Sunflower sunflower blossom
Scientific name: Helianthus annuus
Alias: Sunflower Chaoyang Flower
Because it always grows toward the sun, people call it sunrise.
Family is: Helianthus
Growth characteristics:
Herbs annual, high 1 to 3 meters. Stems erect, stout, round-ovate, hirsute white. Leaves usually alternate, heart-shaped oval or ovoid, apex acute or acuminate, with a basic out of 3 veins, edges with coarse serrations, rough on both sides, coat, long handle. Flower heads, extremely large, 10 to 30 cm in diameter, solitary at the top of the stem or branches, often sloping. The total sepals are multilaminate, leafy, imbricate, obelised, and flowered in summer. The yellowish ray flowers at the inflorescence border are not strong. The middle of the inflorescence is bisexual tubular flowers, brown or purple, strong. Achenes, obovate or ovate-oblong, slightly compressed, fruit skin lignified, gray or black, commonly known as sunflower seeds.
Growth habits:
Sex is warm and drought-resistant.
Adaptable, the soil is not strict. Acid and alkaline soil can all flower. Strong cold resistance, winter without any protective measures can safely winter, in the open air, where the wind does not accumulate snow, with their own stubble cut cover, natural snowfall can guarantee winter.
Xiqiang light, no sunburn phenomenon, open-field cultivation of water once per day for 10 days, hi fat but not excessive, heavy fertilizer although large, but easy to lodging. Transplanting flowers for 4 hours during flowering must be watered without artificial trimming and the crowns are naturally plump.
Origin:
Native to North America, it is cultivated all over the world.
use:
Seeds are extremely oily, fragrant and delicious, can be fried, but also can be pressed, and are important oil crops. There are three types of edible, oil, and dual-use.
Tori, stalks, shells, can be used as industrial raw materials.
Sunflower has many advantages, and is suitable for landscaping and beautification. Especially in the cold north, it is an excellent material worthy of application, such as hedgerows, flower borders, car belts, and groups of parks, squares, courtyards, street gardens, and flower beds.
Catalyst refers to a substance which can change the reaction speed in a chemical reaction and whose composition and mass remain unchanged after the reaction. The catalysts that speed up the reaction are called Positive Cata-lyst and the slower ones are called Negative Cata LYST or moderators. Generally speaking, the catalyst is to correct the catalyst. These catalysts are widely used in industry, especially in organic chemical industry. They are of great significance, for example, catalysts are needed for the preparation of sulfuric acid by contact method, the hydrolysis of synthetic ammonia, esters and polysaccharides, and the hydrogenation of oils and fats. Commonly used catalysts are metals, metal oxides and inorganic acids. If the catalyst is a solid, the reactant is a gas, forming a heterogeneous catalytic reaction, this catalyst, sometimes called a catalyst or contact agent.
Auxiliaries refer to the industrial and agricultural production, especially chemical production, in order to improve the production process, improve product quality and output, or give the product a unique application performance, usually need to add some auxiliary chemicals. It is a kind of important auxiliary raw materials in chemical production, which can give the products special properties and improve the use of finished products, accelerate the chemical reaction speed and improve the yield of products, save raw materials and improve the processing efficiency. It is widely used in chemical industry, especially in organic synthesis, synthetic material processing and petroleum refining, pesticides, pharmaceuticals, dyes, coatings and other industrial sectors. By use, it can be divided into synthetic auxiliaries and processing auxiliaries. Auxiliaries used in the synthesis and polymerization of resins, fibers, rubber and other monomers are called synthetic auxiliaries, including catalysts, initiators, solvents, dispersants, emulsifiers, polymerization inhibitors, regulators, terminators, etc. Auxiliary chemicals used in the manufacture of rubber, plastic products and in the spinning and spinning of chemical fibers are called processing aids, including plasticizers, heat stabilizers, antioxidants, light stabilizers, flame retardants, foaming agents, lubricants, demoulding agents, vulcanizing agents, accelerators, softeners, anti-scorching agents. Agents, surfactants, oils, fillers and so on. Many of these Additives are dangerous chemicals, such as diphenyl peroxide, azodiisobutyronitrile, hydrogen peroxide-ferrous blue, alkyl aluminum, titanium chloride and other initiators, catalysts are inflammable and explosive materials, should be stored and transported in accordance with the relevant provisions of the Regulations on the Safety Management of Chemical Hazardous Goods. Management and use.
