Celery is rich in crude fiber and has good curative effect in improving gastrointestinal function. In recent years, as people understand the health of celery, the planting area of ??celery is increasing. So, where is celery? The best time to plant is, but what should you pay attention to during the management process? 1. Celery planting time.

Celery is divided into four types according to different planting times:

The first is spring celery. The sowing time of spring celery is January in the north. The seedling cultivation time is from January to March, and the planting time is from March to April. It can be harvested around June. In the Yangtze River Basin, March is the suitable sowing period every year. If sown too early, low-temperature weather will have a certain impact on celery. If there are too many low-temperature days, celery will differentiate prematurely and mature in advance, affecting yield and quality.

The second is summer celery. Summer celery is grown in the open field from April to May every year, planted in June-July, and can be harvested in late August. Celery is generally planted in spring and autumn. If it is grown in the open in summer, celery will grow poorly and produce lower yields. Instead, it will encounter rainy and hot weather, more severe pests and diseases, and more dead seedlings. Therefore, compared with spring and autumn, The planting area of ??summer celery is not large.

The third is autumn celery. Autumn celery is sown in the north from June to July, planted from August to September, and harvested from October to December. The South can postpone it appropriately.

The fourth is winter celery. When planting celery in winter, it should be planted in areas with higher temperatures. In the south of the Yangtze River Basin, it can be sown in the open air, while in the north it should be planted in greenhouses. In southern open-air planting, sowing is carried out from September to November, and harvest can be achieved in April of the following year. 2. Things to note when growing celery.

First, pay attention to seed selection.

Celery is divided into two types: native celery and Chinese celery. In the process of selecting and planting, the selection should be based on the local market demand and the basis of one's own planting technology. In addition, celery seeds have a dormant period of more than a month after harvesting, so the seeds cannot be planted immediately after harvesting. The seeds of the previous year must be used for sowing.

The second is to pay attention to germination. The germination temperature of celery seeds is 4 degrees Celsius to 30 degrees Celsius. Germination is better when the temperature is around 20 degrees Celsius. However, if conditions permit, it can be treated with variable temperatures. Keep it at 25 degrees Celsius for 8 hours, and then keep it at 15 degrees Celsius for 18 hours. The germination rate is the highest.

The third is to pay attention to water and fertilizer management.

Although the root system of celery is light, its distribution is shallow. In addition, celery is also a crop that requires a lot of water. The irrigation of celery should be kept small and frequent. Each watering should be done in the morning and evening when the temperature is low. Do this to avoid excessive temperature at noon, which may cause damage to the celery roots. When watering, attention should be paid to the application of fertilizers. Topdressing 2-3 times during the seedling stage, mainly nitrogen fertilizer.

The fourth is to pay attention to pests and diseases. Common diseases of celery are soft rot, sclerotinia, black rot, etc. During the planting process, we must pay attention to prevention. Pay attention to rotating celery on a piece of land. The rotation interval should be more than 2 years. During the seedling raising process, we must pay attention to seedbed disinfection and cultivate non-toxic strong seedlings.

There are many things that need to be paid attention to when planting celery. Different celery varieties, different planting times, different planting areas, as well as open-air planting and greenhouse planting, all have different emphases. You can follow the Choose appropriate management methods under different circumstances to improve celery yield and quality.
