How to propagate, how to propagate, how to propagate / sow / cuttage

Qianrihong is a kind of flower with high ornamental value, and it is cultivated in many areas of our country. With more people breeding, people are more concerned about its reproduction, so how to breed it? What are the breeding methods of thousand-day red? Next, the editor will take you to learn about it.

First, how to breed thousand-day red

Second, the breeding method of thousand-day red

Sowing and reproduction

1. Sowing time

The seeds of thousand-day red are generally harvested in September-October every year, stored after harvest, and sown in April-May of the following year. The temperature of this period is more suitable for the growth of thousand-day red, and the survival rate will be relatively high.

two。 Soil selection

In the breeding method of thousand-day red, the choice of soil is a very important step, generally we can choose more fertile humus, because this kind of soil has good drainage and air permeability, which can make thousand-day red better absorb nutrients.

3. Sowing method

After doing the pre-treatment, we can sow the seeds. Before sowing, we need to soak the seeds for 3-5 days before sowing, so that the seeds can germinate more easily. After soaking, we can evenly sow the seeds on the soil surface, and then cover them with about 2-3cm of soil to water. When watering, we should pay attention to watering thoroughly, and then the seedlings can emerge in about 10-15 days.

Cuttage propagation

1. Cuttings selection

Before the cuttage propagation of Qianrihong, we first need to choose cuttings, that is, the branches of Qianrihong. Generally, it is best to choose the branches with strong growth, so that the survival rate will be very high. It is generally difficult to survive if you choose branches that look delicate.

two。 Cutting method

Among the propagation methods of Qianrihong, cutting propagation is a more commonly used method. when cutting, we can first use chopsticks to insert a hole in the soil, and the cuttings can be watered by pressing the soil into the hole. About 20 days after watering, you can take root.

How to propagate, how to propagate by cuttage

Thousand-day red how to breed station, thousand-day red reproduction methods are sowing reproduction and cutting propagation, flower friends can choose the appropriate thousand-day red breeding methods through their own preferences and conditions for reproduction, the following respectively sort out thousand-day red sowing propagation methods and thousand-day red cutting propagation methods, hoping to help flower friends.

Sowing and propagation method of thousand-day red

The growth of thousand-day red seedlings is slow, so it should be sowed in the greenhouse in advance in the first ten days of March. The suitable temperature for sowing is above 20 ℃ and the germination is better. The emergence of seedlings is slow because there is a fine layer of white cilia on the outside of the seed.

1. Seed soaking

Soak the seeds in cold water for 2 days, or soak the seeds in warm water for 1 day. After soaking the seeds, wrap them with gauze, place them in a shallow basin, drench them with clean water twice a day, put them in a warm place, and germinate after about two weeks.

3. Seed sowing

After germination, it is sown in the basin, covered with shallow soil, and then covered with glass to keep warm and moisturizing.

4. Transplanting

Wait for the seedlings to come out once and then transplant. Apply appropriate amount of base fertilizer to the ground or pot before transplanting.

5. Maintenance and management after planting.

During the growth period should not be too much watering and fertilization, otherwise it will cause stems and leaves to grow only, flowering rare. In order to dwarf the plant, the heart should be picked once at the seedling stage, and the residual flowers should be cut off in time to promote the germination of new branches so as to make them blossom again.

Propagation method of thousand-day red cuttage 1. Selection of robust branches and cutting methods

From June to July, the robust shoots should be about 4~6cm, that is, 3 to 4 nodes, and the internodes inserted into the soil layer should be cut off to reduce leaf surface water evaporation. Insert it into the sand bed, control the temperature at 20 ℃ ~ 25 ℃, and transplant it to the pot 18-20 days after insertion. If the temperature is below 20 ℃, the days of rooting will be delayed by 5-7 days. For example, the rooting effect of cuttings treated with "Root Sun" rooting agent will be about 10-12 days faster.

It can be seen from the above table that the effect of cuttings treated with "Root Sun" rooting agent is significant, and it can be transplanted 7-8 days after cutting. However, the cuttings without any drug treatment can not be transplanted until about 18-21 days after cutting. Therefore, the author uses "Root Sun" in cuttage propagation in recent years, and the seedling growth time is short, which can greatly save manpower and material resources, and the survival rate can reach more than 95%.

2. Management after thousand-day red plug a, moisture and humidity control

The nursery bed should be watered before cutting. the aim is to make the cuttings undamaged and improve the survival rate. The depth of cuttings can not be too deep, and one Internode can be buried. After cutting, water should be watered in time to make the cuttings close with the soil. After normal watering, keep the soil moist or spray once or twice a day for 1 minute or 2 minutes a day, or once a day.

B, light exposure

The seedbed should be set in a covered place, with a shading rate of 80% to 90% in summer and about 70% to 80% in spring and autumn.

C, temperature control

The optimum temperature for rooting of cuttings is 20 ℃-25 ℃. When the temperature is lower than 18 ℃, it has a certain effect on rooting and the survival rate is low. If the temperature is below 10 ℃, the cuttings will be damaged by freezing. If you want to propagate cuttings, you must have greenhouse equipment.

3. Management after transplanting into pot, transplanting of flowers and seedlings

When the root system of cutting seedlings grows to 0.5~1.0cm, it can be transferred to pot. If the pot is too late, the seedlings will grow weak in the sand without nutrition, which will affect the growth and development in the future. When the sowing seedlings grow 3-4 true leaves, they can be transplanted into the pot. Tile basin should be selected for planting, and the drainage performance of tile basin is better than that of rubber basin.

B, seedling illumination

Thousand-day red is a positive flower, in addition to the seedling stage, should not be direct sunlight, a week after the pot can grow in a sunny environment. Sufficient light is conducive to the formation of round, low plant shape, we must pay attention to maintain sufficient row spacing in the process of cultivation, so as to avoid crowding each other, lack of light and poor plant shape.

C. Germination temperature control

After germination, the seedlings can continue to grow at a temperature of 20 ℃ or more. Qianrihong is a kind of heat-resistant species, suitable for spring sowing autumn flowers, but not cold-resistant, generally do not use autumn sowing, otherwise heating in winter, the cultivation cost will be very high

Propagation method of thousand-day red how to sow thousand-day red

Qianrihong is a kind of plant with strong vitality, its stem is tall and straight, and there is a more gorgeous flower at the top of the stem. It is different from ordinary plants in that its flowers are everlasting, so they are highly ornamental and deeply loved by people to plant.

Breeding method of thousand-day red

1. Sow and reproduce. The annual spring and summer season, about April and May, is the most suitable climate for breeding thousand-day red. Sow a proper amount of red seeds evenly in a relatively large soil environment, and flower friends who have the conditions can directly open up an open space to sow seeds in the courtyard. I believe you are already very proficient in the basic methods of soil loosening and sowing, so I won't repeat them here. Remember to disinfect and mix the seeds before going into the soil, which can effectively improve the germination rate, so that they can be transplanted when they reach a certain height in June.

2. Cutting propagation method Summer is the most exuberant season for thousand-day red growth, and it is also the most suitable season for cutting. Cut some of the relatively strong branches of the plant about 5 centimeters in length, remove the leaves from the part of the branches to be inserted into the soil, and then insert the branches directly into the soil. The average temperature of about 20 degrees is most conducive to root germination and growth, and the root system can grow long enough to transplant it into a flowerpot in about three weeks, so a new thousand-day red plant is born.

How to sow the thousand-day red

1. Soak the seeds with thousand days of red. Find a shallow container, place the seed in it, pour it into the water, and just pass the seed. Soak in cold water for 2 days or in warm water for one day. The purpose of soaking seeds is to soften the epidermis of seeds and improve the germination rate.

2. Red seeds sprouted. After soaking the seeds, wrap them in gauze, put them in a shallow basin, or use paper towels. Drench in clean water once or twice a day and put it in a warm place with scattered light. After two weeks, you will see small white buds, and at this time you can sow seeds.

3. The sowing method of thousand-day red. After germination, it is sown in the basin, covered with shallow soil, and then covered with glass to keep warm and moisturizing. After all the seedlings have grown, pull out the thin seedlings. The red seedlings grow slowly and will accelerate after June. When the seedlings grow 7-8 leaves, move the seedlings to other flowerpots or containers.

4. Red sowing for thousands of days. Post-maintenance growth period should not be too much watering and fertilization, otherwise it will cause stems and leaves to grow and flowering sparsely. Pay attention to replenish water when it is hotter in summer, you can maintain the flowerpot in the open air and pay attention to the rain.

The field management of thousand-day red

1. Plastic surgery. When the seedling was high and 15cm, the heart was removed once to promote branching. In the future, it can be decided whether to carry out the second heart removal according to the growth situation. When shaping and pruning, attention should be paid to the circle shaping of the plant, so that the thousand-day red has a higher ornamental value. When the plant is formed, the flowering period can be effectively controlled by coring the branches.

2. Watering. Thousand days of red light tide, dry soil environment, more drought-resistant. Therefore, when the seedlings grow new leaves, it is necessary to properly control watering; when the plant flower bud differentiation, appropriately increase the amount of water, in order to facilitate the normal growth of flowers.

3. Fertilization. In addition to using rotten chicken manure as base fertilizer during colonization, rarefied liquid fertilizer rich in phosphorus, potassium and potassium should be applied every half a month in the vigorous growth stage.

Disease control of Qianrihong

1. Leaf spot disease. Prevention and treatment: remove the leaves with spots in time so as not to infect others. Increase the application of phosphorus and potassium fertilizer, control the content of nitrogen fertilizer and enhance the disease resistance of the plant. Early stage of the disease timely spraying to control the disease, spraying agents can go to the florist for consultation, the commonly used flower protection god, carbendazim can. Once every 15 days, spray 2 or 3 times continuously.

2. Sudden collapse disease. Prevention and treatment: in the initial stage, plant paralysis is not serious and slight lodging, timely spraying methyl topiramate solution, to a certain extent, can be alleviated. If the stem of the plant has collapsed and begins to rot, pull out the plant in time, it cannot be saved. Spray fungicides after removal to avoid infecting other plants.

3. Virus. Prevention and control methods: control diseases and insect pests, once insects are found, clean up in time. Reduce plant wounds and avoid artificial wounds on leaves in the process of maintenance, because our conservation environment is said to be clean, but it is actually full of bacteria to avoid the invasion of viruses from wounds.

The propagation method of thousand-day red is similar to that of general flowers and plants, and it is more common to sow seeds and cuttings. When planting, we must do a good job in seed selection and choose an appropriate time to carry out. Field management should be carried out in the later stage of planting, only in this way can the thousand-day red grow better.
