In the application of sufficient base fertilizer, 500kg of rotten organic fertilizer or 5kg of urea and 3000-4000 kg of farm manure are applied per mu, which are scattered on the border surface and mixed evenly with the soil.

2. Seed germination

Generally, the seeds can be collected from 10 to winter, and the seeds can be collected from the plants that have been growing for more than 30 years and are free from diseases and insect pests. The seeds are soaked in water after harvest, and then the pericarp is rubbed off to get the seeds. Soak it in 80 degrees hot water for 5-6 hours in early March, remove it and mix it with twice the sand, put it indoors, 20-25 cm thick, spread wet sand on top to prevent the seeds from being exposed, cover the seeds with a layer of plastic film, keep them warm and moisturizing, and promote the seeds to germinate. at the same time, they should be turned frequently to make the upper and lower seeds have the same humidity and germinate neatly, and the seeds can be sown when the seeds are 1/3 split.

3. Sowing and raising seedlings

Generally use field ridge sowing, sit ridge according to 50~65cm, open shallow ditch on ridge when sowing, ditch depth about 7 cm, apply base fertilizer after sowing, cover soil 5 cm, compaction. After sowing, we should pay attention to the application of soil, and at the same time, pay attention to the harm of seed flies. After the seedlings are completed, the seedlings are divided into 2-3 times, and the seedlings are fixed according to the plant spacing of 10-15 cm. From May to August, it is time for weeding in the field, keeping the nursery clean, paying attention to drainage and waterlogging prevention in the rainy season, digging seedlings and grading after falling leaves and before the land is frozen, pseudo-planting over the winter, and transplanting the following year.

4. Transplanting management

After the soil thawed in the next year, the annual seedlings were transplanted according to the row spacing of 70 × 40 cm, and the watering and fertilization should be carried out at the same time. Usually, after two years of cultivation, the large seedlings with a height of 1 meter were selected for planting in the third year, and the unqualified wheat was planted one year later. After planting, it is necessary to strengthen management, apply sufficient water and fertilizer, enhance plant disease resistance, and do a good job in pest control so as not to harm plant growth and development. The medicinal Fructus Sophorae can be obtained by harvesting the buds in summer, drying them in time, and removing branches, stems and impurities.
