Day lily, also known as day lily, is a perennial herb perennial plant. It originated in the warm zone of Europe and Asia and has been cultivated in China for thousands of years. Let's learn about the planting method of day lily.

First, the economic role of day lily The edible part of day lily is the bud that grows on its stem and has not yet fully blossomed. It contains more carotene, protein, carbohydrates, calcium, phosphorus and iron. Day lily is a nutritious vegetable, which is not only very popular in China, but also an important raw material for foreign trade export.

Second, the propagation mode of day lily mostly adopts ramet propagation. Generally, when the old plants germinate 2-3 inches in spring, the ramets can be dug up. Plant two or three bulbs as a plant. Generally, it can be planted sporadically in front of or behind the house or in a large area. When planting, the plant spacing is 2 feet and the row spacing is 3 feet. The size of the planting hole depends on the size of the root ball, and the planting depth is based on the level of the ball with the ground. Before planting, one or two kilograms of soil and miscellaneous fertilizer can be applied to each hole. After planting, root water must be poured to promote survival. Because daylily has strong adaptability, it does not need other fine management. Just before germination every spring, a certain amount of compost should be buried around the root plants.

Third, the management of day lily and the growth of day lily after several years, the underground root plants are easy to spread and stagger, leading to poor plant growth, which directly affects the yield and quality. Therefore, it needs to be dug again every 4 ~ 5 years and propagated by ramets.

If the day lily develops well in the planting year, it can blossom. Flowers are usually picked in the second year. Flowers should be picked every morning, and it is best when the flowers are not fully open. Generally, each plant can take 2 ~ 3 kilograms of flowers every year, and the yield per mu is about 2000 ~ 3000 kilograms. 10 Jin of flowers can make one Jin of dried daylily, and 200 Jin of dried daylily can be made per mu? 300 Jin.

After the flowers are harvested, they should be steamed in time, but they should not be overcooked, which is easy to rot and not form. Then put it in the sun to dry or dry. But no matter which method is adopted, the drying duration should not be too long, which is easy to ferment and reduce the quality.
