To achieve high yield and high efficiency in fisheries, these three measures need to be implemented well
To achieve high yield and high efficiency in fisheries, efforts should be actively made to optimize the ecological conditions for aquaculture and strengthen the construction of supporting pond facilities. Specifically, this can be done from the following three aspects. 1. Implement the renovation of old ponds. The old pond renovation project should follow the requirements of "ecology, circulation, health, and intensification" and carry out major engineering construction such as "desilting and deepening, pond shape transformation, pond embankment slope protection, pond ridge widening and tidying, and improvement of supporting water, electricity, and road facilities," with particular emphasis on removing the thick layer of sludge at the bottom of the pond so that the bottom sediment is reduced to about 20 cm. Through desilting

Three key points for raising fish fry in autumn
Adjust the density and grade the rearing. After the beginning of autumn, choose suitable weather when the temperature is relatively cool, pull a net through the pond to sort the uneven-sized fry, and classify them as large (about 20 cm), medium (about 15 cm), and small (below 15 cm). Large-sized fry can be transferred to larger adult fish ponds with better conditions for mixed culture, while medium and small-sized fry are raised intensively in separate ponds. For stocking density, generally a pond with a water depth of about 15 m is stocked with 3000-5000 fish per mu. Fertilize according to the water condition and feed reasonably. For nursery ponds mainly raising silver carp and bighead carp fry, in addition to

The key "three waterings and three fertilizations" technical points for garlic cultivation
Water and fertilizer management after garlic turns green is the key to a bumper garlic harvest. As the weather warms up, water and fertilizer uptake gradually increases after greening, especially during the bolt-bearing stage and the bulb swelling stage, which are the peak periods of water and fertilizer demand for garlic. Therefore, throughout the entire growth period of garlic, timely watering and topdressing should be carried out according to soil moisture conditions and soil fertility and seedling conditions, with special emphasis on doing well the "three waterings" and "three fertilizations." 1. Water the greening water well and apply the greening fertilizer well. By the Spring Equinox, the garlic seedlings begin to turn green and grow. Because the early spring soil temperature is low, it is best to water the greening water at noon

Key Points of Three-Dimensional Cultivation Technology for Gastrodia elata and Soybean
Gastrodia elata is a traditional Chinese medicinal herb with effects such as benefiting qi, calming convulsions, nourishing the liver and stopping dizziness, dispelling wind-dampness, and strengthening bones and muscles. In recent years, on the basis of artificial box cultivation, we have made full use of the growth characteristics of Gastrodia elata and successfully adopted underground planting of Gastrodia elata with above-ground planting of the short-stalked crop soybean. According to investigation and measurement by the Agricultural Station of Shuidian Town, in three-dimensional cultivation of soybean and Gastrodia elata, the yield of commercial dried Gastrodia elata is 200-300 kg per mu, creating an output value of 8000-10000 yuan (calculated at 36-40 yuan/kg); the yield of soybean is 150-175 kg per mu, creating an output value of 360-

Three key points for high-yield cultivation of Gastrodia elata
In recent years, as the area devoted to Gastrodia elata production has shrunk sharply while market demand keeps rising, the price of Gastrodia elata has shown a continuously upward trend. Recently many growers have called to inquire about cultivation techniques for Gastrodia elata. A reporter interviewed Gastrodia elata expert Professor Cao Debin of the Shandong Academy of Agricultural Sciences on this topic. The key points of high-yield cultivation techniques for Gastrodia elata are introduced here, in the hope of being helpful to the many Gastrodia elata growers. 1. Armillaria must be "three new" 1. New technology: new methods to obtain new strains. The new method uses the latest biotechnology to detoxify the strains, and this is by far the most advanced method of obtaining strains. Among traditional Armillaria strains, those obtained by tissue isolation or spore isolation have the best effect; ordinary units or individuals mostly use purchased mother cultures for subculturing and expansion, so the cultivation effect is poor.

Three key points to master for high-yield Gastrodia elata cultivation
I. Armillaria must be "three new" 1. New technology: new methods to obtain new strains. The new method uses the latest biotechnology to detoxify the strains, which is by far the most advanced method of obtaining strains. Among traditional Armillaria strains, the best results come from those obtained by tissue isolation or spore isolation; most units or individuals use purchased mother cultures for subculturing and expansion, so the cultivation results are poor. 2. New strains: pure isolated strains within three generations are required. The pure isolated strains referred to in this article mean

Three cloned pigs born successfully in Harbin
China's first cloned Northeast Min pig using adult somatic cells as nuclear donors has been born in Harbin. Three adorable black cloned piglets, just three days old, met with the media. This is also China's second successful cloned pig, following China Agricultural University. According to project leader Dr. Liu Zhonghua of the College of Life Sciences at Northeast Agricultural University, the difference between their cloned Northeast Min pig and previous cloned pigs lies in the use of adult somatic cells as nuclear donors; the donor nuclear cells were taken from a 3-day-old Northeast Min piglet

Three Ways with Shrimp
Main ingredients: about two and a half jin of fresh shrimp. Auxiliary ingredients: oyster sauce, fish sauce, cilantro, tomato ketchup, salt. Rinse the fresh shrimp clean with water, take out part of them and remove the shrimp heads, and divide the rest into two plates. First way: salt and pepper shrimp heads. Coat the shrimp heads evenly with dry flour, and pour oil into the wok. Put the shrimp heads into the wok and fry, take them out and let them cool, then fry them in the wok again. Sprinkle with Sichuan peppercorn salt and they are ready to be plated. Features: crispy and fragrant. Second way: blanched shrimp. Pour water into the wok, bring it to a boil, take one plate of shrimp and blanch them in the water, then take them out and arrange

Differences Between Three Soft-Shelled Turtle Diseases and Their Prevention and Treatment Methods
In the process of soft-shelled turtle farming, some farmers cannot clearly distinguish white spot disease, white spot fungus disease and saprolegniasis, and blindly and indiscriminately use drugs when treating turtle diseases, thus affecting the effectiveness of disease prevention and treatment. Therefore, based on recent years of practice at soft-shelled turtle farms, the author summarizes the differences between the above diseases and comprehensive prevention and treatment methods as follows. I. Differences between white spot disease, white spot fungus disease and saprolegniasis in soft-shelled turtles 1. Different pathogens: the pathogen of white spot disease is Aeromonas hydrophila, Aeromonas sobria, etc.; the pathogen of white spot fungus disease is Mucor, which belongs to

Variety Characteristics and Key Cultivation Techniques of the Three-Season Pear
Variety source: The Three-Season Pear originated in France and is preserved by the Dalian Academy of Agricultural Sciences. Characteristics: The crown of the Three-Season Pear is an inverted cone shape; young trees are relatively strongly upright, while mature trees are semi-spreading. In the Dalian region, flower buds break in late March, bloom from late April to early May, and the fruit is harvested in early August. Generally, trees begin bearing fruit 3-4 years after planting and enter full production at 8-10 years, with a yield of 50-100 kg per tree and 3000 kg per mu. It has moderate resistance to black leaf disease, strong insect resistance, moderate cold resistance, and is relatively wind-resistant. The fruit is large, with an average single fruit weight of
