Description

Technical Field

[0001] The invention belongs to the field of flower cultivation, and particularly relates to a Gloriosa lily cutting method based on pruning and retaining branches. Background Art

[0002] Gloriosa lily, also known as flame lily, is a perennial climbing herbaceous flower of the genus Gloriosa in the Liliaceae family. Gloriosa lily has a long flowering period, and its flowers and leaves are beautiful. It can be placed indoors for a long time and has high ornamental value and market development prospects. In recent years, fresh cut flowers of Gloriosa lily have been very popular in the market due to their unique flower shape and bright colors. In the international market, broad-petaled Gloriosa lily has been commercially produced as high-end cut flowers and potted flowers, especially in Europe and the United States, where its introduction as fresh cut flowers has been warmly welcomed. However, due to the relative difficulty in planting and cultivating Gloriosa lily, the price of its fresh cut flowers has remained high.

[0003] The common cultivation method of Gloriosa lily is to use a shed or metal frame to hang vines, with one hanging rope for each Gloriosa lily, and only the main branches are kept as cut flowers. However, the current method of producing Gloriosa lily as fresh cut flowers has the following two problems:

[0004] (1) The cultivation method of Gloriosa lily is to only retain the main branches. Each bulb can only produce one cut flower, which has a low yield. In addition, the cost of purchasing Gloriosa lily bulbs is high. The profit of cultivating Gloriosa lily mainly depends on self-propagation of bulbs to reduce the cost of bulbs.

[0005] (2) Some varieties of Gloriosa lily with low flowering nodes and short plant height can only grow to 1.2-1.5m and can only produce branches 60-70cm in length, which is not of excellent quality. Summary of the invention

[0006] In order to solve the above technical problems, the present invention discloses a Gloriosa lily cut flower method based on pruning and retaining branches, so that the same Gloriosa lily bulb can produce 2-3 branches of cut flowers, thereby improving the yield, and can increase the flowering nodes of early-flowering varieties with lower plant height, thereby producing longer and higher-quality flower branches.

[0007] The main technical solutions adopted in the present invention are:

[0008] A method for cutting Gloriosa lily flowers based on pruning and retaining branches, the specific method is as follows:

[0009] S1: When lateral buds first appear on Gloriosa lily, if the main branch is retained, remove the other lateral buds and only retain the two opposite lateral buds; if the main branch is not retained, remove the other lateral buds and retain the two opposite or non-opposite lateral buds;

[0010] S2: When the side branches grow to a certain length, they are fixed obliquely or lifted up and fixed upright according to the natural growth direction of the side branches. If the main branches are retained, the main branches are kept upright and fixed, and step S3 is performed; if the main branches are not retained, the processing of the main branches is ignored, and step S3 is directly skipped to step S4;

[0011] S3: Regularly remove some flower buds on the main branches to make the flowering time of the side branches grown from the side buds basically consistent with the main branches;

[0012] S4: When side buds appear on the side branches, remove all side buds. If the side branches are fixed obliquely, lift the side branches and fix them in the vertical direction again;

[0013] S5: If the main branch is retained in step S1, the side branches and the main branch are harvested together when both meet the harvesting standard. If the main branch is not retained in step S1, the side branches can be harvested when they meet the harvesting standard.

[0014] Preferably, in S3, the number of flower buds removed from the main branch is 6-7.

[0015] Preferably, the planting method of the Gloriosa lily is hanging vine cultivation or grid cultivation.

[0016] Preferably, in S2, the specific method of performing oblique fixing according to the natural growth direction of the side branches is: maintaining the natural growth angle of the side branches, providing support through a grid or hanging ropes, so that the side branches maintain an angle of 45°-60° with the vertical direction.

[0017] Preferably, in S4, the specific method of lifting the side branch and re-fixing it in the vertical direction is to loosen or not loosen the previous fixed position, adjust the branch angle of the side branch to the upright direction, and re-support and fix it by a grid or hanging vine.

[0018] Beneficial effects: The present invention provides a method for cutting Gloriosa lily flowers based on pruning and retaining branches, which has the following advantages compared with the prior art:

[0019] (1) The present invention retains some lateral buds for cultivation during the cultivation process, so that the lateral branches grow into branches that can be used as cut flowers, and one bulb can produce 2-3 branches of cut flowers. Compared with the existing pruning method that only retains the main branches, the output of cut flowers can be significantly increased, the average cost of purchasing bulbs can be reduced, and the production efficiency can be improved.

[0020] (2) The present invention improves the flowering node position by cultivating side branches and removing the flower buds at the bottom of the main branch when adjusting the flowering time of the main branch, so that the actual flowering position (i.e., the first flower branch retained) is increased by about 40-60 cm, and the plant height of early-flowering varieties with shorter plant height can be increased from 1.2-1.5 m to more than 1.7 m, thereby stably producing 80-90 cm high-quality flower branches.

[0023] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0024] Example 1

[0025] In this Example 1, Gloriosa lily (variety A) was planted on April 20, 2023, lateral buds began to appear at the growth point on May 15, and flower buds appeared on May 23, at which time the experimental group and the control group began to undergo different treatments.

[0026] All lateral buds were removed from all plants in the control group.

[0027] In order to maintain the same planting density as the control group, only half of the experimental group was treated with side branches to increase yield, and the other half was treated with all side buds removed and only the main branches left, as in the control group. Two adjacent trees were treated differently, and the two treatments were performed alternately. Among them, in this embodiment 1, the specific treatment method of the side branch treatment to increase yield is as follows:

[0028] Step 1: Keep the main branch, remove other side buds, and only keep two opposite side buds;

[0029] Step 2: When the side branches grow to a certain length (about 30 cm), in order to save space, in this embodiment 1, the side branches are lifted up and fixed upright, and the main branches are kept upright and fixed, and the side branches are basically parallel to the main branches. In this embodiment 1, the side branches grow to a certain length means that the side branches have a certain length but have not begun to droop due to gravity, and generally about 30 cm is a more suitable length.

[0030] Step 3: Regularly remove some of the flower buds on the main branches, so that the flowering time of the side branches grown from the side buds is basically the same as that of the main branches. According to experience, 6-7 flower buds are usually removed;

[0031] Step 4: When side buds appear on the side branches, remove all of them;

[0032] Step 5: Harvest side branches and main branches together when they meet the harvesting standards.

[0033] Experimental group: harvesting started around June 10th, ended on July 3rd, and bulbs were dug on July 30th. Figure 1(a) and (b) show the growth pictures of the plants with side branches in the experimental group. (a) is when the side branches have flower buds when it is close to harvest, and (b) is when the main branches have just appeared flower buds soon after the side branches are left.

[0034] Control group: Harvesting started around June 10th and ended on June 25th, and the bulbs were dug up on July 30th. Figure 1 (c) shows the plant growth picture of the control group.

[0035] Table 1 shows the plant growth conditions of the experimental group and the control group.

[0036] Table 1 Growth of two groups of plants

[0037]

[0038] The following conclusions can be drawn from Table 1:

[0039] (1) The side branch yield-increasing treatment method of the present invention can effectively increase the yield and length of flower branches. Although the flower branches will become thinner than those in the control group (traditional cut flower method), the difference between the two is not significant.

[0040] (2) The method for increasing yield by leaving lateral branches of the present invention can increase the planting area required for a single plant, and can increase the planting spacing according to the normal branch density to save the bulb cost; or maintain the normal planting density and only leave lateral branches for a part of the plants to increase the flower yield per unit area.

[0041] In the present invention, the growth of side branches may cause the main branch to bend, and retaining the opposite side branches has little effect on the main branch. If the main branch still bends significantly, the main branch can be cut off and only two side branches can be retained. Alternatively, the main branch can be removed together without retaining it, because retaining the main branch requires regular removal of flower buds, and there is a certain possibility that it will grow crooked due to the influence of the side branches.

[0042] In the present invention, if two non-opposite lateral buds are retained, the main branch needs to be removed, because the asymmetric growth position of the lateral buds relative to the main branch can easily cause the main branch to bend.

[0043] In the present invention, the side branch fixing method of "fixing the side branch parallel to the main branch" can be replaced by "fixing the side branch obliquely according to the natural growth direction of the side branch", and the natural growth angle of the side branch is maintained, and the side branch is supported by a grid or a vine rope to keep the angle of 45°-60° with the vertical direction. At the same time, when all the side buds are removed, the side branch needs to be lifted up and fixed in the vertical direction again.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
