Jiaying Koi and Brocade Crucian Carp: Introduction to High-Quality Fish Species
Jiaying Koi and Brocade Crucian Carp are the flagship products of the Meizhou Fisheries Research Institute. As early as the 1980s, the institute's researchers carefully bred these two new varieties through crossbreeding methods. Jiaying Koi is divided into eight major strains: long-finned, red-and-white, golden-yellow, light-yellow, black, white-jade, scattered-scale, and purple, with nearly a hundred color varieties. They are colorful, slender and graceful, crystal-clear and gorgeous, with charming elegance. Their long and soft fin rays are their greatest feature, floating lightly and captivatingly, whether bold and martial,

To raise high-quality fish, adhere to the four-fixed feeding method
Fixed quality means the feed given must be fresh and palatable, not rotten or spoiled, nutritious, and easily digested and absorbed by the fish. Grasses must be disinfected, manure must be fermented, and hard, coarse feed must be chopped or processed. For the fixed quantity, the monthly feeding amount should be determined according to water temperature, fish growth and feed supply. The daily feeding amount depends on the season, water color, weather and the feeding situation of the fish, and is generally calculated at 2%-5% of the fish stock in the pond. It can also be determined according to how the fish eat; for example, if grass is fed at 8-9 a.m.,

Scientific and technological leadership brings high returns in silver carp farming
Grow-out fish (market-size commercial fish) farming is the ultimate goal and purpose of fish farming. In recent years, although special aquatic product farming has become "hot" across the country, the traditional farming and consumption of silver carp and bighead carp remain bulk commodities, and the economic returns are still considerable. They have the advantages of small investment, quick results, easy operation, abundant seed sources, and mature production, and are very popular among fishermen. The production process and technical key points mainly use the intensive culture method of "water, seed, feed, density, polyculture, rotation, prevention, and management." 1. Pond conditions: area 0.3-1.4 hectares, clay or loam bottom soil is preferable

A Highly Effective Method of Using Mirabilite to Treat Pig Eczema
Eczema is a skin disease that occurs frequently in pigs in autumn. Acute and chronic eczema has the main symptoms of erythema, papules, and itching on the skin, and a few cases are accompanied by pustules, exudate, erosion, and scabbing, and it is especially harmful to suckling piglets. Based on practical experience in production, treatment with mirabilite has a highly effective result. Method: according to the size of the pig and the area of the affected part, take 50-200 grams of mirabilite respectively, add 200-500 milliliters of cold boiled water, and after dissolving, apply and rub the affected part, 4-5 times a day, or use a clean towel to dip the liquid and wipe the affected area, for half an hour each day,

Detailed Explanation of Key Techniques for Tea Cultivation in High Mountain Areas
Datian County has over 20,000 mu planted in high mountain areas at an altitude of 800-1,100 m. This region has an annual average temperature of 17.5°C, annual rainfall of 1,770 mm, large day-night temperature differences, abundant cloud, mist and dew, and high humidity. The annual picking period starts 7-10 days later than the low-altitude tea areas in the county, and autumn tea ends about 7 days earlier. Therefore, the following technical points must be mastered in production and cultivation. I. Seedlings 1. Variety selection: choose varieties with strong cold resistance, drought resistance and pest and disease resistance, favorable to market competition and cultivation direction,

High-yield Cultivation Techniques for Lingzhi (Ganoderma lucidum) Grown on Sterilized Linden Wood Logs
I. Production Season: Based on the suitable temperatures for the growth of lingzhi mycelium and fruiting bodies, in both northern and southern regions, wood can be felled in early December of the lunar calendar, cut and bagged in mid-December, sterilized, and inoculation completed by late December. Around Qingming (Tomb-Sweeping Day) of the following year, the logs are buried in the field, and 2-3 batches of lingzhi can be harvested that same year. However, felling must not be later than Qingming, because wood felled after Qingming has high moisture content, the bark tends to fall off, and nutrient loss makes it unsuitable for production. Logs inoculated around Qingming can only produce 1-2 batches of lingzhi that year. II. Wood Requirements: All tree species suitable for log cultivation of shiitake mushrooms and wood ear mushrooms can be used

Key Techniques for High-Yield Oyster Mushroom Cultivation in Summer
In recent years, oyster mushroom production in Beiyang Village, Wangdu County, Baoding City has developed rapidly. However, the summer heat and high humidity, along with the rapid spread of pests and diseases, have created great difficulties for oyster mushroom production. The author believes that summer production should focus on the following points: 1. Strain selection. Choose varieties that are heat-tolerant, have good mushroom shape, high yield, and strong disease resistance. Such as: Hainan No. 2, Chuncai No. 1, He's 200, etc. 2. Ingredient treatment. Appropriately reduce nitrogen fertilizer usage. Appropriately increase gypsum usage. 3. Pile fermentation. Minimize factors that cause poor ventilation. Well-fermented

How to control humidity for higher yields when growing oyster mushrooms indoors?
When growing oyster mushrooms indoors, humidity control is the key to success, and management after fruiting begins is especially important. At this stage, if the humidity is too low, the mushrooms will shrivel, stop growing, or even die; if the humidity is too high, the mushrooms rot easily. Practice has shown that controlling humidity by spraying water is hard to master, and sometimes spraying too heavily on the surface of the substrate affects the development of mushroom buds, causing young mushrooms to die and reducing or even wiping out the harvest. Here is a clever method that controls humidity without spraying water and can also increase oyster mushroom yields. Get some cotton cloth and a jar, cut the cotton cloth into a strip 8 cm x 40
