I. When to harvest Sichuan pepper seeds

From August to September is the season for harvesting Sichuan pepper seeds, and also a good time for Sichuan pepper seedlings. At present, the main varieties include Dahongpao (Shitou), Xiaohongpao, Jinjiao, Youjiao and other strong varieties. For seed collection, choose high-quality middle-aged trees, and sow seeds from fruits that are fully mature with purple pericarp and seeds that are blue-black in appearance, intact, and disease-free.

First, select freshly picked Sichuan pepper seeds from the seeds, then soak them in warm water in a 1% alkaline water or 1% laundry detergent solution for two days (with the water submerging the seeds), and repeatedly rub and wash the seed coat. Before the seed surface turns grayish-white, rinse the alkaline solution off the seed coat with water and mix it with plant ash, after which sowing can be carried out.

III. Choosing a seedbed for Sichuan pepper seeds

1. Sichuan pepper likes sunlight and needs sufficient sunlight exposure to grow well. Therefore, the seedbed should be on a leeward side, with deep soil, fertile and well-drained sandy soil, and in a place with sufficient light.

2. Before sowing, finely level the ground, break up soil clods, and make it loose on top and firm below. In combination with deep plowing of the whole plot, apply 4,000 to 5,000 kg of decomposed organic fertilizer per mu, 8 to 10 kg of urea, 30 to 40 kg of superphosphate, 50 kg of peat or 10 to 15 kg of potassium sulfate.
