Why is the celery petiole hollow? In the process of planting vegetables, the stalk of celery has hollowness due to various reasons, which is not only unfavorable to the growth of celery plants, but also reduces the economic benefits of celery planting. Therefore, the reason why celery petiole hollow is simple is discussed today. Prevention measures, I hope to help everyone. 1. Planting high quality varieties Some celery varieties are hollowed out after years of planting degradation, or hollow because of the poor adaptability of celery; When buying celery seeds, you must go to the regular distribution point to buy quality varieties. 2, suitable temperature Celery is a cold-tolerant vegetable that needs to be planted in cold and humid environment. During greenhouse planting, the daytime temperature should be maintained at 15-23 degrees, the temperature should not exceed 25 degrees, and the nighttime temperature should be maintained at about 10 degrees. Can reduce nutrient consumption and effectively avoid hollowing out; When the night temperature is below 5 degrees, celery is prone to freezing damage and convulsions. 3. Rational fertilization The celery planting soil requires: neutral or slightly acidic soil pH, avoiding clay and sandy soil planting; Apply 5 tons of high-quality decomposed organic fertilizer per mu as the base fertilizer, and apply the quick-acting nitrogen fertilizer as the top-loading fertilizer, and increase the application of potassium fertilizer. Each time it is used for 20-25kg, apply fertilizer once every 15 days; Celery is more sensitive to the reaction of boron fertilizer. When the boron fertilizer is insufficient, cracking stem disease will occur. It can be sprayed with 0.3%-0.5% borax solution, and it can also prevent hollow disease. 4, scientific watering When celery is watered, take small water and pour water, keep the soil moisture 60-80%, and drain it in time during rainy season; Water is poured every 15 days, and the amount of water should not be too much when watering; In the vigorous growth period of celery, sufficient water should be provided, and watering should be sufficient 15 days before harvesting. 5, timely harvest The celery harvested in the greenhouse should not be too late, otherwise it will easily lead to senescence of the petiole, weakening of nutrients absorbed by the roots, and insufficient nutrient-induced rupture of the parenchyma cells of the petiole, resulting in a hollow phenomenon.
