Introduction to the propagation method of butterfly flower

Butterfly flower is now a very famous early spring flower, called cold tolerance, the time of sunlight has a greater impact than light intensity, and is often planted as a biennial plant. Some flower friends will plant butterfly flowers at home and like to breed themselves. in general, butterfly flowers can be propagated by means of ramet, cutting and sowing.

Butterfly flower

Butterfly flowers are propagated in early winter or early spring dormancy. Firstly, the old plant of butterfly was dug up from the soil, and the rhizome was cut into a single plant with 3 buds in each section, which could be planted after the cut to dry. The leaves of more than 30 cm of the plant can also be cut off after flowering and cut into a clump of 3 plants every 2 May. this method of split propagation of butterfly flowers can not blossom until the third year.

The cuttage propagation of the butterfly flower is often carried out in spring. The rhizome of the butterfly flower is cut into cuttings of 6 ℃ 8 cm, and then inserted into a sand bed with a temperature of 20 ℃ to expose the top 1-1.5cm of the butterfly flower. After watering enough water at the beginning, pay attention to maintaining a certain humidity in the sand bed. After about 2 weeks, the butterfly flower can germinate to form an independent new plant, and when the new plant pulls out 2 mi 3 new leaves, it can be planted.

The method of sowing and propagation of butterfly is often when the top of the butterfly capsule is ripe and cracked, the seeds are collected immediately and sprouted in the same year. The dormancy state of butterfly flower was broken by refrigerated seeds and germinated 10 days after planting. The seedlings of butterfly flowers must bloom for 3-4 years.

Introduction to the breeding methods of butterfly flower and its pest control methods.

The butterfly flower is rich in color and variety, and it is more and more loved by the majority of flower friends. Butterfly flowers are huge and beautiful when they bloom. Butterfly flowers are very suitable for domestic use and are good ornamental plants. Today, I will come to you to learn about the reproduction and pest control of butterflies.

Common diseases

1. Bacterial soft rot

Symptom

It is mainly caused by European bacteria, which causes the tissue or organs of butterfly flowers to rot, mainly harming plant organs, tubers and stem bases, and so on. During the onset of the disease, the damage is serious, and the soft rot caused by bacteria usually produces indole due to the decomposition of protein glue by miscellaneous bacteria.

Prevention and cure method

1. Disinfect the seedlings

two。 The pots and utensils for cultivation should be sterilized.

3. The method of cultivation should be suitable.

4. Use drugs for prevention. Can choose agricultural streptomycin, chloramphenicol and other anti-bacteria and other drugs, the concentration does not need to be very high.

two。 Leaf blight

Symptom

The high incidence period of butterfly mosaic leaf blight is from July to October every year, and the incidence of plant leaf blight is more serious. Leaf blight will survive the winter on the diseased leaves of butterfly flowers, and when the temperature is suitable in the following year, it will spread to butterfly flowers through wind and rain.

Prevention and cure method

1. In the autumn, the diseased leaves will be completely removed and concentrated a little to prevent harm to butterflies in the coming year.

two。 Strengthen the cultivation and management of butterfly flowers to control the occurrence of diseases.

3. It can be sprayed every ten days in the areas where the disease is more serious in the growing season, and several consecutive sprays can effectively prevent and cure it.

Common insect pests

It is often caused by the bite of larvae of night moths, snails and slugs. The roots of butterfly flowers are usually endangered from June to August every year, and the unripe organic fertilizer often induces adults to lay eggs.

Prevention and cure method

It can be sprayed with 40% omethoate EC 1000 times. Or spray with 3% lime water in the evening.

The above are the common diseases and insect pests of butterfly flower and its prevention and control methods. I hope it can be helpful to the majority of flower friends. Please continue to pay attention to succulent flower beds and learn more about flower conservation.

Introduction to the culture methods of domestic butterfly flowers and matters needing attention in culture.

The butterfly flower is rich in color and variety, and it is more and more loved by the majority of flower friends. Butterfly flowers are huge and beautiful when they bloom. Butterfly flowers are very suitable for domestic use and are good ornamental plants. Today, I will tell you about the breeding methods of butterfly flowers.

Culture method

1. Soil

Butterfly flowers like wet, well-drained, humus-rich, slightly alkaline clayey soil.

two。 Watering

Irrigate the butterfly flower once after planting, and then replenish water according to the actual dry and wet soil. Butterfly flowers are watered once a week during the open-field cultivation period, and the amount of water gradually decreases with the decrease of air temperature. it is generally advisable that the soil is slightly dry and do not make the soil stagnant or too wet for a long time, so as to avoid rotting roots or diseases.

3. Sunshine

Butterfly flowers like sufficient sunlight, but also slightly shady, suitable for pot culture, can be cultivated in the open field. Strong adaptability, general normal management will be able to grow vigorously.

4. Fertilizer application

Butterfly flowers should be fertilized with base fertilizer before planting. Before sprouting and growing in spring, butterfly flowers should be applied 1-2 times of mature thin cake fertilizer or compound flower fertilizer, and it is best to apply liquid fertilizer again after flower withering.

5. Temperature

The suitable temperature for cultivation is 25-28 ℃ in the daytime. It is also seen that the frontal temperature is 18-20 ℃, and the seedlings should be raised to about 23 ℃ at night. In this temperature environment, butterfly flowers grow almost all the year round, especially the seedlings grow rapidly, and the seedlings removed from the test tube can blossom in about 1-2 years.

6. Humidity

The humidity of the original place of the butterfly flower is relatively high, so Aipei butterfly flower should create an environment with high air humidity. Generally speaking, humidity should be kept at 60-80% throughout the year. Since the climate is dry in spring, autumn and winter in the vast areas of the north, we must try to improve the air humidity of the cultivation environment. We can increase the humidity of the local environment by sprinkling water on the ground, platforms, walls, etc., several times a day, or a small amount of waterlogging on plant pages.

7. Light

The cultivation of butterfly flowers should have a good shading condition when exposed to strong light. Although the leaves of butterfly flowers are too wide and thick, and abundant water is stored on them, the stratum corneum and drought-resistant structure on the leaf surface are relatively poor, so once they encounter direct sunlight, they lose more water, or are not replenished in time. Leaves are prone to sunburn.

8. Diseases and insect pests

The common diseases of butterfly flower are rust, soft rot and so on. 25% trimethoprim 400 times solution can be used to control the rust at the initial stage, and Bordeaux solution can be used to control the soft rot. The pest of butterfly flower is Spodoptera litura, which can be controlled by root irrigation with 1200 times solution of trichlorfon.

Matters needing attention

1. In winter and spring in North China, it is often sunny and rainy, so proper shading is needed at this time.

2. When the summer sun is strong and the temperature is too high, the sunshade net or bamboo curtain should be covered outside the greenhouse glass to play the dual role of greenhouse cooling and sunshade, and the amount of sunshade should be more than 60%. You only need to cover about 40% in the fall.

The above are the breeding methods and matters needing attention of butterfly flowers I have sorted out. I hope it can be helpful to the majority of flower friends. Please continue to pay attention to succulent flower beds and learn more about flower conservation.
