A Detailed Guide to Practical Methods for Identifying Estrus in Foxes, Raccoon Dogs and Mink
I. Estrus identification in foxes: For the fox estrus period, the silver fox (silver-black fox) is generally from mid-January to mid-March; the Arctic fox (blue fox) is from mid-February to late April. Estrus in male foxes is easy to determine. A male fox entering estrus is active, drawn toward the opposite sex, has reduced feed intake, urinates frequently, and the "fox scent" in its urine becomes stronger. When a female fox is placed with it, the male shows great interest, continually mounting the female, and if the female is in estrus, mating is successfully achieved. Estrus identification in female foxes is relatively complicated; commonly used identification methods include the vulva observation method, the pair-pen teasing method,

What to Do When Jujube Seedlings Wilt? A Detailed Guide to Practical Solutions
Recently, many farmers have reported that some jujube seedlings planted this spring gradually wilted when their new shoots grew to 10-20 cm, until they dried up completely. Our analysis suggests: 1. From the perspective of climatic conditions, this is related to this year's unusual climate, such as low temperatures and sandstorms. In mid-April after the jujube seedlings were planted, our city experienced a period of low-temperature weather lasting about a week, with the lowest temperature below 10 degrees. The low ground temperature caused poor root activity, and the frequent sandstorms this spring also caused excessive transpiration in the newly planted jujube seedlings, resulting in water loss and wilting.

Two Practical Potato Processing Techniques Explained in Detail
1. Jam Making Recipe: 4 kg potatoes, 4 kg granulated sugar, 10 g citric acid, a small amount of carmine red pigment and food flavoring, 2-3 g sodium benzoate. Method: First wash the potatoes, steam them until cooked, peel them, spread them out to cool, then mash them into a paste with a pulping machine. Then pour the granulated sugar into a double-layer pot, add an appropriate amount of water and boil to dissolve, pour in the potato paste and stir so that the potato paste and sugar water are mixed, continue heating and stir constantly to prevent scorching. When the slurry temperature reaches 107°C-110°C, use citric acid water to adjust the pH to

Pre-storage Treatment of Potatoes and Several Practical Storage Methods Explained
1. Pre-storage treatment Pretreating the tubers before storage can inhibit potato sprouting and plays a very good role in ensuring storage results. (1) Sun-drying After harvesting, potato tubers can be spread out in the field to dry briefly, releasing some moisture to facilitate storage and transport. Generally, sun-drying for 4h can significantly reduce the incidence of disease during storage. If sun-drying lasts too long, the tubers will lose water and wilt, which is unfavorable for storage. (2) Pre-storage Potatoes harvested in summer coincide with the hot season; after harvest, the potato tubers should be piled in a cool, ventilated room, cellar or shade shed for pre-storage. For

New tricks for mushroom processing, these practical methods are worth a try
Mushrooms are a nutritious and healthful food that people love. With the large-scale development of mushrooms, new processing methods have emerged. 1. Mushroom pickles - salted base: Remove debris from the mushrooms, wash and drain them, prepare brine at a ratio of 10-15 kg of salt per 100 kg, place the mushrooms in the brine until just submerged, seal and salt for 1 week, turning them twice during this period so the salt penetrates evenly. In soy sauce: Take out the mushrooms, drain off the brine, soak in clean water for one day, remove and dry the surface moisture, then put them into a sauce jar, and use 50-70 kg of sweet bean sauce per 100 kg

Practical Methods and Technical Points for Anti-Aging of Mushrooms
1. Soaking in clean water: Water can block out air, slowing down the discoloration of mushrooms and keeping them plump. However, the water must have a low iron content; do not use iron containers or water with a high iron content for soaking. 2. Sodium metabisulfite treatment: First rinse the mushrooms with a 0.01% sodium metabisulfite aqueous solution for 3 to 5 minutes, then soak them in a 0.1% sodium metabisulfite aqueous solution for half an hour, remove and drain, and store in plastic bags. At a room temperature of 10°C to 15°C, the preservation effect is good, and the mushrooms can remain white for a long time. However, when the storage temperature exceeds 30°C, they can only be preserved for 1 day, after which they will gradually discolor.

How to Store and Keep Mushrooms Fresh? All the Practical Methods Are Here
Mushrooms are best eaten fresh, but since they do not keep long under natural conditions, especially when mushrooms are cultivated on a large scale, storage and preservation techniques can extend the selling period or allow them to be processed into canned products and other goods for export earnings. Here are several storage and preservation techniques for mushrooms: 1. Cold storage preservation. After the harvested fresh mushrooms are sorted, place them in containers such as baskets, trays or hampers and cover them with multiple layers of damp gauze or burlap. In a cool, shaded place, set out a vat filled with a small amount of clean water, place a wooden rack above the water, set the baskets or hampers holding the fresh mushrooms on the rack, and then seal the mouth of the vat with plastic film.

How to prevent and control gray mold in carnations? These methods are very practical
Carnation gray mold, also known as carnation flower blight, is a common disease of carnations grown in greenhouses and plastic tunnels. The disease damages the petals of the plant, causing brown spots and rot on the petals, and seriously affects the quality of cut flowers. Symptoms: The disease mainly occurs on petals and flower buds, and occasionally stems and leaves are also affected. In the early stage of the disease, affected flowers begin to show light brown water-soaked areas from the petal edges, and then several petals become tangled together by gray fungal growth. In the later stage of the disease, if the environment is humid, the petals rot, and a gray

Three methods to increase soybean yield, simple and practical
Thinning: After soybean seedlings emerge, thinning early on the basis of a full stand is a proven yield-increasing measure. Its effect depends mainly on how early thinning is done; generally it should be carried out promptly when the two opposite unifoliate leaves have unfolded. Seedling pressing: When the first compound leaf of the soybean seedling has unfolded, choose a sunny noon and press the seedlings along the rows with a wooden roller drawn by animal power or machinery. When pressing, be careful to avoid cloudy days or sunny mornings, so as not to break the seedlings. Pinching: At the early flowering or full flowering stage of soybean, remove about 2 cm from the top of the main stem by hand.

How Does Soybean Cultivation Improve the Soil? A Detailed Guide to Practical Techniques
1. Soil Conditions for High-Yielding Soybeans Soil conditions are the foundation of high soybean yields. Soil moisture status, nutrient status, and certain physical properties of the soil are important factors affecting soybean yield. Soybean seeds require more moisture to germinate than cereal crops. Soybean seedling roots are relatively tender and high in water content, so suitable soil moisture conditions are needed to promote deep elongation of the young roots. The main root of the plant can reach about 1 m, and lateral roots can extend horizontally to about 0.5 m. When soil moisture is insufficient, both vertical and horizontal root growth are affected.
