1, soil preparation. When raising seedlings, we should choose sandy soil with leeward and sunny, deep soil layer, fertile soil and good drainage. Apply 2,000 to 3,000 kilograms of manure per mu, plough deeply and rake carefully, and make a border after leveling, with a width of 1 m.

2. Seed treatment. The seed shell of Zanthoxylum bungeanum is hard and oily, so it is difficult for water to penetrate into the seeds, so it should be degreased. Before sowing in autumn, soak the seeds in an alkali solution (1kg seeds are covered with 25g alkali, and the seeds are submerged with water), take out the seeds, soak them for two days, wipe off the oil on the seed coat, and take them out for sowing; Plant ash can also be used to rub and remove grease from seed coat.

3. Trenching and drilling. Sowing is usually carried out from the end of autumn to before the soil freezes. Ditch 4-5 rows per border, with a depth of 5 cm, and sow 10 ~ 12 kg per mu. After sowing, cover with a layer of fine soil with a thickness of 2 to 3 cm.

4. Early spring management. When thawing in the next spring, it should be suppressed once in time to make the seeds closely combined with the soil, which is beneficial to the seeds to absorb water and emerge. Keep an eye on the nursery and don't let livestock in. In case of drought in early spring, water it in time. A few days after watering, use a shallow hoe to conserve moisture, keep the border surface moist and prevent soil from hardening, so as to increase the temperature and promote germination.
