1. Site selection: Choose a place with shelter from the wind, abundant sunshine and fertile soil as the planting site. 2. Reasonable close planting: the planting spacing of day lily is 10- 15cm, and the row spacing is 60-75cm. 3. Scientific fertilization: apply high-quality farmyard manure and calcium superphosphate to day lily once in autumn. 4. Field management: After the day lily is harvested, the sick and disabled bodies in the plot will be removed and burned in time.

How to plant day lily 1, land selection

Day lily is suitable for growing in fertile, loose and breathable soil environment. Sandy loam or loam can be used for planting, and daylily has poor cold tolerance. It is best to choose a sheltered and sunny place as the planting place.

2. Reasonable close planting

When planting day lily, reasonable close planting should be carried out to increase the number of tillering, bolting and budding of plants and improve the yield of day lily. Generally, the plant spacing is 10- 15cm, the row spacing is 60-75cm, and 2-3 seedlings are planted in each planting hole.

3. Scientific fertilization

Day lily belongs to fleshy root system, so it is not suitable to apply thick fertilizer when planting to avoid root rot. When autumn seedlings wither after frost, high-quality farmyard manure and calcium superphosphate can be applied once to promote the development of underground bulbs.

4, post-management

During the management of day lily, attention should be paid to the prevention and control of diseases and insect pests such as rust, leaf blight and aphids. After the rain, the accumulated water in the field should be drained in time to reduce the soil moisture, and the sick and disabled bodies in the plot should be removed and burned in time after harvest.
