Abstract
Description
Technical Field
[0001] This invention belongs to the field of flower cultivation technology, and in particular relates to a method for pruning cut rose bushes. Background Technology
[0002] Currently, the pruning method for cut roses mostly adopts the cultivation of nutrient branches. When the cut flower branches mature, they are cut off one by one. When pruning, 1-2 buds are left at the base of the stem to produce a second batch of flowers, which is the second-level cut flower branch, and so on. However, this pruning method for cut roses has the following shortcomings: (1) The higher up the cut roses go, the thinner the branches become. After the fifth batch of flowers, the thickness of the branches will not be able to meet the needs of obtaining more and higher quality flower branches in the later stages. 70% of the cut flower branches will lose their commercial value and need to be pruned again; (2) Each time the flower branches are pruned, only 1-2 buds are left, that is, 1-2 compound leaves are left. The effective photosynthetic leaf area is insufficient. The nutrients produced by the photosynthesis of the nutrient branches can only supply about 3 commercial cut flower branches per plant. If more branches are left, the cut flower branches will not have enough nutrients and it will be difficult to produce high-quality cut flowers; (3) Due to the limited number of cut flower branches, the space between plants is not fully utilized.
[0003] Therefore, in order to improve the yield and quality of cut roses in the later stages and to ensure uniform flowering, it is necessary to find a new pruning method based on the existing pruning methods for cut roses. Summary of the Invention
[0004] To solve the above-mentioned technical problems, this invention proposes a method for pruning cut rose bushes.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] This invention provides a method for pruning cut rose bushes, comprising the following steps:
[0007] (1) When the cut flower branches of the cut rose reach a height of 30-40 cm and are in the red stripe stage, cut the branch from the top of the plant down to the first branch with ≥7 leaflets of compound leaves, and cut off the top branches with ≤5 leaflets of compound leaves.
[0008] (2) After pruning, the cut flower branches will sprout multiple axillary buds. Keep the two uppermost axillary buds and remove the excess axillary buds. The retained axillary buds will develop into the first batch of flower branches.
[0009] (3) After the first batch of flower branches is harvested, the cutting branches are cut off two nodes below the top of the cutting branches, and the second batch of flower branches is cultivated until the cutting branches are used up, and then the cutting branches are cultivated again.
[0010] Technical Principle: This invention involves pruning cut rose bushes when they reach a height of 30-40 cm, before the stems become woody and the leaves turn green (red stripe stage). The pruning is performed on the first branch with at least 7 leaflets (compound leaves) from the top of the plant. The portion of the top branch with at least 5 leaflets is removed (i.e., a red stub is cut). The remaining branch is left as a stub, allowing it to continue photosynthesis and providing nutrients for new flower shoots, promoting better growth and development. This solves the problem of insufficient nutrition in traditional pruning methods, which prevents high-quality cut flowers. Simultaneously, the cut rose bushes will sprout multiple axillary buds after the red stub is cut. The top two axillary buds are retained for development, meaning one cut rose bush produces two flowers, increasing the yield of cut roses compared to traditional pruning methods. Furthermore, cut rose bushes with inconsistent growth can be pruned simultaneously, resulting in very uniform bud growth, facilitating management and ensuring even flowering.
[0011] Furthermore, in step (1), the cut flower branch is a new bud that grows from the central pressing point of the plant after the nutrient branch cultivation is completed.
[0012] Furthermore, the method for cultivating the cut flower branches includes the following steps:
[0013] A. Plant cut roses in two rows in the middle of the soil surface;
[0014] B. When the cut rose bushes reach a height of 30-40 cm, press the double-row cut rose bushes to both sides of the soil surface to retain them as nutrient branches, thus completing the cultivation of nutrient branches;
[0015] C. After the nutrient branches are cultivated, new buds will grow, which are then used as cut flower branches.
[0016] Furthermore, in step A, the width of the soil surface is 50-60 cm; the distance between two adjacent rose bushes in the same row is 15-20 cm.
[0017] Furthermore, in step (1), the red stripe period refers to the period before the stems of the cut flower branches become lignified and the leaves turn green.
[0018] Furthermore, in step (1), flower branches of different heights are cut and stumped simultaneously.
[0019] Furthermore, in step (2), the axillary buds of the cut flower branch sprout at a position 2-3 nodes below the cut.
[0020] Furthermore, in step (2), the number of axillary buds is 2 to 3.
[0021] Furthermore, in steps (2) and (3), the number of the first batch of flower branches and the second batch of flower branches are both 2.
[0022] Compared with the prior art, the present invention has the following advantages and technical effects:
[0023] The pruning method for cutting rose stumps provided by this invention involves cutting off the top part of the primary cut flower branches, leaving the remaining branches as stumps to continue photosynthesis, increasing the photosynthetic area, and providing nutrients for the newly generated secondary cut flower branches (i.e., the first batch of flower branches) on the stumps, allowing the secondary cut flower branches to grow and develop better. From the ground part to the stump position, there are generally 6 to 7 nodes, which is 6 to 7 more leaves than the traditional pruning method. The nutrients produced by the photosynthesis of these 6 to 7 leaves can be directly supplied to the secondary cut flower branches, allowing the secondary cut flower branches to develop better. After the secondary cut flower branches are harvested, the branches are pruned down two nodes until all the cut flower branches are used up, and then new cut flower branches are cultivated, and so on.
[0024] After pruning, the cut flower branches will sprout multiple axillary buds. Excess axillary buds are removed, leaving only the top two for development. This allows one cut flower branch to produce two flowers, increasing the yield of cut roses. Furthermore, cut rose plants with inconsistent uniformity can be pruned simultaneously, resulting in very uniform bud growth, facilitating management and ensuring even flowering. The pruning time can also be adjusted based on the variety's flowering time, ensuring flowers are produced at the desired blooming period and stabilizing the flowering time of cut roses. Experimental results show that the pruning method provided by this invention not only avoids short branches but also significantly increases the branch length of cut flower branches and significantly improves the proportion of Grade A flowers, thus consistently increasing the yield and quality of cut roses.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0033] This invention provides a method for pruning cut rose bushes, comprising the following steps:
[0034] (1) When the cut flower branches of the cut rose reach a height of 30-40 cm and are in the red stripe stage, cut the branch from the top of the plant down to the first branch with ≥7 leaflets of compound leaves, and cut off the top branches with ≤5 leaflets of compound leaves.
[0035] (2) After pruning, the cut flower branches will sprout multiple axillary buds. Keep the two uppermost axillary buds and remove the excess axillary buds. The retained axillary buds will develop into the first batch of flower branches.
[0036] (3) After the first batch of flower branches is harvested, the cutting branches are cut off two nodes below the top of the cutting branches, and the second batch of flower branches is cultivated until the cutting branches are used up, and then the cutting branches are cultivated again.
[0037] In a preferred embodiment, in step (1), the cut flower branch is a new bud that grows from the central branch-pressing point of the plant after the vegetative branch cultivation is completed. The pruning method provided by the present invention is carried out on the basis of the completion of traditional vegetative branch cultivation.
[0038] In a preferred embodiment, the method for cultivating the cut flower branches includes the following steps:
[0039] A. Plant cut roses in two rows in the middle of the soil surface;
[0040] B. When the cut rose bushes reach a height of 30-40 cm, press the double-row cut rose bushes to both sides of the soil surface to retain them as nutrient branches, thus completing the cultivation of nutrient branches;
[0041] C. After the nutrient branches are cultivated, new buds will grow, which are then used as cut flower branches.
[0042] In a preferred embodiment, in step A, the width of the soil surface is 50-60 cm; the distance between two adjacent rose bushes in the same row is 15-20 cm; and the row spacing between two adjacent rows of rose bushes is 40-45 cm.
[0043] In a preferred embodiment, in step (1), the red stripe period refers to the period before the stems of the cut flower branches become lignified and the leaves turn green. This invention, by pruning during the red stripe period, preserves 6-7 nodes from the above-ground portion to the pruning cut, leaving these nodes as stubs. These stubs can then provide nutrients for newly generated secondary cut flower branches through photosynthesis, allowing the secondary cut flower branches to grow and develop better.
[0044] In a preferred embodiment, in step (1), cut flower branches of different heights are pruned simultaneously. The pruning method provided by this invention can prune cut flower rose plants with inconsistent uniformity at the same time, resulting in very uniform buds that sprout later, which facilitates agricultural management and allows for neat flowering.
[0045] In a preferred embodiment, in step (2), the axillary buds of the cut flower branch sprout at a position 2-3 nodes below the cut.
[0046] In a preferred embodiment, in step (2), the number of axillary buds is 2 to 3.
[0047] In a preferred embodiment, in steps (2) and (3), the number of the first batch of flower branches and the second batch of flower branches are both 2. This invention cultivates two flowers from one cut flower branch by retaining the two uppermost sprouting axillary buds, which increases the yield of cut flower roses compared to traditional pruning methods.
[0048] Example 1
[0049] A method for pruning cut rose bushes into red stems, the specific steps are as follows:
[0050] (1) Ditch and prepare the soil. The soil surface is 60 cm wide and the ditch is 60 cm wide. Cut roses are planted in two rows in the middle of the soil surface. The distance between two adjacent roses in the same row is 20 cm and the row spacing between two adjacent rows of roses is 40 cm.
[0051] (2) When the cut roses grow to a height of 40 cm, the growth period of the nutrient branches is completed. Then, the double-row cut rose plants are pressed to both sides of the soil surface to be retained as nutrient branches. After the cultivation of nutrient branches is completed, new buds will grow from the center of the nutrient branches, which are the cut flower branches.
[0052] (3) When the cut flower branches grow to a height of 40 cm and the leaves have not yet turned green (red stripe stage), prune the branch from the top of the plant down to the first branch with 7 leaflets (see the pruning location). Figure 3 Cut off the top branches with 5 leaflets of compound leaves.
[0053] (4) After cutting the stub, the cut flower branch will sprout 2-3 axillary buds 2-3 nodes down from the cut. Remove the bottom axillary bud and leave only the top two axillary buds to develop, thus obtaining the first batch of flower branches.
[0054] (5) After the first batch of flower branches is harvested, cut the branches two nodes down from the top of the cut flower branches and continue to cultivate the second batch of flower branches until all the cut flower branches are used up, and then cultivate new cut flower branches.
[0055] Comparative Example 1
[0056] A method for pruning cut roses (traditional pruning method), the specific steps are as follows:
[0057] (1) Ditch and prepare the soil. The soil surface is 60 cm wide and the ditch is 60 cm wide. Cut roses are planted in two rows in the middle of the soil surface. The distance between two adjacent roses in the same row is 20 cm and the row spacing between two adjacent rows of roses is 40 cm.
[0058] (2) When the cut roses grow to a height of 40 cm, the growth period of the nutrient branches is completed. Then, the double-row cut rose plants are pressed to both sides of the soil surface to be retained as nutrient branches. After the cultivation of nutrient branches is completed, new buds will grow from the center of the nutrient branches. After development, the first batch of flower branches will be obtained.
[0059] (3) When harvesting the first batch of flower branches, leave 1-2 buds at the base of the stem for the development of the second batch of flower branches, and so on.
[0060] Figure 1 This is a schematic diagram of the traditional pruning method in Comparative Example 1, where 1 represents the cut flower branch and 2 represents the base stake. From Figure 1 It can be seen that the traditional pruning method can only produce one flower from one cut flower branch, resulting in a low yield.
[0061] Figure 2 This is a schematic diagram illustrating the pruning method for cutting rose branches according to the present invention, wherein 1 represents the cut flower branch, 2 represents the base branch, 3 represents the soil surface, and 4 represents the nutrient branch. Figure 2 It can be seen that the pruning method provided by the present invention can cultivate two flowers using only one cut flower branch, thereby increasing the yield of cut flower roses.
[0062] Figure 3 This is a physical image of the cut position after the pile is cut in step (3) of embodiment 1 of the present invention. The left image shows the remaining pile opening, and the right image shows the cut top. Figure 3 It can be seen that the pruning method provided by the present invention removes the top branches with ≤5 leaflets of compound leaves when the cut flower branches are in the red stripe stage, leaving 6 to 7 nodes from the ground to the red stripe stake, which can provide nutrition for the newly generated secondary cut flower branches on the stake.
[0063] Planting trials:
[0064] The cut rose variety was Peach Snow Mountain. A planting experiment was conducted on the same plot of land, using the pruning methods of Example 1 and Comparative Example 1 respectively. The plant height, stem diameter, and the proportion of A, B, C, and D grade flowers were statistically analyzed under the two different pruning methods. The results are shown in [Figure 1]. Figure 4 and Figure 5 .
[0065] Figure 4 This is a comparison of plant height and stem diameter of cut roses under two different pruning methods, Example 1 and Comparative Example 1. The left image shows plant height, the right image shows stem diameter, the flat bar represents Comparative Example 1, the red bar represents Example 1, and different lowercase letters indicate significant differences. Figure 4 It can be seen that the plant height and stem diameter of the flower branches obtained by the pruning method provided by the present invention are significantly greater than those of Comparative Example 1, indicating that the pruning method provided by the present invention can improve the quality of cut roses.
[0066] Figure 5 This is a statistical chart showing the proportion of cut roses of grades A, B, C, and D under two different pruning methods, namely Example 1 and Comparative Example 1. The left chart represents Comparative Example 1, and the right chart represents Example 1. From... Figure 5 It can be seen that the proportion of Grade A flowers in the flower branches obtained by the pruning method provided by the present invention is significantly higher than that in Comparative Example 1, with Grade A flowers reaching more than 80%, indicating that the pruning method provided by the present invention can improve the quality of cut roses.
[0067] The above results show that, compared with traditional pruning methods, the pruning method for cutting roses with red stubble provided by this invention can increase the yield of cut roses by about 16,000 to 25,000 flowers per acre, and the proportion of Grade A flowers is significantly increased, reaching more than 80%. This indicates that the pruning method provided by this invention can simultaneously improve the yield and quality of cut roses.
[0068] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
