New technology of soilless culture of celery

1. Selection and breeding

Celery mainly has two types: solid straw celery and empty straw celery. The solid straw celery has full petioles, strong adaptability, high yield, and storage resistance, but grows slowly; while empty straw celery has hollow petioles and grows faster, and there are also A variety of celery-celery, are very good varieties. Before sowing, soak the seeds in clean water for 12 hours, remove and rinse, and then wrap them with wet gauze towels and place them in a greenhouse environment to accelerate germination. Rinse them with water every day, and sow when half of the white space appears.

2. Cultivation methods

Nowadays, the soilless cultivation method of celery is mainly rock wool cultivation, its cost is low, and it is suitable for our country. Level the ground, compact the soil, and make a tank with a depth of 20 cm, a width of 100 cm, and a length of 10 cm. Then, put a layer of polyethylene film in the tank, and then fill it with a matrix such as rock wool, vermiculite or river sand. The cultivation tank for soilless cultivation is completed.

3. Colonization

Strengthen fertilizer and water management before and after emergence, but the seedlings can be planted when two or three true leaves are grown. Choose strong-growing seedlings for cultivation. Cultivate the seedlings according to the row spacing of 10*10cm. If it is celery, expand it to 20*30cm. Generally, plant one seedling per hole, and supply nutrient solution in time after planting.

4. Cultivation management

In order to achieve high yield and excellent yield of soilless cultivation, nutrition is the key point, and compound fertilizer can be used to adjust the pH value 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 you water the nutrient solution. If the temperature of the root system 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 has different nutritional requirements in each growth stage. Generally, it needs to be watered two or three times a day when it is growing. It can be reduced in the early and late stages. The nutrients should be recycled regularly to avoid water deterioration and harm to the plants. The incidence of disease increases. The above is the soilless cultivation technology of celery brought by the greenhouse vegetable net. Generally, the soilless cultivation of celery can be harvested in about two months after planting, which is much faster than the traditional planting method. The soilless cultivation technology of celery is introduced here. It will help you.
