In the warmer south, can chrysanthemum be grown outdoors?

Chrysanthemum is a nutritious green vegetable, which is very delicious in both hot pot and stir-fry, so many farmers are now starting to grow chrysanthemum. But the quality of the cultivation is not the same, and this is because no good method is used. The following is an introduction to the planting method and time of chrysanthemum from the six points of planting time, planting method, water and fertilizer management, precautions, pest control and harvesting.

Chrysanthemum is usually planted in spring and autumn, but in some areas it is also planted in greenhouses in winter due to its delicious taste. In general, planting is carried out in February and May in spring, and in July and September in autumn. Because chrysanthemum has a special taste, which insects don't like, chrysanthemum is also a relatively healthy pest-free green vegetable.

The most common way to plant chrysanthemum is direct seeding, that is, planting directly in the soil according to a certain density, generally planting 3-4 chrysanthemums per 20 square centimeters. The second is to use seeds directly for planting, before planting the seeds need to be soaked in warm water for 7-12 hours, take out and dry in a cool and ventilated place to dry it can be evenly sprinkled in the field, and then cover the seeds with a thin layer of soil, after watering through.

Water and fertilizer management is the most important part of the growth process of chrysanthemum, as proper fertilization and watering will promote the growth of chrysanthemum. When the seeds germinate, they need to be watered in time, and generally choose a small amount of watering methods to ensure that the soil is moist. Generally, in the first 7-14 days of harvest, it is necessary to carry out topdressing in time, and the topdressing is mainly based on fast-acting nitrogen fertilizer, but it is necessary to pay attention to the amount of nitrogen fertilizer, and can not be used more, because excess nitrogen fertilizer will cause the growth of chrysanthemum.

Subsequent watering is done every 3-8 days to keep the soil moist.

In the growth process of chrysanthemum, it is necessary to pay attention to the situation of weeds in the field, and if there are weeds, they need to be removed in time to avoid weeds competing with chrysanthemum for nutrients.

Before planting chrysanthemum, the land can be turned deep to avoid overwintering of pests and diseases, so that the pests and diseases of chrysanthemum can be avoided at the root. However, it is still necessary to strengthen management when planting, and an appropriate amount of phosphorus and potassium fertilizer can be applied when fertilizing, which can improve the disease resistance of chrysanthemum.

There are two methods of harvesting chrysanthemum: one-time harvesting and phased harvesting. Generally, the one-time harvest is 40-50 days after sowing, and when the chrysanthemum grows to about 20 cm, it can be harvested close to the ground. Phased harvesting can keep 1-2 side branches for harvesting, and it can generally be harvested every 20-30 days.

Yes, there are a lot of chrysanthemums growing in the fields in many parts of the south.

Yes, depending on the temperature and humidity of the air required for the growth of chrysanthemum, the natural climatic conditions in the south are very conducive to the growth of chrysanthemum, and it can be planted in both seasons from spring to autumn.

OK. Before planting, the seeds need to be soaked in warm water for 7-12 hours, and after drying in a cool and ventilated place, they can be evenly sprinkled in the field, and then covered with a thin layer of soil on the seeds, and watered thoroughly.

Artemisia chrysanthemum, is less disease, less chemical fertilizer, easy to plant, good management methods of melons, fruits and vegetables, like our region can be planted all year round, but the key or autumn planting is dominant, spring is also planted, summer planting is less, because chrysanthemum is not heat-resistant. Artemisia chrysanthemum, as a kind of green leaf fast nature vegetables and fruits, because of the short growth period, can be picked 30-60 days after planting, the harvest period is flexible, can be planted in a year, the multiple planting index is very high, plus the planting of the reserve, can be sold all year round.

Like amaranth, it will grow and develop a batch after cutting, so the production amount is okay. The sowing time of chrysanthemum is divided into regional climatic conditions, for example, the southern region can be planted all year round, because chrysanthemum likes the temperature is suitable, but not heat-resistant, the temperature of the development environment is around 20 degrees, which is more suitable, and the continuous high temperature is not in place at 28 degrees The growth and development of chrysanthemum, ultra-low temperature 2 degrees can also grow and develop, and the seeds are very likely to germinate at 12 degrees, but the germination rate is very fast at 20 degrees.

Artemisia chrysanthemum is not too high for the light level, likes weaker sunlight, chrysanthemum belongs to shallow root vegetables and fruits, growth and development is faster, not waterlogged, do not need to be watered, often maintain the soil layer moist on it. The ambient humidity should be 80%, if you do not water for a long time, the soil will crack and cause the leaves and stems to become senescent, and the yield will be severely limited. The soil layer of chrysanthemum is generally not too high, and the loose and hypertrophied slightly acidic soil is most suitable for the growth and development of chrysanthemum.

Artemisia chrysanthemum is a leafy vegetable, its growth period cycle time is about 45 50 days, the amount of fertilizer is large, in order to promote its growth and development, the early application of foot fertilizer, the middle and late stage should be with the water top dressing fast-acting base fertilizer 3 4 times, each fertilizer application amount is, the fusion temperature of the number and the growth and development of the seedling plant flexible top dressing, the temperature is wet and cold, the liquid fertilizer concentration value is moderately thickened, the temperature is high, it is appropriate to apply lightly and even apply to.

1. Land preparation: planting Artemisia annua is generally carried out in February-April or August-September. First make sure the plot is soft and fertile.

2. Sowing and seedling: Generally, the direct sowing method is used to broadcast directly on the soil surface, cover the thin soil, and water. If the temperature is low, also cover with plastic film.

3. Timely seedling: When the seedlings grow 2-3 true leaves, the seedlings can be interspersed and weeded in time. 4. Fertilizer and water management

After the emergence of seedlings, watering and moisturizing, timely top dressing, to ensure that the fertilizer and water are sufficient. Artemisia can be grown in the north. Artemisia annua can be grown in the north, with small leaves, hard leaves, strong cold resistance, and a short growth period.

It can be planted in both spring and autumn. It takes about 20 days to raise the seedlings by putting them in warm water for about 12 hours to germinate, and the temperature is controlled at about 25. After the seedlings have grown three true leaves, they can be planted.

Artemisia chrysanthemum can be sown in the spring from February to May, and 7-9 in the autumn is also a good period. According to the actual situation of each city, choose a good sowing time, can not choose the sowing time according to the recommended time on the Internet, sowing early, low climate and temperature, slow seed germination is easy to rot, planting late, late seed germination is easy to affect the quality and yield of plants in the later stage, you can consult us in this regard.

Artemisia chrysanthemum can be cultivated in the north, the spring in the northern part of our country comes late, the sowing time should also be delayed, planted in the open air in the north, the spring is good in April and May, and the autumn is sown in August and September. In the south, spring comes early, so the sowing time is many days earlier than in the north.

Artemisia chrysanthemum can be grown in the north. Chrysanthemum chrysanthemum can be grown in the north, small-leaved type. Its leaves are hard, hardy, and have a short growing period.

It can be planted in both spring and autumn. The seeds are placed in warm water for about 12 hours to germinate, the temperature is controlled at 25, and the seedlings are raised for about 20 days.

Planting chrysanthemum mostly in spring, autumn and winter, it is suitable for growing in loose and fertile soil, before planting to the soil to apply foot fertilizer, 1500-2000 kg of organic fertilizer per mu, and then ploughing and raking flat furrowing. The seeds are sown or sown into the soil, properly watered after suppression, and mulched before excavation. When the seedlings grow to a height of 10 cm, they can be thinned.

1. Planting time.

Chrysanthemum has a good cold tolerance, so it can be planted in spring, autumn, and winter. Among them, spring sowing is mostly in March and April, autumn sowing is in August and September, and winter sowing is between November and December. Since it is not resistant to high temperatures, it cannot be planted in summer to avoid affecting the growth of seedlings.

2. Soil preparation and fertilization.

Like many plants, chrysanthemum grows well in loose, fertile soil, and good drainage can prevent the roots from being flooded. Usually before sowing, sufficient basal fertilizer should be applied, 1500-2000 kg of organic fertilizer per mu should be added, and 20-25 kg of diammonium phosphate should be added, which should be evenly sprinkled in the soil, and then ploughed and raked for furrowing.

3. Carry out sowing.

Chrysanthemum seeds are usually sown by spreading or strip sowing. After sowing, cover 1 cm of soil, after which it should be properly suppressed so that the seeds do not run away with the water when watering. If the planting time is earlier and the temperature is still relatively cool, in order to avoid the seedlings from freezing, it is necessary to cover it with plastic film before unearthing to keep it warm from the cold.

4. Field management.

When chrysanthemum grows to 10 cm, it is necessary to thin the seedlings, and the row spacing of the small leaves is 3-5 cm, and the large leaves should be kept at about 20 cm. At the same time, it is necessary to properly weed, watering should be sufficient, and keep the soil moist. Fertilizer is topapplied 10-15 days before each harvest, usually with potassium nitrate and urea.

Artemisia chrysanthemum is called basil and artemisia. Native to our country. The edible part is a tender stem, rich in nutrition, less fiber, excellent quality, unique in flavor, it is a variety of spices in vegetables, and it is also an indispensable refreshing dish in the fast food industry, hot pot city, buffet, etc.

Artemisia chrysanthemum not only has a pleasant flavor, but also is easy to cultivate, with fast growth and short cycle, and can be used for the cultivation of the front and rear stubble of the crops planted by the protection of the landlord, as well as the cultivation of intersets and insertions.

The whole plant of chrysanthemum has a special fragrant smell, which has a unique repellent effect on diseases and insects, therefore, pesticides are rarely sprayed, and it is an ideal pollution-free vegetable. It is a semi-cold-tolerant vegetable, which is conducive to its growth in an environment where it is cool and mild, and the relative humidity of the soil is kept at 70-80. In recent years, planting in protected areas in winter, spring and autumn has become more and more common.

It is generally harvested 40-50 days after sowing, and the growing period is extended to 60-70 days when the temperature is low.

1. Planting time is generally cultivated in spring and autumn. In the south, it can be cultivated in spring, autumn and winter.

2. The sowing method can be live broadcast, and seedling transplanting can also be used, mostly based on live broadcasting. Spread the seeds evenly on the culture soil, and after sowing, it is advisable to cover the soil with about 1 cm, water thoroughly, and keep warm and moisturize. Seedlings emerge in 4-5 days, and seedlings need to be thinned when they grow to 2-3 true leaves.

3. Planting chrysanthemum on the balcony, rooftop, or courtyard of the sowing utensils, the optional cultivation containers include flower pots, pots, professional cultivation boxes, styrofoam boxes, etc., and the depth of the tillage layer is 20 cm.

How to grow chrysanthemum.

1. Temperature: Artemisia chrysanthemum grows at a suitable temperature of 17-20 degrees Celsius, the weather is still relatively cold in early spring, and is accompanied by the phenomenon of cold spring, so after sowing, it is necessary to cover the furrow with plastic film or old shed film, and the surrounding soil is compacted to prevent cold and heat preservation, and the weather is warmer, and the seedlings are uncovered before the top film. When planting in protected areas over 25 degrees Celsius, open ventilation and let the air out.

2. Weeding between seedlings: when the seedlings grow to about 10 cm, the small-leaved species are pulled out according to the plant and row spacing of 3-5 cm, and the large-leaf species are pulled out according to about 20 cm, and weeds are eradicated at the same time.

<> chrysanthemum can be planted in the north. Artemisia chrysanthemum can be planted in the north can choose the small-leaved type of chrysanthemum, its leaves are harder, cold resistance is stronger, the growth period is short, can be planted in spring and autumn, the seeds are put into warm water for about 12 hours for germination, the temperature is controlled at about 25, the seedling needs about 20 days, and the seedlings can be planted after they have grown three true leaves.

Artemisia chrysanthemum, also known as Artemisia canopy, Artemisia sinensis, leafy vegetables eaten by stems and leaves, belong to the Asteraceae family; It has a unique fragrance and is a good ingredient for shabu-shabu and boiling soup. Artemisia chrysanthemum likes a cold environment, is not resistant to high temperature and drought, and the suitable growth temperature is 12 20, and the temperature is below 3. Artemisia chrysanthemum does not have too high light requirements, likes relatively weak light, chrysanthemum belongs to shallow root vegetables, fast growth, not waterlogging, do not irrigate, often keep the soil moist.

The humidity reaches 80%, and if you do not water for a long time, the plot will dry out and cause the stems and leaves to age.

Conventional cultivation of chrysanthemum is cultivated in the open field in spring, summer and autumn in the northern region, the sowing period in spring is 3 and 4 months, the autumn cultivation is sown in stages in August and September, and it can also be sown in early October. When cultivated in summer, due to the high temperature, slightly poor quality, and low yield, the northern alpine areas can use more summer-sown chrysanthemum, as a kind of green leaf fast-growing vegetable, due to the short growth period, it can be harvested 30-60 days after sowing, the harvest period is flexible, it can be cultivated in multiple stubbles in a year, and the multiple cropping index is very high, plus the cultivation of protected land, it can be marketed all year round. Like leeks.

On our side, chrysanthemum has only come to people's tables in recent years, because it belongs to a kind of vegetable of the same origin as medicine and food, so chrysanthemum itself has a special smell. It has strong cold resistance and is not resistant to high temperatures, so like our rural areas in Jiaodong, it can be planted in spring and autumn, with a crisp and tender taste and unique flavor. It is suitable for stir-frying, cold dressing, soup or shabu-shabu, and is a dish that is deeply loved by people.

Artemisia chrysanthemum is a shallow root herbaceous cold-tolerant plant, which is not resistant to high temperatures and does not have high requirements for soil, and is suitable for planting in the north and south of China.

The main planting seasons are spring and autumnThe minimum temperature of seed germination is about 10 °C, the optimal temperature is 15 °C 20 °C, the growth temperature is about 20 °C, the growth temperature is slow below 12 °C, and the growth is poor above 29 °C. It can be harvested in 40-50 days from sowing.
