1. Climate and soil: a warm and humid climate is the most suitable. Fertile sandy loam or humus loam grows well.

two。 Soil preparation: autumn ploughing should be carried out before sowing and base fertilizer should be applied at the same time 6000-8000 jin per mu. Shallow ploughing again in late March of the following year, raked flat to make a border, with a width of 1-1.2m.

3. Planting and seed propagation: sow seeds in shallow trenches according to row spacing 30cm, spread seeds evenly into ditches, cover with thin soil, water slightly, sow 1.5-2jin per mu, raise seedlings on sunny beds, 10-15 days earlier than direct seeding, irrigate once after border leveling, and sow once after water seeps. After sowing, seedlings emerge in 1 thin layer covered with soil, about 10-14 days. When seedlings have 3-4 true leaves, transplant them according to row spacing of 30 × 15cm. Ramet propagation: from the middle of April to the first ten days of May, the holes were opened according to the row spacing of 30 × 15cm. The new plants next to the mother plants were dug out and planted in the holes. 2-3 seedlings were planted in each hole, so that the roots were stretched in the holes, and the soil was compacted and watered.

4. Field management: when the weather is dry, it should be watered in time, and when the topsoil is hardened after hot, dry or heavy rain, it should be loosened in time to reduce water evaporation.
