Chrysanthemums are widely distributed across five continents, with a significant presence in China, spanning from north to south and east to west. These flowers are commonly found in provinces such as Anhui, Zhejiang, Henan, Hebei, Hunan, Hubei, Sichuan, Shandong, Shaanxi, Guangdong, Tianjin, Shanxi, Jiangsu, Fujian, Jiangxi, and Guizhou. While they grow naturally in these regions, some varieties are cultivated, particularly in Anhui, Zhejiang, and Henan. For example, Juju is mainly produced in Qixian and Guoyang in Anhui; Qiju is grown in Quanjiao and Qixian; Gongju comes mostly from Qixian; and Chrysanthemum is primarily cultivated in Tongxiang, Haining, Jiaxing, and Huzhou in Zhejiang. Other notable production areas include Wulu, Luyi, Fuyang, and Boai in Henan, Anguo, Xinji, and Anping in Hebei, Zhongjiang, Cangxi, Yilong, and Kaijiang in Sichuan, Pucheng and Dagu in Shaanxi, Wuchuan, Chenghai, and Lien County in Guangdong, among others.
In China, four types of chrysanthemums are recognized for their medicinal value: Juju, Qiju, Gongju, and Chrysanthemum. Cultivating chrysanthemums can be highly profitable, especially when proper techniques and conditions are followed.
Before planting, it's essential to select the right variety based on regional climate and growth requirements. For instance, Chunju typically blooms from late April to mid-May in East China and late May to mid-June in North China. It is not very sensitive to daylight but thrives at night temperatures around 10°C. On the other hand, Chrysanthemum (often confused with other varieties) is heat-tolerant but not ideal for southern Jiangsu due to summer high temperatures that may cause bud deformation. Early autumn chrysanthemums bloom from late September to early October, while late autumn varieties flower from mid-October to mid-November. In South China, winter chrysanthemums bloom after December, requiring additional protection like plastic covers or heating in northern regions.
Soil preparation is crucial for successful cultivation. The soil should be loose, well-drained, nutrient-rich, and free from pests. Organic and inorganic fertilizers are applied depending on local conditions, aiming to meet the plant’s nutritional needs without over-fertilizing. Greenhouse setups must ensure sufficient sunlight, good drainage, and ventilation, along with auxiliary equipment like shade nets, support structures, and irrigation systems.
Planting methods vary, including single-stem and multi-stem approaches. Proper spacing and depth—typically 3–4 cm—are important for healthy root development. After planting, watering is necessary to settle the roots.
Once established, regular care includes soil and water management, temperature and light control, and pruning to promote better air circulation and light exposure. Each type of chrysanthemum has specific requirements, such as longer days for summer varieties or shorter days for autumn ones. Support structures are often needed to prevent lodging, and timely removal of weak branches helps maintain plant health and productivity. With careful attention, chrysanthemum cultivation can yield high-quality flowers suitable for both ornamental and medicinal use.
Anti Coccidiosis Drugs
Anti-coccidiosis drugs are used to prevent and treat coccidiosis, a disease caused by a protozoan parasite that affects the intestinal tract of animals. Coccidiosis is a common and costly disease in livestock, particularly in poultry, sheep, and cattle.
There are several types of anti-coccidiosis drugs available, including ionophores, chemical coccidiostats, and natural coccidiostats. Ionophores are a class of antibiotics that are commonly used in poultry and are effective against a range of coccidia species. Chemical coccidiostats are synthetic compounds that are added to feed or water and work by interfering with the metabolism of the coccidia parasite. Natural coccidiostats are plant extracts or essential oils that have anti-coccidial properties.
It is important to use anti-coccidiosis drugs in poultry responsibly to prevent the development of drug-resistant strains of coccidia. This can be achieved by rotating different classes of drugs, using them at the recommended dose and duration, and ensuring good management practices to reduce the risk of infection.
