How to choose celery? What are the methods of raising seedlings?

Celery is a very common household vegetable, which is rich in practice, green and nutritious, and has a good effect on improving gastrointestinal function. At present, many families or gardens have the habit of growing celery, because its daily management is relatively simple, so that it can not only feed itself, but also be sold on the market and earn a profit. So in the process of planting celery, how to select seeds and raise seedlings? Let's get to know it.

Key points of selection of celery

Celery can be divided into two kinds: native celery and parsley, which should be selected according to the needs of the local market and the basis of their own planting technology. In addition, celery varieties should be selected according to different planting time. For example, the planting time of spring celery is in the north in January, and the seedling time is from January to March; summer celery is raised in the open field from April to May every year; autumn celery is sown in the north from June to July, which can be appropriately delayed in the south; winter celery should be planted in places with higher temperatures, open-air sowing in the south of the Yangtze River basin (September to November), and in the north in the greenhouse.

Seedling raising skills of celery

1. Temperature control and budding

The lowest temperature for celery seed germination is 4 ℃, and the optimum temperature is 15-20 ℃. At the optimum temperature, it takes 4-7 days to germinate, and the seedling stage is about 40 days. It is necessary to control temperature and accelerate germination before raising seedlings, and the temperature is controlled within the optimum temperature range, and it can germinate after about 10 days.

2. Seedbed preparation

The nursery bed should choose the land with loose soil, fertile soil and rich organic matter, and at the same time ensure that the land has the characteristics of good water retention, convenient drainage and irrigation, good ventilation and so on.

3. Sowing and raising seedlings

7-10 days before sowing, 48% Zhongdingling EC can be used to control weeds, and the herbicides can be evenly sprayed according to 80,120g per mu and 60kg of water. Then level the nursery bed and prepare for sowing. When about 70% of the seeds germinate, you can sow the seeds, pay attention to watering the bottom water, then mix the germinated seeds with fine screened sand, sow them by hand, and then evenly screen and cover the fine sand with a thickness of 2-3 mm. The whole seedling can be produced 3-5 days after sowing.

4. Seedling stage management

Keep the seedling bed moist during seedling rearing. If the surface becomes dry, you can use a sprayer to keep the surface moist. In case of high temperature, choose to use a sunshade net with a shading rate of 50% to shade and cool down. In addition, during the seedling raising period, potassium dihydrogen phosphate can be sprayed after 2 leaves and 1 heart according to the growth trend, and the seedlings can be separated at the same time. In the process of interplanting, we should also pay attention to the fact that the distance between celery plants is about 4 centimeters, which can ensure that celery has good ventilation and light transmittance. When the height of celery grows to 20 centimeters and five true leaves appear, we can do the follow-up planting work.

The above is a full introduction to the selection and breeding of celery. Generally speaking, the daily management of celery is not too complicated, but in fact, there are many small skills in its seedling raising work. Once it is not mastered well, it is easy to have a low emergence rate and serious diseases, thus affecting the yield. Therefore, the work during the breeding period must be put in place.
