Seed price and planting method of Forsythia suspensa

Forsythia, also known as Huanghuagan and Huangshoudan, is a deciduous shrub plant of Forsythia suspensa of the family Liliaceae. it is born in shrubs on hillsides, under forests or in grasses or in valleys and ravines. It is cultivated in all parts of China except South China. It is often used as an ornamental plant and oil plant. Let's take a look at the seed price and planting method of Forsythia suspensa.

How much is forsythia seed per jin?

The price of forsythia seed is about 50-60 yuan per jin, but it varies according to the quality, variety and origin of seeds. Forsythia likes light, has a certain degree of shade tolerance, likes warm and humid climate, is also very resistant to cold, drought and barren, is afraid of waterlogging, and does not choose soil, and can grow normally in neutral, slightly acidic or alkaline soil. Seeds, cuttings, striping, plantlets and other methods can be used for propagation, but seed and cutting propagation is the main method in production.

Sowing method of Forsythia suspensa

1. Sowing time: forsythia seeds are suitable to germinate at higher temperature. According to seed storage and germination, cultivation time can be arranged in spring or winter, spring sowing in early and middle April, and winter sowing before freezing.

2. Seed treatment: forsythia seeds were soaked in 40 ℃ warm water, then germinated with wet sand, often tipped over and replenished with water, and could be sown when part of the seeds were cracked. The seeds can also be soaked in warm water and then soaked in clean water for 24 hours, waiting for the seeds to be fully absorbed before sowing.

3, post-sowing management: forsythia seeds should be covered with thin soil after sowing, usually about 1 cm, covered with grass. Seedlings afraid of waterlogging, gradually remove the covered grass after emergence, seedling height 3-5 cm time seedling, fixed seedling, the current year seedling height can reach about 50 cm.

Planting method of Forsythia suspensa

1. Land selection and soil preparation: forsythia should be planted in mountainous areas with thick soil layer, loose fertility, good drainage, leeward to the sun or gentle slopes, so as to facilitate cross-pollination and improve the seed setting rate of Forsythia suspensa.

2. Fertilization and planting: the forsythia should be fertilized in the hole before planting, and the rotten stable manure or soil miscellaneous fertilizer and appropriate amount of compound fertilizer should be applied in each hole. When planting, the root system of the seedlings should be extended, and the soil cover at the planting point should be higher than the surface of the hole, so as to avoid the sinking of cave soil after rain, which is not conducive to survival and growth.

3. Intermediate ploughing and weeding: forsythia should often loosen the soil and weed at the seedling stage. After planting, weeds should be ploughed and weeded next to the forsythia tree once a year in winter, and the weeds around the plant can be eradicated or pulled out by hand.

4. Rational fertilization: after planting Forsythia suspensa, combined with loosening soil and weeding, rotten stable fertilizer, cake fertilizer or soil miscellaneous fertilizer are applied every winter, the dosage is 2 kg per young tree and 10 kg per fruiting tree. Fertilization can be increased once before flowering in spring and once after pruning.

5. Drainage and irrigation management: forsythia likes to be wet and afraid of waterlogging, so it is necessary to keep the soil moist during planting, ditch irrigation or watering in time during the dry season, and ditch drainage in the rainy season to avoid stagnant water and rotten roots.

6. Shaping and pruning: when the height of Forsythia suspensa is about 1 meter, the top tip of the young forsythia tree is cut off at 70cm and 80cm above the ground after defoliation in winter, and then through coring and multiple branches in summer, 3 or 4 fully developed lateral branches are selected in different directions and cultivated into main branches.
