  • Control Methods and Technical Key Points for Garlic Viral Disease

    The garlic planting area in Eryuan County is over 30,000 mu, with an output value exceeding 100 million yuan. In recent years, due to continuous planting, viral disease has occurred widespread, leading to variety degeneration, decreased yield and quality, and seriously affecting the income of garlic farmers. 1. Disease symptoms: In the early stage of the disease, yellow striped markings appear along the leaf veins, plants become dwarfed, new leaves do not extend properly and are distorted. When the disease occurs after bolting, the parts below the flower bud of the garlic scape gradually lose green color and turn white. Plants have few fibrous roots, and in severe cases the garlic bulbs become smaller and hardened. 2. Environmental conditions for disease occurrence: Mainly the garlic seed carries the virus. During the seedling stage

  • Key Technical Points for Spring Fertilizer and Water Management of Garlic

    After garlic turns green again, its absorption of fertilizer and water gradually increases. Especially during the bolting stage and the garlic bulb enlargement stage, these are the peak periods of fertilizer and water demand. In terms of management, emphasis should be placed on watering the "three waters" well and applying the "three fertilizers" well. Water the green-up water well and apply the green-up fertilizer well. In spring, the soil temperature is low, so it is best to water the green-up water at noon to promote early seedling growth. Along with watering, apply 15-25 kg of nitrogen-phosphorus-potassium compound fertilizer per mu or 15 kg of potassium sulfate, then control water appropriately to promote root development. Water the bolting-promoting water fully and apply the bolting-promoting fertilizer heavily. Late March to early April is the period of rapid differentiation of garlic flower buds and clove buds

  • Key Technical Points for Spring Field Management of Garlic

    Water and fertilizer management after garlic turns green again 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 enlargement stage, garlic has its peak demand for water and fertilizer. Therefore, throughout the entire growth period of garlic, irrigation and topdressing should be carried out in a timely manner according to soil moisture, soil fertility and seedling conditions, with particular emphasis on watering the "three waters" well and applying the "three fertilizers" well. 1. Water the greening water well and apply the greening fertilizer well. By the Spring Equinox, garlic seedlings begin to turn green and grow. Because early spring soil temperatures are low, it is best to water the greening water at noon

  • Detailed Explanation of High-Quality Cultivation Methods and Technical Key Points for Export Garlic

    Export garlic has relatively high quality requirements, and only by adopting scientific cultivation methods can garlic quality be ensured. 1. Sowing: Choose soft, fertile, well-drained sandy soil. Before planting, water, plow and harrow, and apply sufficient farmyard manure such as cake fertilizer and human excrement and urine. Plots whose previous crop was scallions or chives are not suitable for planting garlic. Select seed garlic that is medium in size, has few cloves, and is free from mildew, rot, damage, or insect damage for sowing. Clove-gapped garlic cannot be used as seed. Sow around the Autumn Equinox. Use a narrow hoe to open shallow furrows for dibbling, then cover with soil and level it, requiring consistent depth. 30,000 plants per mu, with a plant spacing of 11.7-13.3 cm and a row spacing of 2

  • Guangdong White-Banded Snake Rearing Methods and Key Technical Points

    Climate and environment: It favors a mild and humid climate, preferring shade and fearing sunlight. The optimum temperature is 25-30°C. When the temperature drops below 10°C, it enters hibernation. It likes to inhabit environments near water with grass and shrubs. It is active at night. For the rearing site, choose a mountain-side plot that is sheltered from the wind and faces the sun, warm in winter and cool in summer, and build a rectangular or circular enclosing wall, 1.7-2 m high, with the inner side plastered smooth and no holes left, to prevent escape. Inside the wall, build a snake room and a pool, and leave an activity area. The size of the snake room depends on the number being reared; generally 1.5-2 m long and 0

  • Raccoon Dog Feed Processing Methods and Technical Key Points

    Raccoon dog feed includes animal-based feed, plant-based feed and supplemental feed. The supply and composition of feed have a great influence on the health, reproduction and fur quality of raccoon dogs. To practice scientific raccoon dog farming, one must understand the effects of feed nutrients on raccoon dogs, so as to reasonably and correctly formulate and process feed, and obtain the best economic benefits with the least feed consumption. Therefore, the processing and preparation of feed is very important. (1) Processing of fish and meat feed Fresh marine mixed fish, meat, liver, kidney, heart and fresh blood of healthy animals, etc., remove large pieces of fat, fully wash away soil and impurities, then mince and feed raw. Fish and meat feed of poorer quality but still usable must first be fully washed with clean water, then soaked and disinfected in a 0.05% potassium permanganate solution for 5-10 minutes, and washed again with clean water before being minced and fed. Severely spoiled fish and meat are prohibited from being processed and used. The intestines, spleen, lungs and other offal of freshwater fish and poultry must be fed cooked. Cysticercus-infected pork (measly pork) can be processed and used after high-pressure steaming or thorough cooking and removal of fat. Fish meal and meat-and-bone meal should be soaked for 3-4 hours, with water changed 2-3 times, to remove excess salt before being mixed with other feed and fed. Blood meal and liver residue meal should be steamed and cooked before use. Silkworm pupae should be fully soaked, de-alkalized, then steamed, cooked and minced before use.

  • How to cultivate high-temperature oyster mushrooms? Detailed explanation of key technical points

    Late spring and early summer is a good time to cultivate oyster mushrooms. Because high-temperature oyster mushrooms fruit during periods of high air temperature and are prone to many diseases, the planted quantity is relatively small, but their price is 2 to 3 times that of the autumn-winter period. High-temperature oyster mushroom cultivation is technically difficult and the success rate is extremely low, so how to obtain high quality and high yield is a matter of greater concern to mushroom growers. Variety selection Many mushroom growers fail in cultivating high-temperature oyster mushrooms, mostly due to mistakes in variety selection. Some growers do not clarify the temperature type of the variety and plant casually, resulting in no fruiting or failure of mycelial growth because the temperature type is wrong, so it is essential to obtain spawn from

  • Oyster Mushroom Soft Rot: Control Methods and Key Technical Points

    1. Culture material treatment: choose fresh cottonseed hulls or corn cobs as raw materials. Before mixing the material, it should be exposed to the sun for 2-3 days, or ultraviolet light should be used to kill some of the contaminating microorganisms in the culture material. During fermentation, strictly follow the fermentation process to ensure it is thorough, even and complete. Products such as warming fermentation agents, Lixin Junwang or Kemei Wang can be added to improve resistance to contaminating microorganisms. 2. Management during the spawn-running period: when cultivating large bags for fruiting, they should be placed in a cool, ventilated and clean location. Try not to cultivate them inside the mushroom house (shed), to avoid the growth of large amounts of contaminating microorganisms during the mycelial cultivation process, which can lead

  • Key Technical Points for Summer Management of Gastrodia elata in Northern Shaanxi

    Gastrodia elata prefers to grow in warm, moist sandy (or leaf-mold) soil and has relatively strict requirements for temperature and humidity. However, the area along the Great Wall in northern Shaanxi lies in the mid-temperate zone, where summers are hot and dry with little rain, which is unfavorable for the growth and development of Gastrodia elata. To achieve a good harvest of Gastrodia elata, the measures that should be taken in summer management are: (1) Build a shed for shade. In summer, especially at noon during the hot dog days, due to direct sunlight, the ground temperature at 20 cm below the surface (already close to the Gastrodia elata layer) reaches as high as 30-37°C. To keep the ground temperature at 20-28°C
