Planting technique of celery

Celery is a kind of vegetable of Umbelliferae, which has very high nutritional value and is rich in protein, minerals and other nutrients. After being introduced into our country, it is loved by many people, so now the planting area in our country is very large. Although the planting area is large, there are many people who do not know how to grow it. So the editor brings you the planting technology of celery today. Let's take a look at it.

1. Sowing and raising seedlings

The sowing time of celery is reasonably adjusted according to the planting method, and if it is planted in a greenhouse, it is usually carried out in February. If it is planted in plastic arch shed or sunny bed, it should be postponed to March appropriately, and if it is cultivated in open field, then sow seeds before and after Ching Ming Festival. Before raising seedlings, we should also do a good job in the soil preparation and fertilization of the seedling bed, apply sufficient mature farm manure, spread nutritious soil according to a certain proportion, and then pour enough water. Before sowing, soak the seeds in warm water of about 40 degrees for one day to promote germination, and then sprinkle them evenly on the seedbed, covering fine soil, the temperature is controlled at about 18 degrees, and it can germinate in about half a month.

2. Seedling stage management

After celery seeds germinate, attention should be paid to keeping the soil moist and improving the survival rate of seedlings. Then the interseedling work was carried out when the seedlings grew about 3 leaves, and the seedlings of celery should be planted for about 3 times during the whole seedling stage. And it is rarefied water and fertilizer for about 5 times, mainly nitrogen fertilizer in the early stage, and increase the proportion of phosphorus and potassium fertilizer in the later stage. When the seedlings grow to about 6 cm, uncover the plastic film and refine the seedlings. Finally, when the seedlings are two months old, 12 centimeters tall and 5 leaves, they can be planted at the right time.

3. Timely planting

Before planting, it is also necessary to do a good job of soil preparation and fertilization in the field. Choose strong seedlings and plant them from the outside to the inside. The planting depth can be kept without rhizome, the plant spacing should be controlled at about 25 cm, and the planting density should be controlled. After planting, we should pay attention to control the temperature, the daytime temperature is controlled at about 18 degrees, and the temperature difference between day and night is controlled at 10 degrees. When the seedlings grow to about 15 cm high, they begin to carry out water and fertilizer management, topdressing once in 2-3 weeks, and can be harvested in about two months.

4. Field management

After celery planting, we should do a good job of water and fertilizer to ensure that the soil has a suitable water content. After about 2-3 weeks, the soil can be kept dry and wet, and then the work of intermediate ploughing and weeding should be done well, after a month of planting. Celery has entered a period of vigorous growth, so it should be flooded and fertilized at this time. In planting, we should also pay attention to weeding. Because too many weeds will rob the nutrition and water needed for the growth of celery, resulting in a decline in the yield of celery, seriously affecting the efficiency of planting.

The above is a brief introduction of celery planting technology. The planting technology of celery is actually relatively simple, but we can not relax the management, strengthening management is the key to ensure production. That's all for today's introduction.
