Description

Technical Field

[0001] The invention belongs to the technical field of asexual propagation of Lonicera caerulea, and particularly relates to a Lonicera caerulea cutting seedling bed and a cutting method. Background Art

[0002] Blue honeysuckle is also known as mountain eggplant, black blind fruit, bird-pecking plum, goat milk, etc. It is a perennial deciduous shrub belonging to the genus Lonicera of the family Caprifoliaceae in plant taxonomy. Blue honeysuckle is a new type of small berry resource that integrates edible, medicinal and winemaking processing.

[0003] At present, the main cutting substrates for Lonicera caerulea are: mixed substrates containing peat soil and garden soil, and inorganic substrates mainly composed of river sand and perlite. The mixed substrate mainly composed of peat soil and garden soil is prone to weeds, and it is easy to touch the root system during the weeding process, resulting in the rooting rate and survival rate of the cuttings being only about 80%, and manual weeding is required in the later stage, which is costly. River sand and perlite are inorganic substrates with strong air permeability, not easy to grow weeds, and low labor costs. They are also suitable for the root development after the cuttings take root, but they have the following disadvantages: because there are no nutrients, the required nutrients cannot be provided after the cuttings take root, resulting in a lower survival rate, thereby affecting the growth of the root system and the aboveground part. Therefore, after the root system of the cutting seedlings reaches a certain degree of lignification, it must be immediately transferred to the bed for management, and the seedlings will easily die during the transfer process.

[0004] The prior art simply mixes mixed substrate and river sand as cutting substrate, but there are still problems of low rooting rate and survival rate. Summary of the invention

[0005] The invention aims to provide a caerulea honeysuckle cutting seedling bed and a cutting method, which solve the problems of low rooting rate and survival rate after caerulea honeysuckle cutting in the prior art.

[0011] Preferably, the plant rooting agent is Genbao No. 3 stock solution or ABT No. 1 rooting powder solution; the concentration of the ABT No. 1 rooting powder solution is 100 mg / L to 200 mg / L.

[0012] The method of spraying water regularly after the blue honeysuckle is cuttage comprises the following steps: spraying water once at 11 o'clock in the morning from the first to the fifteenth day after the blue honeysuckle is cuttage, each spraying time is 2 minutes to 3 minutes, and the water speed is 0.039 L / s; spraying water once at 10 o'clock in the morning and 2 o'clock in the afternoon from the sixteenth to the thirtieth day after the blue honeysuckle is cuttage, each spraying time is 2 minutes to 3 minutes, and the water speed is 0.039 L / s; spraying water three times a day after the blue honeysuckle is cuttage for one month, divided into Especially at 10 a.m., 12 noon and 2 p.m., each time spraying for 2 to 3 minutes, the water rate is 0.039L / s; two months after the blue indigo honeysuckle cuttings, start spraying water from 8 a.m. every day, spray once every two hours until 6 p.m., a total of 6 times of water, each spraying time is 2 to 3 minutes, the water rate is 0.039L / s; 5 months after the blue indigo honeysuckle cuttings, spray once during the day, the spraying time is 1 to 2 minutes, the water rate is 0.039L / s.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 The present invention is a schematic diagram of the substrate laying of the Lonicera caerulea cutting seedling bed described in Example 1 and Example 2. DETAILED DESCRIPTION

[0017] The present invention is further described below by specific examples, but the scope of the present invention is not limited thereto. The details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications or replacements all fall within the protection scope of the present invention.

[0018] The inventive concept of the present invention is as follows: The present invention provides a blue honeysuckle cutting seedling bed, which consists of a surface layer and a base layer, the surface layer is laid on the base layer, the surface layer has a height of 4 cm to 5 cm, and the base layer has a height of 15 cm to 16 cm; the laying matrix of the surface layer is river sand, and the laying matrix of the base layer is a mixed matrix; the particle size of the river sand is 0.35 mm to 0.5 mm; the mixed matrix is ​​composed of garden soil and peat soil, and the weight ratio of the garden soil to the peat soil is 1:1 to 1.2.

[0019] Because river sand has good water permeability and air permeability, placing it on the surface layer is conducive to the root system of blue honeysuckle cuttings taking root downward. When the blue honeysuckle cuttings are inserted into the blue honeysuckle cutting seedbed, because the surface layer is shallow, the roots of the cuttings can pass through the surface layer after a short period of growth to contact the mixed matrix containing peat soil and garden soil in the basal layer, which can provide nutrients for the blue honeysuckle cuttings and promote rooting and survival of the cuttings. At the same time, because the mixed matrix providing nutrients is located in the basal layer, and the river sand on the surface layer cannot provide nutrients, it is not easy to grow weeds on the surface of the blue honeysuckle cuttings seedbed. There are no weeds and blue honeysuckle cuttings competing for nutrients, water, sunlight, etc., which further improves the rooting rate and survival rate of the blue honeysuckle cuttings. In addition, the labor cost of weeding is also saved.

[0020] The inventors found that a mixed matrix was laid on the surface layer of the seedbed and river sand was laid on the base layer. Because the mixed matrix was rich in nutrients, weeds were extremely easy to grow on the surface of the seedbed, which not only increased the weeding cost, but also easily touched the roots of the blue indigo honeysuckle cuttings during the weeding process, causing the death of the blue indigo honeysuckle cuttings; and when the surviving blue indigo honeysuckle cuttings passed through the surface layer and took root into the base layer, the river sand could not meet the nutrients required by the blue indigo honeysuckle cuttings, which would further lead to the death of the blue indigo honeysuckle cuttings.

[0021] The existing technology simply mixes mixed matrix and river sand as cutting medium, but there are still problems with rooting rate and survival rate.

[0022] In summary, laying a mixed matrix containing garden soil and peat soil under the river sand can not only provide the nutrients and water required for the rooting and germination of the blue indigo honeysuckle cuttings, ensure the rooting rate and survival rate of the blue indigo honeysuckle cuttings, but also reduce material costs and later field management costs.

[0023] Although the prior art 202011382539.X also has a scheme for a substrate seedbed for cuttings of blue honeysuckle, its base layer is paved with a mixture of river sand, larch needles, sawdust and garden soil, and the surface layer is paved with a mixture of larch needles and sawdust. Compared with this, the present invention uses fewer types of raw materials for laying the substrate, and is easier to obtain and has lower costs. At the same time, the seedbed preparation process of the present invention is simpler. On this basis, the rooting rate and survival rate of blue honeysuckle cuttings do not decrease significantly.

[0024] The main cutting methods of honeysuckle are spring hardwood cuttings and summer softwood cuttings. In spring hardwood cuttings, when cutting cuttings, it is combined with spring pruning. The cutting time is earlier, and the thinned branches can be reused. In summer softwood cuttings, cutting cuttings are cut in summer, that is, in the growing season, and it is not easy to grasp the degree of lignification of the cuttings and the size of the leaves to be retained; at the same time, the temperature is high, and it is difficult to control the temperature and humidity of the seedbed and the air. High temperature and high humidity are prone to occur, resulting in infection and rotten seedlings, or insufficient air humidity causing the cuttings to evaporate and die; there is also a disadvantage that the cutting time is late, the growth of the seedlings is small in the same year, and they cannot be planted in the same year.

[0025] The present invention also provides a method for cutting of Lonicera caerulea, that is, when thinning Lonicera caerulea cuttings in spring, sterilize and disinfect the thinned Lonicera caerulea cuttings, dip them in a plant rooting agent, and cut them into the Lonicera caerulea cutting seedling bed of the present invention, spray them with water, sterilize and disinfect them, and cultivate and manage them. The cutting depth is the same as or slightly shallower than the depth of the substrate surface layer. The cutting depth is designed so that the root system can directly grow to the substrate base layer after the cuttings take root, so that they can obtain sufficient nutrients and water, and improve the survival rate and growth amount.

[0026] In order to enable those skilled in the art to better understand and implement the technical solution of the present invention, the present invention is further described below in conjunction with specific embodiments and drawings.

[0027] In the description of the present invention, unless otherwise specified, all reagents used are commercially available and all methods used are conventional techniques in the art.

[0101] 2. Seedbed preparation

[0102] Before the cuttings of Lonicera caerulea, the Lonicera caerulea cuttings seedling bed described in Comparative Example 1 was placed in a plastic greenhouse and sterilized with a bactericidal disinfectant.

[0103] 3. Cuttings collection and processing

[0104] In spring, before the buds of the blue honeysuckle sprout, collect one-year-old branches that are strong, have full buds, and are free of pests and diseases as cuttings. The cuttings are 5 cm long, with a pair of buds left on the top; every 100 plants are bundled into a bundle and sterilized with a bactericidal disinfectant.

[0105] 4. Cutting method

[0106] The time for cuttings of blue indigo honeysuckle is spring, that is, late March and early April. On the day of cuttings, water the blue indigo honeysuckle cuttings seedling bed sufficiently. Before cuttings of blue indigo honeysuckle, use a hole puncher slightly thicker than the blue indigo honeysuckle cuttings to make holes in the blue indigo honeysuckle cuttings seedling bed as guide eyes. The diameter of the blue indigo honeysuckle cuttings is about 0.4 cm, the diameter of the guide eyes is 0.6 cm, the depth of the guide eyes is 4 cm, and the plant spacing determined by the guide eyes is 5 cm × 5 cm. When cuttings of blue indigo honeysuckle, choose Genbao No. 3 plant rooting agent, dip the original medicine for 13 seconds, the cutting depth is 4 cm, and water thoroughly after cutting.
