First, seed propagation General flower seeds, such as Begonia, Impatiens and other seeds, without any treatment, you can direct sowing, and seed shell with wax, such as ash, magnolia and other available water in order to broadcast the seed mix into a paste, lotus, Canna hard seed coat before sowing the seed coat to be bruised, soaked with warm water 24 hours after sowing. Flowering plum seeds, such as spring planting, spring is able to germinate. Before sowing of the seed germination test is required to test the germination rate, in order to determine seeding rate. For the seed coat thick woody flowers, are generally required for germination before sowing in order to achieve fast and neat emergence, seedling rate purposes. Multi-germination flooding, stratification and other laws. 1, flooding germination method. Can be divided into three kinds of water treatment. First, the cold water soaking germination, water temperature above 0 ℃ for thin-shell species of seeds, such as wisteria, palm, bloom, cedar, etc.; second warm water soaking germination, water temperature 40-60 ℃, suitable for thicker types of shell peony , peony, Bauhinia, maple, Sophora japonica, cedar, larch, etc.; Third hot water soaking germination, water temperature 70-90 ℃, hard seed coat for seed, such as acacia, acacia, camphor tree. Amount of water when soaking the seeds three times into the water when mixing, so that the seed is heated evenly. When soaking with hot water until the water temperature down to the natural temperature, that is, stop stirring, and then soak 1-3 days until the seeds absorb the expansion, remove germination at 18-25 ℃ temperature. Germination during the washing with warm water 1-2 times a day, and pay attention to gently turning, until the seeds can be planted after a broken mouth. 2, laminated germination method. Germination is laminated with three copies of wet sand and 1 part seed mixture on the insulation 0-7 ℃ cold temperature conditions. This method is suitable for Magnolia grandiflora, Michelia, Magnolia, Caprifoliaceae, and flowers the following year in order to germinate seeds. In addition, long-term dormancy of seeds or seed sprouting the next year, such as laurel, holly, coral trees, also with variable-temperature germination method, that is, the day after soaking to maintain 25-30 ℃, the night temperature is about 15 ℃, repeated about 10 -20 days, you can achieve germination.
Second, the split propagation Isolated from the mother plant on small plants or isolated from the mother bulbs, bulbs, plants be planted into a separate new breed called cut. This method is divided into two types of ramets and the ball. 1, the branch method. The mother plant roots took place on the tiller, tillers and roots such as split, developed into an independent new branch. Ramets flower species breeding period determined by the general renovation of the spring flowering season in ramets; autumn flowering ramets in the spring. Ramets need to shoot the fall to sleep, underground still active periods, such as peony, etc.; ramets should germinate in the spring before, such as Hosta, Iris, etc. Ramets, the perennial flowers, remove the roots attached to the first places in soil, and then use a knife according to according to the nature or gap, to be bound to it, leaving the cut after the first small plants with at least 2-3 buds . Flowers like the mother plant ramets do not need to knock when you went, took shovels to soil can be dug, dug sprout from the side of the rhizosphere can be planted. When ramets less root injury, to facilitate survival. 2-point method. Bulbs, flowers Reproduction orientin ball using this method. The ball time after hibernation, the bulbs, bulbs dug from the split on the cue ball, developed into an independent new plants, small bulbs such as hyacinth, generally occurs at the base of 4 weeks, after the separation from the foster mother of the ball can reach 4 years with the same mother plant size; Narcissus ball after three years can grow into big balls, big balls tulip form generated by the year 2-3 small ball, small ball after 1-2 years of growth can grow into big balls. Gladiolus ball can be formed by the 1-year growth of 1-4 large balls, and output of many small balls.
Third, the grafting method. Grafting is the need to plant flowers artificial plants, branches or buds grafted on another flower on a plant stem or root. Grafting and budding Zhijie into two categories. This method not only to maintain the original species characteristics, but also increase the resistance to adverse environmental conditions, and can adjust the flowers of the growth process is conducive to early fruition. This method is used for woody flowers, vegetation, flowers can also use this method a few. Grafting the key to survival, one master of grafting period, should generally be in the sap begins to flow when the buds have not yet germinated, Zhijie more in the early spring from March to April, more than in July and August budding; second scion and rootstock to Select the close genetic relationship with the plant affinity, as in the same family of plants of privet as a rootstock, grafted sweet-scented osmanthus, or cloves; third is the growth of the rootstock should select a strong 2012 annual seedlings or cuttings, if the rootstock age bias old, it will affect survival. Scion varieties should be chosen good, robust mature year-old branches; Fourth, pay attention to the first cut when the grafted rootstock scion after the cut (reducing evaporation time), tools to be sharp, the incision should be smooth, grafted layer was formed to align, thin-walled cells to closely aligns joints to seal, tie tie elastic to moderate; fifth time after grafting to check on the live plants have been received, should be lifted in tie tied things, if grafting method when using bulldozers, saw new shoots sprouting immediately remove the mound, so as not to see the sun and yellow shoots for.
