Description

Technical Field

[0001] The invention relates to the technical field of plant cultivation, in particular to a camellia sasanqua radicle cutting method. Background Art

[0002] As an important ornamental plant of the genus Camellia in the Theaceae family, Camellia sasanqua has extremely high application value in garden landscape design, potted plant viewing, and ecological greening due to its bright colors, long flowering period, and beautiful tree shape. With the increasing market demand for Camellia sasanqua, how to propagate Camellia efficiently and stably has become the key to the development of the industry. Cutting propagation, as one of the main methods of asexual reproduction, has the characteristics of maintaining the excellent traits of the mother plant and fast reproduction speed. It is an important technical means to achieve large-scale production of Camellia sasanqua.

[0003] At present, the traditional camellia cutting method mainly uses mature branches as cuttings, and reproduces them through simple matrix burial and routine maintenance. However, this method has many limitations: first, the rooting rate of camellia mature branch cuttings is low, usually only reaching 80%-85%, resulting in a reproduction efficiency that is difficult to meet market demand; second, the rooting cycle of cuttings is long, generally requiring 60-90 days, which not only extends the production cycle but also increases management costs; in addition, the root system formed by traditional cuttings is weak, has poor adaptability after transplanting, and is easily affected by environmental changes, resulting in a further reduction in survival rate. These problems have seriously restricted the large-scale breeding and promotion and application of camellia. In order to solve the above problems, scientific researchers have tried to improve the cutting technology by adjusting hormone concentrations, changing matrix ratios, etc., but the results are still not ideal. Some studies have shown that although using conventional auxins to treat mature branches can promote rooting to a certain extent, the improvement in root quality is limited, and excessively high concentrations of hormones can easily cause cuttings to rot. At the same time, traditional substrate ratios are difficult to accurately meet the requirements of air permeability, water retention and nutrient supply during the rooting process of Camellia sasanqua cuttings, resulting in poor root development. In addition, insufficient regulation of environmental factors such as temperature, humidity and light also makes the cuttings susceptible to pests and diseases during the rooting process, further affecting the success rate of reproduction. Therefore, improvements are urgently needed to meet the needs of the rapid development of the Camellia sasanqua industry. Summary of the Invention

Set the environmental temperature range of the seedling container to 25±2℃, the relative humidity to 85%, the daily light time to 8 hours, the light intensity to 4000lx, spray the modified Hoagland nutrient solution once a week to keep the matrix moist. Cuttings began to take root on the 48th day after cutting. The survival rate was 96% after 60 days, the average number of roots was 7.8, the average root length was 4.2 cm, and the seedling height reached 10.2 cm.

[0026] Example 2: In autumn from September to October, healthy and plump camellia sasanqua flowers and fruits were selected, and the camellia sasanqua radicles were collected at the late stage of flower and fruit expansion (the camellia flower shells had not yet cracked). The camellia sasanqua radicle length was controlled to 1.5-3 cm. The camellia sasanqua radicles were sequentially soaked in 75% alcohol for 30 seconds, then disinfected with 0.1% mercuric chloride solution for 5 minutes, and finally rinsed with sterile water 3 times. Subsequently, the camellia sasanqua radicles were immersed in a rooting promoter consisting of 100 mg / L indoleacetic acid (IAA), 50 mg / L indolebutyric acid (IBA), and 50 mg / L naphthaleneacetic acid (NAA) for 2 hours, and a seedling container was prepared. Fill with a mixed matrix consisting of perlite: vermiculite: coconut coir = 1:1:2, adjust the pH value to 6.0, insert the radicle of Camellia sasanqua into the mixed matrix at a depth of 1-1.5 cm, with a plant spacing of 3×3 cm, set the ambient temperature range of the seedling container to 23±2°C, the relative humidity to 80%, the daily light duration of 8 hours, the light intensity of 4000 lx, spray the modified Hoagland nutrient solution once a week to keep the matrix moist.

[0027] Compared with Example 1, it is shown that the method of the present invention also has good applicability in autumn.

[0028] Example 3: In spring, from March to April, healthy and plump camellia flowers and fruits were selected. The camellia radicles were collected at the late stage of flower and fruit expansion (the camellia flower shells had not yet cracked). The camellia radicle length was controlled at 1.5-3 cm. The camellia radicles were soaked in 75% alcohol for 30 seconds, then disinfected with 0.1% mercuric chloride solution for 5 minutes, and finally rinsed with sterile water 3 times. The camellia radicles were then immersed in a rooting promoter consisting of 50 mg / L indolebutyric acid (IBA) and 50 mg / L naphthaleneacetic acid (NAA) for 2 hours. A seedling container was prepared and filled with perlite: vermiculite. A mixed matrix consisting of coconut coir: coconut husk = 1:1:2 was prepared, and the pH value was adjusted to 6.0. The radicles of Camellia sasanqua were inserted into the mixed matrix at a depth of 1-1.5 cm, with a plant spacing of 3×3 cm. The ambient temperature range of the seedling container was set at 25±2°C, a relative humidity of 85%, 8 hours of light per day, and a light intensity of 4000 lx. The modified Hoagland nutrient solution was sprayed once a week to keep the matrix moist. Cuttings began to take root on the 55th day after grafting. The survival rate was 88% on the 60th day, with an average number of roots of 5.6 and an average root length of 3.3 cm. The seedling height reached 8.7 cm.

[0029] Compared with Example 1, it is shown that the rooting promoter composed of 100 mg / L indoleacetic acid (IAA), 50 mg / L indolebutyric acid (IBA), and 50 mg / L naphthaleneacetic acid (NAA) is better than the rooting promoter treatment composed of 50 mg / L indolebutyric acid (IBA) and 50 mg / L naphthaleneacetic acid (NAA).

[0030] Example 4: In spring, from March to April, healthy and plump camellia sasanqua flowers and fruits were selected, and the camellia sasanqua radicles were collected in the late stage of flower and fruit expansion (the camellia flower shells had not yet cracked). The camellia sasanqua radicle length was controlled at 1.5-3 cm. The camellia sasanqua radicles were soaked in 75% alcohol for 30 seconds, then disinfected with 0.1% mercuric chloride solution for 5 minutes, and finally rinsed with sterile water 3 times. The camellia sasanqua radicles were then immersed in a rooting promoter consisting of 100 mg / L indoleacetic acid (IAA) and 50 mg / L indolebutyric acid (IBA) for 2 hours. A seedling container was prepared and filled with perlite: leech. A mixed matrix consisting of stone: coconut coir = 1:1:2 was used, and the pH value was adjusted to 6.0. The radicle of Camellia sasanqua was inserted into the mixed matrix at a depth of 1-1.5 cm, with a plant spacing of 3×3 cm. The ambient temperature range of the seedling container was set at 25±2℃, the relative humidity was 85%, the daily light time was 8 hours, the light intensity was 4000lx, and the modified Hoagland nutrient solution was sprayed once a week to keep the matrix moist. Cuttings began to take root on the 52nd day after cutting. The survival rate was 90% after 60 days, the average number of roots was 6.1, the average root length was 3.6 cm, and the seedling height reached 9.0 cm.

[0031] Compared with Example 1, it is shown that 50 mg / L of naphthaleneacetic acid (NAA) has an irreplaceable effect in promoting the growth of taproots.

[0032] Example 5: In spring, from March to April, healthy and plump camellia sasanqua flowers and fruits were selected, and the camellia sasanqua radicles were collected at the late stage of flower and fruit expansion (the camellia flower shells had not yet cracked). The camellia sasanqua radicle length was controlled to 1.5-3 cm. The camellia sasanqua radicles were sequentially soaked in 75% alcohol for 30 seconds, then disinfected with 0.1% mercuric chloride solution for 5 minutes, and finally rinsed with sterile water 3 times. Subsequently, the camellia sasanqua radicles were immersed in a rooting promoter consisting of 100 mg / L indoleacetic acid (IAA), 50 mg / L indolebutyric acid (IBA), and 50 mg / L naphthaleneacetic acid (NAA) for 2 hours, and a seedling container was prepared. Fill with a mixed matrix consisting of perlite: vermiculite: coconut coir = 1:1:1, adjust the pH value to 6.0, insert the radicle of Camellia sasanqua into the mixed matrix at a depth of 1-1.5 cm, with a plant spacing of 3×3 cm, set the ambient temperature range of the seedling container to 25±2°C, the relative humidity to 85%, the daily light duration of 8 hours, the light intensity of 4000 lx, spray the modified Hoagland nutrient solution once a week to keep the matrix moist. Cuttings began to take root on the 58th day after cutting, and the survival rate was 85% after 60 days, with an average number of roots of 5.2, an average root length of 2.8 cm, and a seedling height of 8.1 cm.

[0033] Compared with Example 1, it is shown that reducing the proportion of coconut bran affects water retention and permeability, which is not conducive to root development.

[0034] Example 6: In spring, from March to April, healthy and plump camellia sasanqua flowers and fruits were selected, and the camellia sasanqua radicles were collected at the late stage of flower and fruit expansion (the camellia flower shells had not yet cracked). The camellia sasanqua radicle length was controlled to 1.5-3 cm. The camellia sasanqua radicles were sequentially soaked in 75% alcohol for 30 seconds, then disinfected with 0.1% mercuric chloride solution for 5 minutes, and finally rinsed with sterile water 3 times. Subsequently, the camellia sasanqua radicles were immersed in a rooting promoter consisting of 100 mg / L indoleacetic acid (IAA), 50 mg / L indolebutyric acid (IBA), and 50 mg / L naphthaleneacetic acid (NAA) for 2 hours, and a seedling container was prepared. Fill with a mixed matrix consisting of perlite: vermiculite: coconut coir = 1:1:3, adjust the pH value to 6.0, insert the radicle of Camellia sasanqua into the mixed matrix at a depth of 1-1.5 cm, with a plant spacing of 3×3 cm, set the ambient temperature range of the seedling container to 25±2°C, the relative humidity to 85%, the daily light duration of 8 hours, the light intensity of 4000 lx, spray the modified Hoagland nutrient solution once a week to keep the matrix moist. Cuttings began to take root on the 56th day after cutting, and the survival rate was 87% after 60 days, with an average number of roots of 5.8, an average root length of 3.1 cm, and a seedling height of 8.4 cm.

[0035] Compared with Example 1, it is shown that although the increase of coconut bran helps to retain water, excessive amount leads to decreased air permeability and affects root extension.

[0036] The data table of Examples 1 to 6, i.e. Table 1, is as follows:

[0037] Comparative Example 1: In spring, from March to April, semi-lignified branches of the current year were selected and cut into 8-10 cm cuttings. The top two leaves were retained, and the base was cut flat. No rooting hormones were used, and the cuttings were directly inserted into sandy soil under conventional management. Results: The survival rate was 80%, the average number of roots was 2.3, the average root length was 1.2 cm, the rooting period was 75 days, and the seedling height was 5.2 cm.

[0038] Comparative Example 2, in which the operation was essentially the same as in Example 1, except that the hormone treatment step was omitted, resulted in a survival rate of 82%, an average number of roots of 3.1, an average root length of 1.8 cm, a rooting period of 68 days, and a seedling height of 6.5 cm. This indicates that hormone treatment significantly promotes root induction.

[0039] Example 1: The radicle was treated with 100 mg / L IAA, 50 mg / L IBA, and 50 mg / L NAA, and the rest of the operations were the same as in Example 1. The results were a survival rate of 96%, an average number of roots of 7.8, an average root length of 4.2 cm, a rooting period of 48 days, and a seedling height of 7.0 cm. This shows that the rooting accelerator composed of 100 mg / L IAA, 50 mg / L IBA, and 50 mg / L NAA can achieve a synergistic effect and significantly improve the survival rate, rooting speed, and root quality of the seedlings.

[0040] The data table of Comparative Examples 1 to 3, i.e., Table 2, is as follows: Comparative Example method Survival rate (%) Average number of roots Average root length (cm) Rooting period (d) Seedling height (cm) Comparative Example 1 Branch cuttings (without hormones) 80 2.3 1.2 75 5.2 Comparative Example 2 Radicle cuttings (without hormone treatment) 82 3.1 1.8 68 6.5 Comparative Example 3 Radicle cuttings (single hormone treatment, only IAA) 85 4.0 2.1 62 7.0 The data table of the best example and the best comparative example, i.e., Table 3, is as follows: index Best embodiment (Example 1) Best comparative example (Comparative example 3) Improvement Survival rate 96% 85% +12.9% Average number of roots Article 7.8 Article 4.0 +95% Average root length 4.2cm 2.1cm +100% Rooting cycle 48 days 62 days -22.6% Seedling height 10.2cm 7.0cm +45.7% By comparing the data of Examples 1 to 6 and Comparative Examples 1 to 3, the advantages of the method are as follows: Significant improvement in survival rate: The highest survival rate under the method of the present application is 96%, which is much higher than the 85% or less of the traditional method, indicating that the method has obvious advantages in the survival mechanism of the radicle; Acceleration of the rooting process: The rooting period of Example 1 is only 48 days, which is nearly 14 days shorter than the traditional method, and the average number of roots reaches 7.8, which is nearly twice that of the traditional method of Comparative Example; Improvement of root quality: The average root length increases to 4.2 cm, which helps the seedlings to quickly establish a stable root system and enhances the resistance and transplant survival rate; Strong adaptability: It can be operated in spring and autumn, and the substrate ratio is flexible, which is suitable for factory seedling promotion; Scientific formula support: The rooting accelerator composed of 100 mg / L IAA, 50 mg / L IBA, and 50 mg / L NAA shows a synergistic effect in inducing rooting, which is better than single or double hormone treatment; Environment-friendly and energy-saving: Renewable substrate (coconut husk) and precise temperature and humidity control system are used to reduce energy consumption and resource waste, which meets the development direction of green agriculture.
