Detailed Explanation of the Processing Methods and Technical Key Points for Crystal Jujubes
1. Material selection: Choose fresh jujubes harvested at the white-ripe or crisp-ripe stage as the raw material, ones that are free from damage, free from insect borers, free from wrinkles, uniform in size, and moderate in size. 2. Peeling: Add an appropriate amount of 7%-8% alkaline water solution to a pot resistant to alkali corrosion, heat to boiling, pour the fresh jujubes into the pot, and cook while stirring for 3-5 minutes. When the skins turn brown, immediately scoop them into a vat of 6% dilute sulfuric acid aqueous solution for acid-base neutralization for 10-15 minutes. When neutralized to pH 6-7, scoop out the jujubes, wash them clean with water

Prevention and Treatment Methods and Key Technical Points for Common Diseases in Foxes and Raccoon Dogs
From July to September, breeding foxes and raccoon dogs enter the recovery period, and the young enter the growing period. The common diseases in this period are mainly the following. (1) Heatstroke (sunstroke and heat exhaustion) This disease occurs in the midsummer season, when the temperature is too high and ventilation is poor, and the animal is exposed to direct sunlight, causing brain overheating (sunstroke) or the whole body being stimulated by heat (heat exhaustion). It usually occurs rapidly, and the mortality rate is very high. Foxes and raccoon dogs have extremely underdeveloped sweat glands and dissipate body heat slowly, making it very easy for their body temperature to rise, with listlessness, staggering

Force-feeding methods and technical key points for meat-type squab
Meat-type squab at 18 to 25 days of age can reach a body weight of 350 to 500 g, and depending on the situation can be considered ready for market. However, at this time the squab meat has a relatively high water content and little subcutaneous fat. To improve the quality of the pigeon meat, force-fattening can be carried out for 5 to 7 days before sale. After force-fattening, the squab is crisp-skinned, tender-boned and flavorful after cooking. 1 Squab selection: Squab from 10 to 25 days of age can all be force-fattened. Most often, squab at 15 to 20 days of age with a body weight of 350 to 500 g are used for fattening

Key Technical Points for the Prevention and Control of Pseudomonas Infection in Mink
Pseudomonas infection in mink, also known as mink Pseudomonas aeruginosa infection or mink hemorrhagic pneumonia, is an acute infectious disease of mink caused by Pseudomonas aeruginosa of the genus Pseudomonas. The disease is characterized by difficulty breathing, hemorrhagic pneumonia changes and pulmonary edema, and hemorrhagic pathological changes in organ tissues, and often occurs as an endemic. 1. Pathogen The pathogen of this disease is Pseudomonas aeruginosa, also known as Pseudomonas aeruginosa, which is widely present in nature, and exists in animal feces, water and sewage. Gram-stain negative. Cultured on ordinary medium, it can produce yellow-green pigment, hence the name Pseudomonas aeruginosa.

How are tulips cultivated and managed? These technical points need to be mastered
1. Preparation before planting First check whether the tulip bulbs have pests or diseases. If they are already infected or beginning to rot, they must be removed and burned. After removing diseased bulbs, soak the bulbs in a fungicidal solution for disinfection, for example, soak in a 600-fold chlorothalonil solution for 20-30 minutes. Around mid-August, cut open 3-4 tulip bulbs and observe the development of the internal nose (that is, the already differentiated flower stem). Those with a nose 3-4 mm long, ivory-colored and firm are good; whitish ones are not considered good, and flat ones are also not ideal. Choose a humus-rich

Tulip Post-Harvest Handling Methods and Technical Key Points
Flower growers tend to focus their attention on cultivating high-quality products, but they are less concerned about harvesting and post-harvest handling. This makes their earlier work lose its value. For this reason, this article was written. Harvesting colored buds When the harvest season arrives, the plant has stored nutrients in its stem for use in flowering. If harvesting is done before the plant is sufficiently mature, then the nutrients stored in its stem are insufficient, and it will be impossible to bring the expected results to future consumers. By using the method of harvesting with the bulb attached,

Key Technical Points for High-Efficiency Cultivation of Straw Mushrooms in Winter
Straw mushrooms (Volvariella volvacea) are a high-temperature, high-humidity type of fungus, suited to growing in an environment of constant temperature and stable humidity. The suitable growing temperature for straw mushrooms is 23-25°C, and the relative air humidity is 85%-95%. Therefore, to move the high-temperature straw mushroom to cultivation in the lower temperatures of winter, it must be grown in greenhouses with good insulation capacity, which increases cost inputs such as heating. Moreover, straw mushrooms produced in winter sell for 2 times the price of those from conventional summer cultivation, so appropriate adjustments should be made in aspects such as the culture material formula and cultivation management, in order to

How to carry out field management of Polygonatum? Detailed explanation of the technical key points
(1) Intertillage and weeding: After emergence, weeding should be carried out frequently, especially during the seedling stage of sown fields, where timely weeding is even more necessary to prevent large weeds from overwhelming the seedlings and affecting growth. (2) Thinning and final thinning: When the seedlings are 5-8 cm tall, remove the overly dense small seedlings; before withering in autumn or after emergence the following year, carry out final thinning at a plant spacing of 8-10 cm. Take the thinned seedlings to a different location for transplanting. (3) Drought prevention and drainage: Polygonatum prefers moist soil. In dry weather, water promptly to keep the soil moist; in the rainy season, ensure good drainage to avoid water accumulation in the field and prevent root

Methods and Technical Key Points for Pest and Disease Control in Polygonatum (Solomon's Seal)
Diseases include black spot disease, in which irregular yellowish-brown spots appear on the leaves starting from the leaf tip, with a purplish-red edge at the boundary between the diseased and healthy tissue, after which the spots spread downward and the leaves turn withered and yellow. For control, spray with a 50% Tuzet (thiophanate) 1000-fold dilution, applying the spray once every 7-10 days for 2-3 consecutive applications.

Methods and Technical Key Points for the Prevention and Control of Pests and Diseases in Polygonatum
(1) Black spot disease occurs mostly in spring, summer and autumn, and damages the leaves. Control methods: clean the garden at harvest time to eliminate diseased plant residues; in the early stage, spray 1:1:100 Bordeaux mixture once every 7 days, for 3 consecutive times. (2) White grubs damage plants in the larval stage, attacking the roots, biting off seedlings or gnawing the seedling roots, causing broken seedlings or cavities in the roots, and the damage is severe. Control methods: seed dressing with 75% phoxim emulsifiable concentrate at 0.1% of the seed amount; or during the field occurrence period, drench with 90% trichlorfon at 1000 times dilution.
