What are the benefits of dense planting of celery? How to grow celery seedlings first and then transplant them

Appropriate density of celery planting is conducive to improving the commercial value of celery. High-quality celery will be more competitive in the market and have a better price advantage. However, the planting density of celery needs to be appropriate according to the celery variety. High-density planting will lead to the breeding of celery pests and diseases, which are difficult to control and then spread. In particular, the greater the planting density, the more difficult it is to prevent and control celery damping-off and soft rot. Celery is a vegetable that grows very fast. Proper adjustment of the planting density will lead to better growth.

Preparation for celery planting

1. Dry the seeds for one day about a week before sowing, then soak them in cool water for 24 hours, changing the water every 8 hours. Then rub the seeds and rinse them with clean water to remove impurities until the water is clear.

2. Wrap the treated seeds with a towel, squeeze out some of the water, and put them in the refrigerator at a temperature of about 5°C. Rinse the seeds with clean water once in the morning and evening every day. After two days, spread the seeds out in a lighted place. Rinse with cold water twice a day. After each rinse, blow the seeds with a fan for 5 to 10 minutes to dry the water on the seeds. Generally, they will germinate after 5 to 6 days.

What are the benefits of intensive planting of celery?

First, intensive planting can save land and fertilizer and water.

After celery is sown and sprouted, its stems and leaves grow upright, the stems gather into a bundle, and the leaves and petioles are small. On the same area of ​​land, the yield may differ by one or two if the plants are planted closely or sparsely. Close planting can not only save land use, but also save fertilizer and water, and more importantly, it can increase yield.

Secondly, the physiological characteristics of celery determine that celery should be planted densely.

Celery likes water and fertilizer, but is not heat-resistant. Its root system is not well developed and is shallow in the soil. However, to support the vigorous growth of stems and leaves, it must have sufficient water and fertilizer to maintain the nutrients needed for stem and leaf growth. Dense planting can solve the problem of soil moisture evaporation and play a role in moisturizing.

Finally, close planting helps celery stems to elongate and prevent aging.

The reproductive growth of celery requires a large amount of fertilizer and water to make the branches and leaves luxuriant and the stems strong and thick. If the planting density is too sparse, the stems and petioles will easily fall apart and quickly become aged under photosynthesis, which seriously affects the yield and quality of celery. With appropriate dense planting, the stems and petioles will not fall apart easily, and will grow upright faster and become taller. At the same time, the celery stems will not become more fibrous, hollow and aged.

In summary, intensive planting of celery can not only save land and fertilizer and water, but also improve yield and quality.

The method of raising celery seedlings first and then transplanting

1. The planting density is the highest when the seeds are sown directly and then harvested. The entire growth cycle of celery is relatively short and fast during planting, so the requirements for water and fertilizer are more "urgent", but the single amount is not that large. Therefore, it is a method of fertilizing in small amounts and multiple times, as well as irrigation.

2. Of course, the direct sowing method is also planted in the "vegetable bed", so this requires a certain amount of effort and time in the previous land preparation.

3. There is also a second planting method, which is to raise seedlings first and then transplant them. In the early stage of raising seedlings, the density of the seedlings is still relatively large, so the density of subsequent transplanting should be smaller. In my hometown in rural Gansu, the spacing between celery plants is about 10 cm to 15 cm. The row spacing is also within this range.

4. Raising seedlings first and then transplanting also requires "vegetable bed" planting, but it requires one more step than the previous direct sowing method, that is, transplanting with a hoe. Generally, the transplanting process is like this: first dig out the cultivated celery seedlings with intact roots, and then transplant them. Generally, they are dug and transplanted on the same day. When transplanting, dig ditches first, and then transplant one by one. After transplanting a bed, it needs to be irrigated. Note that the irrigation should be "gentle" at this time.
