[0034] Since Daphniphyllum glaucescens prefers relatively dry soil in winter, as an implementation method, taking the cutting site in Qingyuan District, Ji'an City, Jiangxi Province as an example, the watering amount is reduced after December of the solar calendar in this area, and other areas implement with reference to the climate in Qingyuan District, Ji'an City, Jiangxi Province.

[0035] As an implementation method, germination can be observed 10 days after the cutting is completed, and it is basically completely germinated in 20 days. If the number of germinated plants in the initial stage of cutting is less than 50% of the total number of cuttings, the watering amount can be reduced according to the water content of the substrate.

[0043] To further illustrate the present invention, the following describes in detail the application of a cutting product provided by the present invention in the cutting seedling raising of Clerodendrum cyrtophyllum Turcz. and the method for efficient cutting seedling raising in conjunction with embodiments, but they cannot be understood as limiting the protection scope of the present invention.

[0044] Example 1

[0045] The cutting site is located in Qingyuan District, Ji'an City, Jiangxi Province, with its geographical location between 25°58′32″ and 27°57′50″ north latitude and between 113°46′ and 115°56′ east longitude, belonging to the subtropical monsoon climate.

[0046] The steps are as follows:

[0047] I. Collection of Clerodendrum cyrtophyllum Turcz. and preparation of cuttings

[0048] In late October of the solar calendar, the current-year germinated branches of Clerodendrum cyrtophyllum Turcz. are collected, and semi-lignified branches of 2- to 3-year-old Clerodendrum cyrtophyllum Turcz. plants with good growth conditions, strong growth in the middle of the tree body, plump lateral buds, and no pests and diseases are selected. After collection, the branches are pruned to remove redundant branches and leaves, and only two bud primordia are retained. The cuttings are of the same thickness and length, with a diameter of 0.6 to 0.8 cm and a length of 12 to 15 cm. The upper end of the cutting is cut flat, and the lower end is cut obliquely at an angle of 45°. The incision is 1 cm away from the bud primordium.

[0049] II. Pretreatment of cuttings and preparation of substrate

[0050] Bundle 30 cuttings trimmed on the same day, soak the base in 800-fold solution of carbendazim wettable powder with a mass fraction of 80% for 1 minute for disinfection, and then prepare a solution of ABT No. 1 rooting powder with a concentration of 400 mg / L, and soak the base of the cuttings in the solution for 2 hours. The substrate is a mixture of peat soil and perlite, and the mass ratio of the two is 1:1. To ensure the substrate is sterile, first spray and disinfect it with 0.1% potassium permanganate solution and dry it for 2 days. Then, thoroughly irrigate the substrate with a carbendazim solution with a concentration of 1 g / L. After the cuttings are soaked, they can be cut.

[0051] III. Cutting operation and post-cutting management

[0052] Insert the processed cuttings into the disinfected and dried substrate, and spray an appropriate amount of clean water. Then, gently compact the substrate around the cuttings by hand. After cutting, immediately soak the substrate thoroughly by the permeable method.

[0053] During the post-cutting management process, water twice every 7 days in the initial cutting stage (i.e., within 30 days), and irrigate a 5% solution of a general plant nutrient solution on the 15th day. Germination can be observed on the 10th day after cutting, and germination is basically complete on the 20th day. If the number of germinations in the initial stage is small, the amount of watering can be reduced according to the water content of the substrate. Pay attention to removing weeds in time. The amount of watering needs to be reduced after December in the Gregorian calendar, and the nutrient solution can be applied once every 45 days.

[0054] IV. Transplant at the right time

[0055] In early January of the second year in the Gregorian calendar, the surviving plants can be transplanted. When transplanting, if the seedlings are too tender and long, part of the top tender stems can be cut off, leaving the seedling height about 30 cm. If the main root is too long, the root tip part should be cut off. Then, stand one seedling in the center of each planting hole and straighten the roots, keeping the roots stretched. After filling the soil to 50% of the planting hole, gently lift the seedling and compact the soil, then fill the soil to the same level as the ridge surface and compact it, and then cover it with a layer of perlite about 1.5 cm thick. The planting depth should be about 1 cm deeper than the original seedbed rhizosphere.

[0056] In this example, under the conditions of an ABT No. 1 concentration of 450 mg / L and a substrate composed of perlite and peat with a mass ratio of 1:1, the germination rate of the cuttings can reach 93.67%, and the survival rate of the seedlings after transplantation is also as high as 85%, subverting the previous understanding that the survival rate of Jasminum lanceolarium cuttings is only 20%. Therefore, the high survival rate of seedlings and short breeding period in this example enable cuttings to quickly meet the huge market demand and generate economic benefits.

[0057] Comparative example 1

[0058] Collect natural wild Jasminum lanceolarium seedlings on the mountain for centralized planting.

[0059] This breeding method is difficult to meet the needs of large - area planting due to limited seedling resources and cannot be promoted.

[0060] Comparative Example 2

[0061] Seed sowing and seedling raising

[0062] In autumn, collect the mature fruits of Clerodendrum cyrtophyllum Turcz. from the plants and process them to dry in the sun. Then, conduct double plowing during winter when building the seedbed. After fertilization, sow in March - April in spring. Subsequently, top - dress with commercial organic fertilizer 2 - 3 times until maturity in October, and transplanting can be carried out from November to March of the following year.

[0063] This breeding method is seed breeding. Since Clerodendrum cyrtophyllum Turcz. blooms and bears fruit relatively slowly, it takes up to 1 year from seed treatment to seedling transplanting, which is significantly longer than the cutting seedling raising of the present invention in Example 1. And due to problems such as ineffective seed screening and low seed germination rate, the quality of seedlings is prone to be uneven, and the quality of seedlings is low, which in turn affects the survival rate of seedlings and the growth and yield of later crops.

[0064] Example 2

[0065] Same as Example 1, the cutting site is located in Qingyuan District, Ji'an City, Jiangxi Province, with the geographical location between 25°58′32″ - 27°57′50″ north latitude and 113°46′ - 115°56′ east longitude, belonging to the subtropical monsoon climate.

[0066] Collect the current year's germinated branches of Clerodendrum cyrtophyllum Turcz. in late October of the solar calendar, and select 2 - to 3 - year - old Clerodendrum cyrtophyllum Turcz. plants with good growth conditions. After collection, prepare the cuttings in the same way as in Example 1.

[0067] Bundle 30 cuttings trimmed on the same day into one bundle, soak the base in 800 - fold solution of carbendazim wettable powder with a mass fraction of 80% for 1 min for disinfection, then prepare a solution of ABT No. 1 rooting powder with a concentration of 400 mg / L, and soak the base of the cuttings in the solution for 2 h. The substrate is also selected as a mixture of peat soil and perlite, with a mass ratio of 1:1, and disinfected. After completing the cutting operation, continuously carry out post - cutting management such as watering, and transplant the surviving plants in early January of the following year in the solar calendar.

[0068] In this example, under the conditions of ABT No. 1 concentration of 400 mg / L and a substrate composed of perlite and peat with a mass ratio of 1:1, the germination rate of cuttings can reach 86.67%, and the seedling survival rate after transplantation is also as high as 85%. Therefore, this example also has a high germination rate and seedling survival rate, which can ensure the growth of Clerodendrum cyrtophyllum Turcz. seedlings and generate economic benefits.

[0069] Comparative Example 3

[0070] Based on the cutting site in Example 1 and the same pretreatment of cuttings, cutting operations, etc., only change the substrate to a substrate composed of peat soil, perlite, and vermiculite, with a mass ratio of peat soil, perlite, and vermiculite of 1:1:1. The remaining steps are the same as those in Example 1. Use the current-year germinated branches of Daphniphyllum macropodum in late October of the solar calendar for cutting treatment and transplant in a timely manner.

[0071] Under this substrate ratio, the germination time is significantly longer than that of the cutting seedlings in Example 1. The Daphniphyllum macropodum cultivated in Comparative Example 3 germinates 8 days later than the Daphniphyllum macropodum cultivated in Example 1; moreover, the germination rate and the survival rate after transplantation of the Daphniphyllum macropodum cultivated in Comparative Example 3 are both less than 70%, which is significantly lower than that in Example 1, thus affecting the subsequent growth of Daphniphyllum macropodum seedlings and the economic benefits are lower than expected.

[0072] Comparative Example 4

[0073] Based on the cutting site in Example 1 and the same substrate ratio, cutting operations, etc., only change the proportion concentration of rooting agent ABT No. 1 to 300 mg / L. Under the same other cutting conditions, use the same batch of Daphniphyllum macropodum branches for cutting and transplant after cultivating for a period of time.

[0074] In terms of the germination rate, 53.33% of the cuttings germinate under the condition of 300 mg / L, which is significantly lower than the 93.67% germination rate in Example 1. Moreover, in terms of the seedling formation rate, the seedling formation rate of Comparative Example 4 is 43.67%, which is significantly lower than the seedling raising result in Example 1, and the quality of the seedlings is difficult to guarantee.

[0075] Comparative Example 5

[0076] Based on the cutting site in Example 1 and the same substrate ratio, cutting operations, etc., only change the proportion concentration of rooting agent ABT No. 1 to 500 mg / L. Under the same other cutting conditions, use the same batch of Daphniphyllum macropodum branches for cutting and transplant after cultivating for a period of time.

[0077] In terms of the germination rate, under the treatment of 500 mg / L rooting agent, the germination rate is only 26.67%, which is far lower than that in Example 1; moreover, the seedling formation rate of Comparative Example 5 is less than 30%, which is significantly lower than the seedling raising result in Example 1, and the growth and yield of the later crops are not sufficient to meet the market demand.

[0078] In summary, using the high-efficiency cutting seedling raising method of Daphniphyllum macropodum in the embodiments of the present invention can not only maintain the excellent characteristics of the parent, but also greatly shorten the breeding cycle. And under the treatment of ABT No. 1 rooting powder solution with appropriate concentration and the substrate, the survival rate can be stabilized at about 90%, and the seedling formation rate can be stabilized above 75%.

[0079] Although the above embodiments have described the present invention in detail, they are only a part of the embodiments of the present invention, rather than all of them. People can also obtain other embodiments based on this embodiment without creative efforts, and these embodiments all fall within the protection scope of the present invention.
