When should I raise autumn celery seedlings?

Celery can be planted all year round, spring celery should be selected to be more cold-resistant, early in winter, late in budding, vigorous growth, good quality varieties, summer and autumn celery should be selected heat-resistant, disease-resistant varieties. The overwintering celery should also choose cold-resistant, winter-strong, and late-sprouting varieties. After the seeds are sown and covered with fine soil and the arch is built, the celery seedlings grow, during which it is necessary to pay attention to the humidity and temperature inside, of course, the humidity is mainly based on "spraying", which is what the people in our village do, using spraying to replenish the water of the celery seedlings.

It prefers to grow luxuriantly in cooler and humid environmental conditions, and grows more slowly under high temperature and drought conditions, so celery seedlings are different in different temperatures, and the germination temperature of seeds is required to be within the range of 15 20 degrees, and the seedlings are planted in autumn, and the seedlings are sown from early June to mid-July, and planted from late July to late August. Since the autumn cultivation and sowing period is in the summer high temperature season, and the suitable temperature for celery germination is 15 25, more than 30 difficult to emerge, so seed treatment must be carried out.

Then rinse it with water, scrub it with water, rub off the outer epidermis, dry the moisture of the seeds, and promote germination at a temperature of 20 degrees below 22 degrees, if half of the seeds germinate to sow seeds, water the bottom of the foot before sowing, if the weather is hot, the topsoil is loose, and it is better to sow in the evening. About 150 grams of seeds are sprinkled per mu of seedbed. (It can be mixed with dry crushed fine soil, which is conducive to uniformity).

Then cover the medicinal soil, but not too thick, about 3 mm is enough. It is better to put on a 2-meter-high shade cloth if possible.

Therefore, when the temperature has risen, celery seeds are best soaked in water for 12-24 hours, mixed with a small amount of wet fine sand and placed in an environment of about 15 degrees Celsius for low-temperature germination, such as above the well (temperature and humidity are relatively constant), generally 5-7 days, and most of the buds can be sown after they are white. Sowing seeds 24 hours after soaking. Cover with soil centimeters.

After the emergence of seedlings and time seedlings, the seedling spacing is about 2 cm. Sowing in late April, no longer cover the film. After sowing, the seedlings should be covered with a shade net to facilitate moisture retention.

The specifications and requirements of the seedbed are the same as those for planting seedlings in spring.

Seedlings planted in spring are generally raised in greenhouses in January and February, planted in March and April, and harvested in May and July. Summer planting seedlings, generally sowing in March to May, need to soak seeds for 24 hours before sowing, after the emergence of seedlings and time seedlings, seedling spacing is controlled at about 2 cm, and when sowing in April, there is no need to cover the film, sowing seedlings before covering the shade net, in order to facilitate moisture. Autumn planting seedlings, generally in early June to mid-July for sowing seedlings, late July only late August planting, because the autumn sowing period is in the high temperature season, and celery seed germination temperature is between 15-25 degrees, more than 30 degrees difficult to emerge, so it needs to be planted for low temperature germination treatment.

In the north, seedlings are sown from June to early July, planted from August to early September, and harvested from October to November. In the Yangtze River Basin, the seeds are sown from early July to early September, harvested from October to December, and the late sowing is harvested from March to April of the following year, and the winter celery is harvested before the sprouting. It is cultivated in open fields in the Yangtze River basin and in the south, sown in September and November, and harvested from December to April.

It can be cultivated in protected areas in the north.

It should be at the end of summer, because at that time many celery seedlings will develop so that they can grow into finished products.

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.

Autumn celery can be raised in August.

Seedling raising method. 1. Seeds: Choose suitable seeds, 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, with an appropriate amount of Bika microbial agent, 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 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 believed to be familiar to everyone. It is a vegetable that everyone loves to eat. It is widely cultivated in our country, and July and August are a good time for celery seedlings. Let's take a look at how celery seedlings are grown? When is it good to plant seedlings? Let's take a look.

Soak the seeds for 24 hours before sowing. After seedling emergence and emergence, the seedling spacing should be controlled at about 2 cm. When sowing in April, there is no need to cover the film.

Cover with a shade net to help moisturize. Autumn seedlings are sown from early June to mid-July, and late July is only sown in late August. Since the autumn sowing period is in the high temperature season, the suitable temperature for seed germination is between 15-25 degrees.

It is difficult to emerge above 30 degrees, and low-temperature germination treatment is required.

Seedling method: 1. Seedbed selection, it is recommended to choose some seedbeds with high sand content and sufficient moisture. Plots with good permeability are low as seedlings. In order to make the seedbed fertile enough, you can sprinkle some farm manure and plough the soil evenly.

2. Seedlings, according to the local climate and market demand, select suitable varieties for planting, germinate the seeds, soak them in water before germination, and stir them fully when soaking. It is beneficial for plants to absorb enough water. After soaking for one day, the seeds can be placed in a temperature environment to speed up germination.

3. Key points of germination, during the germination process, the water should be changed in time and the seed situation should be carefully observed. Once the seeds appear white, the seeds are ready to be planted.

4. Maintain density, sowing density should be reasonable. Generally, 100 kg of seedlings per mu are required. When sowing, the seeds can be mixed evenly with fine sand, then spread and ready to use, and then covered with about a centimeter of fine soil after sowing.

5. Seedling management, after celery seedlings grow, they should be properly watered and fertilized. If weeds are found in the soil of the planting site, they should be removed in time. If the temperature is too high, the film should be removed in time.

Warm valley is, can also be properly covered with some plastic film, in order to facilitate the growth and development of seedlings. The above is an introduction to the time and method of celery seedling raising.

In fact, it is very important in a season like autumn, if you don't pay attention to this management, it is very likely that the dish will be necrotic, and there may also be poisoning, which is very scary in this situation.

In autumn, this time is to prepare celery seedlings, so that celery seedlings can grow well, so that it is very good.

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.

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.

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.
