  • Golden trout is a new variety first developed in China

    The Yongchang County Golden Trout Breeding and Propagation Base is located in Jiaojiazhuang Township, 10 kilometers west of Yongchang County town. The entire township is rich in spring water resources, with springs flowing continuously throughout the year. The water quality is excellent, rich in strontium, lithium, zinc and various other minerals beneficial to human health, with no harmful elements and no pollution whatsoever, making it a purely natural treasure. The water quality and water temperature are very suitable for the growth of cold-water freshwater fish. At present, the township has built 1 Yongchang Golden Trout Breeding and Propagation Center, with 6 specialized golden trout farming households, more than 200 broodstock, over twenty thousand large-size fingerlings

  • What are the responses of soybean growth and development to light?

    Soybean is a short-day crop, with a daylength range of 9-18 hours. The shorter the light, the more it promotes flower bud differentiation and advances flowering and maturity. When soybean grows its first compound leaf, it begins to respond to light. Generally, seedlings can complete the light stage after 5-12 days of short-day conditions. The appearance of flower calyx primordia on the plant marks the completion of the light stage. Due to long-term adaptation to light conditions in different regions, the short-day response of soybean varies considerably. Southern soybean varieties have a stronger short-day response, while northern soybean varieties are insensitive to daylength, so special attention should be paid when introducing varieties.

  • What are the temperature requirements for soybean growth and development?

    Soybean is a warmth-loving crop, and the accumulated temperature required by soybean varieties in Heilongjiang Province is about 1800-2700°C. (1) The optimum temperature for seed germination is 18-20°C, at which germination is fast and seedlings emerge evenly; the minimum temperature is 6-8°C, but germination is very slow; when the temperature reaches 33-36°C, germination is fastest, but the seedlings are weak. (2) The minimum temperature required for emergence is 8-10°C. (3) For flower bud differentiation, 21-23°C is more suitable. For flowering, 22-25°C is more suitable. If the temperature is too high or too low, there will be fewer flowers. (4) The suitable

  • What nutrients are essential for soybean growth and development?

    Soybeans require large amounts of nutrients in many different forms. For the same yield, soybeans need 4-5 times more nitrogen than cereal crops. The main nutrients they require are the three major elements nitrogen, phosphorus and potassium, followed by 9 trace elements including calcium, magnesium, sulfur, magnesium, boron, molybdenum, manganese, zinc and copper.

  • Key Technical Points in the Research and Development of Seasoned Mushroom Snacks

    Seasoned mushroom snack series are among the newest leisure plant-based products. In particular, plant-based seasonings like mushroom snacks have become the reason many consumers favor this new food source of plant products, and the market has remained bullish. Drawing on years of experience in researching compound seasoned foods, we now specially offer the research and development techniques for related seasoned mushroom series products, such as seasoned shaggy mane mushroom (Coprinus comatus), seasoned enoki mushroom (Flammulina velutipes), seasoned tea tree mushroom (Agrocybe aegerita), seasoned shiitake mushroom (Lentinula edodes), seasoned matsutake (Tricholoma matsutake), and seasoned bolete (Boletus spp.), for everyone's reference and inspiration. 1. Processing workflow for seasoned mushrooms: mushrooms to trimming to preservation to

  • What new trends are emerging in the development of peach varieties in China?

    The market development trends have the following characteristics: white-fleshed juicy peaches still hold the mainstream position. In peach cultivation in China, white-fleshed juicy peaches account for more than 70%. Currently on the market, the main varieties are "Feicheng Peach", "Wuyuexian", "Chunlei", "Yuhualu", "Shazizaosheng", "Baifeng", "Okubo", and others. Due to the influence of many factors such as fruit flavor, productivity, storage and transportability, and cultivation area, the market prices of these varieties have dropped substantially in recent years. With the introduction of some new varieties, current orchard establishment mainly selects excellent varieties with larger fruit

  • Detailed Explanation of the Development Process for Golden Sun Apricot Jam

    Golden Sun apricot is a European apricot variety introduced by the Shandong Institute of Pomology in 1993. The fruit surface is smooth, the background color is golden yellow, and the sunny side has a red blush, making the fruit color very attractive. The flesh is yellow, fine and juicy, with few fibers, containing 14.7% soluble solids, 13.1% total sugar, and 1.1% titratable acid. The average single fruit mass is 70g, the stone is free, and the edible rate reaches 96.8%. The fruit matures at the end of May and has the ability to set fruit parthenocarpically. It is early-bearing, high-yielding, and stable-yielding, and is resistant to pests and diseases with strong adaptability. In view of Golden Sun

  • Rice direct seeding machine successfully developed, efficient and versatile, boosting rice sowing

    Recently, a "Multifunctional Soil-Covering Direct Seeding Machine Rice Mechanical Direct Seeding Field Demonstration" organized by the China National Rice Research Institute was held in Buqiao Village, Fuyang City, Zhejiang Province, with more than 40 experts from home and abroad attending the field observation event. In recent years, China's rice mechanical transplanting technology has developed rapidly, and a number of different types of transplanters suited to China's rice production have been developed and produced. However, the development and research of rice direct seeding machines and mechanical direct seeding technology have lagged relatively behind, and no mainstream rice mechanical direct seeding technology has yet taken shape. To overcome the problems of poor seedling establishment, easy lodging, premature aging, and difficult and costly weed control

  • Purple-marked rice male sterile lines developed in Guangxi

    The rice male sterile lines carrying the purple-leaf marker trait, Xianhong A and Zhihong A, developed by the research team led by Guangxi Outstanding Expert Researcher Liang Shirong and Guangxi Academy of Agricultural Sciences Vice President Researcher Deng Guofu, passed the field technical appraisal organized by the office of the Guangxi Regional Crop Variety Approval Committee and conducted by a relevant expert group on August 3, 2007. After strict field investigation and indoor microscopic examination, and after hearing the research team's technical report and answers to questions, the expert group unanimously concluded that Xianhong A and Zhihong A have stable agronomic traits, stable male sterility, and good flowering

  • Analysis of the problems existing in the development of the eel industry and the countermeasures and suggestions

    I. Seedlings and fingerlings The main species farmed for eel in China are the Japanese eel (Anguilla japonica) and the European eel (Anguilla anguilla). The resources of both the European eel... have already approached exhaustion, with annual production falling from 3,000 tons 30 years ago to 100-200 tons. From June 3 to 15, 2007, at the Conference of the Parties to the "Washington Convention" (CITES) held in the Netherlands, the European eel was listed in Appendix II of the Convention on Endangered Species of Wild Fauna and Flora, and this will be formally implemented starting in January 2009: China imports about 60 tons, or about 150 million individuals, of European eel seedlings and fingerlings annually, and farmed European eel accounts for more than 1/3 of eel production, while European eel accounts for about 40% of exported roasted eel. Japanese eel resources have also severely declined. In recent years, the seedling and fingerling resources of Japanese eel in Asia have remained at about 100 tons, and the annual catch in recent years has remained at 80-100 tons. In 2008, the output of European eel seedlings and fingerlings was about 90 tons, half of a normal year. The output of Japanese eel seedlings and fingerlings was about 35 tons, one third of a normal year. The severe shortage of seedling and fingerling resources has led to soaring prices. Moreover, artificial breeding of eel seedlings and fingerlings will not be able to form production capacity in the near future.
