Celery is an alias of western celery, celery, etc. Its petiole is soft, crisp, sweet and contains rich
Vitamins and mineral salts. In recent years, the cultivated area in South China has been increasing. How to achieve high yield and quality? Specific cultivation techniques are as follows: 1. Cultivation season: Celery prefers a cool and mild climate, is not tolerant to high temperatures, and the optimal temperature for growth is 15°C to 25°C. High temperature growth above 26°C is impeded, quality deteriorates, and diseases are prone to occur. At present, many rice cultivation areas are planted in the winter-free fields after the rice harvest in November. They can be sown from September to October, transplanted after the end of November, and listed on the second year of the Spring Festival. 2. Sowing and raising seedlings: The celery is mostly transplanted with seedlings and seedlings. The seedbed should be selected for shading, convenient irrigation and drainage, fertile soil and loose sandy loam. Before sowing, we will cultivate tillage soil, apply basal fertilizer, and make full preparations. Pouring water. Early sowing should be carried out with low-temperature bud treatment, after October sowing can be used without sowing Mao. After the seedlings are lifted, the coverings are peeled off. During the high temperature season, it can be put on the surface to facilitate cooling and heat preservation, and to prevent direct sunlight and direct erosion of rainwater. Pay attention to watering and keep the soil moist. The seedling period is about 50 days to 60 days, pay attention to seedlings, Qi Miao and strengthen the management of fertilizer and water. 3, transplanting seedling colonization: When the seedlings grow to 5 - 6 true leaves, seedlings up to about 10 cm can be planted. Fixed value should be selected ventilation, sunny, loose and fertile soil plots, before setting sun-drying, full base fertilizer, the general maturity of each seedlings rotten organic fertilizer 3000 kg - 4000 kg, superphosphate 40 kg - 50 kg, sulfuric acid Potassium 7 kilograms - 10 kilograms, ammonium sulfate 30 kilograms - 40 kilograms or 75 kilograms of compound fertilizer and apply a certain amount of phosphorus and potash fertilizer, apply enough base fertilizer and turn over. The fertilizer and the soil were mixed evenly, flat and planted, and the width of 1.5 to 1.7 meters wide. 4, fertilizer and water management: celery due to tall and thick plants, high yield, long growth period, the need for more fertilizer, adequate fertilizer and water supply is a guarantee of high quality and high yield. After 7 days to 10 days after colonization, 1 thin layer of faecal water or 5 kg of urea per acre can be applied for 1 time to promote good seedling root formation and restore growth. After the use of urea 10 kg per mu or 30% to 40% of the human fecal urine water applied 1 to 2 times to promote the growth of the heart. The fastest growing period from the 50th to the 70th day after planting is the key period for the production. It should be topdressed with a suitable amount of phosphorus and potassium to fully meet the needs of the celery for phosphorus and potash fertilizer. Urea can be used per mu. Kilograms, compound fertilizer 10 kilograms mixed application, after the use of urea 10 kilograms per mu, compound fertilizer 5 kilograms applied 1 to 2 times, the whole period of about top dressing 5 times to 6 times. 5. Pest Control: The main diseases of celery include blight, leaf spot, black rot, and soft rot. Physiological disorders include heartburn, hollows, and stem cracks; the main pests are aphids. 6. Harvesting: The specific harvesting standards of celery depend on the cultivation method and market demand. Generally, harvesting can be started 90 days to 120 days after planting. When harvesting, the outermost leaves are not brown, and the leaves are not harvested before being burned. should. Generally, the output per mu can reach 5,000 kg or more, and the highest one can reach 10,000 kg.
Cosmetic Raw Materials
Cosmetics are compound mixtures made of various raw materials through reasonable deployment and processing. Cosmetics have a wide variety of raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: matrix raw materials and auxiliary raw materials.
The former is a kind of main raw material of cosmetics, which occupies a large proportion in cosmetic formulations and plays a major functional role in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other properties to cosmetics, which are not used in cosmetic formulations, but are extremely important. Cosmetics are chemical mixtures made of natural, synthetic or extracted substances with different functions as raw materials and processed through production procedures such as heating, stirring and emulsification.
