What is the typical per-mu yield of green forsythia?
Per-mu yield of green forsythia:
On flat land, green forsythia yields 480-600 kg of green forsythia per mu; at 15 yuan per kg, the output value per mu is 7200-9000 yuan. The suitable density on flat land is about 400 plants per mu, and in the full fruiting period each plant produces 1.2-1.5 kg of commercial green forsythia. | After deducting costs of 1500 yuan in total for seeds, manual management, etc., the net income per mu can reach 5700-7500 yuan. If you save your own seeds, the cost will be further reduced.
When green forsythia is planted on barren hills, the yield is 800-200 kg of green forsythia per mu, and the suitable density is about 200 plants per mu. On sunny slopes or semi-sunny slopes, the yield of a single 3-year-old plant of weeping forsythia grown from new shoots can reach 0.4 kg; in the eighth year it enters the full fruiting period, and the yield of a single plant can reach 1 kg.
Efficacy of green forsythia:
In traditional Chinese medicine it is bitter in taste and slightly cold in nature. It clears heat and detoxifies, disperses nodules and reduces swelling. In Mongolian medicine it is bitter in taste and cool in nature. It clears “Xieri” and stops diarrhea. Indications: in traditional Chinese medicine it treats the early stage of febrile disease, wind-heat common cold, fever, restlessness, sore throat, macules, erysipelas, scrofula, carbuncle and sore swelling, acute nephritis, and heat strangury. In Mongolian medicine it treats jaundice, intestinal stabbing pain, “Xieri” disease, and intestinal heat.
Growing conditions for green forsythia:
Temperature conditions: the optimum growth temperature for green forsythia is 18-20°C, and growth is inhibited when the temperature is above 35°C or below -15°C. The suitable temperature for sowing is 10-15°C, the optimum temperature for the flowering period is 18-20°C, and the frost-free period during the growing season must be more than 170 days.
Water requirements: within its natural distribution area, an annual precipitation of 800-1000 mm and a relative humidity of 60%-75% are required. If there is too much rainfall and the humidity is too high, lodging and moldy pods are likely to occur.
Light conditions: green forsythia prefers a sunny, well-lit environment and requires annual sunshine hours greater than 1500 hours. Soil conditions. Weeping forsythia is not strict about soil and can grow normally in neutral, slightly acidic or slightly alkaline soil, but it grows better in well-drained sandy loam rich in humus.
Benefit analysis: economic benefits. Weeping forsythia can be planted in all four seasons, and one planting can bring benefits for many consecutive years, with considerable economic benefits. Barren hill planting. When green forsythia is planted on barren hills, the suitable density is about 200 plants per mu, and it can be mixed with other shrubs. On sunny slopes or semi-sunny slopes, the yield of a single 3-year-old plant of weeping forsythia grown from new shoots can reach 0.4 kg; in the eighth year it enters the full fruiting period, and the yield of a single plant can reach 1 kg.
