6-10 parts of fresh cow dung were used for cattle dung dressing, mixed uniformly with 1 part of Zanthoxylum bungeanum seeds, and placed in a cool and dry place. The cow dung and the seeds can also be stirred well, buried in a deep 30 cm pit, covered with 10 cm thick soil, cover the grass after the cover, the next spring to take out the broken along with cow dung sowing. The cellar was stored in a place where the soil was moist and well drained. A small cell with a diameter of 1 m, a bottom diameter of 0.4 m, and a depth of 0.8 m was excavated. After the seeds were put in, they were spread into 10-15 cm thick seed layers and covered with 10 cm of soil. Fill 1 lb of water, wait for the water to seep, and then cover with a layer of wet soil of 3 cm. Cover the weed with the top of the pit. In the spring of the following year, the seeds will inflate and they can sow. One block of dry seed is collected from the clod and mixed with 1 to 1.5 parts of cow dung, grass ash and loess, or 1 part of seed, 2 parts of cow dung and 2 parts of loess. The mud cake is dried and then the mud cake is dried. After putting the slurry in the mud to dry, it can be stored in a cool, dry and ventilated room. The mixed sand stores are selected for high topography, good drainage, and digging of storage pits at ventilation and shady areas (bogey groundwater is too high). Pit depth is 0.8 to 1.3 meters. Mix the seeds with 3 times the wet sand of the seeds. The humidity of the sand is better if the fingers can work together without water.
