Cultivation techniques of Forsythia suspensa seed breeding should choose sandy loam or loam soil with shelter from the wind and sun, good drainage, deep soil layer, loose and fertile sandy loam or loam, and add rotten chicken and sheep manure 1000kg, calcium superphosphate 50kg, diammonium phosphate 30kg, deep ploughing fine rake to make a high bed with wide 100~120cm, high 20~30cm and 5m long; cuttings should choose sandy land with convenient irrigation and good permeability; planting should choose gentle slope land facing the wind. The cultivation is mainly by sowing and raising seedlings, and it can also be propagated by cutting. The seeds can be collected all the year round, and the seeds are drenched in wet water for about 1 week after harvest. When the pericarp turns black and rotten, the seeds are rubbed in the water in the basket and bleached to get the seeds. The seed emergence rate of the fruit is about 16%, and the weight of a thousand seeds is about 7.5 grams, which can be used for sowing after slightly drying. Do not lose water, can not be exposed to the sun or long-term storage. Seeds have no dormant period and should be sowed with picking. The temperature should be above 20 ℃ when germinating. Generally, the seeds can germinate about 10 days after sowing, and the germination rate is about 50%. Seedlings generally need to be cultivated for 2 years before they should be on the pot or out of the nursery. Cuttings are carried out in late spring and early summer. 1-2-year-old shoots are cut into segments every 15 cm and inserted into wet sand beds. Roots can take root in about 1 month, nursery in 1 and a half months, and nursery in the following year or the third year. If it is used for twig shaping, it should be started in the second year of seedling. The main way of propagation of Forsythia suspensa is to sow and raise seedlings, and it can also be propagated by cutting. The seeds can be collected all the year round, and the seeds are drenched in wet water for about 1 week after harvest. When the pericarp turns black and rotten, the seeds are rubbed in the water in the basket and bleached to get the seeds.

Roots can take root in about 1 month, nursery in 1 and a half months, and nursery in the following year or the third year. If it is used for twig shaping, it should be started in the second year of seedling. Seed breeding after the fruit turns yellow in winter, the seeds are washed and dried before sowing. After 2 or 3 weeks, it germinated and was cultivated in flowerpots when there were two pairs of true leaves. The fine single plant with strong growth, short and thick branches, dense and full flowers and fruits, free from diseases and insect pests was selected as the mother plant, and the ripe fruits picked from September to October were dried and then stored in sand, that is, a storage pit with a depth of 1.2m, a width of 0.8m and (depending on the number of seeds) was dug, and forsythia seeds and wet sand were fully mixed in the proportion of 1 ∶ 3, and the humidity of sand should be loosened without dripping. Then the seeds of the first layer of sand in the soil layer are buried in the pit, and the soil cover is slightly higher than the ground; the seeds are sown in the first half of March in the south and in the first ten days of April in the north; the sowing amount is about 150kg/ hectare, and the seeds are spread evenly into the ditch according to the row spacing 25cm, and the seeds are evenly scattered in the ditch, slightly suppressed after covering the soil 2cm, and seedlings can emerge in about 20 days; the seedlings should be loosened, weeded and fertilized in time. Seedling height is 5 ~ 6cm and seedling height 10~15cm is the second time. It is necessary to loosen soil and weed, irrigate and keep soil moist at seedling stage, but forsythia is also afraid of flooding. In rainy season, ditches should be opened in time to avoid stagnant water and rotting roots. Thin fertilizer should be applied frequently at seedling stage, and urea 30~75kg/ ha or ammonium sulfate 75~100kg/ ha should be applied each time to promote stem, leaf and plant growth. Generally cultivated for 2 years, the seedling height above 60cm can come out of the nursery. Cuttage seedling old and young twigs can be used as cuttings, cut in sandy soil, maintain about 80% humidity, easy to root, high survival rate. After rooting, a single plant or 2-3 plants can be planted in a flowerpot. Seedlings maintained in the open air, if the growth is not symmetrical or the branches are too long, it can be adjusted by coring or pruning in time. It is appropriate to choose a semi-shaded, ventilated and cool environment. Summer light should not be too strong, easy to burn leaves. Prune over-dense branches in time, strengthen the management of water and fertilizer, and promote more flowering of plants. After entering autumn, increase the light and maintain the good growth potential of the plant. After the weather turns cool, it is necessary to move to the greenhouse for the winter. During the growth period, sufficient water is required for basin change and shaping and pruning in April, and liquid fertilizer is applied every 10 to 15 days from spring to autumn. Pay attention to watering in the dry season and keep the air moist. Appropriate pruning should be carried out after flowering to facilitate re-branching and flowering again. In early summer, 1-2-year-old shoots were cut from fine mother plants and cut into cuttings with 20~25cm length (with 3 nodes). Soak the 1min at the lower end of the cuttings with 500 × 10E-6 rooting powder (ABT) or indolebutyric acid (1BA) solution, remove it and hang it slightly. In the border made in advance, the cuttings were pierced with iron strips or small wooden sticks according to the row spacing of 5cm × 20cm, and the cuttings were inserted into the hole, and then watered, rooting and sprouting in about 1 month, the plants with high 50cm could be grown in the same year, and then transplanted in the field in the following spring. There are many drooping branches of Forsythia suspensa, which can be bent and pressed into the soil from March to April in spring, and the burying place is buried in fine soil with a knife, where it can take root and form seedlings. From winter to the early spring of the second year, the seedlings can be cut off from the mother with roots and transplanted in the field. Forsythia suspensa has a developed root system and strong germination ability. After defoliation in autumn or before sprouting in early spring, the root tiller seedlings around the plant rhizosphere can be dug and planted separately. The common diseases and insect pests of Forsythia suspensa are aphids, caterpillars, sunburns and so on. Aphids and caterpillars are mainly controlled by biological control, combined with pruning and pruning in autumn to reduce the occurrence of aphids and caterpillars. 1000 times omethoate solution can also be used for foliar spraying. Sun burns are mainly used to avoid direct sunlight in hot summer, and proper water spraying and shading are needed. False forsythia should pay attention to the control of two kinds of insect pests. The main results are as follows: (1) the larva drills into the xylem pith of the stem, and in serious cases, the injured branch can not blossom and bear fruit, or even the whole plant dies. Control methods: remove litter and weeds in winter, eliminate overwintering eggs; cut off the damaged branches and burn them in time; plug wormholes with 40% dimethoate EC 500 times or 80% dichlorvos solution. (2) snails are mainly harmful to flowers and young fruits. The method of control is to sprinkle lime powder around the plant in the early morning, and it can also be caught and killed manually.
