Introduction to the Propagation methods of Hemerocallis

Because of its short plant and long florescence, Hemerocallis is a polyploid dwarf variety treated by high-tech means, which is very suitable for ground cover plant. Nowadays, Hemerocallis hemerocallis is often used to decorate flower beds and road isolation belts. It is an excellent garden flower integrating foliage and flowers. Artificial propagation of Hemerocallis can be done by sowing, dividing plants, dividing buds and tissue culture.

1. Sowing method:

Sowing is a method of rapid and mass production of seedlings, but because of the low germination rate of seeds, it needs to be soaked and germinated before it can be planted one year after sowing. Enter the seed collection period around September every year, which requires strong plant growth, full fruit and no diseases and insect pests. Sow the seeds in the following spring.

The nursery bed should be fully fertilized first. The bed is 1.3 to 1.7 meters wide and 30 meters long, and drainage ditches are dug on both sides. When sowing, open a shallow trench with a depth of about 3 cm every 20 cm, sow the seeds evenly into the ditch, cover a layer of fine soil, and then cover a thin layer of fine sand. Watering and weeding should be done before seedling emergence, and good soil moisture can be maintained so that seedlings can be planted in autumn. 2.5 kilograms of seeds per mu of seedbed, which can raise 50 to 60 thousand seedlings.

The seeds can also be sowed and sowed in the open field after seed sowing and germination, with a sowing amount of 5 to 7 kg per mu and sown with flat strips. Trench according to the row spacing of 30 cm, about 3 cm deep, sow a seed every 3 to 5 cm, wait for the plant to grow 2-3 leaves, apply thin human feces once. Winter with a small arch shed to protect against cold, strengthen field management after the beginning of spring, can be transplanted in August. Seeds collected from evergreen hemerocallis can be sown directly or stored at room temperature.

Second, the method of dividing buds:

A split bud refers to a small plant on the stem of a day lily. The flower bud can be cut from the flower stem and, if large, can be further divided before planting. The transplanted flower buds can take root after a week. The rooting flower buds can be used to propagate plants, increase the number of plants planted, and finally improve the economic benefits.

3. Tissue culture method:

In tissue culture, young leaves, filaments, flower moss and other organs were used to culture plants. The method is to induce young organs to produce callus, and then use appropriate medium to culture young plants under suitable conditions such as warm and humid phosgene. Then the seedlings were pseudo-planted in the nutrition bowl, and the seedlings were cultivated for a period of time, and then planted. But this method has not been widely accepted.

Fourth, the method of dividing plants:

Dividing hemerocallis clumps is the most commonly used method of reproduction. The operation of this method is simple, the plant is easy to survive and the growth is consistent. Ramet can dig out all the mother plant cluster and replant it, or dig out a part of the plant from one side of the mother plant cluster to make seedlings, leaving behind to continue to grow.

Ramets are mostly carried out before sprouting in spring or after defoliation in autumn. When the ramets are transplanted in spring, they can bolt and blossom in the same year, and in autumn, they can sprout and blossom the following year. Plants with exuberant growth, many buds, good quality and free from diseases and insect pests should be selected when transplanting.

When ramet, dig a part of the tiller of the plant clump as the seedling, dig the part with root, cut it from the shortened stem, cut off the old root, rotten root and diseased root, retain the fleshy root as far as possible, cut it short properly (about 10 cm) and then plant it. Planting should be carried out in sunny days, while digging seedlings, while dividing seedlings, while planting seedlings, as little as possible to hurt roots, so slow seedlings fast. Generally, the plant is divided once every 2 to 3 years to ensure the exuberant growth of the plant.
