What is the latest cause of hollow celery?
Celery is a very common vegetable in daily life and has high nutritional value. Hollow celery is a common symptom; once celery becomes hollow, its fiber content increases, greatly reducing its taste. For vegetable farmers, hollow celery leads to poorer quality and reduced yield, affecting profits. So what causes hollow celery? How can celery be prevented from becoming hollow? Friends who are interested, let's take a look!
1. Causes of hollow celery:
1. When planting celery, there are certain requirements for temperature and light. Too low a temperature and insufficient light will cause frost damage to celery and weaken the photosynthesis of the leaves. Weakened photosynthesis will affect the roots' absorption of nutrients and water, thereby causing the hollow phenomenon.
2. The main cause of hollow celery is high temperature and drought. Celery has certain requirements for water. If the 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 roots have a weak ability to absorb fertilizer, and there are also 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 high fertility and in clay loam. Sandy soil and sandy loam will cause hollowing of celery petioles. Hollow celery is also related to harvesting. If harvesting is too late, it will affect the root system's ability to absorb nutrients, causing symptoms such as aging petioles and poor nutrition.
2. Methods to prevent hollow celery:
1. When buying celery seeds, choose a trustworthy seed supplier to purchase from.
2. Control the temperature well. The optimal daytime temperature for cultivating celery in a greenhouse is 15-23°C, and around 10°C at night. Do not set the temperature too low, to avoid causing celery bolting.
3. Strengthen water and fertilizer management. Chicken manure can be used as fertilizer, and soil rich in organic matter and high in fertility should be chosen for planting. Clay 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.
