What are the key points of marigold conservation management?

1. Soil: Choose soil with loose soil, rich nutrients and drainage properties.

2. Temperature: The temperature should not be 30 in summer, otherwise the flowers of the plant will wilt due to too high temperature; In winter, the temperature must be 5 so that the plants can survive the cold winter safely.

3. Light: Place the pot in a place with good sunlight, so that the flowering period of the plant can become longer; Growing in a place where there is no sunlight will increase the growth rate of the plant's leaves, affecting the appreciation of the flowers.

4. Fertilization: Give the plant some liquid fertilizer with a relatively low concentration every month when the plant is growing, but the fertilizer should not contain nitrogen, otherwise the leaves of the plant will also grow rapidly, affecting the blooming of the flowers of the later plants.

Marigold aliases: stinky hibiscus, longevity lantern, honeycomb chrysanthemum, stinky chrysanthemum.

Family: Asteraceae, Marigold.

Origin: Mexico and the Americas.

Marigold. Soil: Suitable for growing in fertile, loose and well-drained soils. Garden soil, humus soil and sandy soil can be used to prepare culture soil in a ratio of 5 3 2.

Fertilization: It likes fertilizer and is slightly resistant to barrenness. The more fat you have, the more flowers you have, but the plants are also easy to grow taller.

At the beginning of growth, combined with topping, top dressing and decomposing thin liquid fertilizer 2 3 times. After budding, potassium dihydrogen phosphate liquid is sprayed 1 2 times to the foliar surface, which is conducive to large flowers and bright color. After flower failure, the mixed liquid fertilizer can be applied 1 2 times.

Moisture: Prefer moisture, drought resistance, fear of water accumulation. Control watering during the growing season, keep the potting soil moist and slightly dry; It is advisable to keep the potting soil moist before and during flowering; Keep the potting soil dry during the summer heat, otherwise it will cause the plants to grow long, the stems and leaves to loosen, and the flowering will decrease.

Water accumulation in the potting soil should be prevented to avoid wilting and death.

Temperature: Warm, suitable for growth 20-30. Room temperature above 10 can safely overwinter.

Light: Likes to have a lot of sunshine. If there is not enough light, the stems and leaves are soft and slender, and the flowering is few and small.

Plastic pruning: Multiple topping can be carried out during the growing period to increase the branching and increase the number of flowers. After the flower fails, the residual flowers are cut off to promote the growth of new branches, and the flowering can be continued.

Breeding: 4 May sowing breeding.

Pest control: If a diseased plant is found, it should be uprooted and burned immediately. At the beginning of the disease, 50% carbendazim 1000 times can be sprayed, or 70% methyl tobuzin 1000 times sprayed.

When planting marigolds, you should choose some sandy soil, which is very good for air permeability and water absorption. You can choose some corrosive fertilizer, you can also choose some phosphorus fertilizer or nitrogen fertilizer, you can put it in a sunny place, and you can water it in the morning and evening.

Marigold cultivation to ensure sufficient light, suitable growth temperature between 20 30, winter to ensure that the temperature is more than 5. Choose loose and breathable soil for sowing and maintenance, water once a day in the growing season, and top dressing according to the frequency of once a month. After the marigold flowering period, the ruined flowers can be pruned in time to reduce the consumption of nutrients.

When cultivating this plant, it is necessary to choose loose and fertile and humus-rich soil, and secondly, we should also pay attention to watering and fertilization, the amount of watering each time is not too large, keep the soil moist, and do not water at noon, especially in summer, it is very easy to cause the roots to be burned, and secondly, we should also pay attention to fertilization, you can use liquid fertilizer, nitrogen fertilizer, farm fertilizer, but also to maintain good light, you can also top, promote more branches, so that you can bloom more, and you should also do a good job in the prevention and control of pests and diseases in the later stage, Then the marigolds will grow very well.

Marigold is a very high-quality annual herb, its plant is relatively short, and after flowering, it is a bright and dazzling color, and it is a common ornamental flower. However, for some novices in flower raising, if you want to plant marigolds, let's go with Uncle Gardener to find out.

1. Sowing. Marigolds can generally be sown in spring and summer, it likes warm climates, planting in these two seasons is more conducive to its growth, and the sowing time also determines its flowering time, so most of them will be sown in March and April to allow the flowers to open as soon as possible.

2. Watering. Marigolds should be watered more frequently during the growing season, but the amount of watering should not be too large each time. When watering, change the watering method according to the change of seasons, watering in the morning in summer and autumn, and watering at noon in winter and spring.

Most plants need a lot of water to maintain in the summer, because water loss is more severe when the temperature is higher. However, it is best to keep the soil dry during the high temperature period, because if there is too much water at this time, it is easy for the plant to grow, which will not only affect the plant shape, but also delay the flowering period or poor flower quality. So at this time, it is necessary to strictly control the watering.

3. Fertilization. Marigold should be moderately fertilized, a certain amount of basal fertilizer should be applied when planting, and liquid fertilizer should be applied once a month during the growth period, and nitrogen fertilizer should not be applied more calmly, so as not to grow and not bloom.

4. Pruning. After the marigold blooms, the residual flowers should be cut off in time, and the overly dense branches and leaves can be cut off, so that new branches can be germinated to promote more flowering. It can also promote the growth of marigolds in large quantities and aerial rooting.

When the aerial roots grow thicker, the marigold can be cut from the stem and replanted. It can also be re-pruned and pressed, but re-pruning is easy to affect the growth of plants, resulting in poor long branches and leaves, and poor flowering.

5. Pests and diseases.

Marigold has fewer diseases and insect pests, and the more common ones are spot blight, standing blight, powdery mildew, aphids, and leaf miners. Drugs can be used for prevention and treatment.

In the maintenance and management of marigolds, it is necessary to water them every day to ensure that the sedan chair will not be thirsty to death. It is also necessary to loosen the soil regularly, so that its roots have enough oxygen to make a group and thrive. It also needs to be exposed to light for one hour a day to get enough light to grow more vigorously.

Finally, nitrogen, phosphorus and potassium compound fertilizer needs to be applied during the change of seasons to enhance its nutrients.

Methods of conservation and management of aromatic marigolds1. Water regularly

Aromatic marigolds love water, and farmers need to water them twice a day, and each time the marigold roots are completely wet. But watering in summer can only be watered in the morning and evening, and watering at noon can easily lead to aromatic marigolds being sunburned. When watering in winter, avoid watering with cold water, which is easy to let the aromatic marigolds freeze to death.

2. Properly loosen the soil

Aromatic marigolds have a large root system and need more oxygen in the soil, so farmers need to loosen the soil for aromatic marigolds every month, so that the root system can get enough oxygen to grow. Farmers need to be careful when loosening the soil to avoid cutting off or damaging the marigold root system with a shovel that loosens the soil.

3. Sufficient light

Aromatic marigolds are sun-loving, and farmers need to let marigolds receive sunlight for an hour to allow marigolds to carry out sufficient photosynthesis. But farmers should not let marigolds bask in the sun at noon in the summer, which will cause marigolds to die. In winter, if there is no sun for a long time, the keeper can use a warm lamp to illuminate the marigolds.

4. Proper fertilization

Marigold growth is pressing, easy to grow, but still need to be properly fertilized, should be applied two months before the marigold flowering period nitrogen, phosphorus and potassium compound fertilizer, can also apply a small amount of urea. Urea fertilizer should not be applied too much, too much urea can easily lead to the wilting of longevity or rental chrysanthemum, and in severe cases, the marigold will be burned to death.

The planting of marigolds starts from the seed and every step is done, paying special attention to the transplanting time and fertilization.

First, the planting method of marigolds:

Material preparation: a number of marigold seeds, soft soil.

1. Seed germination: marigolds can be sown in spring and autumn. Seeds should be full and preferably new, and germinated in warm water in advance, which can improve germination rate.

2. Prepare the substrate: the substrate should be soft, breathable and well drained.

3. Sowing seeds into the soil: spray water on the surface of the substrate first, and then put in the seeds. After planting, it is covered with a thin soil to provide a warm, airy environment.

4. Timely transplanting: When the seedlings grow 3-4 true leaves, they can be transplanted, and watered thoroughly after planting.

2. Precautions for marigold planting:

1. Plot selection: no waterlogging, convenient drainage and irrigation, sunrise, plots with high organic matter content, avoid sandy land and plots with long residual effect period herbicides in the previous year.

3. Soil preparation and fertilization: 30 cubic meters of organic fertilizer, 300 kg of diammonium and 100 kg of potassium fertilizer per hectare are applied in combination with land preparation. Advocate autumn land preparation.

Planting methods and precautions for marigolds:1. Scientific sowing: Marigold seeds are sown in the soil in spring and covered with plastic film.

2. Supplement water and fertilizer: water the marigold once a day and apply farmhouse fertilizer once a month.

3. Control the light temperature: build an awning for marigolds in summer and move it indoors in winter.

4. Precautions: Marigolds should remove the flower branches at the top during the peak growth season.
