How to raise tiger flowers of wild peony family? How do you plant seeds? How do you breed?

Huyan Hua (scientific name: TigridiopalmamagnificaC.Chen) belongs to the genus Artemisia of the family Paeonaceae, so how to grow it? How do you plant seeds? How do you breed? According to the data, the tiger flower grows in the wild in the shady and wet places under the dense forest in the valley or in the rock crevices in the wet forest. Like high temperature, humid semi-overcast environment, strong cold resistance, not resistant to drought, avoid direct sunlight.

First, how to raise the tiger flowers?

Cultivation substrate

The cultivation substrate of Huyan Flower is the slightly acidic soil with loose fertility, rich organic matter, good air permeability, strong ability of water and fertilizer conservation but no stagnant water. generally, rotten leaf soil, peat soil and coarse sand were prepared at 2:1:1 and mature cow manure or chicken manure was used as base fertilizer.

Temperature and light

Tiger Yan Hua likes high temperature, humid semi-shady environment, strong cold resistance, avoid direct sunlight. The growth temperature is 17-30 ℃, can survive the winter safely above 5 ℃, and can withstand 0 ℃ low temperature for a short time. Special attention should be paid to shading in summer cultivation and management, and the shading rate should reach 50%, 70%, otherwise the leaves are prone to yellowing. It should be cultivated in greenhouse in winter, or other heat preservation measures should be taken.

Watering and fertilizing

Tiger Yanhua has higher requirements for moisture and is not resistant to drought. it is necessary to maintain high air humidity in the growing season, but to avoid stagnant water, otherwise it will cause rotten roots. It is usually watered once a day. Foliar compound fertilizer is applied once a week during the growing period, and it is appropriate to apply it thinly and more. More application of nitrogen fertilizer is beneficial to the green leaves, but the leaves are fragile. Do not spray water directly on the leaves when fertilizing, otherwise it is easy to cause leaf rot in the case of high temperature and lack of ventilation. In addition, it should be noted that the fertilizer demand of Huyanhua has a great relationship with the temperature. Generally speaking, more topdressing can be applied when the ambient temperature is higher, while less topdressing can be applied if the ambient temperature is lower.

Reproduction method

Tiger Flower can be propagated by sowing, plant division, cutting and tissue culture.

Note:

Common diseases of Flower of Tiger

In the growing season, especially when it is hot and rainy in summer, it is very easy to develop root rot and stem rot.

Common insect pests in tiger flowers

The main pests of tiger Yan flower are leaf beetle, nocturnal moth, lamp moth, snail, slug and so on, which easily engulf the leaves into holes.

Second, how to plant seeds?

1. Soil selection

To grow a flower, you must first choose a good substrate for it. When choosing the cultivated soil of Huyanhua, we should pay attention to its habits, so that the selected cultivated soil can make it grow better.

It likes the shady and wet growing environment, so it is best to choose the cultivated soil with certain moisturizing ability when selecting cultivated soil. This kind of culture soil can provide its growth environment with high humidity, which is beneficial to its healthy development.

The selection of decaying soil can provide it with more nutrients for growth and development and help it grow better.

Choosing the culture soil with better aeration ability as far as possible can help the seeds germinate as soon as possible.

2. Time of sowing

The flowering period of Huyan flower is in late November and the fruiting period is from March to May. After the fruit is ripe, seeds can be collected from it for planting. It's best to sow as you pick, and don't let the seeds stay in the outside world for too long.

First, if the seed is placed in the outside world for too long, it may reduce the germination rate of the seed. Second, because March to May happens to be the time for spring flowers to blossom, the seeds will have relatively good climatic conditions to develop and grow at this time.

3. The method of sowing

The first thing to do is to deal with the cultivated soil. Tiger Yan Hua likes fertilizer, so before sowing, it is necessary to add some organic fertilizer or animal manure as base fertilizer in the culture soil in advance to ensure adequate nutrition.

Choose a medium-sized flowerpot and put the treated culture soil into the flowerpot, about 9% full. Then water the pot with a kettle to ensure that the culture soil in the pot is moist enough.

Then put the seeds on the soil surface. Be careful to keep the distance between the seeds moderate, not too large or too small. If the species distance is too large, the distribution of grown plants may be too scattered, affecting ornamental; if the species distance is too small, it may make the growing plants too dense, and the resources in the basin may not be enough to support their healthy growth.

Then cover the seeds with a thin layer of soil. Be careful not to cover the soil too thick, just cover the seed 1cm.

Finally, put the planted seeds in a semi-overcast environment and water them on time and wait for them to germinate.

Third, how to reproduce?

1. The sowing of the propagation mode of Huyanhua

The seeds of tiger flowers are small and should be picked and sown. When sowing, it is appropriate to sow shallowly, and the sowing medium is made of 1 part of rotten leaf soil, 2 parts of peat soil and 1 part of fine sand. After disinfection and sieving, the basin surface is leveled, soaked with water and sowed evenly. After sowing, a shallow layer of fine soil or sand can be used to germinate in 30 days at the temperature of 18-25 ℃. After 2 months, the potted plant can be planted.

2. The ramets and cuttings of the propagation mode of Huyanhua.

Ramets and cuttings should be carried out when changing pots in spring. When changing pots, take out the mother plant carefully, do not break the leaves, and then cut the stolon into segments with at least 2-3 leaves in each section, which should be planted in pots after the incision is dried. Applying plant ash or charcoal powder to the shear wound can prevent the wound from rotting and improve the survival rate.

3. Tissue culture of propagation mode of Flos Artemisiae

The axillary buds of Huyan flower were used as explants and cultured on MS medium supplemented with 1.0mg / L BA and 0.1mg / L NAA under aseptic condition. The medium contains 2% sucrose, 0.6% Agar and 5.8 PH. The culture temperature was (25 ±2) ℃, the light time was 10 hours per day, and the illumination was 1100 lux (LX). The yellow-green callus grew within 1 week, and the cluster buds differentiated directly on the surface of the callus within 20 days. The cluster buds could proliferate rapidly when subcultured on the above medium. The cluster buds were transferred to 50% MS rooting medium with 0.1mg / L naphthalene acetic acid, and the roots could grow within 10 days. After one month of culture, the test-tube plantlets can be transplanted into the pot, and the survival rate of the seedlings is more than 90%.
