Forsythia suspensa has a broad prospect, so many people want to plant Forsythia suspensa. So do you know what economic benefits it has? The following is the economic benefits of planting forsythia for you, I hope it will be useful to you.
economic benefits of planting forsythia suspensa
forsythia suspensa, also known as huanghuatiao, Lianshue, Qingqiao and Luoqiao, belongs to the deciduous shrub forsythia of Oleaceae, which is mainly distributed in Shanxi, Hebei, Shaanxi, Gansu, Ningxia, Yunnan and other provinces in China. Relevant investigations show that forsythia suspensa, as a highly adaptable medicinal shrub, is widely distributed in Yangcheng, Qinshui, Lingchuan, Zezhou and other counties of Jincheng City, Shanxi Province, with abundant wild resources. According to preliminary statistics, there are more than 2, mu of wild forsythia in the city, and the total annual output of forsythia is 4.47 million kilograms. At present, a trading, warehousing and logistics center for Chinese herbal medicines has been built, initially forming a certain production and marketing market and industrial scale; It is planned that the planting area will reach 1.5 million mu by 22, and a national high-quality forsythia suspensa planting base will be built.
Forsythia suspensa is the first choice for treating cold and fever because of its special pharmacological effects. Although wild Forsythia suspensa is widely distributed, its output is far from meeting the market demand. Artificial cultivation has a large development space, and with the characteristics of low planting cost and easy growth, it can be used as an important industry to promote people in mountainous areas to increase their income and get rich. In addition, forsythia suspensa can also be used as a greening and beautifying landscape plant, especially in the spring flowering season, when yellow flowers are everywhere, it becomes a beautiful landscape, which can add a unique landscape to the development of tourism. Therefore, planting forsythia suspensa on a large scale can not only meet the demand of domestic and foreign medicinal markets, help farmers in mountainous areas get rid of poverty and become rich, but also effectively improve the ecological environment. It is a green industry with economic, ecological and social benefits. Planting method
Propagation method
Forsythia suspensa can be propagated by seeds or cuttings.
seed propagation: direct seeding in the south in early and middle March, and in the north in early April, dig a small pit with a depth of about 3 cm in the prepared pit, select mature and full seeds without diseases, sow 5-1 seeds in each pit, cover the soil and press slightly to make the seeds closely combine with the soil. Generally, it will blossom and bear fruit after 3-4 years. On the leveled and raked seedbed, a ditch with a depth of 1 cm is opened according to the row spacing of 2 cm, and seeds are mixed with fine sand and evenly spread into the ditch, covered with soil and slightly pressed, with 2 kg of seeds per mu. Seeding in spring is about half a month, and the seedlings are fixed when the height is 5cm. When the height is 1cm, loosen the soil and weed, and topdressing with 1kg urea per mu, and watering with water to promote the growth of seedlings. Transplanting before germination in autumn or spring of the following year. 12 cm per plant spacing? 15 cm, hole diameter 3 cm, apply 5 kg of miscellaneous fertilizer, mix with soil evenly, plant 2-3 seedlings, fill them to half the hole, lift the seedlings slightly to stretch the roots, and then cover them with soil to fill them up, which is practical. If the soil is dry, water it after transplanting, and then cultivate the soil to preserve moisture after water seeps.
cuttage propagation: on rainy days in summer, cut the middle and upper parts of 1-2-year-old shoots into cuttings with a length of 3 cm, and plant spacing on the seedbed is 5 cm? 3 cm, open a ditch with a depth of 2 cm, put it obliquely in the ditch, then cover the soil and press it tightly to keep the bed moist, so that it can take root and survive that year and transplant it before germination in the next spring.
field management
in the seedling stage of seed propagation, weeding, loosening soil and thinning seedlings when the seedling height is 2 cm. Leave 2 plants in each hole during seedling thinning, and water them in time. When the seedling is 3-4 cm high, dilute feces and urine water can be applied once to promote its growth. When the trunk is 7-8 cm high, the top tip is cut off, and many side branches are produced, and the main branches are cultivated. After that, 3-4 strong branches are selected from the main branches to cultivate the secondary main branches, and the lateral branches are released. Through shaping and pruning, they form a natural happy branch type with a hollow outer circle, ventilation and light transmission, sparse branchlets and early fruiting. Cut off the weak branches, the long branches and the pests and diseases at any time. Farmhouse manure, phosphorus and potassium fertilizer can be applied in the fruit-bearing period to promote early fruit-setting.
harvesting and processing
medicinal ingredients? Qingqiao? 、? Huang Qiao? (also known as Lao Qiao) two kinds. ? Qingqiao? In early September, when the peel is blue and immature, pick it, cook it in boiling water for a while or put it in a steamer for about half an hour, then take it out and dry it. It is better to be green. ? Huang Qiao? In early October, when the fruit is ripe and yellow, and the shell is cracked, it is harvested, and the seeds (for seed use) and impurities are screened out, and the product is dried in the sun, preferably with yellow color, thick shell and no seeds. Cultivation techniques of forsythia suspensa
land preparation
land selection
It is best to choose sandy soil with deep soil layer, loose and fertile soil and good drainage for seedling raising; It is best to use sandy soil (with good permeability and easy rooting) for cutting seedling, and it should be close to the place with water source for irrigation. It is necessary to choose mountainous areas or gentle slopes with thick soil layer, fertile and loose soil, good drainage, and sunny leeward for patch cultivation, so as to facilitate cross-pollination of different plants and improve the seed setting rate of forsythia suspensa, and generally dig holes for planting. Can also use wasteland, roadside, field edge, corner, in front of the house, yard gap sporadic planting.
after land preparation
before sowing or planting, dig the land deeply and apply sufficient base fertilizer, and apply 3 kilograms of base fertilizer per mu, mainly manure, and spread it evenly on the ground. Turn it over about 3 cm deep, level the rake and carefully work the border. The border is 1.2 meters wide, 15 cm high, 3 cm wide, and the border surface is tile-backed. Planting holes should be dug in advance. Plant after applying sufficient base fertilizer.
Seedling raising
Forsythia suspensa can be propagated by seed, cutting, layering, rameting and other methods, and seed and cutting propagation are the main methods in production. > > > More exciting on the next page? Economic benefits of planting forsythia suspensa?
