Detailed Explanation of the Key Points of Soilless Cultivation Techniques for Celery

With the rise of soilless cultivation technology today, soilless cultivation has low planting costs and high yields and profits, and many vegetable growers use this technology to achieve high and excellent yields. Celery is a common vegetable for us, and its planting area is increasing year by year. So how should soilless cultivation of celery be carried out? Let's take a look together with Qinnongwang below.

1. Seed selection and seedling raising

Celery mainly includes two types: solid-stalk celery and hollow-stalk celery. Solid-stalk celery has solid leaf stalks, strong adaptability, high yield, and is also resistant to storage, but it grows relatively slowly; hollow-stalk celery has hollow leaf stalks and grows relatively quickly. In addition, there is also a celery variety — celeriac, and all are very good varieties. Before sowing, soak the seeds in clean water for 12 hours, remove them and rinse them, then wrap them in a wet gauze and place them in a greenhouse environment for germination. Rinse them with water every day, and when half of the white appears, they can be sown.

2. Cultivation method

At present, the main soilless cultivation method for celery is rock wool cultivation, which has low cost, good results, and is suitable for conditions in our country. Level the ground, compact the soil, and then make a trough 20 cm deep, 100 cm wide, and 10 cm long, then lay a layer of polyethylene film in the trough, and then fill it with substrates such as rock wool, vermiculite, or river sand. In this way, the cultivation trough for soilless cultivation is completed.

3. Planting

Strengthen fertilizer and water management before and after emergence, but when the seedlings grow two or three true leaves, they can be planted, and strong-growing seedlings should be selected for cultivation. Plant the seedlings at a spacing of 10*10 cm. If it is celeriac, it should be expanded to 20*30 cm. Generally, one seedling is planted per hole, and nutrient solution should be supplied in time after planting.

4. Cultivation management

To achieve high and excellent yields in soilless cultivation, nutrition is the key point. It can be prepared with compound fertilizer, and note that the pH value should be between 6-6.5. The suitable growth temperature for celery is 18-25 degrees, so the temperature should also be controlled within this range each time the nutrient solution is irrigated. If the root temperature is below 15 degrees for a long time, it is not conducive to root growth, and this is not conducive to increasing celery yield. In addition, celery has different nutritional needs at each growth stage. Generally, during vigorous growth, nutrient solution needs to be irrigated two or three times a day, while in the early and late stages it can be reduced accordingly. It is better to recycle nutrients regularly to avoid water deterioration, harm to the plants, and an increased probability of disease occurrence.

The above is the soilless cultivation technology for celery brought by Qinnongwang. Generally, soilless cultivated celery can be harvested about two months after planting, which is much faster than traditional planting methods. The soilless cultivation technology for celery is introduced here, and I hope it can be helpful to you.
