New technology of celery soilless cultivation

1.Selection and breeding

There are two types of celery: solid straw celery and empty straw celery. The solid straw celery has a large petiole, strong adaptability, high yield, and is resistant to storage, but grows slowly; while the empty straw celery has a hollow petiole and grows faster. Variety of celery-celery, are very good varieties. Immerse the seeds in clear water for 12 hours before sowing, remove and rinse them, then wrap them in a wet gauze and place them in a greenhouse environment to germinate. Rinse them with water every day. When half of the white space appears, you can sow the seeds.

2. Cultivation method

At present, the soilless cultivation method of celery is mainly rock wool cultivation, which has low cost, good effect, and is suitable for China's conditions. Level the ground and compact the soil, then make a 20cm deep, 100cm wide, and 10cm long tank, and then lay a layer of polyethylene film in the tank and fill it with rock wool, vermiculite, or river sand. The soilless cultivation tank is completed.

3. Colonization

When the fertilization and water management is strengthened before and after emergence, but when the seedlings grow two or three true leaves, they can be planted. Select strong seedlings for cultivation. The seedlings are cultivated according to the row spacing of 10 * 10cm. If it is celery, it must be expanded to 20 * 30cm. Generally, one seedling is planted per hole, and the nutrient solution is supplied in time after planting.

4. Cultivation management

In order to achieve high yield and excellent yield in soilless cultivation, nutrition is the key point. Compound fertilizer can be used to mix it. Note that the pH value should be between 6 and 6.5. The appropriate temperature for celery growth is 18-25 degrees, so the temperature should be controlled at this temperature every time when the nutrient solution is watered. 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 the increase of celery yield. In addition, celery's nutritional needs are different at each growth stage. Generally, veggies need to be watered two or three times a day during vigorous growth, and they can be reduced accordingly in the early and late stages. It is better to regularly recover nutrients to prevent water deterioration and harm plants. Increased incidence of disease. The above is the soilless cultivation technology of celery brought by the greenhouse vegetable network. Generally, soilless cultivation of celery can be harvested in about two months after planting, which is much faster than the traditional cultivation method. The soilless cultivation technology of celery is introduced here. I hope to Helpful to you.
