Soilless cultivation techniques of celery

With the rise of soilless cultivation technology, soilless cultivation has the advantages of low planting cost, high yield and high profit. Many vegetable farmers use this technology to achieve high yield and high yield. Celery is our common vegetable, and our planting area is increasing year by year, so how to carry out soilless cultivation of celery? let's take a look at the pro-agricultural network.

1. Seed selection and nursery

Celery is mainly divided into two types: solid straw celery and empty straw celery, solid straw celery petiole is full, adaptability is strong, yield is high, but it is resistant to storage, but grows slowly, while hollow stalk celery petiole grows faster, in addition, there is a variety of celery-celery, are very good varieties. Soak the seeds in clean water for 12 hours before sowing, remove and rinse, then put them in a greenhouse environment wrapped with wet gauze to accelerate germination, rinse with water every day, and sow seeds when half of them are left blank.

2. Cultivation methods.

At present, the soilless cultivation of celery is mainly rock wool cultivation, which has the advantages of low cost, good effect, and suitable for the conditions of our country. The ground is leveled, the soil is solid, and then the trough of deep 20cm, wide 100cm and long 10cm is made, and then a layer of polyethylene film is spread in the trough, and then filled with substrates such as rock wool, vermiculite or river sand, so that the cultivation trough of soilless cultivation is completed.

3. Colonization

The management of fertilizer and water should be strengthened before and after emergence, but the seedlings can be planted when they grow two or three true leaves, and the seedlings with strong growth can be selected for cultivation. 10*10cm cultivation of seedlings according to row spacing, if it is celery, it should be expanded to 20*30cm, usually one seedling per hole, and timely supply of nutrient solution after planting.

4. Cultivation and management

In order to achieve high yield and high yield of soilless cultivation, nutrition is the key point, compound fertilizer can be used, and the pH value should be between 6 and 6.5. The suitable temperature for celery growth is 18-25 degrees, so the temperature should be controlled at this temperature every time the nutrient solution is irrigated. If the root temperature is lower than 15 degrees for a long time, it is not conducive to root growth, which is not conducive to increase the yield of celery. In addition, the demand for nutrition of celery is also different in each growth stage. generally, the nutrient solution needs to be irrigated two or three times a day in exuberant growth, but it can be reduced correspondingly in the early and later stages, and the nutrition should be recycled better regularly to avoid deterioration of the water body and harm to plants. so as not to increase the risk of disease.

The above are the soilless cultivation techniques of celery brought by the pro-agricultural network. Generally, soilless cultivation of celery can be harvested in about two months after planting, which is much faster than the traditional planting methods. The soilless cultivation techniques of celery are introduced here, hoping to help you.
