Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the application.

[0015] The traditional cutting method of Chinese rose has problems of large occupied area, complicated management steps, long maintenance period, underdeveloped root system of cutting seedling and the like. Therefore, the application provides a method capable of effectively improving the survival rate and seedling quality of Chinese rose cutting, so as to realize the high-quality cultivation of Chinese rose cutting seedling.

[0016] The application provides a Chinese rose cutting method, comprising the following steps: placing a cutting container in a constant-temperature culture room; a substrate block is placed in the cutting container, and Chinese rose cutting seedlings are cut on the substrate block; the cutting container is closed, and water is sprayed in the cutting container every 3 days within 15 days after cutting, so that the relative humidity of air in the closed cutting container is above 90%; water is poured on the substrate block in the cutting container every 5 days within 15 days after cutting; and an air valve is arranged on the cutting container. Specifically, the air valve on the cutting container is used to accurately control the humidity, temperature and gas amount (carbon dioxide and oxygen) in the cutting container.

[0017] The cutting container provided by the application comprises a plug tray, a cover and a tray. The plug tray is provided with a plurality of substrate holes, and each substrate hole is provided with a substrate block. Each Chinese rose cutting seedling dipped with rooting powder is cut on the corresponding substrate block. The cover is buckled on the plug tray to form a closed environment. A water-permeable hole is arranged at the bottom of each substrate hole. The inner wall height of the cover satisfies the growth space of the Chinese rose cutting seedling, and an air valve is arranged at the top of the cover. The plug tray is placed on the tray, and the bottom edge of the cover is buckled in the gap between the plug tray and the tray.

[0018] The cutting container provided by the application forms a closed system by adopting a combination of a plug tray and a cover, and the water permeable holes at the bottom of the plug tray are designed to avoid water accumulation in the substrate and prevent the cutting from rotting; the height of the inner wall of the cover is adapted to the growth needs of roses, and the top air valve can be dynamically adjusted (open / closed state), which can maintain high humidity during rooting and can enhance plant resistance by opening the valve to ventilate during seedling raising. The tray is used as a water storage layer in combination with the plug tray to form a three-level structure (tray-plug tray-cover), the tray can accept excess water and slowly infiltrate into the substrate, reducing the need for frequent watering; the cover is designed to ensure closure to prevent water evaporation and external pathogen invasion.

[0019] The application utilizes the cutting container to cultivate roses, which reduces the land occupation area by 60%, increases the water resource utilization rate by 40%, and is convenient to move and manage.

[0020] The method provided by the application places the cutting container with rose cutting seedlings in a constant temperature culture room, and at the same time when the cutting container (provided with an air valve at the top) is in a closed state, sprays water into the cutting container every 3 days within the first 15 days after cutting, so that the cutting container in a closed state maintains a high humidity environment in the constant temperature culture room, thereby effectively avoiding the cutting sprout inhibition phenomenon caused by low humidity; and by watering the substrate block once every 5 days within the last 15 days after cutting, both root rot caused by water accumulation and root growth are prevented. The application uses this method to increase the cutting survival rate from 85% to 98%, significantly shorten the seedling period to 30 days, and reduce the risk of disease and pest infection.

[0021] Further, before cutting the rose cutting seedlings into the substrate block cutting container, the rose cutting is dipped in rooting powder, and then the rose cutting is cut into the substrate block, which is a substrate block that has been poured with water, and finally the cutting container is placed in a constant temperature culture room.

[0022] The method provided by the application effectively promotes the rooting of rose cutting seedlings by dipping in rooting powder, and at the same time, by spraying water into the cutting container every 3 days within the first 15 days after cutting and watering the substrate block once every 5 days within the last 15 days after cutting, the cutting survival rate is effectively improved.

[0023] Figure 1 The cutting process diagram of the cutting method of the application includes: preparation of the substrate block (the substrate block is placed in the plug tray and poured with water), cutting (pruning of the cutting and dipping in rooting powder), the plug tray is placed in the tray, and the cover is placed on the plug tray (the air valve on the cover is in a closed state). Figure 2 The detail view of the air valve on the cover of the cutting method of the application has two states, open and closed, which is convenient for the seedling raising process after the cutting seedlings are rooted. The rose cutting method provided by the application is simple and fast, and can significantly improve the survival rate, axillary bud germination rate and seedling quality of rose cutting seedlings, and shorten the cutting seedling time.

A is a photograph of traditional cutting method (in sunlight greenhouse), B is a photograph of cutting method of the application (in constant temperature culture room). Through comparison of the photographs, it can be found that the traditional cutting method occupies a large area and is complicated to manage, while the cutting method of the application occupies a small area and is convenient and simple to manage.

[0025] Figure 4 It is a comparison chart of growth state of cutting seedlings of traditional cutting method and cutting method of the application. A is a photograph of growth state of cutting seedlings of traditional cutting method, B is a photograph of growth state of cutting seedlings of cutting method of the application. Through comparison of the photographs, it can be found that the overall growth state of cutting seedlings of the cutting method of the application is better. Figure 5 It is a comparison chart of survival rate of cutting seedlings of traditional cutting method and cutting method of the application. It can be seen that the survival rate of cutting seedlings of traditional cutting method is 85%, and the survival rate of cutting seedlings of the cutting method of the application is 98%.

[0026] Figure 6 It is a comparison chart of side view of cutting seedlings of traditional cutting method and cutting method of the application. A is a side view of cutting seedlings of traditional cutting method, B is a side view of cutting seedlings of cutting method of the application. A and B in the chart are photographs of seedlings cut by traditional cutting method and cutting method of the application respectively at the same time. Through comparison, it can be found that the leaves of cutting seedlings of the cutting method of the application are more green, the length of newly sprouted axillary buds is longer, and the growth is more robust.

[0027] Figure 7 It is a chart of growth state of root system of cutting seedlings of traditional cutting method. Figure 8 It is a chart of growth state of root system of cutting seedlings of the cutting method of the application. Through comparison, it can be found that the root system of cutting seedlings cultivated by the cutting method of the application is more robust, the number is more, and the root system is longer.

[0028] Figure 9 It is a comparison chart of root length of cutting seedlings of traditional cutting method. Figure 10 It is a comparison chart of root length of cutting seedlings of the cutting method of the application. *** represents significant difference analysis, and represents p-value≤0.001. As can be seen from the chart, the root length and lateral root number of cutting seedlings cultivated by the cutting method of the application are significantly higher than those of cutting seedlings cultivated by traditional method.

[0029] Further, the size of the tray is 55cm x 28cm x 6cm, and the size of the inner side of the cover is 55cm x 28.5cm x 20cm.

[0030] The application matches the size of the tray (55cm*28cm*6cm) and the cover (55cm*28.5cm*20cm) accurately, ensures that the cover forms a closed space after buckling, prevents the edge from leaking to cause humidity to drop, and the 20cm high inner cavity of the cover provides sufficient longitudinal growth space for the rose cutting, avoids the deformation of the new shoots due to touching the top, and meets the large-scale production demand of 32 plants per tray. Two air valves are arranged on the cover to realize regional regulation, the valve is closed in the early stage to maintain high humidity to promote root growth, and the valve is opened one by one in the later stage of rooting to simulate natural ventilation and gradually reduce humidity to complete the seedling raising. The double-valve design is more flexible than the single-valve, can accurately control the microenvironment in different growth stages, and avoids physiological obstacles caused by environmental mutations.

[0031] Further, the substrate block provided by the application is formed by mixing grass charcoal, vermiculite and perlite, and is wrapped with degradable non-woven fabric on the outside.

[0032] The substrate block provided by the application adopts a golden ratio of grass charcoal (water and fertilizer retention), vermiculite (air permeability and rot prevention) and perlite (drainage and temperature stabilization), and is wrapped with degradable non-woven fabric. The structure not only maintains loose and air-permeable substrate (porosity≥45%), but also releases nutrients through non-woven fabric, prevents substrate from scattering, directly connects the cloth into the soil when transplanting, reduces root damage, and increases survival rate by 15%, and is environmentally friendly and degradable.

[0033] Further, the rose cutting is selected from a stem segment with unbulged axillary buds, and the axillary bud part is avoided when dipping rooting powder, so as to avoid inhibiting bud development.

[0034] The application takes a stem segment with unbulged axillary buds as a cutting, avoids the consumption of stem nutrients by the germinated axillary buds to cause poor root development, and avoids burning the bud points by the liquid medicine when dipping the rooting powder. This method increases the axillary bud germination rate by 25%, increases the length of new shoots by 30%, and makes the root system and the aboveground part grow more evenly, and the quality of the seedling is significantly better than the traditional random cutting method.

[0035] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the application, but not to limit them; although the application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the application.
