Description

Technical Field

[0001] This invention relates to the field of high-efficiency fruit tree cultivation technology, and in particular to a method for improving the hollow structure of kiwifruit orchards. Background Technology

[0002] Kiwifruit, rich in nutrients and vitamin C, is known as the "King of Fruits" and is highly favored by consumers. Currently, kiwifruit is grown in 23 provinces in my country, with a cultivation area exceeding 4 million mu (approximately 667,000 hectares). As the cultivation period of kiwifruit extends and newly established orchards gradually enter the fruiting stage, problems in cultivation management are becoming increasingly prominent. One such problem is the increasingly serious issue of empty fruit vines in kiwifruit orchards. This is mainly manifested in the lack of suitable renewal branches within the area within the first wire of the trellis (i.e., the area 50cm on each side of the main vine; in production, the first wire is usually located 50cm on each side of the main vine along the row direction, and the second wire is located 100cm on each side of the main vine). Fruiting branches continuously shift outwards, and in severe cases, there are no effective fruiting branches within the second wire. This prevents branches from fully covering the trellis, resulting in insufficient fruiting branches and fruit length, inevitably affecting fruit yield. Consequently, orchards generally experience low yields, reduced economic benefits, and are detrimental to the healthy development of the industry. Therefore, there is an urgent need to develop an effective method to improve the hollow fruit phenomenon in kiwifruit orchards, increase the number and length of effective fruiting branches, expand the effective fruiting area, ensure fruit yield, and stabilize the economic benefits for growers. Summary of the Invention

[0003] This invention provides a method for improving the hollow fruit structure in kiwifruit orchards.

[0004] The solution of the present invention is:

[0005] A method for improving hollow fruit in kiwifruit orchards includes the following steps:

[0006] 1) Double-notched buds on the main vine;

[0007] 2) Treatment methods for branching agents;

[0008] 3) Management of newly sprouted branches in the current year;

[0009] 4) Pruning and renewal of newly sprouted branches.

[0010] As a preferred technical solution, the method of double-notching buds on the main vine is as follows: Select a suitable position on the main vine of kiwifruit where branches are lacking in the inner canopy and branches need to be added. Select a suitable dormant bud. Before the normal buds sprout each year, make a cut with a saw blade 0.5-1.0cm in front of the dormant bud. The cut should be 1mm wide and 1 / 3 the length of the branch, reaching the xylem. Make a second cut similar to the first cut on the lower part of the branch 1.0cm away from the front of the first cut. This is the double-notching bud operation.

[0011] As a preferred technical solution, with the main stem of the kiwifruit as the axis, the space between the first branch on one side of the main vine away from the axis and the axis is more than 40cm, which is the position where the double bud incision operation needs to be performed; the first wound tip is along the growth direction of the branch; 1.0cm away is on the lower part of the branch, which is the back of the branch 1.0cm away from the first wound position.

[0012] As a preferred technical solution, the treatment method for the branching agent (2) is as follows:

[0013] Apply liquid branching agent to the dormant buds on which you are notching, ensuring that the agent completely soaks into the bud. Apply once, then wrap the buds with plastic film to keep them moist and water them promptly.

[0014] Alternatively, a drop of liquid branching agent can be applied to the bud using a pipette. After the branching agent treatment, the bud can be wrapped with a plastic film to retain moisture, and the tree should be watered promptly. The pipette can be either a pipette or a pipette tube.

[0015] As a preferred technical solution, the management method for newly sprouted branches in the current year in step 3) is as follows:

[0016] After bud notching and treatment with a branching agent to induce dormant buds to sprout new shoots, the plastic film is removed, and the new shoots are wrapped in regular white fruit bags. Every 7 days, the bags are opened and a nutrient solution is sprayed. After spraying, the solution is allowed to dry, and the bags are re-wrapped to promote rapid growth of the new shoots. This process is repeated 3-4 times. When the shoots grow to more than 40cm in length, the white fruit bags are removed, and a mixed solution is sprayed every 7 days until the new shoots become semi-lignified. At this point, the mixed solution is no longer sprayed, and the shoots are allowed to grow naturally. This process continues until the new shoots become semi-lignified by the end of July of that year.

[0017] As a preferred technical solution, the nutrient agent includes potassium dihydrogen phosphate at a concentration of 0.05% and indolebutyric acid at a concentration of 750 mg / L, which can be sprayed separately or mixed together before spraying.

[0018] As a preferred technical solution, the mixture comprises 0.2% potassium dihydrogen phosphate, 1000 mg / L indolebutyric acid, and 1500 mg / L chlormequat chloride (CCC).

[0019] As a preferred technical solution, the pruning and renewal method for newly sprouted branches in step 4) is as follows:

[0020] After the new shoots have fallen leaves and gone dormant in winter, prune them back to 4 plump buds. In the following spring, after the plump buds have sprouted and grown slightly, retain 1-2 strong and vigorous branches with suitable orientations for cultivation and renewal (depending on the situation of empty branches and the location of branches to be added). Remove other weak branches and guide the branches to fill the empty spaces by timely tying the vines, thereby improving the empty branches phenomenon in the orchard.

[0021] The above-mentioned technical solution is a method to improve the hollow branches of kiwifruit orchards, which includes: 1) double-cut buds on the main vine; 2) treatment method of branching agent; 3) management of newly grown branches in the current year; and 4) pruning and renewal of newly grown branches.

[0022] Advantages of this invention:

[0023] 1) It is simple to operate and easy to learn and master. Even growers with some orchard management experience can quickly master it in a short period of time.

[0024] 2) It significantly increases the effective fruiting area and the length of fruiting branches in kiwifruit orchards, which has a significant effect on ensuring fruit yield;

[0025] 3) This method will not significantly increase the manpower required for orchard management, as the operations involved are all routine orchard management procedures.

[0026] This invention can significantly improve the appearance of kiwifruit orchards with severe hollow fruit, increase the effective fruiting area and the number and length of fruiting branches, and improve fruit yield, playing an important role in ensuring the economic benefits of growers. It is also of great significance for promoting the healthy and sustainable development of the kiwifruit industry. Detailed Implementation

[0027] This invention provides a method for improving the hollow fruit production in kiwifruit orchards to solve the problems mentioned in the background art.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific embodiments.

[0029] Example:

[0030] A method for improving hollow fruit in kiwifruit orchards includes the following steps:

[0031] 1) Double-notched bud on the main vine: The method for performing double-notched bud on the main vine is as follows: Select a suitable location on the main vine of the kiwifruit where branches are lacking in the inner canopy and branches need to be added. Select a suitable dormant bud. Before the normal bud sprouts each year, make a cut 0.5-1.0cm in front of the dormant bud with a saw blade. The cut should be 1mm wide and 1 / 3 the length of the branch, reaching the xylem. Make a second cut similar to the first cut 1.0cm away from the front of the first cut on the lower part of the branch. This is the double-notched bud operation. With the main kiwifruit trunk as the axis, the space on the first branch on the main vine that is more than 40cm away from the axis is the location where the double-notched bud operation needs to be performed. The front of the first cut is along the growth direction of the branch. The 1.0cm distance on the lower part of the branch is 1.0cm away from the first cut on the back of the branch.

[0032] 2) Treatment method of branching agent: Use a cotton swab to dip in liquid branching agent and apply it to the dormant buds to be notched, ensuring that the branching agent completely soaks into the bud. Apply once, and after treatment, wrap with plastic film to keep it moist and water the tree in time.

[0033] Alternatively, a drop of liquid branching agent can be applied to the bud using a pipette. After the branching agent treatment, the bud can be wrapped with a plastic film to retain moisture, and the tree should be watered promptly. The pipette can be either a pipette or a pipette tube.

[0034] 3) Management of newly sprouted branches in the current year: After bud notching and treatment with branching agent to induce the emergence of new branches from dormant buds, remove the plastic film and wrap the new shoots with conventional white fruit bags. Open the bags every 7 days and spray with a nutrient solution. After spraying, allow the liquid to dry, then re-wrap with white fruit bags to promote rapid growth of new branches. Repeat this process 3-4 times. When the branches grow to more than 40cm in length, remove the white fruit bags and spray with a mixed solution every 7 days until the new branches are semi-lignified. Stop spraying the mixed solution and allow them to grow naturally. This process continues until the new branches reach semi-lignification by the end of July of the same year. The nutrient solution consists of 0.05% potassium dihydrogen phosphate and 750mg / L indolebutyric acid. The mixed solution consists of 0.2% potassium dihydrogen phosphate, 1000mg / L indolebutyric acid, and 1500mg / L chlormequat chloride (CCC).

[0035] 4) Pruning and renewal of new branches: After the new branches have fallen leaves and gone dormant in winter, prune them back to 4 plump buds. In the second spring, after the plump buds have sprouted and grown out, retain 1-2 strong branches with suitable direction for cultivation and renewal (depending on the situation of empty branches and the position of branches to be added). Remove other weak branches and guide the branches to fill the empty positions by timely tying the vines to improve the empty branches phenomenon in the orchard.

[0036] experiment

[0037] An experiment was conducted in two adjacent fields within the same orchard where both had hollowed-out areas. These fields were divided into experimental and control fields, with the same planting area, kiwifruit row spacing of 4 meters, and the same number of kiwifruit plants. The experimental field was maintained using the method of this invention, while the control field was not. All other planting methods were the same.

[0038] After the harvest, it was found that the yield per mu of the experimental field was more than 240 kg higher than that of the control field.
