The latest course of new techniques and methods for planting celery in summer

Celery is a favorite side vegetable for many people. It is distributed all over China, and its market demand is very large. And celery adaptability is relatively strong, can be planted throughout the year. However, in summer planting, because of the high temperature, some places are different from other seasons. So Xiaobian brought you the planting technology of summer celery today. Let's take a look at it together!

1. Seed treatment

Celery seeds are difficult to germinate if sown untreated. Because celery seeds have a long dormancy period, break the dormancy period before sowing. First, the seeds are dried for about 3 hours, then the seeds are soaked in water for about 11 hours, and then the mucus on the seeds is washed off. After washing, dry the seeds to half dry, then wrap the seeds in a damp cloth, place them in an environment of about 5 degrees Celsius for about 12 hours, then take them out and place them in a cool place, repeat about 3 times.

2. Transplanting seedlings

After the seed treatment, pay attention to controlling the temperature when sowing, keep the temperature at about 18 degrees, and germinate in about 1-3 weeks. If the temperature exceeds 25 degrees, the seed germination will become very difficult or even impossible. When the seedlings grow about 5 true leaves, they can start transplanting. When planting, plant separately according to the size of seedlings. When digging out seedlings, pay attention not to hurt the seedlings inside the country, mainly with soil transplantation. Then pay attention to should be carried out after 5 p.m., to prevent the temperature is too high, after planting, pour enough root water.

3. Shading

After seedling planting, we should do a good job of building a shed with a height of about 2.2 meters. Then cover the canopy with a net so that the sun doesn't shine on the celery from 10 to 3 p.m. every day. When growing in summer, celery should be shaded throughout its growing season. Sunshade net can be mainly black, can reduce the surface temperature, improve the field climate, celery production and photosynthesis are very beneficial. Moreover, the greenhouse can also defend against rainstorm, resist strong wind and the like, reduce mechanical damage of celery and improve planting efficiency.

4. Fertilizer and water management

Celery seedlings after planting survival, until the plant closed before, to shallow tillage about 3 times, each time the best shallow tillage and topdressing work once. Fertilizer to compound fertilizer, dry manure residue based, usually every time fertilizer should be watered once, in case of rain, then do not water. The first two topdressing time, its topdressing amount to maintain in the total fertilizer amount of about 1/5 can be. The last two treatments were kept at 70%, and the quick-acting fertilizer could be applied again before the plants were sealed. The topdressing amount per mu should be controlled at about 2500kg, and foliar fertilizer should be sprayed appropriately in the middle and late stages to promote the elongation of celery petiole.

The above is a brief introduction to the new technology of summer celery cultivation. Because the temperature is very high in summer, it will have a greater impact on the growth of celery, so everyone must pay more attention when planting. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
