Sichuan peppercorn is a seasoning ingredient, and the Sichuan peppercorn tree is a deciduous shrub that grows quickly, bears fruit early, begins to bloom and bear fruit 2-3 years after planting, bears a large amount of fruit at 4-5 years, and has a growth lifespan of 30-40 years, benefiting from a single planting for a long time.
Sowing Time for Sichuan Peppercorn
Sowing Sichuan peppercorn seedlings can be done in autumn and spring.
1. Spring sowing is usually adopted in the northern regions due to the cold winter. Spring sowing should be around the time of the Spring Equinox, directly sowing the stored seeds. In areas with severe spring drought, autumn sowing is better. After harvesting Sichuan peppercorn seeds in autumn, proper storage should be ensured. Sichuan peppercorn seeds can be stored using sand or made into cakes with cow dung.
2. Autumn sowing involves sowing seeds immediately after collection. In southern regions and areas with severe spring drought, autumn sowing is generally better.
Issues to Consider When Sowing Sichuan Peppercorn
1. When collecting Sichuan peppercorn seeds, select medium-aged trees (10-20 years old) that are strong, productive, of good quality, and free from diseases and pests. Harvest when the peel of the Sichuan peppercorn fruit is completely purple and the inner seed coat has turned blue-black.
2. Sichuan peppercorn seeds should not be exposed to direct sunlight to avoid reducing their germination ability.
3. The seeds are hard, oily, and have poor water permeability, slow germination, and low germination rate. Therefore, degreasing treatment and storage must be performed before seedling raising.
Method 1: Remove the iron head from the stone pestle (or use a small stone pestle for pounding chili powder at home), and gently crack the outer shell of the mature, sun-dried, plump Sichuan peppercorn seeds in the pestle. After about 3 minutes, when the outer shell of most seeds has cracked, they can be sown directly. As the outer shell cracks, moisture easily enters, causing the embryo to swell and push the shell apart, thereby greatly increasing the germination rate.
Method 2: Use 25 grams of soda per kilogram of Sichuan peppercorn seeds, add water to submerge the seeds, soak for two days, rub off the oil on the seed coat, remove the chaff, and then sow directly.
Method 3: Soak in a 1:200 laundry detergent solution for two days and two nights, rub the oil from the surface of the seeds, wash repeatedly with clean water, and then place in a shaded area.
Sowing Sichuan Peppercorn Seedlings
1. Seedbed: The seedbed should be flat, sheltered from the wind, with fertile and loose soil. After careful land preparation, bed making, sufficient base fertilizer application, and soil disinfection, sowing can be carried out. Apply 2000 kilograms of farm manure and 100 kilograms of phosphate fertilizer per mu, deeply plow and raise ridges, with a bed width of 1 meter.
2. Sowing Method: For easy management, generally use drill sowing with a row spacing of 20-25 centimeters. Make a furrow 5 centimeters deep, cover with 1 centimeter of soil after sowing, and apply 4-6 kilograms of seeds per mu. After sowing, cover with straw to keep the soil moist.
3. Seedbed Management: After seedlings emerge, remove the covering straw. When the seedlings are 4-5 centimeters tall, start thinning, usually 1-2 times, with a spacing of 10-15 centimeters. In June and July, apply decomposed animal manure at 300-400 kilograms per mu or chemical fertilizer at 6-8 kilograms per mu, combined with watering. Ensure drainage and prevent waterlogging during the rainy season, strengthen cultivation, and control diseases and pests. Generally, seedlings can be transplanted when they are 70-100 centimeters tall.
