The formation layer of summer cuttings is active, and it is easy to heal under the conditions of high temperature and high humidity, and can greatly shorten the rooting time, and the survival rate of cuttings is high. Such as sweet-scented osmanthus, camellia, purple magnolia, smiling, woody, etc., summer cuttings than spring, autumn and winter three seasons cuttings survival rate is much higher, rooting time is only about 10 days, only one-third of spring insertion time It is worthwhile to save manpower and material resources. First, suitable for the type of plug suitable for summer flowering cuttings of the two major categories of flowers, one is the hard branch cutting is not easy to root or slow rooting species, such as sweet-scented osmanthus, clove, purple magnolia, holly, smile, paste stem jellyfish, thorn Tung, coral trees, Belgian azaleas, rubber trees, metasequoia, Chigi, and falling cedar; other species are more likely to take root, such as boxwood, firethorn, rose, Admiralty, spring, June snow, pomegranate, Muddy, Jasmine, Dragon-tobacco, Five-colored plum, Chinese wolfberry, bougainvillea, bergamot, Podocarpus, Nantianzhu, hibiscus, zhujiao, changye, Jinsiliu, crape myrtle, Jinhuahua, poinsettia, hydrangea, octagonal gold Pan, Ling Xiao, Hong Bei Gui and so on. Second, the plug-in requirements should be selected to intervene in the wind, shade, drainage, irrigation, no West position. The soil should be free from pest and disease, and the matrix type can be selected according to the different types of flowers. Such as camellia, sweet-scented osmanthus, smile, rose, etc. to garden soil is appropriate; boxwood, Phnom Penh, privet, ground brocade, oleander, hibiscus, Euonymus fortunei, etc., then sandy soil is better; gardenia, lobular wolfberry fruit to vegetarian The sand was used as a matrix cutting; Fusang, bougainvillea, etc. were based on humus. The slot should be made into a turtle shape to prevent water accumulation. Third, the cutting method Select the semi-woody branches from June to July, cut a small section of about 10 cm. The cuttings should be topped with buds, and the lower blades should be cut. The leaves of the lobule retain the upper 6 to 8 leaves, such as Cyclovirobuxine, Pyracantha fortunei, Euonymus fortunei, and pomegranate. The large leaf cuttings only retained the top two or three leaves, such as camellia, sweet-scented osmanthus, hibiscus, smiling, jasmine, and liriodendron. Others such as Chinese rose, Admiralty, and Ling Xiao can leave no leaves to reduce transpiration. Types of roots that are not easy to root, such as camellia, osmanthus, and smiling, etc., can be soaked with rooting powder or 500 ppm of naphthalene acetic acid for 5 to 10 minutes, which can greatly increase the survival rate of cuttings. Before plugging, firstly insert the cutting bed into a water permeable layer, and then insert the prepared cuttings into the soil with a spacing of 510 cm. The depth of the cutting is about half the length of the ear. Only a few leaves are left outside the soil, the base is compacted, and finally the water is poured. Once permeable. The bamboo arches on both sides of the slotting machine cover the membrane to moisturize, and the double shade shading shed can significantly increase the survival rate of cuttings and shorten the rooting time. Fourth, post-insertion management is mainly to control humidity and light. The optimum temperature for cutting rooting is 15°C to 22°C and the relative humidity is maintained at 80% to 90%. Frequent leaf spraying and slotting irrigation are performed to keep the surface of the bed moist and reduce the temperature of the bed. If the temperature of the bed surface exceeds 30°C, the film at both ends of the slotted bed will be lifted before and after noon, and the ventilation and air-flow will be sprayed to achieve The purpose of humidification and cooling. After about 30 to 45 days, most of the cuttings can grow a good root system. At this time, appropriate watering should be reduced and appropriate amount of thin liquid fertilizer should be applied to accelerate the growth of cuttings.
