New planting techniques of celery in summer

Celery is a kind of side vegetable that many people like very much. It is distributed in all parts of our country, and its market demand is very large. And the adaptability of celery is relatively strong and can be planted all year round. However, when planting in summer, because of the high temperature, some places are different from other seasons. So the editor today brings you the planting technology of summer celery. Let's take a look at it.

1. Seed treatment

Celery seeds are difficult to germinate if they are sown without treatment. Because the dormancy period of celery seeds is relatively long, the dormancy period of celery seeds should be broken before sowing. First, dry the seeds for about 3 hours, then soak the seeds in water for about 11 hours, and then wash the mucus off the seeds.

2. Transplanting seedlings

After the seed treatment, we should pay attention to control the temperature when sowing, the temperature should be kept at about 18 degrees, and it can germinate in about 1-3 weeks. If the temperature exceeds 25 degrees, it will be very difficult or even impossible for seeds to germinate. When the seedlings grow about 5 true leaves, they can begin to transplant. When planting, it should be planted separately according to the size of the seedlings. When digging up the seedlings, we should be careful not to hurt the seedlings within the country, mainly transplanting with soil. Then we should pay attention to it after 5: 00 p. M. to prevent the temperature from getting too high and pour enough root water after planting.

3. Build a shed to shade the sun

After the seedlings are planted, it is necessary to do a good job in setting up a shed, which is about 2.2 meters high. Then cover the shed with a sunshade net to make sure that the celery is not shone in the sun from ten to three o'clock in the afternoon. When planting in summer, celery should do a good job of shading the sun throughout the growing season. The shading net can be black, which can reduce the surface temperature and improve the field climate, which is very beneficial to the production and photosynthesis of celery. And the greenhouse can also defend against rainstorm and strong wind, reduce the mechanical damage of celery and improve the planting efficiency.

4. Fertilizer and water management

After the celery seedlings are planted and survive, until the plant is closed, shallow ploughing should be done for about 3 times, and each shallow ploughing should be carried out once with topdressing. Fertilizers are mainly compound fertilizer and dry dung, which are usually watered once every time. If it rains, there is no need to water them. In the first two times of topdressing, the amount of topdressing should be kept at about 1 pound 5 of the total fertilizer. The last two times were kept at about 70%, and the quick-acting fertilizer could be applied again before the plant was closed. The amount of topdressing per mu should be controlled at about 2500kg. Finally, foliar fertilizer should be properly sprayed in the middle and later stage to promote the elongation of celery petiole.

The above is a brief introduction to the new technology of growing celery in summer. In summer, because the temperature is very high, it will have a great impact on the growth of celery, so we must pay more attention to planting. That's all for today's introduction.
