How are celery seedlings raised? When is it better to raise seedlings?

Celery seedlings need to be selected, soaked in water for a period of time, and then germinated after being fished out. The planted sand bed must be loose and well drained, and the seeds should be mixed with sand and then sown so that they can be planted in early September. There is not much limit to the seedling raising time, the south can be all year round, the north is best selected in spring and autumn, July is the most suitable.

Seedling method: 1. Seeds: select suitable seeds, and then soak them in cold water for about 24 hours 6 hours before sowing, then slowly scrub them and replace them with fresh water.

After that, take it out and wrap it in gauze, put it in the environment of 15 years to germinate, and wait until the seeds begin to show white before sowing.

2. Seedling: The planted sand bed must be loose and the drainage effect should be good. Its seeds are very small, often some seeds are glued together, it is difficult to separate, and it is difficult to sow evenly, so it can be mixed with some fine sand, mixed and then sown in, covered with a thin layer of soil, the thickness can not exceed 1cm.

3. Dense planting: In early September, it is a good time for planting, and it can be reasonably planted to ensure a good temperature, preferably around 15-20.

The first point of celery seedlings is to use the greenhouse buckle out, the second year should be in March and April when the seedlings are better, and the celery will grow very strong, the third point of the seedlings should pay attention to the temperature is good.

Under normal circumstances, germination treatment will be carried out in advance to ensure the survival rate of seeds, and the seeds can be evenly sprinkled on the soil, keep the temperature at about 20, give enough light, and water; I think it's better to raise the seedlings in March, so that the temperature can be guaranteed and strong light will be avoided.

It is necessary to mix the seeds and sand in advance for seedling cultivation, and the cultivation methods are different in different places, and the varieties are related.

Seedlings can be raised in either spring or autumn.

Key points of celery planting management methods:

1. Diseases. Celery seedlings after excavation are susceptible to diseases such as rooting, cataplexy and blight. Root is mainly a disease caused by low sowing ground temperature, belongs to physiological diseases, to prevent and control mainly from the control of sowing temperature, after the seedlings are unearthed, the temperature should be reasonably controlled according to the climatic conditions, when the temperature is too high, remove the plastic film and covering, build a shade net, remove the shade net and plastic film when the temperature is moderate to ventilate the seedbed, let the seedlings shine into the sun.

Cataplexy and blight are two diseases that are easy to occur at the seedling stage, and the harm to celery seedlings is also great, and the disease conditions are related to high temperature, high humidity, overwatering, excessive seedling density and poor ventilation.

2. Water and fertilizer management.

Celery seedling water fee manager is very important, do not over-stir, before sowing after watering basically no more watering, seedlings unearthed according to the drought of the soil for a small amount of watering, it is recommended that the watering time in the morning, the temperature will be reduced in the afternoon, the growth of celery seedlings is not good. To also top dressing, it is recommended to use water-soluble fertilizer with soil chef effect, which has the effects of rooting, fruit expansion, quality improvement, yield increase, anti-premature aging, etc., with fast effect and good effect.

Celery can be grown all year round, and the yield and quality of celery grown at different times will vary. The planting time of spring celery is between March and April, especially in March, when it is best planted and can be harvested after about three months, and the celery at this time can be said to grow better and the yield is relatively high. Although there is celery in summer, it is not planted much, because the weather is very hot in June and July, so the survival rate is not high, and the growth is not good, which affects the yield.

Autumn celery and winter celery are better, and celery itself likes to grow in colder places, so this season is especially suitable for growing celery.

After planting celery seeds into the soil, water them in time to ensure sufficient sunlight and maintain a constant temperature, so that the seedlings can be raised quickly, so that the celery seedlings can grow rapidly and form a good growth rate. The vaccine is the best in spring, summer and autumn every year, and it is basically kept in March, April, June and August every year.

After the seeds germinate, they are transplanted into the soil and watered in time to ensure sufficient sunlight, so that the best seedling state can be achieved. Seedlings are raised in the spring and summer of each year to achieve the best survival rate.

The celery seeds are selected and then germinated, and only after the seeds have germinated are planted. In the spring, the vaccine is better.

How are celery seedlings raised? When is it good to raise seedlings? With the rise of people's attention to health and health craze in recent years, celery, which is rich in protein, B vitamins, carbohydrates, carotene, sodium, iron, phosphorus, calcium, and has the ability to calm liver heat, ischemia, clear the intestines and appetize, low blood pressure and lower blood pressure, cool blood and stop bleeding, functional determination, brain and soothe the nerves, remove annoyance and detoxification, detoxification and release of lung vegetables are very popular, so when to grow vegetables?

Let's take a look.

<> spring celery is sown in North China in January, seedlings are raised from January to March, planted in March and April, picked around June, and sown in March in the Yangtze River Basin. If the seedlings are sown too early, the seedlings are easy to pull moss too early through low temperature vernalization, and sowing too late, resulting in a high temperature environment in the later stage, which will affect the quality and yield of spring celery. Seedlings are sown in April and May, and can be planted on bare ground after emergence, planted in June and July, and picked at the end of August.

Autumn celery is sown in June-July, transplanted in August-September, and harvested in October-December in northern China. In the Yangtze River basin, autumn celery is sown from July to September and picked from October to December. Autumn celery sown after September is harvested in March-April of the following year.

Winter celery is grown in greenhouses in the north and is not time-requires. In the southern part of the Yangtze River basin, sowing is carried out in the open air from September to November, and harvesting is carried out from December to April next year.

After the disinfection treatment, put the seeds into the constant temperature water at a temperature of 48 and stir for 30 minutes, take them out and soak them in cold water after 24 hours, scoop out the seeds and rinse them, drain the water, wrap them in gauze and wet towels, put them in a place with a temperature of 18 20, and sow them when there are 30 50%. The seedbed should choose a field with good water and fertilizer performance, convenient drainage, fertile and loose soil, apply 25 kg of well-rotted organic fertilizer, 50 grams of carbendazim and 100 grams of nitrogen, phosphorus and potassium compound fertilizer per square meter, and cultivate the soil for the field, as a furrow field with a wide meter, a field width of 1 meter, and a deep meter of ditch. Spread a thin layer of soil on the furrow surface with water.

Sprinkle the seeds evenly, cover the soil up to centimeters, spread a thin layer of straw on top of the soil, keep it moist.

To raise seedlings in the greenhouse, the soil selects high sand content, sufficient water, permeable land, the seeds are germinated in advance, soaked in water, soaked for a day to timely germination, timely water change, sowing density per mu generally needs 100 kg of seedlings, after planting, to cover about centimeters of fine soil, and then watering and fertilizing. The specific time should be selected around January to February.

First, the celery seeds are sprinkled in the shallow soil layer, and then the seedlings are raised by watering and mulching, generally around March.

Celery can be sown with seeds and opened in seedling trays, and I think it is best to raise seedlings in the spring.

First, the seedling method.

1.Seeds: Choose the right seeds, soak them in cold water for about 24 hours before sowing, then slowly scrub them and replace them with fresh water.

After that, take it out, wrap it in gauze, put it in an environment of 15 years to germinate, and wait until the seeds turn white before sowing seeds. 2.Seedlings:

The planted sand bed must be loose and the drainage effect should be good. Its seeds are very small, and some of the seeds stick together, and it is difficult to separate them and sow them evenly. So you can mix some fine sand, and then sow a thin layer of soil, the thickness should not exceed the dense planting:

The beginning of September is a good time to plant seeds. Dense planting can be carried out reasonably, and the temperature of one is closed, preferably around 15-20.

Second, the seedling time.

Adaptable, there is not much time limit for raising seedlings. It can be grown all year round in the south, but try to avoid the summer months. In the north, it is best to choose spring and autumn, sowing is very suitable, and July is the most suitable. At this time, the temperature is high, which is conducive to germination, and the humidity content in the air is high.

The method of sowing celery seedlings is to select the seeds first, soak them in water for a period of time, and then take them out for germination. The planted sand bed must be loose and well drained.

Celery, a plant in the family Apiaceae. There are two kinds of water cress and dry celery, which have similar functions, and the medicinal use is better than dry celery. The aroma of dry celery is stronger, and it is also known as "parsley".

Celery, also known as celery, celery, parsley, parsley, medicinal celery, and wild coriander, is in the genus Celery in the family Apiaceae.

One- and two-year-old herbaceous plants. Native to the swampy areas of the Mediterranean coast, it has been widely cultivated in countries around the world.

Celery cultivation in China began in the Han Dynasty and has a history of more than 2,000 years. At first, it was only cultivated as an ornamental plant, and later used for food, and after continuous domestication and cultivation, it formed a slender petiole celery cultivated species, that is, Chinese celery. This celery is widely distributed in various parts of China, and Zunhua in Hebei, Weixian and Huantai in Shandong, Shangqiu in Henan, Jining in Inner Mongolia and other places are famous production areas of celery.

It was used by the ancient Greeks and Romans for seasoning, and in ancient China it was also used for medicine. The form of ancient celery was similar to that of today's wild celery. In the late 18th century, celery was cultivated to form large, juicy, fleshy erect petioles.

The edible part is its petioles. Celery is characterized by being gluten-rich, but has been bred into some less-gluten varieties, famous ones such as Pascal.

During the European Renaissance, celery was often used as a vegetable or as a condiment to soups and vegetable stews. In the United States, raw celery is often used as an appetizer or salad.

The planting time of celery is to germinate, sow and raise seedlings in June and early July in the north, plant in August and early September, and harvest in October and November. In the Yangtze River Basin, the seeds are sown from early July to early September, harvested from October to December, and those sown late are harvested before the draw in March and April of the following year.

<> celery is mainly divided into three types: spring celery, summer celery, and autumn celery. Spring celery is generally planted in March-April, summer celery is generally planted in April-May, and autumn celery is generally planted in July-August. Celery seeds should be selected before planting, and the seeds can be soaked in cold water for about 24 hours before sowing; The land on which celery is grown must be loose and well drained.

1. When will celery be seeded and planted?

1. Spring celery is usually raised in January and February, and planted in March and April; In summer, celery is generally raised in March and May, and planted in April and May. Autumn celery seedlings are raised in June-July and planted in July-August.

2. Before planting, the seeds must be selected for suitable seeds, and the seeds need to be soaked in cold water for about 24 hours before sowing, and then the seeds must be slowly scrubbed and replaced with fresh water. Then take out the seeds, wrap them in gauze, and put them in an environment of 15 to germinate, and wait until the seeds begin to show white, and then you can sow them.

3. The sand bed for celery seed planting must be loose and the drainage effect should be good. Because the seeds of celery are very small, there are often some seeds that stick together, which is particularly difficult to separate, and can be mixed with some fine sand when sowing, and then sown after mixing, after sowing, it should be covered with a thin layer of soil, and the thickness should not exceed 1cm.

2. How to raise and transplant celery

1. It is difficult for celery seedlings to emerge, so the sandy loam soil with relatively high terrain, convenient drainage and irrigation, and fertile soil should be selected as the breeding ground for planting. During the planting period, it is necessary to apply enough rotting base fertilizer, during the seed budding period, you can use the wet sowing method, and build a shade shed on the seedling furrow to prevent heavy rain and strong sun, and the transplanting must be carried out in the existing environment without destroying the celery, and the environment after transplanting should be similar to before.

2. After the seeds are sown, the soil must be evenly covered, the seedlings must be kept moist, generally every 1-2 days in the morning and evening, until the seedlings come out, in the spring and autumn when sowing can not be set up shade shed, but to water a small water frequently, in order to facilitate the emergence of seedlings.

3. In the early stage of seedlings, there is generally no need to top dressing, if the growth is found to be weak, foliar top dressing can be used after the seedlings, such as potassium dihydrogen phosphate and urea mixed fertilizer, which can promote the growth of seedlings. Top dressing should master the principle of a small amount many times.
