Broccoli is also called broccoli. Its edible part is green curd, which is rich in nutrients. It is the best vegetable among cabbage vegetables. Now it is mostly used for health care. Because of its strong disease resistance, it is now used by farmers. Friends have grown extensively, so what cultivation and management techniques are there for broccoli? Let's get to know it together!
Broccoli cultivation and management techniques
1. Site preparation
Generally, before planting, it is necessary to turn over the land, dig a suitable planting hole, and apply 1500 kg of decomposed farmyard manure per mu and about 50 kg of compound fertilizer, and mix it with the soil evenly.

2. Cover film
In order to retain water, fertilizer, heat, and inhibit weed growth, it is necessary to cover with a film, and then press the edge of the film with soil blocks.
3. When planting, punch a hole in the mulch above the pond, plant the seedlings, and cover the joint between the root neck of the seedling and the mulch with soil. Then pour enough root water to help survive.

4. Planting management
(1) Topdressing: Broccoli requires a large amount of fertilizer. Nitrogen fertilizer is applied at the seedling stage to promote vegetative growth, and fertilization is controlled in the mid-term to prevent excessive growth. In the later stage, the ball fertilizer is heavily attacked to promote flower bulb hypertrophy.
(2) Moisture: The growth of broccoli needs to keep the soil moist. Generally, watering is done after top dressing. Only by controlling the water supply can the broccoli balls expand more and increase the yield.
(3) Main diseases and insect pests and control technology: Broccoli has strong disease resistance, and the pest damage is not serious. The common diseases and insects are: downy mildew, soft rot, diamondback moth, cabbage caterpillar, and vegetable aphid.
Diseases: downy mildew can be found in the early stage, and black rot can be easily prevented in the later stage. Baijunqing, Dixon, and hydration can be used to prevent and control. If the disease occurs later, it will seriously threaten the quality of broccoli, so it is necessary to spray Streptomyces sulfate Vegetarian for prevention and treatment.
Insect pests: The common pests are Plutella xylostella, Pieris rapae, and Aphid, which need to be sprayed alternately by the farmers with Diazepam, Acetamiprid and Diaosijing.

API Powder is fully defined in ICH Q7A as any substance or mixture of substances intended for use in the manufacture of pharmaceutical products and, when used in pharmaceutical products, as an active ingredient of pharmaceutical products. Such substances have pharmacological activities or other direct effects in the diagnosis, treatment, symptom relief, management or prevention of disease, or can affect the function or structure of the body. The active ingredient of a medicine. Only when an API is processed into a pharmaceutical preparation can it become a medicine for clinical application.
According to its source, apis are divided into chemical synthetic drugs and natural chemical drugs.
Chemical synthetic drugs can be divided into inorganic synthetic drugs and organic synthetic drugs. Inorganic synthetic drugs are inorganic compounds (very few are elements), such as aluminum hydroxide and magnesium trisilicate for the treatment of gastric and duodenal ulcer, etc. Organic synthetic drugs are mainly made of basic organic chemical raw materials, through a series of organic chemical reactions and drugs (such as aspirin, chloramphenicol, caffeine, etc.).
Natural chemical drugs can also be divided into biochemical drugs and phytochemical drugs according to their sources. Antibiotics are generally produced by microbial fermentation and belong to the category of biochemistry. In recent years, a variety of semi-synthetic antibiotics are the combination of biosynthesis and chemical synthesis products. Among apis, organic synthetic drugs account for the largest proportion of variety, yield and output value, which is the main pillar of chemical pharmaceutical industry. The quality of the API determines the quality of the preparation, so its quality standards are very strict. All countries in the world have formulated strict national pharmacopoeia standards and quality control methods for the widely used APIS.
Specific API after processing -- pharmaceutical preparations
The term API is used mainly in relation to the finished product. Mainly raw materials obtained by chemical processing means, supply raw materials for the production of finished drugs. For example, cefpirome sulfate for injection is a drug, then cefpirome sulfate is an API
