How to prevent and control jujube fruit shrink disease? A full analysis of the key technical points
Jujube fruit shrink disease is a new disease of jujube trees, often occurring together with anthracnose. When this disease breaks out severely, it causes reduced yields in mild cases and total crop failure in severe cases, and in recent years it has caused huge losses in the jujube-growing areas of our city. The disease mainly damages jujube fruit, causing fruit rot and fruit drop. It occurs during the coloring stage of jujube fruit; in our city it begins in mid-to-late July, and mid-to-late August is the peak period of the disease. Affected jujube fruit first shows a pale yellow halo on the fruit shoulder and body, which then gradually expands into round or irregular water-soaked discolored lesions, with a round brown spot in the center; the flesh in the diseased area

Fox Feed Formulation Methods and Technical Key Points
The fox is internationally recognized as one of the precious fur-bearing animals, and it is raised in many countries around the world. It is a carnivorous monogastric animal, and feed must be formulated according to its nutritional requirements, feeding standards, and locally available feed conditions. At the same time, attention should be paid to the complementary effects of proteins in various feeds, their physicochemical properties, and so on, in order to improve the nutritional value and utilization rate of the feed. (1) Daily feed for foxes 1. Animal-based feed: includes various small trash fish, livestock and poultry offal, and various wild small animals such as rats, earthworms, maggots, frogs, and so on. Fish meal can also be used.

Key Technical Points for Raising and Managing the White-Banded Snake
Snake farming is a path to prosperity with low investment, high returns, and quick results. At present, domestic snake farming is mainly focused on the medicinal white-banded snake. I. Site Setup for Domestic White-Banded Snake Farming 1. Indoor rearing. The walls and wall foundations of the snake house must be paved with cement or asphalt to prevent rats from burrowing. The door must be seamless, the walls must be painted smooth, and the wall height must be above 2 m to prevent the snakes from escaping the snake house and injuring people outside. A water dispenser should be set up indoors to continuously supply clean drinking water, which helps the snakes shed their skin. 2. Outdoor rearing. This allows more

Artificial Keeping Methods and Technical Key Points for the Chinese Cobra
The white-banded snake, also known as the many-banded krait or the small-banded krait, has high medicinal and economic value. Its keeping methods are as follows: 1. Build reasonable pools. The snake pool is built of brick and stone, 2 m square and 1.5 m high, and can hold 15-20 snakes; putting in too many snakes makes management difficult. The pool walls are smoothed with cement, and a movable glass cap is added on top of the wall in a T shape to prevent escape. The bottom of the pool is the snakes' activity area, where weeds should be planted, and then snake nests should be built with sand, wooden boards, bricks and tiles, etc. Build a flowing water ditch and a bait basin in the pool, and cover the pool with

Methods and Technical Key Points for Pest and Disease Control in Phalaenopsis (Moth Orchid)
Doing a good job of pest and disease control is an important part of successfully cultivating Phalaenopsis. Disease prevention is routine work: the growing environment must be well ventilated, the potting medium and air humidity suitable, and Bordeaux mixture, chlorothalonil, thiophanate-methyl and similar chemicals sprayed regularly to prevent disease. Once pests or diseases occur, apply chemicals promptly for control. I. Main diseases and their control: 1. Petal gray mold: black mold spots form on the petals, and mycelium can be seen on the mold spots. 2. Anthracnose: large dark brown or light brown oval or irregular lesions grow on the leaves, and on the lesions

Preliminary Study on Propagation Methods and Technical Key Points of Taxus wallichiana var. mairei
Taxus wallichiana var. mairei, also known as beautiful yew, shan gongzi, and hailuo pine, is a rare evergreen tree under first-class national protection. It has a graceful form, with a purplish-red, straight trunk, and when the seeds mature they turn red, with a vividly colorful aril. It has strong regional adaptability and can be planted anywhere south of Shaanxi. This tree species prefers a humid and cool climate environment, and is suitable for growing in moist, loose, well-drained acidic to slightly acidic soil. It is a semi-shade-tolerant species; seedlings tolerate shade and grow slowly, with growth increasing after 3 years. Because it also tolerates poor soil and has strong resistance to pests and diseases, it is the preferred species for reforestation on mountain land in East China after pine species

Propagation Methods and Technical Key Points for Taxus wallichiana var. mairei (Chinese yew)
Select a suitable nursery site: choose a fertile, loose, neutral or slightly acidic soil plot with good drainage, preferably a fertile plot within woodland or in semi-shade. Apply ample base fertilizer, rake level, and prepare the seedbed ready for planting. Seed propagation: seeds mature in October; after timely harvesting, place them in a mixture of water and fine sand (water-to-sand ratio 2:1). Rub the seeds on a washboard to remove the outer seed coat and wear down the hard fleshy seed coat. Choose a shady, dry plot with no water accumulation, dig a pit, and store the seeds mixed with wet river sand at a ratio of 1:2 in the pit. In March of the following year, take out the cleaned seeds and soak them in 50-degree baijiu and 40

Detailed Explanation of Key Technical Points for Dehydrated Shiitake Mushroom Processing
1. Process flow: raw material selection → sun-drying → oven-drying → grading and packaging → finished product. 2. Operational key points. Material selection: shiitake mushrooms used for drying should be selected at moderate maturity, intact, free from disease, insects and damage; they are generally harvested when the caps are 80% mature. Sun-drying: after harvest, place the shiitake mushrooms on drying trays with the stems facing down and sun-dry them in sunlight; the time depends on the moisture content of the raw material, generally 5-8h. Oven-drying: oven-drying can be carried out in a drying room or a dehydrator. Temperature control during the oven-drying stage. Grading: after oven-drying, the shiitake mushrooms should be graded promptly. The grading standard

Key Technical Points for Shiitake Mushroom Mycelial Growth and Soaking Management
After inoculation, the mycelium begins to germinate and colonize from days 1-6. At this time, the bag temperature is 1-3°C lower than the room temperature. The room temperature can be controlled at 28°C, and the indoor relative humidity should be kept below 70%. From days 7-15 of mycelial growth, the mycelium germinates and grows 4-5 cm. It is necessary to check whether the mycelial growth is normal. If contaminating microorganisms are found, promptly remove them from the cultivation room for handling, and maintain the room temperature at 24-27°C. Pay attention to ventilation. From days 16-25 of mycelial growth, the mycelium becomes interconnected. Remove the mycelial strips to allow oxygen to enter directly into the depths of the bag. After oxygen is introduced, the mycelial temperature rises rapidly within 12 hours.

Detailed Explanation of Shiitake Mushroom Storage Methods and Key Technical Points
After shiitake mushrooms are dried, they easily absorb moisture again if not stored properly. This is especially true during the rainy season when temperatures are high and humidity is great, making mold and insect damage more likely. Therefore, after drying, the shiitake mushrooms should be quickly graded and packed into plastic bags, and a small packet of anhydrous sodium chloride should be added to prevent the sugars in the mushroom body from seeping out and causing discoloration. At the same time, to prevent insect damage, the storage room can be fumigated with sulfur disulfide for 24 hours before storage, and storage should begin only after the residual gas has been expelled.
