Variety selection is suitable for wintering cultivation of cultivars such as Laiyang wolfberry and Shandong big leaf lice. Seeding overwintering in North China is generally planted in September-November and harvested in stages from March-May in the following year. The seeds must be crushed and the seeds must be smashed before sowing, and the seeds can be sown after sowing. Seeds were soaked in fresh water for 12 hours to 24 hours before germination and then germinated at a temperature between 20 and 25 degrees. In order to use live broadcasting, seeding methods include seeding or broadcasting, with 4 kg to 5 kg per acre, flattened and then watered. When sowing, first pour enough water into the pot. After the water is infiltrated, spread the soil on the 1st floor and then sow the seeds and cover the soil. Post-seeding and pre-winter management generally require watering 2 to 3 times from sowing to emergence, and the soil should be kept moist so that the seeds germinate and emerge. After the small seedlings are out of control, watering is properly controlled. When the seedlings about 4 cm -5 cm high with water, fertilizer, apply ammonium sulfate 10 kg -15 kg per mu, and later to control the watering, to prevent over-winter seedlings grow too fast too soft and reduce the ability of cold resistance. Overwintering quail should be poured with frozen water before freezing and human urine should be poured once with water. After the water is applied, the surface of the mulch is covered with crushed horse dung and hay to prevent winter and overwintering, but the coverage should not be too thick. After the return to green management, the cover is removed in the late spring, and after the soil is loose, the green water is burned back, and 10 to 15 kg per mu of urea are chased with water, and the water and seedlings should be watered in due course. Spraying with 20 mg of gibberellic acid per kilogram for 7 days to 10 days before harvest can increase yield. In the growth process, the main disease is aphids, which can be sprayed with 50% of a 2000-3000 dilution of WP wettable powder or 6000 times of 40% fenvalerate EC. The harvested pods are generally rooted and planed, yellow leaves are removed, and baskets are washed and washed after tying. Wolfberry is a seasoning dish with a small amount and should be harvested in stages during the management of water and fertilizer. China Agricultural Network Editor
