[0028] The preferred embodiments of the present application will be described in more detail below. Although the preferred embodiments of the present application are described below, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. If a specific technique or condition is not specified in the examples, the technique or condition described in the literature in the art or according to the product manual is used. If the manufacturer of the reagent or instrument is not specified, it is a conventional product that can be obtained by purchase on the market. In the following examples, unless otherwise specified, "%" refers to the percentage by weight.

[0029] Example 1

[0030] During grape winter pruning in January and February, select and leave healthy branches with full winter buds and no diseases for cutting, the cutting thickness is 9.5-12 mm, cut into three sections, containing three bud eyes, the cutting length is 35-45 cm, the lower end of the branch is immersed in growth regulator (500 ppm indole butyric acid) for 5 minutes, and then cut into 15-18 cm small plastic pots with holes.

[0031] Specifically, the cutting with one bud eye with a length of 8-12 cm is inserted into the substrate soil, and the upper two sections are left. The substrate soil is selected from peat soil + perlite, with a ratio of 50% each. This substrate soil is loose and breathable, which is conducive to root growth. After cutting, the soil is watered thoroughly, and the substrate is kept moist, and appropriate shading is provided.

[0032] Rooting occurs about 20 days after cutting, and grape branches sprout are observed 40 days after cutting. The top bud is selected and left to grow into a branch, and flower buds appear 50 days after cutting, as shown in Figure 1As shown; at this time, long roots grow from the root, as... Figure 2 As shown, this indicates that the cuttings are growing vigorously. The flower spikes emerging from the top branch should be retained, while the rest should be removed. The second node bud should be pinched back to four leaves to promote nutrient accumulation, which is beneficial for flowering of the top branch flower spikes and fruit development.

[0033] When the buds appear, the roots are already at the bottom of the small pot. Sixty days after planting, transplant the small pot directly into a 38cm diameter pot. Figure 3 As shown. The substrate soil for the large pot is garden soil + peat moss + perlite (mass ratio 2:1:1). When potting, there is no need to prune the roots or remove the plant from the pot, so as not to damage the roots. The roots and soil will not be loosened, the growth environment will not change, and the stability of the flower buds can be maintained. After potting, strengthen the management of fertilizer and water and the prevention and control of diseases and pests.

[0034] After potting, pinch off the top 4 leaves above the flower spike, and pinch off the top 1 leaf of each lateral shoot to allow nutrients to flow back to the flowers. Because it's a potted, root-limited cultivation method, the grapevines won't grow excessively. After the flowers are fully open, use a fruit-setting agent (a 1:1 mixture of chlorpyrifos and gibberellic acid) to retain the fruit. Afterward, apply foliar fertilizer weekly, using a high-element fertilizer and boron fertilizer in a 3:1 ratio. Observe the fruit nearing maturity 110 days after planting. Figure 4 , Figure 5 As shown, the plants can be potted and harvested 4 months after planting.

[0035] Example 2

[0036] During the winter pruning of grapes in January and February, select healthy branches with plump winter buds and no diseases or pests to be used as cuttings. The cuttings should be 9.5-12mm in diameter, cut into three sections with three buds, and each cutting should be 35-45cm long. After soaking the lower end of the cuttings in a growth regulator (600ppm indolebutyric acid) for 5 minutes, insert them into a 15-18cm non-woven fabric bottomless substrate bag.

[0037] Specifically, insert cuttings with one bud and a length of 8-12cm into the substrate soil and compact them, leaving two nodes on top. The substrate soil should be a mixture of peat moss and perlite, each accounting for 50%. This substrate soil is loose and breathable, which is conducive to root growth. Water thoroughly immediately after cutting and keep the substrate moist, and provide appropriate shade.

[0038] Roots develop approximately 20 days after insertion, and buds are observed sprouting from the grapevines 40 days later. Select the terminal bud and allow it to grow into a branch; flower buds appear 52 days after insertion. At this time, long roots have grown from the base, indicating vigorous growth of the cutting. Retain the flower spikes emerging from the terminal branch and remove the rest. Pinch off the second node bud when it has four leaves to promote nutrient accumulation, which is beneficial for flowering of the terminal flower spike and fruit development.

[0039] The roots have grown out of the bag bottom at the present bud stage, and 65 days after the insertion, the plants with the bags are directly potted in a 40 cm diameter pot. The substrate soil of the large pot is garden soil + peat soil + perlite (mass ratio 2:2:1). When the plants are potted, the roots are not damaged, the root system is not loose, the growth environment does not change, and the stability of the flower buds can be maintained. After the plants are potted, the fertilization and water management and the disease and pest control are strengthened.

[0040] After the plants are potted, the upper part of the flower spikes is left with 4 leaves and pinched, and all the secondary shoots are left with 1 leaf and pinched, so that the nutrients are returned to the flowers. Since it is a potted limited root cultivation, the grapevine tendrils will not grow excessively. After the flowers are fully opened, the plants are treated with a fruit retention agent (a mixture of forchlorfenuron and gibberellin according to a mass ratio of 1:2) to retain the fruits. Then, the plants are fertilized once a week with a large amount of element fertilizer and boron fertilizer according to a mass ratio of 3:1. 110 days after the insertion, it is observed that the fruits are close to maturity, and 4 months after the insertion, the plants can be potted for ornamental and picked.

[0041] Comparative Example 1

[0042] With reference to Example 1, the difference is that the plastic pots with holes are not used when the cuttings are taken, but the cuttings are taken on a seedbed, and the specific steps are as follows.

[0043] During the grape winter pruning in January and February, the cuttings are taken from the winter buds that are full, healthy, and free of diseases and pests. The cuttings are 9.5-12 mm in thickness, cut into three sections, contain three bud eyes, and are 35-45 cm in length. The lower end of the cutting is immersed in a growth regulator (500 ppm indole butyric acid) for 5 minutes, and then the cutting is inserted into a 15-18 cm seedbed.

[0044] Specifically, the cutting with one bud eye and 8-12 cm in length is inserted into the seedbed and compacted, and the upper two sections are left. The seedbed soil is selected from peat soil and perlite, and the two account for 50% respectively. The substrate soil is loose and breathable, which is beneficial to root growth. The cutting is immediately watered after the insertion, and the substrate is kept moist. The cutting is appropriately shaded.

[0045] The cutting is rooted about 20 days after the insertion, and the grape branches sprout 40 days after the insertion. The top bud is selected and left to grow into a branch, and the flower buds appear 60 days after the insertion. At this time, the roots grow into root hairs. The flower spikes generated from the top branch are retained, and the rest of the flower spikes are removed. The second section of the bud is pinched to 4 leaves to promote nutrient accumulation, which is beneficial to the flowering of the top branch and the development of the fruits.

[0046] The cutting is transplanted 60 days after the insertion. The cutting is dug out from the seedbed and transplanted into a 38 cm diameter pot. The substrate soil of the large pot is garden soil + peat soil + perlite (mass ratio 2:1:1). After the plants are potted, the fertilization and water management and the disease and pest control are strengthened. It is observed that the grape plants survive in the later period, but there are few fruits, and the fruits fall off seriously. No mature grape is harvested in the same year.

[0047] The preferred embodiments of the present application are described in detail above, but the present application is not limited to the specific details of the above-described embodiments, and various simple modifications can be made to the technical solutions of the present application within the technical concept of the present application, and these simple modifications all belong to the protection scope of the present application.

[0048] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, various possible combinations are not described again by the present application.

[0049] In addition, various different embodiments of the present application can also be combined in any manner, as long as it does not deviate from the idea of the present application, and it should also be considered as disclosed by the present application.
