane structure at the bottom of the groove to assist in the rapid drainage of the bottom of the groove where water is easily accumulated. Making the membrane structure a woven layered structure helps to keep the ground breathable and prevent sunlight from directly hitting the ground, which is beneficial to ensuring the moisture of the soil. At the same time, it can assist drainage and avoid water accumulation on the membrane structure, which is beneficial to design implementation. Through the setting of the drainage holes, the drainage at the bottom of the groove is better guaranteed, and water accumulation due to the lower terrain at the bottom of the groove is prevented, which is helpful for design implementation.

[0059] Step S6: In the spring of the second year of the growth of the seedlings, the length of the sprouts on the vines is controlled according to the second preset length, and the height of the leaf curtain of the seedlings is controlled according to the third preset height.

[0060] Among them, in this step S6, by controlling the length of the sprouts on the vines, it is helpful to control the appropriate amount of fruiting, which is helpful for the growth of seedlings and avoiding excess nutrition. Controlling the height of the leaf curtain of the seedlings helps to ensure that each seedling can receive sunlight, which is beneficial to the growth of the seedlings. In this embodiment, the second preset length ranges from 0.1m to 0.15m, and the third preset height ranges from 1m to 1.2m. Preferably, the second preset length is 0.1m and the third preset height is 1m.

[0061] Step S7: In the winter of the second year of the growth of the seedlings, each bud is subjected to single bud pruning to control the tree shape until the tree bears fruit.

[0062] Among them, in step S7, single bud pruning is performed on each sprout, which can prevent the fruiting part from moving upward and help control the consistency of the fruiting part. At the same time, the seedlings have grown to an appropriate height at this time, and only the fruiting part needs to be controlled each year to ensure consistency of the fruiting part.

[0063] In addition, in this embodiment, when the height of the sprout grows to the fifth preset height, the second rack is tied, and when the height of the sprout grows to the sixth preset height, the third rack is tied. The second and third racks are set so that the vines of the seedlings can grow vertically upward during growth, wherein the fifth preset height ranges from 0.83m to 0.87m, and the sixth preset height ranges from 1.33m to 1.37m. Preferably, the fifth preset height is 0.83m and the sixth preset height is 1.33m.

[0064] In this embodiment, wine grape seedlings planted in the Changli area of ​​Qinhuangdao are taken as an example to introduce the wine grape planting method in this embodiment. First, dig pits with a row spacing of 2.5m and a plant spacing of 0.7m, plant the seedlings in the pits and fill them with soil, measure the main vine of the seedlings, and when the height of the main vine grows to 0.4m, pinch the tip of the main vine to control the height of the main vine at 0.35m, and retain two branch vines on both sides of the main vine. Tie the two branch vines with wire so that the branch vines and the main vine are in a T-shaped frame. In the winter of the first year of the seedlings' growth, trim the length of the branch vines to 0.3m, and bury the seedlings in the soil to prevent cold. The cold-proof soil is buried to a height of 0.45m from the ground. In the spring of the second year of the seedlings' growth, use an excavation machine to remove the seedlings. The seedlings are unearthed, and grooves with a depth of 0.1m and a width of 0.2m are formed on both sides of the main vine. After the buds are removed from the branch vines and the suckers of the main vines are cleared, the land on both sides of the main vines is leveled, covered with a membrane structure, and fixed. In the spring of the second year of seedling growth, the length of the sprouts on the branch vines is controlled at 0.1m, and the height of the leaf curtain is controlled at 1m. At the same time, when the seedlings grow to 0.83m, the second frame is tied with wire, and when the seedlings grow to 1.33m, the third frame is tied with wire. In the winter of the second year of seedling growth, each sprout is pruned individually to ensure the fruiting position, and then pruned every year to ensure that the fruiting position remains unchanged.

[0065] The wine grape planting method in this embodiment helps to ensure that each seedling can obtain sufficient sunlight by planting wine grape seedlings at fixed row and plant spacings, and helps to reduce the number of times the seedlings are put on and taken off the shelves after being tied up on the shelves and then directly buried in the soil to protect them from cold in winter, which helps to help the seedlings take shape in one year and bear fruit in the second year, which helps to ensure the growth of the seedlings. By pruning single buds, it helps to ensure balanced nutrition distribution of wine grapes, which helps to ensure the yield of wine grapes. By covering the ground on both sides of the main vine with a membrane structure, it is beneficial to retain water for the main vine planting, prevent the growth of weeds, and reduce the risk of diseases caused by soil splashing and contaminating the fruit surface during the rainy season, which helps to improve the yield and quality of wine grapes.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
