The seedbed 100~120cm is wide, and every 17~20cm is square. Insert a section of cut root into the soil, and only expose 1.5cm on the outside. Then apply a small amount of thin human feces, cover with soil or stable manure, and water to keep the soil moist. It can sprout in 30 to 40 days. It can be transplanted in the spring of the second year.

When transplanting seedlings must choose sunny days, and must choose sunny, loose soil, fertile, well-drained ground planting.

When transplanting, first dig a good nest, nest width 50~70cm, deep 34~50cm, row spacing 330~400cm, triangle or square and other legal planting. When digging the nest, the topsoil and core soil are stacked respectively, and then the rotten barnyard manure or pond mud is used as base fertilizer; first, the topsoil is put to prevent the base fertilizer from getting hot and affect the plant growth; then the seedlings are put on the fine soil, and then the topsoil is covered with the core soil, and then the seedlings are gently lifted up and suppressed, so that the roots are tightly knotted with soil. It will blossom and bear fruit 2-3 years after planting.
