Petunia
Aliases: Petunia, hybrids
Scientific Name: Petunia hybrida
Family & Genus: Solanaceae, Petunia
Life Cycle: Perennial herbs, often cultivated as annuals for one or two seasons. Prefers warm climates and is sensitive to cold. Optimal growth temperature ranges between 15-20°C. Thrives in full sunlight. Avoid overwatering, as they prefer well-drained sandy soils. Flowering period typically lasts from April through October.
Propagation: Can be done through seeds or cuttings. Sowing is best done in spring or autumn. Since the seeds are small, there's no need to cover them with soil after sowing; instead, place a glass or plastic cover to maintain warmth. Germination usually occurs within 4-5 days at temperatures of 20-22°C. After seedlings emerge, keep the temperature around 9-13°C. Double-flowered varieties may not produce true-to-type plants from seeds, so cuttings are often preferred. Cuttings can be taken in spring or autumn and typically root within 15 days under temperatures of about 20°C.
Cultivation: Ensure regular watering and fertilization during the growing season, but avoid over-fertilizing—especially with nitrogen-rich fertilizers—which can lead to leggy growth and weak stems. Prune regularly to maintain an attractive shape and encourage more blooms.
Pests & Diseases: Relatively resistant to pests and diseases, making them easy to grow even for beginners.
Applications: There are numerous horticultural varieties of petunias. They can be categorized by plant type into tall-growing, dwarf, tufted, and trailing types. By flower shape, they include large blooms, single, double, ruffled, and fringed varieties. In terms of color, they come in shades of purple, bright red, pink, blue-violet, white, and multi-colored combinations. Petunias are ideal for indoor planting, hanging baskets, or garden beds, adding vibrant color to any space throughout the summer months.
Also known as electronic chemical materials. Generally refers to the electronics industry uses specialized chemicals and chemical materials, that is, electronic components, printed circuit boards, industrial and consumer production and packaging of various chemicals and materials. It can be divided into substrates, photoresists, electroplating chemicals, packaging materials, high purity reagents, specialty gases, solvents, pre-cleaning dopants, flux masks, acids and etchants, electronic adhesives and auxiliary materials Other categories. Electronic chemicals with many varieties, high quality requirements, small dosage, demanding on the cleanliness of the environment, product replacement fast, large capital investment, higher value-added products, etc., these characteristics with the development of micro-processing technology more and more obvious.
Electronic chemicals, also referred to as electronic chemical materials, refer to the fine chemical materials that are used in the electronics industry. The electronic chemicals are a kind of special chemicals. As far as the properties of the production process are concerned, they belong to the fine chemical industry. In terms of product use, Belongs to the electronic material industry. According to the classification standard of China's national economy, the electronic chemicals industry belongs to "Specialized Chemical Products Manufacturing Industry" (2662); according to the "Guidelines for Industry Classification of Listed Companies" promulgated by China Securities Regulatory Commission in April 2001, it belongs to "Specialized Chemical Products Manufacturing Industry" C4360 ). They include integrated circuits and discrete device chemistries, such as chip production photoresist, ultra-clean high-purity reagents, ultra-clean high purity gas, plastic packaging materials; color TV with chemical materials, such as color phosphor, CPT Supporting the water-soluble resist, high-purity inorganic salts, organic films, etc .; chemical materials used in printed circuit boards, such as dry film resist, ink, chemical and electroplating copper plating solution and its additives, surface mount process conductive paste , Cleaning agents, liquid solder resist photoresist, adhesive patch, conductive adhesive, solder paste, pre-coated flux, clean and water-based process flux; liquid crystal display devices with chemical materials, such as liquid crystal, photoresist , Oriented films, adhesives, slurries, electrolytes, films and encapsulants, polarizers, etc .; polishing materials, ect.
