The propagation method of Rhizoma Curculiginis: seed propagation or ramet propagation.

1, land selection and land preparation: it is better to choose sunny sandy loam with good drainage, deep soil layer and rich humus in mountainous areas, hills and plains. Dig all the land, dig 30 cm deep, remove weeds, apply base fertilizer, break the soil and rake it flat, make the border with a width of 1.2 m, and open the drainage ditch.

2. Seed propagation: After the seeds are collected in September, the seeds are mixed and stored in wet sand. Sow in March-April of the following year. When sowing, shallow furrows of 2-3 cm are opened, and the furrow spacing is 20 cm. After the seeds are drilled, cover them with fine soil to cover the seeds, then cover them with grass to spray water, and pay attention to keep the soil moisture in the future. When the seedling height is about 5 cm, it can be properly thinned. Two years later, in winter and spring, the seedlings were dug out and transplanted, and the hole spacing was 20-25 cm, and 3-4 plants were planted in each hole. After planting, compact the roots and spray water.

3. Propagation by ramets: Dig out the mother plant in winter and spring, carefully peel off the tillering buds, so that each ramet has 1-2 buds, and directly plant them in holes, and plant 2-3 ramets in each hole.

field management

1, intertillage weeding: Because the whole growth period is long, intertillage weeding should be done every other month 1 time.

2. Top dressing: Top dressing with nitrogen fertilizer at seedling stage. After planting, apply 1 time of human excrement and urine or compound fertilizer in spring and summer, and apply 1 time of phosphorus and potassium fertilizer such as manure, superphosphate and turf mud in autumn and winter. After each topdressing, it should be combined with soil cultivation.
