Pick black fruit in January. Picking and stacking by the thickness of 30 cm, after 5-7 days of ripening, put into the water to wash the skin and flesh, and put it in the back shade to dry. Avoid exposure, then pick up seeds and store them for later use. Seed treatment: Before sowing, soak the seeds in warm water of 35-40°C for 24 hours, remove the wet sand mixed with 2-3 times, cover the plastic film, and put them in a warm place to germinate. When the splitting rate reaches 50%, it can be sown. Sowing period: Spring sowing can be in early March. Pre-planting seedbed preparation: Drought-resistant tillage seedbed, generally ploughing 50 cm, applying enough base fertilizer, applying basal fertilizer 6000-7500 kg per 667 square meters, ammonium bicarbonate 40-50 kg, fine leveling, removing residual weeds. In order to prevent the underground pests, 1.5-2 kilograms of Alzheimer's powder or 0.15-0.25 kilograms of phoxim emulsions can be applied per 667 square meters. Appropriate application of some zinc sulfate or ferrous sulfate to prevent seedling disease. It can be 1 meter wide, 20 centimeters high and 10-15 meters long. Sowing: Spread the seeds in a full-size cabin and use 1.0-1.2 kg per 667 square meters. Flatten the surface of the car first, fill it with water and fill it with water. When the water seeps, soak or store the sand and add it twice as much sand. Spread it evenly into the car, cover it with 0.5-0.7 centimeters of sand and cover the grass or Cover film. Management after sowing: The management of the moisture after sowing is very important and directly affects the emergence rate. As the honeysuckle seeds are small, the seedlings of the soil should be prevented from cracking before they are excavated. Should be checked daily, cover the straw curtain in the morning or evening spray water with a watering can, cover film should pick spray, that is, water spray on the water shortage. When the seedlings were unearthed about 30%, the cover was removed and after the shoots were flushed, the water was often kept moist to keep the surface moist. Seedling growth, weeding, and watering often occur during the seedling growth period. According to the seedlings, nitrogen fertilizer can be applied, which is 7-10 kg per 667 square meters. When the seedling height is 15-20 centimeters, it will be picked up and new shoots will be sent out. After 2-3 times in succession, there will be 4-8 branches per plant in July, and it will be planted in the fall.
