Celery fertilizer pay attention

Celery is a cool-weather vegetable that is rich in nutrients and widely enjoyed for its crisp texture and health benefits. It's also known for its potential to help manage hypertension and lower cholesterol, earning it the nickname "the blood pressure and lipid-lowering vegetable." Growing high-quality celery requires careful field management, especially when it comes to fertilization and soil care. First, celery has a high demand for nitrogen throughout its growth cycle. The primary source of top-dressing should be ammonium nitrate, applied in small amounts—typically 2 to 3 times during the growing season. If the soil lacks boron, it's recommended to apply 0.5 to 0.75 kg of borax per acre to prevent petiole cracking, which can reduce the vegetable’s market value. Additionally, spraying a 0.2% to 0.4% calcium chloride solution can help prevent black heart disease, a common issue in celery cultivation. Second, it's important to avoid using urea as a top-dressing fertilizer. Applying urea can slow down celery growth, increase cellulose content, and cause the plants to age more quickly, leading to a decline in quality and a bitter taste when consumed. Therefore, urea should be completely avoided during the entire growth period of celery. Third, incorporating organic fertilizers can significantly improve both the quality and yield of celery. Using well-composted poultry manure, such as from chickens or ducks, is an effective way to enhance soil fertility and plant health. However, it's crucial not to use raw or undecomposed farmyard manure, as this can lead to root burn and rot. When properly applied, organic fertilizers make the celery stalks softer and thicker, reduce fiber content, and ultimately result in better flavor and higher yields. Once the celery reaches a height of over 40 centimeters, it's ready for harvest and can be sold in the market. By following these practices, farmers can ensure they grow healthy, high-quality celery that meets both nutritional and commercial standards.

Imported Premium Coupling Reagent

In plastic mixing, a plastic additive that improves the interfacial properties of a synthetic resin with an inorganic filler or reinforcer. Also known as surface modifier. It can reduce the viscosity of the synthetic resin melt and improve the dispersion of the filler to improve the processing performance in the process of plastic processing, so that the product can obtain good surface quality and mechanical, thermal and electrical properties.

Its dosage is generally 0.5 ~ 2% of the dosage of filler. Coupling agent is generally composed of two parts: one is the inorganic group, which can interact with the inorganic filler or enhance the material; The other part is the organophilic group, can interact with the synthetic resin.
