How to raise day lilies, the culture methods and matters needing attention / suitable exploding pot of day lilies

Because the efficacy and function of day lilies are very many, so there are many people who raise it. It is cultivated in many places in China, and it can even be wild, but if you want to raise it well, you still need certain skills and methods. So how to raise day lilies? Let's take a look at the breeding methods and points for attention of Hemerocallis.

Growth environment of Hemerocallis

Before we know how to raise day lilies, we need to know what kind of environment it likes. Day lilies like humus-rich, well-drained soil and moist and warm environment, but they are highly adaptable, drought-resistant, cold-resistant and semi-shade-resistant, so they are planted in both the north and the south.

How to raise Hemerocallis

1. Soil

Although Hemerocallis does not have high requirements for soil, in order to make its growth more robust, the soil should be sandy soil with more humus, loose, good drainage and permeability, and can be made of rotten leaf soil, garden soil and river sand if there are conditions.

2. Temperature

Hemerocallis is relatively cold-resistant and heat-resistant, it can also survive the winter smoothly in the open field in North China, it can be seen its ability to adapt to temperature, but in the environment of 15-25 degrees, its growth is the fastest, so if you want it to grow well, it is best to control the temperature at about 20 degrees.

3. Lighting

Day lilies like the sun and can grow normally in a semi-shady environment, so if conditions permit, they can be kept in full light or managed in a ventilated and semi-overcast place.

4. Fertilization

Topdressing begins in the second year after planting, the first time is when the new bud grows to about 10 cm, the second time is when the scape is trimmed, and the third time is before flowering, fertilization is mainly liquid fertilizer, which can promote its growth and flowering, so fertilization is very important in the breeding methods and matters needing attention of Hemerocallis.

5. Watering

Day lilies are more drought-resistant, but they prefer humid environments, so they can be watered by climate change during the growing season, less watering or no watering in the rainy season, and watering every 3-5 days in summer to prevent the soil from being too dry.

6. Prevention of diseases and insect pests

The common diseases of Hemerocallis are leaf spot, leaf blight, rust and so on, and the common pests are red spiders, aphids and so on. Keeping the environment clean, tidy and ventilated, and timely fertilization to improve its resistance to diseases and insect pests can play a good preventive effect.

Matters needing attention in Hemerocallis Culture

1. When watering, do not let waterlogging appear in the soil. If so, check whether the drainage of the soil is good, and eliminate the waterlogging in time. Pay attention to the soil wetting in the rainy season and avoid soaking in the water for a long time.

2. Before remanufacturing, the soil should be disinfected. Potassium permanganate can be used to irrigate the soil, or it can be dried in the sun for a few days to ensure that it is free of germs and eggs.

3. Before flowering, we can mainly supplement phosphorus and potassium fertilizer, and at the same time, 0.2% potassium dihydrogen phosphate can be sprayed, which can make the flowers more colorful, larger and prolong the flowering period.

How to raise Hemerocallis to explode

In addition to doing well the above points, if you want to make Hemerocallis burst, it should also be pruned in time, because the root system of Hemerocallis has a tendency to move upward to the surface year by year, so it should be pruned in combination with soil cultivation, and at the same time, the flower stem should be cut off after the flower fade to avoid nutrient loss.

Breeding methods of Hemerocallis grandiflora Reproduction precautions of Hemerocallis

Hemerocallis, also known as Hemerocallis, is a perennial herb of the genus Hemerocallis in Liliaceae. it has special tolerance to alkaline soil and can be used as a rare greening material for oil fields and tidal flat zones. it can also be used to arrange all kinds of flower beds, road barriers, sparse forest and grass slopes, and can also make use of its dwarf characteristics to do ground cover plants. Let's take a look at the breeding methods of Hemerocallis.

Morphological characteristics of Hemerocallis davidii

Hemerocallis hemerocallis fleshy rhizome is short, divided into fleshy root and whisker root, fleshy root is fusiform, whisker root grows on fleshy root. With short rhizome, leaves basal, distichous, leaf blade linear, ca. 30-45 cm long and 2-2.5 cm wide. The flower stem is higher than the leaf, branched above, the floret is 2-4, fragrant, the flower is large, with short pedicels and large triangular bracts. Corolla funnelform or campanulate to campanulate, lobes curved, florescence from July to August. Capsule ellipsoid, slightly triangulate, ca. 2 cm.

Growth habits of Hemerocallis davidii

Hemerocallis is born under forests, wetlands, meadows or grasslands at low elevations. it has strong cold tolerance, sufficient light tolerance, semi-shade tolerance and loose soil requirements, but it is better to use permeable soil with high humus content and good drainage. Fertilizer is often applied during the growing season. In the north, the underground tubers should be dug up before frost and stored in an environment with a temperature of about 5 ℃. The optimum temperature for open field cultivation is 13-17 ℃. Resist the infection of diseases and insect pests, and have strong tolerance to noise and dust.

The Propagation method of Hemerocallis

1. Ramet: when ramet, take part of the tiller of the plant cluster 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, and then plant it. Planting should be carried out on a sunny day, digging seedlings, dividing seedlings and planting seedlings at the same time, with as little root injury as possible, so that the seedlings are slow and fast, usually once every 2 to 3 years, in order to ensure the exuberant growth of the plant.

2. Sowing: Hemerocallis enters the seed collection period around September every year, and sows in the next spring. The nursery bed should be fertilized with sufficient bottom fertilizer first. The bed is 1.3 to 1.7 meters wide and 30 meters long. 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.

3. Split bud: flower bud refers to the small plant on the flower stem of Hemerocallis, which can be cut from the flower stem and can be further divided before planting if it is large. The transplanted flower buds can take root after a week, and the rooted flower buds can be used to propagate plants, increase the number of plants planted, and finally improve the economic benefits.

4. tissue culture: young leaves, filaments and flower moss were used to culture plants. the method was to induce callus from young organs, and then to culture young plants with proper medium under suitable conditions such as warm and wet phosgene. Then the seedlings were pseudo-planted in the nutrition bowl, and the seedlings were cultivated for a period of time, and then planted.

Culture methods of Hemerocallis vulgaris

1. Planting: Hemerocallis does not have strict requirements on soil, and can grow normally in saline-alkali land and sandy land, but the permeable soil with high humus content, deep soil layer, superior irrigation conditions and good drainage is the best. When preparing the soil, apply a certain amount of organic fertilizer, and then leveling, raking fine, the whole bed, the width of the bed is 2-3 meters, easy to manage. Trench or hole-digging planting, planting should not be too deep or too shallow, plant spacing of 30 cm to 40 cm is appropriate, after planting cover soil compaction, watering through.

2. Watering: Hemerocallis does not need to be watered if the weather is not very dry and early during the whole growth and development period, but if the soil moisture is insufficient after sprouting in spring, the number of flowers will be affected, so it should be watered in spring in the spring drought area. Adequate water supply should be provided during the growing season, and the soil should be kept loose and moist, otherwise it will affect the normal flowering and flower quality of the plant.

3. Fertilization: Hemerocallis hemerocallis was fertilized at the right time from the second year of planting, which had a great influence on the flowering of the same year. Liquid fertilizer had better be applied three times in the whole year, the first time when the new bud grew to about 10 cm, the second time when the flower was seen, and the third time it was applied 10 days after flowering. Hemerocallis hemerocallis has a long flowering period and has a large demand for nitrogen, phosphorus and potassium. In addition to applying sufficient basic fertilizer (suitable for rotten cow manure or pig manure), it is also necessary to apply fertilizer according to the needs of different development stages.

4. Weeding: after planting Hemerocallis hemerocallis, in order to ensure the normal growth of seedlings, weeding should be timely ploughed and weeded, generally divided into two methods: one is to use herbicides to remove weeds in the field, and the other is to loosen the soil mechanically or manually to remove weeds in the field.

5. Insect pests: the common diseases of Hemerocallis are leaf spot, leaf blight, rust, anthracnose and stem blight, etc., and the main pests are red spiders, aphids, thrips, leaf miners and so on. The disease can be controlled with 3000-fold spray of 75% chlorothalonil.
