What's with the hollow celery?

Celery is a very common vegetable in life, which has high nutritional value. Celery hollow is a common symptom, after the hollow celery cellulose increased, greatly reducing the taste of celery. For vegetable farmers, celery hollow will cause deterioration of quality, yield decline, affecting income. So, what about celery hollowness? How can we prevent celery from being hollow? If you are interested, let's have a look.

First, the causes of celery hollowness:

1. When planting celery, there are certain requirements for temperature and light. Too low temperature and insufficient light will lead to the freezing injury of celery hands and the weakening of leaf photosynthesis. The weakening of photosynthesis will affect the root absorption of nutrients and water, resulting in hollow phenomenon.

2. The main cause of celery hollow is high temperature and drought. Celery has certain requirements for water. If the water supply is uniform, it will lead to lack of water in the growth of celery, affect the absorption and transport of other nutrient elements in the root, and cause celery hollow.

3. The ability of celery root to absorb fertilizer is weak, and there are high requirements for the use of fertilizer. In the initial stage, it is necessary to apply phosphate fertilizer, the lack of phosphate fertilizer will lead to seedling thinness, leaf differentiation and other symptoms. After growing and maturing, it will lead to celery hollow.

4. The PH value of soil pH of celery is between 6.07.6.celery grows better in fertile soil and clay loam, sandy soil and sandy loam can cause hollow petiole of celery, and the hollow of celery is also related to harvest. If harvested too late, it will affect the nutrient absorption capacity of roots, resulting in petiole aging, malnutrition and other symptoms.

2. Ways to prevent celery from being hollow:

1. When buying celery seeds, choose a reliable seed department to buy.

2. To grasp the temperature, the best temperature for celery cultivation in greenhouse is 15-23 ℃ in daytime and 10 ℃ at night. The temperature should not be set too low to avoid bolting of celery.

3. To strengthen the management of water and fertilizer, chicken manure can be used as fertilizer, and the soil rich in organic matter and strong fertility can be selected, but clay and sandy soil can not be selected.

4. Deal with the diseases and insects in celery in time to ensure that celery has strong photosynthesis.
