What exactly causes hollow celery?

Celery is a very common vegetable in daily life and has high nutritional value. Hollow celery is a common condition; once celery becomes hollow, its fiber content increases, greatly reducing its texture. For vegetable growers, hollow celery leads to poorer quality, lower yields, and reduced income. So what is the deal with hollow celery? How can celery be prevented from becoming hollow? Friends who are interested, let's take a look!

I. Causes of hollow celery:

1. When growing celery, it has certain requirements for temperature and light. Too low a temperature and insufficient light will cause frost damage to celery and weaken leaf photosynthesis. Weakened photosynthesis will affect the roots' absorption of nutrients and water, thereby causing the hollow condition.

2. The main cause of hollow celery is high temperature and drought. Celery has certain water requirements; if water supply is uneven, it will cause celery to lack water during growth, affect the roots' absorption and transport of other nutrient elements, and cause hollow celery.

3. Celery's roots have a weak ability to absorb fertilizer, and it also has high requirements for fertilizer use. In the early stage, phosphate fertilizer needs to be applied; insufficient phosphate fertilizer will lead to symptoms such as weak seedlings and leaf differentiation. After the plant grows and matures, it will lead to hollow celery.

4. The suitable soil pH range for celery is between 6.0-7.6. Celery grows better in soil with strong fertility and in clay loam; sandy soil and sandy loam will cause hollowing of celery leaf stalks. Hollow celery is also related to harvesting: if harvesting is too late, it will affect the roots' ability to absorb nutrients, causing symptoms such as aging leaf stalks and poor nutrition.

II. Methods to prevent hollow celery:

1. When buying celery seeds, purchase them from a trustworthy seed supplier.

2. Control the temperature well. For celery cultivated in a greenhouse, the optimal daytime temperature is 15-23°C, and around 10°C at night. Do not set the temperature too low, to avoid causing celery to bolt.

3. Strengthen water and fertilizer management. Chicken manure can be used as fertilizer, and soil rich in organic matter and with strong fertility should be chosen for planting. Clay soil and sandy soil should not be chosen for planting..

4. Deal with pests and diseases in celery in a timely manner to ensure that celery has strong photosynthesis.
