  • Processing Methods and Technical Key Points for Pickled Jerusalem Artichoke

    Jerusalem artichoke, botanically known as Helianthus tuberosus, is a plant of the Asteraceae family. It can be used to produce health food with a unique flavor. 1. Process flow: raw material processing → sun-drying → initial pickling → removal of brine → second pickling → slicing → rinsing → seasoning → sterilization. 2. Processing key points. 1. Raw material pretreatment: First wash the raw materials with clean water, discard impurities and rotten, damaged, spoiled, or moldy tubers, rinse again with clean water, then place in a bamboo basket to drain. 2. Sun-drying: Spread the rinsed clean raw materials on a bamboo rack or clean cement slab, spread them evenly and thinly, and let them dry in direct sunlight. Turn them once in the morning and once in the afternoon until they feel soft when squeezed by hand; generally dry for 2 days.

  • Prevention and Control Methods and Technical Key Points for Porcine High Fever Syndrome

    "Porcine unknown high fever," also known as porcine high fever syndrome, is a disease with high morbidity and mortality rates, occurring mainly in growing-finishing pigs and some sows. The main clinical manifestations in affected pigs are elevated body temperature, depression, loss of appetite or complete anorexia, difficulty breathing, panting, with some pigs showing symptoms such as reddened to purplish skin, and a few having hemorrhagic spots at the hair follicles. The pathogens are mainly mixed infections and secondary infections involving multiple viruses, bacteria, and parasites, including classical swine fever virus (HCV), porcine reproductive and respiratory syndrome virus (PRRSV)

  • Analysis of Key Technical Points for Increasing the Yield of High-Grade Tea

    With the development of our country's economy, the improvement of people's living standards, and the continuous deepening of opening up to the outside world, high-grade tea is increasingly favored by the market, and its sales volume is growing year by year. Therefore, how to increase the yield of high-grade tea has become an important research topic in tea production. To this end, the author conducted technical explorations in many aspects, gained some experience, and achieved good results. The main steps are introduced as follows; 1. Strengthen autumn and winter fertilization of tea gardens. In winter, apply sufficient base fertilizer and additional quick-acting nitrogen fertilizer, giving full play to the spring effect of fertilizers, so that spring tea is high-quality

  • Key technical points for autumn and winter management of mulberry trees, tea trees and fruit trees

    I. Winter management of mulberry fields Doing a good job of winter management of mulberry fields lays a solid foundation for the growth of mulberry trees in the coming year and is also an important measure for increasing the yield and quality of mulberry fields. 1. Clearing the field: After the mulberry leaves fall, collect all the residual leaves and weeds in the mulberry field to make compost or burn them, so as to eliminate pathogenic bacteria and overwintering pests hidden in the mulberry leaves and weeds. 2. Bundling: Before winter plowing, use rice straw to bundle the mulberry branches together, which not only facilitates winter plowing and fertilization, but also lures pests to hide in the bundled straw to overwinter, making it easier to capture and kill them. 3. Winter plowing: Control the plowing depth at

  • Harvesting, Processing Methods and Technical Key Points for Pinellia ternata

    Those propagated from tubers are harvested in the same year or the following year, while those propagated from seeds can only be harvested in the 3rd to 4th year. Harvesting is generally carried out in summer and autumn after the stems and leaves have withered and fallen over. After digging them out, pack them in baskets, wash off the mud and sand while they are still fresh, put them into gunny sacks and rub off the outer skin, then pour them out and wash the outer skin clean with clear water. Scoop them out and dry them in the sun to obtain Pinellia ternata. Generally, the yield of fresh tubers is 500-750 kg per mu, and the drying ratio is about 30%.

  • Key Technical Points and Detailed Methods for Block Cultivation of Nameko Mushroom

    Nameko mushroom, also known as Pholiota nameko, is a low-temperature wood-rotting edible fungus. It contains nutrients such as protein, fat, carbohydrates, and amino acids. When eaten fresh, its flesh is tender and its flavor is delicious. At the same time, nameko polysaccharides have a certain inhibitory effect on tumors. Therefore, nameko is a fungus with both edible and medicinal value. The key technical points for nameko cultivation are briefly described as follows. 1 Growth and development conditions 1.1 Temperature The optimum temperature for the mycelial stage is 20-24°C. During the fruiting stage, different temperature-type varieties have different fruiting temperature requirements. Early

  • Detailed Explanation of the Cultivation Methods and Technical Key Points for Spray Chrysanthemums

    The public appreciates chrysanthemums, enjoying a plant with three to five blooms, with a graceful and swaying posture, fresh and lively; they love to see three branches and nine tops, with clusters of blossoms, symbolizing "three abundances and nine tops," embodying traditional folk customs. 1. Variety selection: oriented toward popular preference, choose varieties with wide adaptability, strong stress resistance, moderate plant type, upright stems, uniform leaves, full flower form, brilliant flower colors, and long-lasting flowering period. It is better to have few but fine varieties, and do not choose rare late-blooming or difficult-to-grow varieties. 2. Mother plant maintenance: In the Beijing area, the perennial roots of mother plants can overwinter in the open field or in a sun frame.

  • Detailed Explanation of the Cultivation Methods and Technical Key Points for Single-Stem Chrysanthemums

    Golden autumn is the season for admiring chrysanthemums, and among ornamental chrysanthemums, single-stem chrysanthemums are the finest. To cultivate single-stem chrysanthemums, the following steps must be done well: Select a plant with excellent flower shape, flower color, and plant form, as well as a vigorous plant that has already flowered, as the mother plant, and strengthen the care of the old roots. To ensure the health of the next generation of cuttings, spray 500-800 times diluted chlorothalonil or carbendazim once every 2 weeks before harvesting cuttings. Take vigorous young shoots from the second or third generation as cuttings. Cuttings are best taken from late May to mid-to-late June. Choose a seedling pot or an eggshell clay pot as the

  • Key Technical Points for Interplanting Small Shrubs in Southern Magnolia Fields

    In the first 3 years of southern magnolia (Magnolia grandiflora) seedling growth, to offset the drawbacks of large initial investment and no profitable output from field-planted trees in the early stage, small shrubs such as Japanese boxwood (Buxus microphylla), golden privet (Ligustrum sinense 'Variegatum'), and red-leaf barberry (Berberis thunbergii) can be interplanted. During the first 3 years of interplanting small seedlings, at 6000-7000 plants per mu, averaging 0.5 yuan per plant, a return of over 3000 yuan can be obtained. After the 4th year, the southern magnolia has grown to 5-6 cm, and can then be sold selectively at about 80 yuan per plant. From then on, annual sales all generate income. Cultivation points: when planting 1-year-old southern magnolia seedlings, plant spacing 1.

  • Rearing Methods and Technical Key Points for Squabs and Young Pigeons

    In the initial stage, squabs are best fed fine-particle softened feed. This feed is prepared by crushing corn, mixing it with rice and beans, soaking it in clean water for 2 to 3 hours, and drying it before feeding. The health grit must contain a complete range of trace elements. Some multivitamins can be added to the drinking water. Set up a brooding bed, and pay attention to keeping warm, blocking wind, and keeping dry; generally, they are raised in the brooding bed for about 20 days. Squabs at 50 days of age begin to molt; at this time they are sensitive to external climate changes and prone to illness, so work on cold protection and warmth must be done well. Add some
