How to grow celery at home? How to grow celery

Due to the strong adaptability of celery, the period when it needs to be protected and planted is generally in winter. In winter, spring and late autumn, it can be planted alone or interplanted with cucumbers and tomatoes.

Wintering in solar greenhouses: seedlings are raised from June to August, planted from August to October, and harvested from December to April.

Improved Yangqi winter and spring celery: jade noodles between late August and early September, planted from mid-October to early November, harvested from April to May.

Celery is an umbrella-shaped plant, eating more celery has a certain effect on preventing high blood pressure and some cardiovascular diseases, it is originally produced in the Mediterranean region and the Middle East. In Europe, celery was usually eaten as a vegetable, and in many cases it was also used as a chat or stew. In the United States, celery was usually used as an appetizer as well as for salads.

Celery prefers a cold place, moist and then grow, the seed germination can not be lower than about 4 degrees, the most suitable temperature is about 15 degrees to 20 degrees, germination below 15 degrees will be delayed to a certain extent, more than 30 seeds do not germinate, but the seedlings are more heat-resistant, at about 5 degrees is a relatively low temperature, at this time the plant will maintain a certain green plant.

The seeds of celery are relatively small, the strength of the young shoots will be slightly weaker, and the emergence speed of the seedlings will generally be a little slower. When sowing is done at high temperatures, the soil is not conducive to the emergence of seedlings, but the seeds are easier to germinate in the presence of light. Its seedlings grow a little slowly, the seedling period is longer, and it is easier to harm manual weeds, so it is necessary to strengthen certain management when raising seedlings.

In the autumn of cultivation, it is more suitable for the weather of celery growth, and at this time, you can use the land or tent to breed and achieve **. In general, spring cultivation is mainly concentrated in the greenhouse, and the seedlings are planted in March or April, and the seedlings are harvested in May and sown in autumn, and the harvest can be achieved around October.

Before planting, it is necessary to pay attention to certain management, in fact, celery seedlings are still more difficult, to choose some higher terrain in order to better ensure a certain seedling, in the case of relatively high terrain, drainage will be more convenient, at this time the soil is also relatively loose, fertile suddenly Brother to carry out a certain cultivation, at this time if the soil is not good to carry out a certain amount of fertilization, this time can reach a certain speed of seedling, and germination is also faster. It should be noted that when sowing seeds around June, soak them in cold water for a certain amount of time, about 12 to 24 hours, and wash the seeds before sowing, and at this time put them in a cool place to dry for a while, so that the seeds that show new sprouts can be sown.

It is necessary to pay attention to the wetness of the soil when breeding, many times it is necessary to change the water every few days, and at this time the sowing can not be set up in tents, but it is necessary to water frequently, so that the harm of weeds can be reduced, and a certain herbicide can also be cultivated when sowing, so that weeds will not be too frequent.

Tools and materials: 1 piece of celery root, a dish with water.

Steps: 1. Cut off the celery head, put it in a pot with warm water, the celery head is facing down at the root, the leaves are facing up, and then put it on the windowsill;

2. After the first week of celery, the leaves on the side begin to turn dry yellow, and the original yellow and tender leaves in the middle turn dark green;

3. Transfer the celery head to a pot and cover it with potting soil or mixed soil, leaving only the top of the small bud a little outside;

4. Water diligently, after a week, you can see the clean stems from the soil constantly teasing the tall reeds.

Celery, belonging to the Apiaceae plantation belt. 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 strong, also known as parsley.

The method of planting celery: the seeds need to be germinated before sowing, the seedling management should be strengthened, and the micro-fertilizer and plant growth regulators should be used reasonably.

1. Seeds need to be germinated before sowing

The epidermis of celery seeds has poor water permeability, and if it is sown directly, the germination rate is slow and the emergence rate is low. In addition, the temperature in early autumn is high, and it is not easy to emerge, so celery should be soaked and germinated before sowing. Soaking seeds is relatively simple, that is, soaking the seeds in clean water for 24 hours, washing off the mucilage of the seeds, and then germinating.

Germination has low-temperature germination and hormone germination, generally soaked with gibberellin for 12 hours, and then fished out and sown, the seedling emergence time is short, and the germination rate can be improved. This method is relatively simple, trouble-free, and effective. When germination is carried out at low temperature, it is necessary to carry out germination under the condition of 15 20 after soaking.

2. Strengthen seedling management

Celery is generally raised first and then transplanted, which can be raised in the open field in the shade or in the hole tray. At the seedling stage, the water absorption capacity is weak, and the soil should be kept moist before the emergence of seedlings, which is conducive to rapid emergence of seedlings. After the celery seedlings emerge, the root system is shallow, and the soil should be kept dry and wet.

Urea solution is sprayed every other week to promote seedling growth. Celery seedlings should be planted twice at the seedling stage, and when they have 3 or 4 leaves, they will be planted in the field, leaving strong seedlings and seedlings free of diseases and pests.

3. Rational use of micro-fertilizers and plant growth regulators

When celery is grown, many farmers will spray micronutrient fertilizers and plant growth regulators to improve yield and quality. Trace element fertilizer is mainly boron-based, and borax solution can be sprayed in the middle of growth. When using plant growth regulators, it is also necessary to pay attention to the time of use and the concentration used.

There are four steps in the method of planting celery: seed selection and germination, sowing and seedling raising, reasonable planting, and water and fertilizer management.

Seed selection and germination: it is necessary to screen out varieties with high yield, disease resistance and strong insect resistance for germination; Sowing seedlings: Wait for 30% of the celery seeds to germinate before sowing, and cover with shade nets and film after sowing; Reasonable colonization:

Apply sufficient basal fertilizer in the field, and then transplant the seedlings into the soil; Water and fertilizer management: foliar sprays of gibberellin are applied twice before celery harvest. Celery is best sown in February and June each year, and can be planted after a spine month, and silver planting is carried out during warm weather periods.

Before sowing celery, a comprehensive survey of the terrain was carried out, and the bottom water was irrigated.

Celery planting methods: sowing seedlings, planting and planting, field management, cold protection and warmth.

1. Sow seeds and raise seedlings

The best place to grow celery must be colder, and the soil suitable for celery growing must be fertile, loose, and have a good drainage system. When digging the ground, it is necessary to lay a good base fertilizer, and the land is as flat as possible. Seedlings should be packed in bags, then bundled and soaked in water for two days, then taken out of the water, after three or four days they should have germinated, and then taken to the field for sowing.

2. Planting and colonization

Once the seedlings are grown, it's time to start plucking and planting. The seedlings are planted one by one at certain intervals, and the first fertilization is carried out, using farmhouse fertilizer as much as possible.

3. Field management

After planting, don't think it's over, before the celery has not grown new roots, it needs to be watered once a day in the morning and evening, and the dead vegetable seedlings should be replenished in time. Wait until all the celery has grown new roots and new leaves. Weeds in the field should be weeded in time to prevent the absorption of nutrients in the soil.

4. Cold-proof and warm-warm

The heat and cold resistance of celery are not as good as this celery, 0 or less will be frozen, generally in mid to late November, cover the greenhouse film for insulation, pay attention to ventilation during the day, the temperature in the shed does not exceed 25 during the day, and not less than 5 at night.

Celery planting time

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, it is best to plant, and it 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 also 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 both better, and celery itself likes to grow in colder places, so this season is very suitable for growing celery.

1. Select the seedBefore planting celery, it is necessary to select high-quality seeds with high yield, strong pie resistance, and full of grains.

2. Germination treatmentSoak celery seeds in bags in clean water for one to two days to promote the seeds to absorb water and expand, which is conducive to shortening the germination time of seeds and facilitating later management.

3. Sowing methodWhen 30% of the celery seeds are white, they are evenly sown on the soft and fertile soil to make cherries, covered with a thin layer of soil, watered to keep the soil moist, and finally covered with a layer of mulch film on the soil to keep warm and moisturize.

1. Sow seeds and raise seedlingsMost areas are transplanted with seedlings, and a few areas are dominated by direct seeding. Summer sowing seedlings should pay attention to shading and cooling and preventing rain and waterlogging. During spring sowing, use a cold bed or a hot bed to keep the seedlings warm. Higher plots should be selected to raise seedlings with high furrows, so that they can be drained and irrigated.

Parsley is sown with fruit, because the skin is thick and firm, and there are oil glands, it is difficult to permeate water, and the germination is slow and untidy, so it must be soaked and germinated. After soaking the seeds for about 12 to 14 hours, rinse them with water, gently rub them with your hands while washing, rub the epidermis, spread them out and dry the seeds. Parsley seeds are light-friendly, do not cover the soil after sowing, and cover a thin layer of straw, which on the one hand prevents water evaporation, and on the other hand, prevents the seeds from being alluvial into piles when drenched.

About 10 days after sowing, the seeds germinate, i.e. the mulchweed is removed. When the seedlings grow to 2 or 3 true leaves, they can be divided, and when the seedlings grow to 4 or 5 true leaves, they can be planted. 13 15 g per 667 m2.

2) Field management. When planting, 1 m wide furrow is planted in two rows, with a plant spacing of 20 to 25 cm. Because the growth period of parsley is as long as 6 7 months, so the base fertilizer is very important, 5000 kg of organic fertilizer is applied every 667 m 2, in addition to organic fertilizer, 30 kg of ammonium sulfate, 30 kg of superphosphate, 10 kg of potassium chloride should be applied per 667 m 2, these three kinds of fertilizer except for half of the ammonium sulfate as top dressing, all the other are used as base fertilizer.

During the whole growth and development period of parsley, it is necessary to chase fertilizer at least 3 or 4 times.

Weeds will hinder the growth of parsley, so it is necessary to pay attention to frequent weeding, but parsley is a shallow-rooted vegetable, and it should not be too deep when cultivating, otherwise it will hurt the root system of parsley. It is also possible to spray 25% herbicide ether after parsley planting, and the dosage per 667 m2 shall not exceed kilograms.

Maintain soil moisture appropriately to avoid dryness and stagnant water. Excessive soil dryness often inhibits the development of parsley, slows down the growth rate, causes hollow stems and sprouts, affects quality, and reduces yield. If the soil is waterlogged, the stems are prone to rot.

3) Harvesting. When the parsley plant has grown to about 15 true leaves, you can start to harvest the fresh leaves that have grown in the middle of the plant in stages and batches until the next year. Parsley cannot be overwintered in the open field, and if you want to harvest seeds, you need to move the old roots into the greenhouse before freezing, and then plant them in the open field in April of the following year.

4) Pest control. During the growth period of parsley, there are fewer occurrences of pests and diseases. Pests include aphids, carrot flies, etc., and the main diseases are leaf spot.

Cultivation season.

Celery is cultivated in the open field in North China, and the climate suitable for celery growth in autumn is the longest, so the yield, quality, and cultivation area are also the largest. Celery can also be cultivated in a variety of protected areas to achieve anniversaries**. Generally, seedlings are cultivated in the greenhouse in spring from January to February, planted from late March to mid-April, harvested from late May to July, cultivated in autumn, sown and raised from mid-June to early July, planted in spring from early and mid-August to mid-September, and harvested in October and December.

In general, the cultivation in the protected area is mostly sown and raised in early July, mid-July to early August, planted in improved sunny furrows or solar greenhouses in September and November, and harvested in January and March.

Seeding & Management.

It is difficult for celery seedlings to emerge, so it is necessary to choose sandy loam soil with high terrain, convenient drainage and irrigation, loose soil and fertile soil for seedling raising. It is necessary to apply enough decomposed base fertilizer, and to make the soil loose, it is necessary to apply more circle fertilizer. In order to achieve fast, complete and uniform seedling, 7 to 8 days before sowing, seed soaking and germination can be carried out.

Sow seeds in mid and late June, soak them in cold water 12 14 for 12 24 hours, wash the seeds, dry them in a cool place for a while, wait for the surface of the seeds to dry, wrap them in a wet towel, put them in a cool place (15 20) to see the light to promote germination, and wash them with cold water once a day. When the seeds are budding, they can be sown, and the wet sowing method is mostly used, that is, the bottom water is watered first, and the water is mixed with sand and sown after water infiltration. Build a shade shelter on the seedlings to cool down, protect from the sun, and prevent heavy rain.

After sowing, the soil should be thin and even, the seedlings should be kept moist, generally 1 2 days in the morning and evening, water a little water until the seedlings emerge, spring and autumn sowing can not be built shade shed, to water a small water frequently, in order to facilitate the emergence of seedlings. In order to reduce the damage of weeds, 25% wettable herbicide ether can be used before emergence after sowing, 80 100kg of water can be added, and evenly sprayed on the furrow surface. Seedlings have 2 leaves at a time, and the seedling spacing is 1cm.

Seedlings 3 4 pieces of seedlings once a seedling, seedling spacing 8 10cm square, seedlings live, to carry out cultivation, to promote the seedling roots and leaf differentiation, can be applied urea 10kg mu, and remove all mulch, in order to facilitate seedling exercise. When the seedlings grow to 5 7 pieces, and the seedlings are 15 18 cm high, they can be planted. Pay attention to the prevention and control of aphids, spot blight, etc.
