Boron deficiency in the soil is a major cause of petiole cracking. To prevent this, apply 0.5 to 1 kg of borax per acre as a base fertilizer. If early signs of cracking are observed, a foliar spray of 0.2% to 0.5% borax solution can be applied, or a root drench with 0.25% borax solution may also help. This ensures the plants receive adequate boron during critical growth stages.
Improper sowing dates or insufficient nitrogen fertilizer can lead to delayed growth and weak plant structures. If planting is too late or nitrogen levels are low, the plants become more susceptible to cold stress, which can cause petiole softening and hollowing. To avoid this, farmers should choose sowing dates based on local climate and growing conditions. It's also important to manage fertilization and irrigation properly during the early and mid-growth stages, ensuring enough nitrogen is available for healthy development.
Cold-sensitive celery varieties are at risk when temperatures drop below 0°C. Freezing can damage the cell structure of the petioles, making it impossible for the tissue to recover even after temperatures rise. This leads to increased cell gaps and internal hollowing. To protect the crop, proper insulation and winter protection measures should be implemented during cultivation to ensure the plants survive the cold season safely.
Additionally, some celery varieties, such as degraded celery and common celery, are prone to natural cross-pollination, which can result in genetic degradation over time. To maintain variety purity, it's essential to isolate seed-producing plants from other celery types. Farmers should also avoid using hollow or weakened plants for seed production to ensure high-quality seeds that retain the desired traits.
By following these practices, growers can significantly reduce the occurrence of petiole cracking, hollowing, and other issues, leading to healthier crops and better yields.
Veterinary Ultrasound Scanner
As customers have higher and higher requirements for animal reproduction and animal disease diagnosis and treatment, traditional diagnostic methods such as visual inspection, stethoscope listening, thermometer inspection, and percussion and hammering can no longer meet the needs of animal husbandry production and veterinary clinics. Today, B-ultrasound is playing a big role in human medical diagnosis, and in the future, B-ultrasound will also play a role in animal medicine. We should promote the use of veterinary ultrasound scanner step by step according to the actual situation, popularize the knowledge of the use of veterinary ultrasound scanner, take this as an opportunity, and use it as a ladder to improve the level of veterinary practice in our country.
