Spring jasmine pictures
As the earliest ornamental shrub to bloom in early spring, winter jasmine is favored by gardening enthusiasts for its bright color and tenacious vitality. Its branches have the characteristics of falling like waterfalls, which can be planted in the courtyard or made into bonsai. This paper systematically combs its biological characteristics and key points of cultivation techniques. Typical biological characteristics of Jasminum mollissima leaves and branches characteristics The branches are slender and drooping in four prisms, and the new branches are greenish green. Compound leaves consist of 3-5 small leaves. The single leaf is long oval or elliptical, and the leaf is 0.8- 3 cm long. The waxy layer on the leaf surface can reduce water evaporation. In winter, some varieties will show red-brown markings. Flower morphology and structure The first leaves open from February to March in early spring, with a flower diameter of about 2 cm. The corolla is plate-shaped with high feet, and the base is combined into a tube shape and the upper part is split into 5-6 petals. The stamens are inserted in the middle of the corolla tube, the pistil stigma is bifid, the calyx has 5-6 lanceolate lobes, and the flowers have a faint fragrance. The optimal growth temperature range of environmental control factors in scientific maintenance operation specifications is 12-25℃, and maintaining 15℃ in spring can prolong the flowering period. In summer, sunshade nets are needed to block out the strong noon light. In winter, in northern areas, rootstock soil and cold-proof measures are needed, and potted plants should be moved indoors above 5℃ to winter. The water and fertilizer management cycle follows the watering principle of "two more and one less": keep the soil moist during the flower bud differentiation period (October) and post-flowering recovery period (April), and moderately control water during the full flowering period. Diluted soybean cake fertilizer is applied every half of the month during the growth period, and potassium dihydrogen phosphate is added in August to promote lignification of branches. Shaping and pruning techniques Carry out shaping and pruning immediately after flowering, retaining 2-3 bud points to cut off the branches. The old piles need to be retracted and renewed every 2-3 years. Combined with aluminum wire coil binding, it can create bonsai shapes such as cliff style and waterside style. After pruning, healing agents need to be applied to the wounds.
After mastering scientific maintenance methods, the jasmine can bloom continuously for more than 20 years. This plant, which has both ornamental value and ecological adaptability, can not only decorate early spring garden landscapes, but also be an important specimen material for studying Oleaceae plants.
