Forsythia is a woody deciduous shrub. The flowers were opened in the early spring. The long and short branches were splendid and flowery. They were golden flowers and were good cut flowers. They were also widely used as garden plants. Its branch chief grows or hangs down. The branches and branches of the crane are hollow. The single leaves are opposite, the leaves are ovate and oval, and some of the leaves are deep-divided into three leaflets. The flowers are yellow, the bell-shaped corolla is 4 deep and the flowering period is 3-. April. Forsythia suspensa, deciduous shrub, is a genus of Forsythia genus, with antibacterial, anti-inflammatory, antipyretic, antiemetic, diuretic, anti-liver damage and analgesic effects. Forsythia native to China's central and western provinces, warm and humid, sunny, warm and humid environment, cold and drought-resistant, afraid of water spots, strong germination, resistance to pruning, strict requirements on the soil. Forsythia breeding sowing, cutting, layering, ramets and other methods are easy to succeed. In March, hard branches are about 20 cm long, and they are placed on a bed or bed to keep them moist. On the growing season, tender branches are also recommended. The propagation of the ramets is carried out after defoliation. Spring ramets will affect the amount of flowering that year. Batten propagation is carried out according to conventional methods, and the pendulous cutting injury can be pressed into the soil. Forsythia flowers are often born on one-year branches, so each year after flowering, old branches and annual branches need to be re-cut to promote new shoots. New shoots growing vigorously can be cut short once in the early summer. When the land is planted, there is no need for additional management. A base boat is applied in the winter and it is pruned after the flowering. Potted plants should be made of fertile soil. After flowering, they should be cut and heavy, and the fertilizer must be applied 1-2 times a month. Watering at the right time should keep the soil moist and not too dry. Also give good light. Forsythia flowers are easy to succeed. On the Spring Festival or 20 days before New Year's Day, it will be moved into the greenhouse for warming, and then it will bloom. The same commonly cultivated Admiralty flower is very similar to the forsythia. It is native to Zhejiang, Fujian and other places and is widely cultivated in East China. The flowers were germinating and bridled green, and the stem sections asked for radium to be flaky without three leaflets. This can be distinguished from forsythia. First, the characteristics of Forsythia up to 3 meters, branches or sagging, twigs slightly 4-angle, hollow internodes, there are obvious lenticels. Leaves simple or lobulated into 3 leaflets, leaf blade ovate, margin irregularly serrate, surface green, semileafy. Flowers open first, several to several, axillary, yellow. Capsule, narrowly ovate, slightly obscure, apex pointed like beak, split when split. Seeds narrowly elliptic, brown, with thin wings on one side. Flowering period March-April, fruit ripening period 8-10 months. Forsythia is cold, drought-tolerant, and barren-resistant. It does not require a lot of climate and soil quality, and has a wide range of habitats. In the dry slopes or in the soil, even the bedrock or the weathering parent material of the purple sand shale can grow. Forsythia root system is developed, although the main root is not significant, but its lateral roots are relatively thick and long, many fibrous roots, extensive extension around the main root, greatly enhancing the ability to absorb nutrients and soil. Forsythia hardy strong, after the cold-resistant exercise, can withstand -50 °C low temperature, its amazing cold resistance, making it a leader in northern landscape. Forsythia germinates strongly and grows quickly, and its distribution can be quickly expanded. Second, cultivation techniques 1. Selection of soil preparation and fertilization. For artificially cultivated Forsythia, sunlight, loose soil, fertile soil, high humus content, and leeward and sandy soil land should be selected for planting. Mushi Fertilizer 2000 kg. The use of large ridge bed technology, bed width 130-140 cm, length as required, bed height 10-12 cm, bed spacing 30 cm. 2. Breeding technology. Forsythia is easier to survive, and its cultivation and management techniques are simple. It is possible to sow seedlings, as well as cuttings, ramets, and infusions. (1) Seed breeding. The seeds were sown in mid-to-late May. About half a month later, the seedling height was 7-10 cm. The first time the seedlings were seeded, and some of the dense seedlings were removed. When the seedling height was 13-17 centimeters, the seedlings were transferred twice every second. 7-10 cm left 1 seedling, after the timely cultivation of weeding, top dressing and other management. For a year of cultivation, if the seedling height is more than 33 cm, it can be planted. (2) Breeding. After defoliating in winter and before sprouting in early spring, part of the seedlings that can be excavated from the mother plant can be planted, and soil can be cultivated at the foot of the mother plant to promote more long roots of the seedlings, which is conducive to survival after planting. (3) Batten propagation. In the spring, the drooping shoots were pressed into the soil, and the young plants were planted in spring. (4) Cut propagation. Select 1-2 years of strong twigs, cut into 30-40 cm long cuttings. In the late spring of April, in a well-made bed, according to the requirements of the base planting, spacing is 50 centimeters, plant spacing is 40 centimeters, a seedling is planted in each hole, the cover soil is compacted, the rooting water is poured, and the cover soil is slightly higher than the ground. It is earth-stacked. 3. Field management. (1) Weeding and weeding. Every winter, weeding and weeding should be done next to the forsythia trees. The weeds around the plants can be eradicated or removed by hand. (2) Fertilization. Appropriate amount of top-dressing compost and manure fertilizer were applied after the ditch was planted next to the plants. (3) Drainage and irrigation. Pay attention to keeping the soil moist, watering the drought in time, and draining the trenches during the rainy season so as to avoid water rot.
