1, seed selection

Choose plants that have been growing vigorously for more than 10 years, bearing early fruits, high yield and good quality as trees. Picking Zanthoxylum bungeanum fruit from July to September when the inner seed coat is blue-black. Choose fully mature, plump fruits with purple skin and black inside, and put them in a well-ventilated room to dry after harvesting, so as to avoid losing germination ability due to exposure.

2. Seed treatment

According to the difference between autumn sowing and spring sowing in sowing season, seeds should be treated before sowing. Autumn sowing seed treatment-degreasing treatment. Spring sowing seed treatment-sand storage treatment or cow dung seed dressing. There is still some time before spring sowing after seed collection, in order to prevent the seeds from losing their vitality.

Spring-sown seeds should be dressed with live cow dung before sowing, so as to maintain the activity of the seeds, and all localities can choose flexibly according to the actual situation.

In addition, you can also use boiling water to accelerate germination. Pour 1 seeds into 2 portions of boiling water, stir for 2~3 minutes, and then soak them in warm water every day. After several seed coats are cracked, take them out and put them in a warm place, and sow them after 1~2 days.

3. Soil preparation, fertilization and sowing

Choose sandy loam with flat terrain, deep soil layer, fertile soil and good drainage to establish nursery. Before sowing, deep ploughing, applying base fertilizer and leveling are used as seedbeds. Apply 2000 kg of decomposed farmyard manure, about 10 kg of urea, 0/0 kg of diammonium phosphate and 0/0 kg of potassium sulfate as base fertilizer per mu, mix them evenly, spread them on the surface, and then turn over the soil.

4. Seedling management

Fixed-distance seedling: after the seeds germinate, when the seedlings grow to 3-4 cm high and have 3-4 real leaves, the distance is fixed; When the height of the seedlings is about 5 cm, the seedlings are fixed, and about 45 seedlings are left per square meter.

Intertillage and weeding: Zanthoxylum bungeanum is a shallow-rooted plant, and weeds are extremely unfavorable to seedling growth. The growth potential of Zanthoxylum bungeanum seedlings is weak, and it is at a competitive disadvantage with weeds, which easily leads to grass shortage, which leads to the competition between weeds and Zanthoxylum bungeanum seedlings for water and nutrients and affects the normal growth of Zanthoxylum bungeanum seedlings.

Foliar fertilizer supplement: at the seedling stage of Zanthoxylum bungeanum, the plant growth is small and the demand for nutrients is small. In production management, foliar fertilizer can be sprayed on leaves to supplement nutrients.

Finally, because sowing and seedling raising are easy to degenerate and the goodness of varieties is not easy to preserve, grafting should be adopted to improve the ability of plants to be below adverse environment and promote the improvement of productivity.
