Understanding the definition and classification of fish medicines in one article
A drug refers to a substance used to prevent, treat and diagnose diseases and to help the body restore normal function. As the name implies, a fishery drug refers to a drug specifically used in fisheries to ensure the healthy growth of aquatic animals and plants. Therefore, its scope of application is limited to the aquaculture and enhancement industry, while substances used in capture fisheries and the aquatic product processing industry are not included in the category of fishery drugs. Modern aquaculture fisheries are divided into two major parts: the culture and enhancement of various aquatic animals such as fish, shrimp, shellfish, turtles and soft-shelled turtles, and the cultivation of aquatic plants mainly consisting of algae such as nori and kelp.

How do you prune Schisandra chinensis? First, understand its growth habits
After wild Schisandra chinensis is cultivated artificially in farmland, in order to control tree vigor, avoid excessive overlap of branches and leaves, and prevent branches from tangling with each other, it should be pruned reasonably according to the growth habits of Schisandra chinensis. This makes the fruiting branches evenly distributed on the trellis surface, improves ventilation and light penetration, improves the field microclimate, enhances disease resistance, reduces nutrient consumption, promotes flower bud differentiation, and increases yield. 1. Heading back In the same year of sowing, Schisandra chinensis can grow to about 20 cm, and tall ones can reach more than 30 cm. Regardless of whether the seedling is tall or short, large or small, there should be 2 to 4 plump buds at the base

Key Technical Points for Standardized High-Yield Cultivation of Schisandra chinensis
Schisandra chinensis is a medicinal plant of significant economic value in the Changbai Mountain region. Due to years of damage from human factors, wild resources have been greatly reduced, and reliance on wild resources is far from sufficient to meet the growing demand of the traditional Chinese medicinal materials market, pharmaceutical and processing enterprises. It is imperative to carry out research on domesticating wild plants for cultivation and move toward cultivation. Based on a large number of experimental studies, this achievement for the first time proposes a complete set of high-yield cultivation techniques for Schisandra chinensis, with seedling raising, orchard establishment, training and pruning, soil management, and pest and disease control as the main contents, enabling Schisandra chinensis under artificial cultivation

How to carry out tending and management of dawn redwood? Read this article to understand the key points
Tending should be carried out promptly after afforestation. Watering during April and May is the key to ensuring survival. When planting large saplings, special attention must be paid to drought resistance during the hot season. Weed and loosen the soil two to three times each year, with tending from May to June and from August to September having notable results. After 2 years, applying fertilizer once before spring bud break is very necessary. Generally, pruning is not necessary before the stand is established, but after the stand is established, pruning should be moderate. When the tree height is 6 to 10 m, the pruning height is one quarter to one third of the tree height; when the tree height is 10 to 15 m, the pruning height is one third to one half of the tree height.

Why do pet dogs shed hair? These reasons are something dog owners should understand
First, seasonal shedding. Most dogs shed and change their coat in spring and autumn, such as Shetland Sheepdogs, Chow Chows, Pekingese, and so on.
